Comment by gandreani 10 hours ago

A lot of people are focusing on how irresponsible the engineer was about using the work computer. That's obviously an issue but the bigger failure mode to me is the Engineer C's container deployment token.

That's a huge red-flag. In a company of this size, the deployments should be via CI only. CI isn't just to increase the speed and reliability of deployments but also to provide a clean room to build the software! Even if it's a token that was copied and pasted temporarily, the systems in place should not have to require this type of 1. copy 2. paste 3. remember-to-delete the token from my PC.

Also, Binance should be paying for intrusion testing. Better to pay a trusted company to do this kind of thing instead of letting North Korea show you how it's done. I don't think this exact exploit path would have been found but I bet the intrusion testing would have figured out another way to use Engineer C's token.

Nobody in the entire company should have access to move $billions in crypto, much less a random engineer, even if they're part of the deploy process.

They had controls in place to prevent large transfers, so the attackers structured it as a lot of small transfers very quickly

Comment by melenaboija 2 hours ago

Well, then they need another control that prevents “small transfers very quickly” happening, I guess.

Comment by yobananaboy 7 hours ago

Not just that! The EIP-7702 delegation to make the wallet into a smart contract bypassed all of the controls that they had in place on the signer. It's wild that they didn't have a system in place to stop it from signing that transaction type.

Comment by tennysont 4 hours ago

From my rough understanding, this seems like the main exploit. It seems like the machine with access to the wallet key was presented with a crazy EIP-7702 transaction and signed it (which effectively owned its wallet in a single transaction)[1]. Without knowing their security model, it seems like biggest trust boundary should be between that signing machine and everything else.

[1] The fact that the needed to sign 50 of these transactions to solve a race condition seems like an implementation detail

Is quorum signing not a thing in crypto?

Comment by cowlevel 4 minutes ago

In Ethereum it would be implemented by overriding your account with a smart contract, the approval of which is exactly what they signed here (only it wasn't a multisig smart contract, it was something malicious).

Also Superman III, which predates it and presumably was well known to the writers. But I have an inkling the scheme and it's infamy go back much further. (Precious metal coin clipping/debasement?) It's one of those ethical questions, like a pauper stealing bread, or thought experiments, like "what if reality is just a dream" that many if not most people encounter during their formative years. Per usual, though, the chasm between theory and application (even just identifying real world potential when it matters) is the toughest one to cross.

If they did and didn't account for a simple scenario like this happening and built in roadblocks and friction to prevent it from happening? Then it would stand to reason their entire EIS team should be fired.

One of the first things I did in my last job was shift processes like this off my team's computers, aside from the security ramifications all it takes is one dumb mistake, one up-arrow too many, one didn't-read-the-whole-line, and now you're doing something to production by accident!

I also did that, for a team deploying smart contract on chain from local.

It took a couple months to get the pipeline out of their laptop.

Worth it, yes, as we found interesting things in there which explained why they were so reluctant to deploy upgrades.

No, rather a particular environment with monkey patched libraries, alias for various versions of compliers, and dozens of env variables that happen to work or not work well with the desired config.

What sorts of processes related to secret storage were you able to shift off of team computers? From my perspective, if I need to get e.g. an API key from Twitter and put it into my prod environment, i have to be doing that with my computer somehow. There's still millions of different types of secrets that need meat puppets to shuffle them around.

Yes. The situation improves considerably if, when making server changes or retrieving data, programmers are required to enter a code generated from a hardware TOTP token isolated from both PCs and smartphones.

Every service provider system should be designed with the assumption that programmers' PCs and smartphones may be compromised.

Comment by yubblegum 6 hours ago

The article says that a software engineer interviewed with the North Koreans and the NKs then gained access to engineer A's machine (which had the deployment token) and then finally passed that token to run on engineer C's machine (who apparently did deployments). They knew of the team makeup from their first (caught) attempt.

That unlettered (npi) engineer who downloaded and ran the interview software on his or her machine is what the human weak link here. Let's call them Engineer F. Seems like this person was specifically selected from the dev team.

Comment by saalweachter 2 hours ago

One of my favorite stories from a security talk was the speaker recounting the surrealism of (while doing a forensic investigation of a security incident) watching the attacker read your internal documentation to try to figure out how the hell anything works mid-attack, and running into all the same pitfalls as your new employees.

Comment by burningChrome 5 hours ago

I've had this happen a few times getting interview requests from Indian recruiting firms. It sounded familiar. You go through a screening, then get passed onto the "code challenge" part. You have to download a GitHub file and then work on it, check it back in and push it so they can examine what you did.

Twice I scanned the file after downloading it to a sandbox and twice it found malware that would've been installed.

While this is by far the worst case of this happening, I've read at least a half dozen other accounts of recruiting companies attempting to install malware through the same process. I'm not saying the person should have known, but it's scary this is becoming more and more common.

Comment by fc417fc802 2 hours ago

> I'm not saying the person should have known

This person definitely should have known. You don't download and run arbitrary binaries outside of a VM. At this point you don't even compile code from an untrusted source. This is the power user equivalent of falling for a phishing email.

No such thing as deleting secrets. You decommission them and replace them. Deleting them off disk is impractical to do, at least sufficiently.

100% this. I can deploy to our sandbox environment directly, but only our CI/CD has the permissions to build/deploy to our master environment. And the stuff I work on is 1000x less impactful than $billions in crypto!

Comment by AlexITC 10 hours ago

I have saw companies doing social engineering as part of their intrution testing, I imagine fake interviews are (or will become) part of these.

Comment by Aurornis 9 hours ago

I think it will remain uncommon. I agree it would be a good test, but companies and employees alike get very angry when pentesting gets too close to sensitive subjects.

Anyone who fell for it would not only get in trouble for poor security practice, they would reveal that they were job searching. That opens an entire can of worms that creates problems beyond the pentest. This also angers other employees who see it as a double-trap being sprung on employees.

Another major problem is that responsible employees who accept the fake interview but then use their personal laptop to do the interview will have their personal laptop compromised by the pentesters. Responsible testers will immediately abort, but some will try to use the personal laptop to pivot deeper which is a huge ick. It’s also really bad if the company is compromising personal laptops of people who are doing the right thing (switching to personal gear for interviews).

Comment by fc417fc802 2 hours ago

> responsible employees who accept the fake interview but then use their personal laptop to do the interview will have their personal laptop compromised by the pentesters.

If your laptop is successfully compromised by the pentesters then pretty much by definition you weren't being responsible. Though I agree that pentesters going after personal devices is ethically dubious.

Comment by Aurornis 56 minutes ago

Compromising employee personal devices is strictly out of scope for any security testing I've seen.

> Though I agree that pentesters going after personal devices is ethically dubious.

It's not just ethically dubious. It crosses a lot of legal boundaries. A company can consent to have their personal devices hacked. An employee doesn't automatically consent to let a company's contractors access their personal devices.

The pentesters wouldn't have to actually pwn a laptop, just getting the employee to download and run anything could go in a report without having the file actually be malicious.

Hired oentest has company permission to do stuff on company property. I do not imagine they have right to do so to personal property.

Absolutely not. There is literally no framework, which would give you the right to exploit an employee’s personal laptop, that’s just cyber crime.

Comment by realo 7 hours ago

Then that is something the pentesters cannot do, but malicious actors will do.

Game over.

Comment by PeterisP 4 hours ago

What pentesters can do, should do, and often do is simply start the test from a workstation that is given to them - you assume a successful social engineering attack as the starting point, and test whether your process and technical controls can properly limit the impact of such a compromise without trying to replicate the actual social engineering step and the associated disruption to the targeted employees.

Taking over that first engineer's workstation shouldn't ever have resulted in $6.3B of damages. I would consider it reasonable if those privileges could be abused (by e.g. the same engineer intentionally) to cause $6.3M of damages and the rest would be mitigated or prevented; so for this incident we could say that 0.1% of the impact was caused by the initial compromise of that workstation and 99.9% of the losses were caused by all the other failures - so it's effective for any pentest to focus on the latter part, ignore the social engineering and phishing part (since you can't really eliminate it anyway - unlike many other flaws) and assume initial compromise as a starting point.

Comment by thomc 9 hours ago

Sometimes called "Full Spectrum Attack Simulation" where initial entry can include physical access or spear phishing. They can span months in elapsed time (not effort) so as to be more realistic. However there are still ethical and safety constraints and even phishing may not be able to use the (effective) technique of stressing the recipient too much or of course blackmail or coercing. So I think fake interviews may not be allowed in many cases, to protect the employees.

"fork this repo and fix this bug" is a common job interview request, isn't it?

For many build chains, that involves implicitly installing software.

Comment by fc417fc802 2 hours ago

Such toolchains are dumpster fires whose use invites supply chain attacks. They should never have gained mainstream acceptance and should never be run outside of a sandbox.

That said I wouldn't trust a compiler to be hardened against malicious input and anyway you presumably need to run the output so all of that should be happening in a hardened sandbox regardless.

It's easy for me to say from the comfort of it not being my job on the line, that if this happens to anybody they should quit and then name and shame the company, but a competent security team is going to have the idea of doing a fake phishing interview and then not do it because of how morale destroying that would be. The security awareness team sending fake phishing emails are embarrassing enough.

Comment by WesolyKubeczek 9 hours ago

What if I plant a hook on the engineer’s laptop that will slightly modify their commits in such a way that eventually I smuggle malicious code over? First, exfiltrate the code over to me, learn from previous commits, start poisoning. Stamped by the CI, no less. In the days of slop PRs thousands of lines each shouldn’t be even too hard.

The point is that at some point you do need to open the door and let the code in.

Comment by paxy 10 hours ago

In my last job we used Zoom for interviews. The link we sent would work in any web browser, but if the candidate was signed into a Zoom account on their computer we'd be able to see it. I'd say >70% of them were on their company account.

Even worse when you have to do stuff like screenshare or coding. I've had candidates share their screen and have obvious proprietary material in open windows. I've seen countless email inboxes and calendars. I've seen candidates do coding exercises using internal IDEs, dev environments and dev tools. I've had them talk – fully unprompted – about internal tech and unreleased projects. And I'm talking about Google, Meta, Amazon, Coinbase, Uber.

At this point I'm convinced that a large chunk of tech interviews are happening just to extract insider info from employees.

Anecdotally, I've also seen the same thing, and _done_ the same thing (on the zoom accounts). A previous companies policy allowed for zoom logins on non-corp devices so that you could take a late call from home. The only thing I _ever_ use zoom for is work or interviews, so it's not like I'm going to log out after?

This is more of an amusing story, but it kind of fits ...

I have a relative who started (what has become) a successful winery.

During the first few years he worked on the winery on nights/weekends, but he kept his day-job as a finance guy at a relatively large company.

He told me he had to give a presentation at the company one day, plugged his laptop into the conference room projector and up popped a spreadsheet of wine-making measurements (pH, temperature, % alcohol, etc.). He said everyone in the room laughed.

I immediately fired up the company's copy of Word to draft up a resume, and used the company computer to send the email from my personal account. Less than a month later, I was working for the new company. It was done intentionally. I almost sent the resume via company email, but I really wanted to ensure I could access any response.

Comment by alyeska2 8 hours ago

That's a very uncommon mindset and worldview.

For 99% of people, the default would be "I'm going to join this Zoom meeting from the laptop I use all day long to join Zoom meetings, and I'm going to code using the laptop I use all day long to code".

Lots of people have their work tools setup on their work computer, but not on their personal computer. Their personal laptop might be relatively underpowered and struggle to run all the required software efficiently during an interview. The issue becomes even more significant as more of the tools used require an account - you don't want your interview performance to suffer because you're using an unfamiliar tool or service, so you just use the ones you're used to using every day.

Comment by JsonDemWitOster 7 hours ago

What I'm seeing here is that Binance has the IT culture of a SV start-up when it should have the IT culture of a bank. Sounds to me like a thug with a $10 wrench could've been just as effective.

> Lots of people have their work tools setup on their work computer, but not on their personal computer...you don't want your interview performance to suffer because you're using an unfamiliar tool or service...

I struggle to come up of even the most absurd interview scenario where the tool makes the difference especially in our field where if a FOSS tool is not standard, then there's a sufficiently powerful free tier (eg., Sublime, IntelliJ). Heck most remote interviews, they take you out of your tools completely and ask you to code on some shared browser-based editor.

> That's a very uncommon mindset and worldview.

I'm calling HN SV start-up bias. Outside of the startup software eng'g industry, a lot of people exercise very good separation between work tools and personal tools. I know a lawyer, _who's the head of his own law firm,_ bring his personal laptop to the office just so he could purchase tickets during office hours.

I think this is also down to a few factors:

- SWEs are typically issued high-end machines in contrast to other professions whose standard issue is still 4GB (or 8GB, if you're lucky) RAM. For those professions buying a better personal laptop is a low bar to clear.

- SWEs are more efficient when they have admin access to their own machines. Though it begs the question that maybe some inefficiency would've been an acceptable tradeoff to $6.3B.

- SWE is one of the professions on the poster for the "Get paid good while working from Bali" lifestyle, wherein BYOD is implied, especially if you are freelancing.

Comment by alyeska2 6 hours ago

> I struggle to come up of even the most absurd interview scenario where the tool makes the difference

I had an interview recently where I'd initially planned to use my own machine, then gave up and just used my work computer.

I'm used to the whiteboarding/UML/flowchart software I use at work, so I either needed to pay for a personal subscription so I could use it in the interview or be forced to use some other software I'm not familiar with. I also didn't have a personal paid AI code tool, so again either pay for a personal one or just use the work Claude account. Also the webcam on my work laptop is substantially nicer than my personal laptop.

Also, critically, it doesn't matter. If IT or my manager had pinged me to ask "Did you do an interview at noon yesterday?" I would have said yes and then the only follow-up would have been them asking if it was a random thing or if I was actively looking.

I think IT (and I guess, lawyers) are probably the only people who care much about separating work and personal devices, just because they're prone to being aware of how much surveillance of the device can be happening. People in marketing/sales/whatever back office stuff will be logged into their personal Facebook, Netflix, iMessages, Email and bank and never consider that their keystrokes are being logged and screenshots are being taken.

IT is aware of surveillance. Lawyers have a legal responsibility to take all reasonable steps to safeguard confidential client information. A lawyer misusing a work device is probably roughly equivalent to a healthcare worker doing the same.

Common or uncommon, its extremely unprofessional. You know when you are dealing with a kid or with professional who actually wants to get hired and has some manners.

Sharing other's company secrets by mistake, using other company's resources in ways that are definitely forbidden - is this a person you really want to hire since they will behave the same in your company? Is this a person you want to give trust with some internals?

In market with 100s or applicants thats enough to disqualify anybody who actually needs an interview or two to get hired.

Maybe this is just an agree to disagree moment, but literally no one I know would consider this unprofessional at all.

I've been in management for the past decade and interviewed a few hundred candidates in that time. Never once did I ask or care who owned the laptop they were using.

And similarly, if someone on my team used their work laptop for an interview, I wouldn't care at all.

If you work from the office, and they have tight security, they might frown upon bringing personal devices to connect to the internal network.

Also, some people might not have dev environments set up on their personal devices. Heck, a lot of people only use the internet through their smartphone, when they're not at work.

Comment by alexfoo 8 hours ago

For my most recent job (Staff/Principal SWE) I interviewed at four companies, each with four rounds of interviews (usual variations on 30m recruiter screen, 45m-60m tech discussion or coding exercise, 60m-90m tech deep dive, 30m-45m final wrap up with hiring manager). All over the course of about 3 weeks. It was about 16 hours in total.

No chance you can do that on "sick days", fake doctor/dentist appointments, or other such scheming. Taking many half days of personal leave just isn't workable either. You're not in full control of the scheduling to make different companies interview you one after each other on the same day, or take the same time between rounds. Some could have been scheduled in lunch breaks but not all of it.

Most people I've worked with would just schedule some "focus time" and were either WFH or headed off to a quiet part of the office or a nearby co-working space. Personal laptops are easier to use offsite obviously.

I usually refuse such Silicon Valey interview style, unless I am desperate for a new position.

For the ones I usually take, a few hours out from overtime budget is enough, or WFH days.

With 30 days holidays + overtime budget, taking a day off for an site interview, is manageable.

> Taking many half days of personal leave just isn't workable either.

Why it isn't? A genuine question, I presume this is more typical US culture or dare I say workaholism and various self-pressures to maintain some public office image?

I recently took quite a few half days off to manage workers doing bigger reconstruction in our apartment. Sometimes full day. Then smashed a week of vacation in Sardinia in between. Everybody understood whats happening, nobody cared since many went through similar exercise before.

Your time is your time, if you actually let it happen. Or you can spend your life living with servile attitude, nobody will thank you though.

Because my personal leave is time I want to spend with my family. I would have had to have taken about 4 days worth of leave (8 half days) to cover these interviews and that's 4 days a year less I get to spend with my wife and kids.

(UK based so not US culture, and not workaholism or image.)

Comment by cityofdelusion 9 hours ago

It does boggle my mind as well. I’ve only ever worked in high security industries as a developer, and I’ve never had admin access unless I was on hardware deployment. Limited user accounts, Firewall blocks, Active Directory audits, and full file system and network log audits are the name of the game where I have been. Anything external gets flagged quickly by automation and anything severe gets an immediate phone call. Falling for a pen tester phishing more than once, getting your laptop stolen, and so on can get you on the poor performer list. It just seems obvious for critical domains.

Comment by GoToRO 10 hours ago

Usually it starts with a locked down laptop, then request after request, you get more rights, even admin on the laptop because otherwise you can't do anything as a software developer.

Comment by Tangurena2 8 hours ago

Our (state) agency uses separate computer accounts for regular use and admin use. The admin account has neither network nor email access in order to prevent using the admin account on a regular basis. With state government agencies continually attacked with ransomware, we aren't as bondage and discipline as banks (which I have done before) or DOE (which was very severely extremely locked down and I was not connected to classified stuffs).

I have not needed admin credentials for regular development purposes since VB6 (which I was using until 2013). VB6 and ActiveX dlls required read/write access to the registry all the time.

I don't disagree but note that apparently a bank in France, Credit Mutuel (and it's Fortuneo online arm), just got robbed of hundreds of millions of EUR: hackers who have beforehand created accounts on Kraken (a cryptocurrencies exchange) and who then wired millions to different accounts, bought cryptocurrencies, and withdraw the crypto.

But the hack was really stealing hundreds of millions from the bank.

So not even banks are safe now.

My experience is completely different: many software developers are rather paranoid with respect to security, and have quite a good (though far from expert-level) knowledge about security. It's rather that many software developers are quite hostile to security practices that are mostly "security theater" and obstructs them in doing their work.

Around 2005, my employer at the time did a refresh of our it equipment, replacing all the cheap stuff we had been acquired with. They asked everyone to say if they need a laptop, as desktops were the default at the time. I said I didn't, and was surprised when he turned out that almost everyone else said they did. Most of them didn't really need one, and presumably were planning to use them for personal stuff.

The company was a bit salty about this as laptops are more expensive, but they got them. And of course the company befitted, as that was the end of a clear separation between work and home. You have your laptop, you can answer email and attend meetings with people in other time zones. Before, it was easy; work stuff stayed on work computers and those didn't leave the office when you went home.

I have a personal desktop because I grew up with video games and a desktop was always a personal investment.

Well, I managed to never use it, I don't take it with me, but there is a lot of effort in that.

In such a company I would give employees 2 laptops and 2 phones, one set for work only, one set for personal use only, then I would fire on the spot anyone mixing the usage. That would be a start in a longer journey of protecting the company.

If by "nothing to do with" you mean "uncorrelated", then this is very trivial and empirically untrue. There are a lot of tests that correlate with peer and manager-rated performance in software development (and many other roles).

Even the dumbest most ad hoc unrelated tests will have nonzero correlations, and the well-studied principled ones much more so.

The better argument is that tests are high effort and can feel demeaning. But it's not productive to pretend they don't work.

Ok, but there's no uniform grading in school or employment. We all know people who managed to get through university without learning anything and manage to hold a job in software development without knowing or doing anything. It'd be nice if a degree and a job history guaranteed competence, but it doesn't.

Lots of professions can bring a portfolio and/or a sample of their work, but most software developers can't because the work is often propriatary and a trade secret, and anyway would need a lot of specific setup to operate.

I've only taken test tests for government jobs, and they were laughably outdated; approximately nobody knew how much space was on a 5 1/4" floppy in 1998 when I took the test, but they were asking about 8" floppies, and I assume they still are, because the test had to go through some process and doing a new test would be expensive. But yeah, I expect a company to validate that I can both describe solutions to problems and turn that description into code.

They don’t take a test for every client. But they do get regularly monitored for their competency and instead of being fired when they fail, they have their professional license revoked.

Maybe IT professionals should be held to the same rigour. There’s a lot of deadweight in the profession that get paid too much and moan too loudly despite having a cushty job in a field they’re barely competent in.

Comment by gosub100 10 hours ago

It's also for liability. If someone comes in with the intention of suing them, they can point to the test and have objective evidence that the rejection was not based on race or gender. It also allows them to gather data after the employee gets established and succeeds or fails.

Also in the mid 90s, you actually had to be smart to work in this field. There was no stack overflow or reddit to search. And CS programs were nascent.

Companies certainly have taken it too far, but I don't blame them for some usage of standard tests.

They're constantly stretching what they can greedily get out of you; whether it's during the hiring phase or while being employed.

I remember doing 6 hours of interviews once for a company, getting to the final stage and they wouldn't budge on $5,000 for a figure they initially accepted but reneged because the manager hiring me would be paid less than me. It was so petty. I turned it down back then, but I'm not sure I would in this market. I'd probably take it and job search while I'm working there like this guy did at Binance.

I actually got contacted by North Koreans posing as Japanese VC looking to partner in the Nordics. I have an agent that scans my emails and does the inverse filtering, suggests when I should take a look. This is because I get insane amount of cold inbound. But it also flags suspicious emails and uses network tools to find out info about the sender. It flagged that one as a NK account (I later confirmed it was already flagged on the watch list in various reddit channels). Everyone should be arming themselves with email filtering agents now. What I’m worried about is grandmas and grandpas and general ppl that are behind the tech curve.

You meet the other side now and then. In my days at the aerospace company, we got an applicant from Russia with really good credentials from the Moscow Institute of Mathematical Sciences. They were really good in person, too. But the decision was "they had to be a plant".

I used to go to parties at Hacker Dojo in the early days of AI. Google wasn't into AI yet and Hacker Dojo had classes, often attended by Google people. (I learned way too much about support vector machines, in a class taught by a guy from BlackRock.) There were a lot of very good looking Chinese women at the parties who were very interested in what people were working on. They were very bright, understood the subject, and had business cards from small companies no one had heard of. Then one day they all disappeared and were not seen again. I regret not asking one how she liked working for the Third Department.

I just have Codex hooked up to the email client plugin and an hourly scheduled task. Then I have a prompt for selecting the ones I should read and flagging the suspicious ones. The prompt is combined with memory since Codex now understands what is important to me. For suspicious research I have my own skills with a bunch of "usual" tools, dig, whois, openssl client, curl, virustotal, and web research across reddit and a few other sites.

Anec-data - as an interviewer, last year, I had my first sketchy, perhaps 'North Korean', candidate.

The name on the CV, was, for the sake of privacy, Michael Smith, from Australia, and ticked the right boxes.

We'd expect a fluent, Aussie-accented English speaker. Instead, we had a candidate with a webcam that wouldn't work (weird!!), with clearly accented English of a East-Asian background. I suppose there's a vanishing chance they really were Mike Smith of Adelaide or wherever, but we couldn't take that chance. We tried rescheduling, but tumbleweeds...

Haha I had the exact same interview experience, the candidate was named Connor Wood, from Austin, TX. I actually told them we couldn't continue the interview unless they turned on their webcam. Cut to a meek east asian man in a dimly lit room. Are you sure you're the Connor Wood that played on the UT Austin Lacrosse team?? LOL I don't know how they expected that ruse to work.

You're going to have a hell of a hard time pulling off the "trustworthy" part convincingly, according to your very own words:

anal_reactor> Once I've been to an interview where first they made us solve a problem in a group and then we had 1-1 interviews. After the group task the guy immediately asked me "Don't you have a feeling that you might've been forcing your opinions onto others?" to which I replied "Yes, I have.". Absolute fucking Chad I was.

anal_reactor> If I died today, I wouldn't even get a slack memo "we miss anal_reactor". Modern economy proved that humans are totally fungible. I have a dream that someone would take me on a date. But I understand it's just a silly fantasy. I spent last two years at work doing projects that went nowhere because my manager is deaf to feedback. What is that even supposed to mean? If I don't pay taxes I'll go to jail. I tried inviting a neighbor for a beer. Didn't work.

anal_reactor> One painful lesson of my childhood was that coherent logic doesn't win arguments, telling people what they want to hear wins arguments.

anal_reactor> I've been investing heavily into IRL friendships but I understood that the dream of having a deep connection with someone is just a mirage. I don't see myself getting into a relationship even though I desire it a lot because I don't really believe there is someone truly compatible with me.

anal_reactor> I'm gay so I have easy access to sex and TBH I don't really have much sex, almost nothing at all, because sex with most people just isn't pleasant. I cannot derive pleasure from it if there's no connection, and "wow I love your car" isn't connection.

I have been getting these since early 2023, still, most of them are simple to spot, the other side typically has video turned off, asks a bit about your experience and just nods without digging, they are in a hurry to send you their coding challenge.

In one of these many calls I got to see the face from the other side but lasted a few seconds only. Then he claimed that internet was bad and suggested we continued without video.

In this case they claim it was a 2 rounds interview with video turned on to simulate a more normal recruiting process.

Of course all of us are prone to get caught with the shield off but what surprises me is that the targeted dev took the challenge in the device from work.

It's getting really confusing with these online job offers, including interviews and assignments. Various people are pretending to be recruiters.

Obligatory and should be obvious: a threat model that allows a single compromised laptop to result in a $6.3B loss is fundamentally flawed. Analyze the specific way that the laptop was compromised all you want, the fault here is entirely with the Binance security culture that allows such a gaping hole to exist in the first place.

I hope that Binance understands this and spends less time worrying about how the laptop was compromised and more time securing their systems under the very basic assumption that laptops will be compromised.

What surprises me most about the Binance hacking story is that Binance employees seem to have used their work laptops for some "programming test" (whose purpose was - as we now know - spreading malware).

I mean: if you even consider leaving your current company, you better leave no traces of your plan on your work laptop: you either use a private laptop or, even better, some burner laptop/computer that you reset afterwards.

Comment by moralestapia 10 hours ago

This is Binance/CZ's version of the story, but no one really knows the truth.

They have a massive incentive to invent a story to cover up the incident. I'm not saying it's a cover-up, but the motive is definitely there.

North Korea has denied responsibility, whereas they usually own up to their actions.

Disregarding that, it just doesn't make sense for their internal security to be so lax.

I've worked at big companies but with AUM lower than Binance, a lot of control and safeguards are in place to prevent one "rogue" employee from stealing everything.

It's pretty much impossible for a company like Binance to not have implemented such things. I do not buy it.

The lawsuits are coming, and the systems have logs. There is no incentive to lie about technical details that will come out in discovery in due course.

Comment by travisfromusa 8 hours ago

Don't forget that logs can be faked unless they are obtained directly by law enforcement forensic teams. In the case of Binance EU, their parent company is an offshore entity outside the direct reach of US and EU authorities. Consequently, anything Binance says or presents will most probably be taken as-is by western courts.

Another important note is that Binance has a strong incentive to cover up certain details, given that the company itself is anything but transparent. They also control CoinMarketCap, where they promote only projects that serve their own interests, while rejecting legitimate projects due to Binance's conflicts of interest. Several public reports and data document these practices.

There is no evidence given that North Korea did this.

"TRM attributes this attack to TraderTraitor, North Korea’s premier hacking unit. We base this assessment on robust on and off-chain intelligence sources. The FBI named the same group as responsible for the USD 1.5 billion Bybit hack in February 2025. Several features of this attack match earlier North Korea-linked heists, including the Bybit hack and the KelpDAO hack in April 2026: small Tornado Cash withdrawals funding an operator wallet, staging that began well before the theft, and signatures obtained in advance then executed in one burst. The laundering observed so far, built on large swaps through market makers and lending protocols, differs from the bridge-heavy pattern that followed Bybit. TRM will share further findings as the investigation develops."

https://www.trmlabs.com/resources/blog/north-korea-steals-us...

This is simply an assertion that an official enemy did something we don't like. It could just as well be a CIA money laundering scheme. This would make more sense, given the wider deployment of US cyber weapons and assets as well as the desire of North Korea not to provoke American aggression which previously murdered about 20% of their population.

It is widely known America has cyberweapons deployed around the globe. It is likely trivial for them to fake a trail of evidence from the DPRK.

It has gotten to the point where the advertised permanence of cryptocoin transactions is a serous national security threat, literally funneling $6+billion to a nation-state whose publicly avowed statements is to destroy the US to fund its nuclear weapons program.

This is already a reality. USDT, USDC, and many other smart contracts allow for the freezing of funds worldwide. Arbitrum rolls back its chain whenever it wants. State-sponsored Twitter influencers like Taylor Monahan (tayvano_), Zachary Wolk (ZachXBT), and Nick Bax (bax1337), falsely flagged as independent, publicly appeal to Thorchain (the only decentralized swap protocol between various native on-chain assets) to integrate transaction screening directly into the node consensus. EU has made accepting Monero illegal starting in 2027, among many other measures. Western governments have already succeeded in making crypto very controllable.

This was a big time process failure -- almost every company I worked for you have to authenticate with SSO and MFA and never have static credentials for important services like Github, Google cloud, etc. They don't seem to have least-privilege in place and if they did are not consistent about applying the policy to everyone.

I wouldn't be surprised if the guys they compromised were high-level staff engineers with the keys to the kingdom so to speak so they found a loophole. Security is hard because the attack only needs one chance to get it right -- and defense needs to get it right every single time.

This is insane. The first engineer ran some curl bash, which gave the hackers access to his Slack, and then they set up an interview for him at a fake company and during that interview, they convinced an engineer to download and install some code they had written? This is just clown world.

Yet another example of why you shouldn't use a work computer for personal purposes.

Move fast and break things. 4-eyes principle is for brick-and-mortar banks stuck in the prehistoric past of paper money. /s

It's strange companies haven't cracked something as basic as remote hiring checks yet.

There are tools available to stop AI screen recording tools, fake candidate tools yet many companies keep getting hit..

Not as easy as that, these can be real people with genuine businesses across the other side of the world, which sounds like what happened here. They only have to seem friendly and genuine before asking you to perform a coding test or whatever.

Unfortunately:

1) The dev downloaded it onto a work laptop which was really poor behaviour

2) It sounds like the developer environment was very open instead of segmented. Common but an easy control to use in a high-risk environment.

3) Sounds like a lack of any elevation process e.g. if a developer needed to access a wallet, it very much should sound an alarm/require explicit permission etc.

But it is easy to be wise in hindsight.

It seems in this case really poor behaviour and practices, I can imagine some security engineer shouting I told you so pretty loudly.

On the other end, when doing interviews I suspect 40-50% of candidates use AI assistant tools (might be skewed in tech).

I do miss seeing someone's camera feed break or AI tool break down mid interview.

I think we need to implement a new handshake protocol for job interviews.

Both candidate and recruiter have to call Kim Jong Un a big fat tosser (other swearwords are available) on a recorded video before the interview continues.

It seems like these North Korean IT guys are actually pretty tech savvy and can actually do the job and work -- but they are doing recon at the same time with malicious intentions. An unskilled scammer would get caught every time and couldn't do the work.

I mean it would make sense to hire these NK guys to consult DevSec teams if it wasn't for the travel restrictions in NK -- sort of like how reformed black-hat hackers get legit jobs in the IT sec industry.
