    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.
      • ffsm8 4 minutes ago
        I mean sure, but as long as you can deploy directly any permissions models are meaningless for an attacker? They can just be removed.

      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.

          .. backdoors which enabled the dev to deploy exploits of their own which wouldn't be visible through CI?

        TBH CI does not prevent this kind of mistakes. I've seen people triggering the wrong CI pipeline.

      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!

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

      I have saw companies doing social engineering as part of their intrution testing, I imagine fake interviews are (or will become) part of these.
      • Aurornis 1 hour 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).

        • quaffcode 47 minutes ago
          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.
      • thomc 58 minutes 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.
      • shepherdjerred 25 minutes ago
        Is that even legal? Wouldn’t a fake job interview be, in a sense, tricking you into taking time off and working without pay?

        It'll be hard to time a job opening receiving interviews to line up with intrusion tests in a way that people would not be on guard against it in a way not normal.

            Using pentesting to also test employee loyalty is a great way to get the entire company to hate working there.
    • WesolyKubeczek 43 minutes 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.

    Doing ANYTHING on a work issued laptop outside of your role is such a dumb idea for a litany of obvious reasons that I'm genuinely shocked people do it. Let alone participate in interviews for other companies on it.

      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.

              It would never occur to me to use an employer's hardware for such a purpose. It seems absurdly lazy, but I know that not everyone's life works like mine, so I would like to understand why this would be a real problem for people.

              • pcthrowaway 2 minutes ago
                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.

                I had a really bad meeting one day that became the straw that broke the camel's back. When I went back to my desk, I saw an interesting job posting. 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.
          • dylan604 1 hour ago

      Working in a financial institution, I was surprised they could do all this. Our work laptops are so locked down (sometimes maybe too locked down) that we'd never be able to download a random .exe

      I think Binance needs to start having IT Security like a bank as well.

      • cityofdelusion 1 hour 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.
      • GoToRO 1 hour 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.
        • gadders 1 hour ago
          Most banks give you a crippled version of Admin rights via a 3rd party tool. If you need more than that, tough/you're doing it wrong.

          Banks, at least in the U.S., are highly regulated and this would be very abnormal and subject to regulatory non-compliance, especially when the bank crosses into “big bank” territory. This stuff is regularly audited internally and externally.

        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.

        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.

        • pjmlp 1 hour ago

        • sgerenser 1 hour ago
          Yeah, I almost suspect a lot of these cases are BYOD (like the above commenter who said 70% of the Zoom interviews he hosted showed the candidate using their current company's Zoom account). I just can't imagine there are that many people dumb enough to interview on a "work computer" otherwise. In the world of small or less tech savvy companies, BYOD is pretty common.
        • pjmlp 1 hour ago
          Usually BYOD requires IT clearance and installation of the same management software like company devices.

      At several companies I’ve seen folks run torrents to watch movies at work.

      Once I was on a Zoom call, and I noticed music production software on my colleagues computer.

      When I pointed it out, they responded with something like “ Ohh, my kids make music.”

      Neat, I guess.

          SWE's are the worst about security, I swear most are worse than the average person when it comes to security practices.

          "Need some new software" = "Download it from some random website"

          "Software won't run" = "Turn off AV and get it everything permission"

          "Still won't run" = "run as root"

            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.

      Sure, but that's not really going to protect you. Could easily be that you are the interviewer and the interviewee asks you to click on sketchy link, or it could easily just be a call with a fake supplier or sales representative. It maybe makes it a little bit harder, but there's still many ways for social engineering to land something on work computers.

        So despite it being a "company" computer I personally installed the blank SSD and installed Arch on it and did not install any company spyware.

        I was perfectly comfortable also having Steam installed so I could entertain myself on the plane on business trips. I knew everything installed and spyware wasn't on the list.

        While I love the "edgy-ness" of this, I remember doing something like this around 2013 in Manhattan and kind of enjoyed it. They had me go into a room, and gave me a paper with an open ended question: it was something along the lines of, write as much detail as I could about what happens when a user visits a URL in a web browser. E.g. explain as much as I know about TCP, HTTP requests, web servers, etc. I think I touched on how Cookies worked as well.

            Couldn’t get a straight answer as to what team does, what role is for, real day to day I’d be walking.

            Only clear thing was scale of architectural mess stemming from a political mess… and not a lot of interest in changing it.

        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.

          You already have a degree from some university, and you already worked in software development for quite some time. So it's very annoying to do some test over and over again for every job application.

            Yep. Now substitute doctors/lawyers/accountants/civil engineers into the equation and see how you feel about it.

            Surely they don't take a test for every client, but I'd consider the interview process more like a "workaround" for the lack of standardized tests for software engineers instead of the lack of respect.

    With the AI craze going on recently I've worked at multiple companies where an internal AI tool was vibecoded and I've always been worried about the security implications.

    I was #opentowork on LinkedIn and got approached multiple times with fake companies and interviews. LinkedIn is not doing enough to combat this.

    I even create a 1 man company for my consulting services and I receive ads about how people at my company saved me a spot on an online game.

    LinkedIn is partially responsible for their neglect here.

    It is crazy that this Engineer A fell for this malware ad (how do people still fall for these & how does Google still get away with serving malware like that):

    https://isc.sans.edu/diary/32942

    It is kind of weird that they mention it though, if they replaced the devices and rotated credentials? Just to later mention that an "internal AI tool" was used to steal that Engineer As credentials again?

    And also, what are those "obfuscation techniques"? It looks very straight forward, replacing the pyenv, there's nothing much obfuscated in it? Except for putting it in a different folder.

    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.

    Yeah, lots of good conversation on steps to take. One thing I never see mentioned is who should review and test them. Especially for a financial company, it seems they have no IT compliance/audit functions. Even at many big companies it seems IT control creation, maintenance, and testing is largely ignored or just put onto the people implementing and performing the control - a huge conflict of interest. Control analyst posting are something like 1 to 10K when measured against dev postings. Really telling when it comes to what companies actually care about...

    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.

    The way I read the Binance post[0] is that the first mistake was "Engineer A from Wallet DevOps" clicking on a malicious Google ad[1]. If Google didn't provide that attack vector, maybe this wouldn't have happened that time.

    It's getting really confusing with these online job offers, including interviews and assignments. Various people are pretending to be recruiters. I've basically stopped answering phone calls, and everything goes to voicemail unless the caller is in my contacts. But that is hard to do if you are looking for a job. Honestly, if you are the target of this type of campaign, as described in this article, there is probably a good chance you will get compromised, even if you are normally careful.

    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...

    Yes of course they didn't. The whole "endpoint security" industry is a scam. They're attempting to (or attempting to appear to) solve an impossible problem. All they do is install spyware and backdoors, reducing security rather than enhancing it.

  • AlexITC 1 hour ago
    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.

    Founder of Callstrike here .. we build real time deepfake & voice impersonation attack simulation tools for a living so this is literally what I deal with every day.

    The biggest irony is that we get at least a couple of signups every month from South Korea, Russia, India, Nigeria just to try getting access to our platform for running these attacks ..

    Here is the most recent copy paste from a Calendly invite ..

    >Invitee Email: >ashley@cairnsovereign.net

    >Invitee Time Zone: >Central European Time

    >Questions:

    >Please share anything that will help prepare for our meeting.

    >We are an MSP from the UK that is look for a deepfake platform to run campaigns for our clients. We typically use open source software but there is a gap in our portfolio for deepfake testing that we can't fill with our usual open source philosophy.

    The company website https://www.cairnsovereign.net/ was registered just 2 days ago .. they have no linkedin presence, fake CEO and fake CTO and fake everything ..

    I still accepted the invite and joined and the person has a strong northern british accent .. he askd me to let his AI bot join the call to take notes ... i refused .. to which he swore and said that if a meeting bot is not allowed .. then i dont want to talk and abruptly hung up ...

    PS: if anyone wants to see .. this is what a real time voice impersonation call and real time deepfake faceswap .. looks like ..

    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.

  • odyssey7 52 minutes ago
    Where do these people find jobs so secure that they wouldn’t bat an eye at interviewing for another job in a context where their current employer can watch them do so?

    Even if you don’t understand the security concerns of running some 3rd party’s scripts on a work device, more pedestrian situational awareness should have prevented such a wild misjudgment?

I've had plenty of interviews where I was expected to clone, fix, and run a repo, which as far as I can tell, all were from legitimate companies. An illegitimate company could easy do the same process with malware.

    >> trace and freeze the assets

    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.

    The party is ending. The house lights are flashing. Crypto will either become controlled so illegitimate transactions will be roll-back-able (presumably with proper court or NatSec orders), or it will be banned.

    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.

      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.

      • CommanderData 2 hours ago
        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.
