Linode Compromised; Bitcoins Stolen

Linode Compromised; Bitcoins Stolen

AldryicAldryic Member
edited March 2012 in General

And this is why complete anonymity will bite you in the ass :P

Somebody hacked my backup machine with pool data hosted on Linode and steal 3094 BTC ("hot" coins ready for payouts). Cold backup was not affected in any way by this hack.

It looks that also user database has been compromised. Although passwords are stored in SHA1 with salt, I strongly recommend to change your password on the pool immediately.

Robery of Bitcoins has no impact to pool users, I'm covering the loss from my own income (although it means that many months of my work is wasted Roll Eyes ).

    This is also a prime example of just how much access your host has over your VMs. Choose your providers carefully, folks.

    You never quit, do you ? This is what control freaks cant stop anyway: http://www.usatoday.com/money/perfi/credit/2009-01-21-visa-mastercard-credit-security-breach_N.htm http://blogs.computerworld.com/node/4405 One from major payment systems, one from an individual, some random search for 2 seconds which yielded some million hits. Good luck using VISA/EUROPAY/PayPal... One day the boogie man will run with your money and pay some child porn site. I hope they are very kind with child molesters in the jail, or at least they will believe your story... Besides, you can be mugged in the street, good luck tracing your 1$ bill series. Or you dont use cash also since it can be used in crime rings ? Besides, who doesnt keep data in an encrypted container, mounted remotely only, deserves that fate. Also, using encrypted communication, etc. M

  • @Maounique said: You never quit, do you ?

    No, I'm merely pointing out that had this been PayPal, 1) it would be MUCH easier to trace the offender, and 2) there's a pretty good chance the guy would've gotten his cash back.

    Get off your high horse, kid.

  • Our investigation has revealed a customer support interface was used to access your account Well that sucks, clearly Linode will have to repay the 12k€ in loss.

    But why wouldn't some support guy in India that gets paid 1€ an hour or so just take the 12k€?

    Accountability, I guess. If you hire third-party support (from a reputable company, anyways) you're at least going to have records of who's doing what, unlike an outside compromise.

    That's why I love small VPS providers: if something like this happens you know whom you have to introduce with your crowbar in a dark alley, you can't do that with unnamed "compromised credentials".

    We appreciate your business and certainly want to keep you as a happy and satisfied customer. If there is anything we can do to make this up to you, certainly let us know.

    You just lost 12k due to our incapability, but hey, we'll give you a free month and it's all good.

  • I'm surprised Linode hasn't made a public statement about this yet...

  • This is pretty recent; they're probably still in the 'oh shit' phase of planning just how to announce it.

    I was just looking at purchasing a Linode, maybe I'll hold off for a while longer.

  • Here's my guess... It was an employee (ex-employee) who specifically targeted servers running bitcoind. Linode will make a long blog post, stating they screwed up and will be changing the way the backend works and who has access to it. They will refund this guy for his lost bitcoins (or they will wish they did after the backlash).

  • I'm curious, is stealing bitcoins really as easy as just getting the private key from the server? That seems like a pretty sloppy way to handle that much money.

    3094 BTC = $15314 USD, IF you can figure out how to actually get it as USD.

    I actually have a Linode, but I use it to host podcasts, nothing mission critical.

    @Aldryic "This is also a prime example of just how much access your host has over your VMs. Choose your providers carefully, folks."

    Actually, this is a good example of why the only reliable hosting is self-hosting, as Eben Moglen has been pointing out for 2 years now:

    hxxp://www.youtube.com/watch?v=QOEMv0S8AcA

    hxxp://www.youtube.com/watch?v=9bDDUyJSQ9s

    (Edit: I didn't know that would actually embed. Sorry.)

    The "cloud", or "putting your data in someone else's hands", is fundamentally insecure.

    The home is the last place in civilized society that still requires a warrant, so it's the best legally protected place to host data, and potentially the most technically secure and private, given a competent admin (nobody else gets to see your logs).

    The only problem with that is the terrible uplink for high bandwidth sites. In other words, we need fiber to the home.

    (BTW, the Diaspora social network was inspired by the first talk, since the devs were sitting in the audience.)

  • DerekDerek Member

    Man, that is horrible. Really sad to hear.

  • "All activity by the intruder was limited to a total of eight customers, all of which had references to "bitcoin"."

    I called it. Now, do they refund the idiot who thought it was a good idea to keep $12k worth of bitcoins on a $20/month vps or do they deal with the backlash that will follow if they don't?

    @BuzzPoet said: Actually, this is a good example of why the only reliable hosting is self-hosting

    Exactly. Nobody should be setting up a server with $12k worth of data on a vps, anywhere.

  • So, I don't get it. Linode was the culprit? A worker on Linode? Or just a security bug in their panel?

  • @yomero said: So, I don't get it. Linode was the culprit? A worker on Linode? Or just a security bug in their panel?

    They haven't said, but I would assume it was an employee. And if it was an employee, they should easily be able to track down who did it and repay this guy. If it was not an employee, it will most likely mean they guy is out $12k and Linode's panel has an exploit in the wild.

    Or one of their employees didn't have secure enough information? Maybe got a keylogger on his computer, a lot of possibilities.

  • So, dedicated servers FTW?

    And, how Linode let you run this ultra cpu abusive Bitcoin stuff?

  • They aren't.

    All of the bitcoin stuff is just the 'banks', so it's just a simple PHP website that stores the hashes.

    @ yomero

    I don't see how dedicated servers would be any different.

    You can just hookup a monitor and keyboard......change a few things in the startup lines and change the root password, then get full access to the machine easily.

    @BuzzPoet

    That also has security issues. A "friend" could come over and tamper with it. OR someone could just break into your house and steal the whole darn box.

    Ahm yes, but is more obvious. The datacenters are secure environments. They have cameras, controlled access, etc. Also, if you cypher your hard disks there is no way to retrieve the info.

    @Francisco said: All of the bitcoin stuff is just the 'banks', so it's just a simple PHP website that stores the hashes.

    So, this bitcoin stuff isn't the same as the bitcoin mining, right?

  • So, a little offtopic... can we use Raspberry Pi to calculate hashes and make bitcoins?

  • debugdebug Member

    @yomero said: So, this bitcoin stuff isn't the same as the bitcoin mining, right?

    From what I read, their just storing the wallets (which is the cash). They don't do the mining on the servers.

    Hello, World.

  • BTW, the talk at the water cooler is that a Linode employee did it. That's why the status update mentioned "credentials" being revoked. A hacker has no credentials, and certainly none that would apply to 8 independent clients. No technical security in the world can stop an evil admin, which is why, once again, no mission critical data should be left in the hands of someone else.

    If it's that critical, you either host it on your own property, or you buy your own hardware and physically secure it against tampering before you ever ship it to the data center. Putting $15K on a VPS was just dumb. Doesn't matter who the host is.

  • @BuzzPoet said: That's why the status update mentioned "credentials" being revoked. A hacker has no credentials, and certainly none that would apply to 8 independent clients.

    Unless a Linode staffer, or the active account of a former staffer, had a weak/reused password. For instance... let's say you're using the same password here and on some other 3rd party forum. Say the admin of said forum isn't very honest, and is storing passwords in plaintext for the purpose of social mining. He suddenly has your password to both accounts. It could be a similar situation with Linode... especially if their admins can request pass resets. It's no good simply changing a password if someone has access to the email account tied to that admin login, they can just reset and get the new pass.

  • It has now been confirmed that multiple containers were exploited and over $250k in bitcoins were stolen.

    On a side note, people put over $250k worth of ANYTHING on a vps. LMAO.

  • @subigo said: On a side note, people put over $250k worth of ANYTHING on a vps. LMAO.

    Well, not on A VPS, but on MANY VPSs. They add up, but nobody store 250 k on same container. It was a big exploit, many customers compromised at Linode, they will have a lot of trouble washing the eggs off their face. M

  • @Maounique said: Well, not on A VPS, but on MANY VPSs. They add up, but nobody store 250 k on same container.

    Wrong... one of them had almost $200k.

  • fanfan Member

    I've been mining for a short period and the result was: 1 PTC each 3 to 5 days, not even worth the cost to run a computer fulltime. :-D

    Anyway both sides hold responsibility for this disaster, Linode can fix their system but the PTC's are gone, and not coming back.

    Get off your high horse, kid.

    To make the comparison correct, it means the guy store his paypal credentials unencrypted in the vps. 1. Cool, so PayPal would have known how the data was compromised, who the user behind the open anonymous proxies, botnets, VPS/VPNs bought with fake CC/PayPal, open wi-fi or WEP ones, hacked sites, whatever, was. Linode, on the other hand, knows who did it. 2. Sure, PayPal gives the money back to anyone which has his account data compromised, especially when we deal with hundreds of thousands. On the other hand, Linode, which accepted responsibility from what I know, has some chance to do that.

    [@vedran said] If Linode can screw up this badly, imagine how your $1/m VPS is secure.

    Well, depends who the host is, some ppl here never make mistakes. They forbid all kinds of services to make it sure, except static pages hosted on bullet-proof web servers, such as boa, since apache2 is not exactly known to be flawless. They also inspect the content 24/7 to make sure every data there is legally owned and legal to be displayed so the hardware will never be seized by the cops during some investigation. M

    This is exactly why I don't sign up with the jack and jill hosting companies. I like signing up to hosts which are registered business, been in business a while, if it's a one man company fine but I want to know the person name and somewhat know they're real and reputable.

    Also by choosing providers who own their servers, it shows they're commited.

  • @liam said: Also by choosing providers who own their servers, it shows they're commited.

    Yes, but Linode does own their servers, while most LEB ppl dont, including those that bragg around here. They still failed and anyone can fail, even VeriSign issued fake Microsoft certificates, there are hundreds of failure cases for the most reputable companies. Nobody can be safe out there, no matter the precautions taken, if we try to be 100% safe we dont host even on home computers. M
