none of that helps against a compromised machine.

Actually, it does.
You may fool an attacker into thinking that he hacked all the layers, while he only hacked top 2 of them.

Maybe we are misunderstanding eachother, but what do you think gets captured by a keylogger running on the *host* where you open a VM in a VM in a VM via a VNC session and you type in a TrueCrypt password, anywhere? Bonus points for guessing the same for what happens if you press PrtScr.

Security by obscurity + surprise element.

Security by self delusion is a new one Smiley Although, noooobody expects Self Delusion! We have two VMs.. no, we have three VMs! Wait, I'll come back in again. ... Chief amongst our surprises are such elements as TrueCrypt, VMs...

Quote from: ShadowOfHarbringer
Also, a possible attacker may not be prepared for task of this level of complexity.

Security by underestimating your opponent is another good one.

I think for half a million an attacker will do push ups, run around the block every morning and wear double D in broad daylight, or alternatively pay 10k to a bunch of people who are quite prepared already.

Quote from: ShadowOfHarbringer
Generally my thinking is that you can create multiple levels of complexity and every one of the makes it more difficult for the attacker to hack you.

A hall of mirrors is so Commodore 64 Smiley The object of security is not complexity, in fact the simpler you can make the more secure, because the less components can contain additional vulnerabilities. This happened: firewalls containing problems which made the machine less secure than without them. Virus scanners that kill your data due to false positives etc.

Some moron just admitted to stealing half a million bucks on Twitter?! Time to call your local FBI office.

agreed. theft of $500,000 in assets is a huge deal. you wouldn't get that from holding up a moderately sized bank. this has gotten a fair amount of attention and someone is going to jail for it for a long time. doesn't even matter if its the right person. nothing scares the people in power more then the concept of their money being stolen.

I'm going to get in touch with the RCMP who I hope will co-ordinate with FBI, InterPol and all the other international police agencies that can get involved.

allinvain, I am not sure if this question was asked yet (I skimmed through this thread) but did you use anti-virus software?

Yes, I used Symantec Antivirus and I regularly ran malwarebytes, spybot, bitdefender online scan, f-secure online scan, and eset online scan. I was behind a router's hardware firewall with only a few needed ports open.

You know what guys, if we expect the average joe to have to learn to become a security expert just to use bitcoin, then bitcoin is pretty much doomed. If not it will just remain an anarchistic/libertarian geek's version of paypal. Or it could just piss off the government who will use this as an excuse to go after the exchangers/users because of claims that stolen bitcoin funds could be used to fund terrorism.



All this proves is there is a market for a layer on top of Bitcoin to provide security without the "average joe" having to make any effort. Thankfully, those who do want to make the effort won't require this layer.

In time, someone will provide a security solution for the "average joe". And they will get rich doing it.

Nonsense.  It just means that those who are good at security will become the new guardians of the realm.  Bitcoin was never really meant to be used at the protocol level by Joe Six Pack.  There will be geeks who write secure wallet systems for android and such that let Joe use bitcoins in daily life as an abstract means to pay with his mobile phone or over the Internet securely.  We don't really want one single client with one security model, because if it has flaws they all willl.  We want a bunch of clients, each doing security in a different way.  The bazzar, not the cathedral.

@Allinvain - Bitcoins are apparently very traceble.  Check this out....

This article has some very interesting information.
http://www.forexyard.com/en/news/Bitcoin-exchanges-offer-anti-money-laundering-aid-2011-06-15T220113Z

"Karpeles [MagicalTux] said Bitcoin transactions were in fact traceable. He said that while the system had been built to be anonymous, it was "really easy to track Bitcoins across the network."

"Donald Norman, the co-founder of a London-based consultancy that serves Bitcoin exchanges, said that a data file existed which reflected the complete history of Bitcoin transactions, so that "the ownership of every single coin is completely known and traceable."


I hope that someone still has this data file and is continually expanding it.

The block chain? Although he's mad if he thinks that ownership can be traced beyond this address has this amount of Bitcoin. Of course, some addresses can be linked to the owners, but certainly not all.

Security by obscurity + surprise element.

It will still happily grab all of your TrueCrypt passwords, your mouse movements, all the fractal windows you have open etc.

Who needs mouse movements when you can connect to a (virtual) machine using  encrypted VNC connection ?
The possibilities are endless. VM is just the beginning of the things you can do.

there have been exploits for detecting and getting out of a VM (exactly because people expect VMs to be safe).

Not all of the exploits work on all kinds of VM's.
Also, a possible attacker may not be prepared for task of this level of complexity.

The only way you can be secure is by using a separate, clean, minimal installation on different hardware from the daily use, net connected machine.

This is certainly the best way, but having a hall of mirrors is also useful when you are only using single machine.
As I said, "the possibilities are endless. VM is just the beginning of things you can do".

Generally my thinking is that you can create multiple levels of complexity and every one of the makes it more difficult for the attacker to hack you.

From now on I'm going to store them on a dedicated bitcoin wallet machine with linux on it
It's a good first step, but it's still putting all your eggs in the same basket. You need to diversify. Even if you want to keep bitcoins as an investment or to promote the system, you need to invest at least one out of each two bitcoins mined into a different portfolio. Be it gold, real estate, remunerated savings account, stocks, venture capitalism, more mining rigs, take your pick. And don't forget to give 10% to charities!  

Or you could just put a majority of your coins onto couple of cheap thumbdrives, encrypt them, and put one in a safety deposit box and another in a bubble wrap envelope with your last will and testament.

Yeah, really.  That's at least as damning as some guy bragging in a bar to the drunk next to him.

Bitcoin - helping to end bankster enslavement.
Your best chance at solving this mystery is to focus on your hacked machine, how it was accessed, any malware that is on it. Mostly it sounds like you didn't secure your machine properly, in which case your chance of fixing this disaster will sadly be very small.

I believe it must have been a virus of some sorts. Yes you are right. I don't think I can do anything at this point. Format and reinstall windows is the best I can do, and from there on not ever use windows for any security sensitive sites/systems.
Don't format your windows compute it's evidence that someone can use to find the perps!  Use vmware conversion program to convert it to a VM so you have all the logs and events.  But if you can keep the HD as they may have only deleted a evidence file and not obliterated it thus you could undelete the file.

MY GOD KEEP THAT HD!

Hi everyone. I am totally devastated today. I just woke up to see a very large chunk of my bitcoin balance gone to the following address:


1KPTdMb6p7H3YCwsyFqrEmKGmsHqe1Q3jg

Transaction date: 6/13/2011 12:52 (EST)


I feel like killing myself now. This get me so f'ing pissed off. If only the wallet file was encrypted on the HD. I do feel like this is my fault somehow for now moving that money to a separate non windows computer. I backed up my wallet.dat file religiously and encrypted it but that does not do me much good when someone or some trojan or something has direct access to my computer somehow.

The transaction sent belongs rightfully to this address: 1J18yk7D353z3gRVcdbS7PV5Q8h5w6oWWG

Block explorer is down so I cannot even see where the funds went.

I tried restoring an earler backup of my wallet but naturally that does not work because the transaction has already been validated.

Needles to say I feel like I have lost faith in bitcoin.

Anyone have any ideas what I can do besides just jump off a bridge?!


Without wanting to start a O/S flame war, this is a clear example why I ran away from windows in 2007 when I got USD 1,200 stolen from my E-Gold account due to an exploit in Internet explorer. Since then, it has been Linux and Mac for me, and have never looked back.

This is also another example as to WHY bitcoins should be treated as paper cash: You wouldn't leave a pile of USD 500,000 in cash laying on your living room. If you have that amount of paper cash, you would either build a suitable vault on your house, or secure your cash off site (ie. a bank security box, etc...), otherwise the first crackhead that brakes into your house owns your cash.

So we can surmise that the thief is at least sympathetic to LulzSec if not directly linked, which would give weight to this guys claims: http://twitter.com/#!/Anonakomis . He is a guy affiliated with LulzSec. On this twitter account, he boasts about being responsible for the theft, and how he has donated a small amount from it to LulzSec.

Fuck, I feel like Poirot.

Ah, the French dude! Tongue

Funny guy too, sending 9.11 BTC Smiley I guess you can apply for that amount at least, though it's little consolation compared to the main sum.

I'm really curious now whether this eminently trackable thing is not just PR toward the man, or is this only supposed to be the case when you have their network sifting resources? If so then Bitcoin is anonymous if users are in trouble but transparent to centralized evil, which is the worst of both worlds.. On the other hand, that would be the best case scenario from a gov perspective, which might help convince them not to squash it. Hmm..

BTW, Twitter already caved in the super injunction case, so it shouldn't be too hard to get more info on that particular user. Although he's probably behind proxies etc. if he's any relation of LulzSec anyway.

Clearly this guy was the one that stole the coins? : http://twitter.com/#!/Anonakomis   

Well...maybe. This guy is also a known attention seeker. He might have seen the thief donate to LulzSec and decided it was a good opportunity to claim responsibility and increase his rep. Or maybe he's telling the truth and it was him.
