Tigger.A Trojan Quietly Steals Stock Traders' Data

**$tarDu$t** recommends a Washington Post Security Fix blog post dissecting the Tigger.A trojan, which has been keeping a low profile while exploiting the MS08-66 vulnerability to steal data quietly from online stock brokerages and their customers. An estimated quarter million victims have been infected. The trojan uses a key code to extract its rootkit on host systems that is almost identical to the key used by the Srizbi botnet. The rootkit loads even in Safe Mode. "Among the unusually short list of institutions specifically targeted by Tigger are E-Trade, ING Direct ShareBuilder, Vanguard, Options XPress, TD Ameritrade, and Scottrade. ... Tigger removes a long list of other malicious software titles, including the malware most commonly associated with Antivirus 2009 and other rogue security software titles ... this is most likely done because the in-your-face 'hey, your-computer-is-infected-go-buy-our-software!' type alerts generated by such programs just might ... lead to all invaders getting booted from the host PC."

      No. It should be assumed this person has familiarity with those systems, in order to develop the code. Acting alone (highly probable), that means he likely has/had accounts with many if not all of those financial service providers. That grossly limits the number of available suspects. His industry and age also narrow the list even further. That probably leaves perhaps 10k worth of potential suspects in the pool. I'd be guessing, but he probably hopes to convert the stolen accounts stocks to cash, launder it through a third party (paypal perhaps), and then return those assets as stock purchases to avoid taxation, which means you only need the cooperation of a few of those providers and demographic data. Link it with possible terrorism to bypass the usual rules that would prevent a dragnet, and chances are good you find your man. At least, that's how I'd investigate.

      I would imagine the guy who wrote this isn't working alone. Most of these kinds of attacks aren't meant to directly transfer money from the victim's brokerage account to an account controlled by the attacker.

      They use the hijacked accounts to purchase large quantities of a low-volume penny stock. The attacker, or the group he works for, already have a large position in that stock. The huge increase in demand pushes the price for the stock up. This causes all kinds of people to sell--including the attacker. And they make a tidy profit, while the victims are left with a large quantity of over-priced stock.

      The hard part about catching the perpetrators is sifting through the list of all the people who sold the stock at the inflated prices. A bunch of people make money from a scam like this, but only one is the criminal.

      And yet you don't state your qualifications. Well, here's mine: I have been in information technology for eleven years, have done network and system administration at the enterprise level, and have assisted investigators tracking down so-called "hackers". I also have about four years of programming experience, mostly to support the aforementioned. I also have spent a significant portion of my professional time learning digital forensics, taking apart malware kits, and have friends that do skip-tracing professionally (they track people down, and I know people who do civil and criminal). I have also worked on classified government systems (can't say which, obviously), and busted two people on-site who attempted to access information without authorization on those systems (the men with shotguns came and took them away). I do know what to look for, and I have caught people who thought they were so very much smarter than we were. Repeatedly, and sometimes in the flesh.

      You're right, I have no idea who this person or people are. That said, if this guy was working with a herder or someone with access, the vector would have been found by now. It hasn't, which means they're not using an established botnet for deployment. Not only that, but while some of the programmic methods may be similar, that alone shouldn't make an investigator jump to the conclusion the two are in contact with one another. Especially not with the volumes of security research on how these networks operate available to the public. Even slashdot has published links to the aforementioned! All this said, again, you're also right that I don't have a degree in psychology, or criminal profiling, etc. -- I just deal with these people on the front line and I'm going by what my gut and my experience tells me should be there. A real profiler would start with known facts, which I don't have, and have a support team to get definitive answers, which I also don't have.
