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."
Benevolent worms are a perennial suggestion in computer security, and the conclusion is always no no no no.
If only there were a similar piece of malware in direct competition with this particular trojan such that both would attempt to remove the other and successfully do so.
It is interesting how malware is adapting so that not only is it able to spread more quickly to a larger number of machines, but also that it's attempting to increase its lifespan by killing off other malware so that the host may not notice that it's infected. I wonder how long it will be until a particular program updates a virus definition list or something similar to remove all other competing malware programs as they come into existence. Also, how much better will the malware be at quickly patching machines against new zero-day exploits than actual virus scanning and prevention software?
Version 2.0 won't just steal data. It'll make trades. Aside from the obvious theft possibilities, the controller would have the ability to create his very own economic meltdown, in any companies he wished, limited only by the size of his botnet...
