Click-Fraud Trojan Politely Updates Flash On Compromised Computers
jfruh writes: Kotver is in many ways a typical clickfraud trojan: it hijacks the user's browser process to create false clicks on banner ads, defrauding advertisers and ad networks. But one aspect of it is unusual: it updates the victim's installation of Flash to the most recent version, ensuring that similar malware can't get in.
Bah, tinfoil hat defense ... uninstall Flash on the premise it's full of security holes and is waste of time.
It always has been.
I don't trust most sites to set cookies or run Javascript ... run Flash?
No fucking way.

Not just "similar" malware, but anything that has a patched-to-date Flash infection vector. It might actually slow the spread of malware, while decreasing its own ability to spread, at least by that mechanism. And finally, when it's found and purged, the infected systems are somewhat more secure.
Not saying this is a good idea, but it seems that if it spread enough, it could decrease infectable targets in the short-term, maybe drastically?
I'm not sure how to feel about this. On the one hand, yes, trojans are bad. But on the other hand, anything that negatively impacts advertisers can't be all that bad.
JailBreakMe.com did a similar thing on iPhones: patched the tiff library exploit that it used to get on the phones in the first place, making it impossible to re-exploit.
I did the same thing with the Commodore Amiga in 1985, modifying a boot virus to include a payload that would patch the MOVE from processor SR. This let me install a 68010, which let me run SVR3 on the thing, without breaking a lot of popular software like Magic Sack and Transformer, both of which used the privileged version of the instruction for no good reason.
