More worrying MD5 discoveries

After the recent news about manufactured MD5 checksum collisions, 20 minutes worth of research was carried out to see if any new information could be gathered.

Astonishingly, it turned out that malware can provide an indication of their functionality from their MD5!

For instance:

A downloading Trojan (Mal/TinyDL-H) provides possible evidence of how it is distributed!

A password stealing Trojan detected as Mal/Generic-A details how it wants access!

Mal/EncPk-BN is ready for battle!

A replicant of the virus W32/Sality-AD shows its true nature!

Troj/PSW-Gen shows extreme awareness about its construction!

Troj/NoGot-Gen goads security professionals into a cryptographic challenge!

Troj/Dorf-W thinks it has got everyone fooled!

It looks like Mal/Zlob-D should stay away from pizza…

After all this bogus research, it seems time to join Mal/Packer in a coffee
