BlackWorm Summary

Over the last week, “BlackWorm” infected more then 700,000 systems as measured using a counter Web site used by the worm to track itself. This worm is different and more serious then other worms for a number of reasons. In particular, it will overwrite a user’s files on February 3rd. ISC Handler’s Diary, 01/24/06.

W32/Sdbot-AOS — A second Sdbot variant that exploits known Windows flaws as it spreads through network shares. It drops “win32ssr.exe” in the Window System folder. (Sophos)

W32/Sdbot-AQH — The third Sdbot Trojan of the day is similar to the previous two, except it places “RpcCenter.exe” in the Windows System folder. (Sophos)

Troj/Mdrop-KZ — A Trojan that seems to just drop useless files on the infected host: “cache.exe” and “brun32.exe”, both in the current folder. (Sophos)

Troj/VB-TC — A virus that steals information by popping up a dialog box claiming to from AOL asking for personal information. It uploads the captured data to a remote site via FTP. It copies itself to the Startup folder as “AOLUpdate.scr”. (Sophos)

W32/Rbot-BSC — A new Rbot variant that spreads through network shares and allows backdoor access via IRC. It installs “snddrv.exe” in the Windows System directory. (Sophos)

W32/Rbot-BKA — The second Rbot variant of the day uses the file “outlook.exe” in the Windows System directory as its infection point. It too allows backdoor access via IRC. (Sophos)

W32/Rbot-BLC — A third new Rbot variant. This one exploits a number of known Windows flaws in its attempt to spread through network shares. It drops “Acrord32.exe” in the Windows System folder. (Sophos)

W32/Feebs-E — An e-mail worm that arrives from a “Protected Message service” and through peer-to-peer networks. It drops “ms.exe” in the Windows System folder as well as “ms32.dll”. The virus pops up an HTML form that tries to collect information from the user. (Sophos)
