Type
Win32 worm

Detection
A virus identity (IDE) file which provides protection is available now from the Latest virus identities section.

Several reports of this worm from the wild.

Description
NOTE: W32/Bagle-J sends itself as a password protected ZIP file that is not detected by this identity. However, when unzipped by the user the worm will be detected by Anti-Virus software at the user's desktop.

W32/Bagle-J is an email worm which sends itself via its own SMTP engine to addresses harvested from your hard disk. The worm searches for files with the extensions WAB, TXT, MSG, HTM, XML, DBX, MDX, EML, NCH, MMF, ODS, CFG, ASP, PHP, PL, ADB, TBB, SHT, UIN and CGI.

The worm copies itself to the Windows system folder as IRUN4.EXE and creates the file IRUN4.EXEOPEN (a copy of the worm in a password protected ZIP format) in the same folder.

W32/Bagle-J adds the value:

ssate.exe = <SYSTEM>\irun4.exe
to the registry key:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run

This means that W32/Bagle-J runs every time you logon to your computer.

W32/Bagle-J opens up a backdoor on port 2745 and listens for connections. If it receives the appropriate command it attempts to download and execute a file. W32/Bagle-J also makes a web connection to a remote URL, thus reporting the location and open port of infected computers.

W32/Bagle-J attempts to terminate several Anti-Virus and security related
processes:

ATUPDATER.EXE

NUPGRADE.EXE
OUTPOST.EXE
AVLTMAIN.EXE

W32/Bagle-J searches the mapped drives for folders containing the string "shar" in the folder name. If such a folder is found, the worm copies itself to the folder using the following filenames:
