MS04-011 - Security Update for Microsoft Windows (835732)
Top of page
Technical Analysis
When Win32/Sasser runs on a computer, it copies itself to the %WINDOWS% folder. In most cases, it adds a value to the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. This value causes the worm to start when Windows is started.
Win32/Sasser acts as an FTP server listening on TCP port 5554. For each connection made on this port, the worm sends a copy of itself to that connected host using the file name <random number>_up.exe.
The worm generates random IP addresses using a certain logic and then sends the exploit shell code to these IP addresses on TCP port 445. If the exploit is successful, a command line shell listens on a TCP port of the remote infected machine. To complete the infection, the worm executes a remote shell script that instructs the newly infected machine to connect to the infecting host and download and execute the worm through FTP. The worm records the count of successful infections to a file on the C: drive.
Win32/Sasser also attempts to abort any unexpected system shutdown by calling AbortSystemShutdown every several seconds in a continuous loop.
Later variants of the worm may drop a variant of Netsky worm. Later variants may not infect Windows 2000 because they import IcmpSendEcho from IPHlpAPI.dll, which is not present in Windows 2000.

How to Prevent Infection
Take the following steps to prevent infection from Win32/Sasser:
Enable a firewall on your computer
Install the MS04-011 security update
Use up-to-date antivirus software
Enable a firewall on your computer
Win32/Sasser cannot infect computers running a firewall that blocks traffic on port 445. Use a third-party firewall product or turn on the Microsoft® Windows® XP Internet Connection Firewall.
