“This is another example of the increasing trend of automated worm exploitation typically following public exploit release by several days,” says Endler.Īntivirus provider Kaspersky Labs notes the worm was written using the Visual C compiler and is about 15 KB in size.

“Both were automatic worms using a relatively new hole in Windows and causing frequent reboots.”Īfter Microsoft issued its LSASS patch, working exploits appeared almost immediately, lately culminating in the fast-spreading Sasser. “This case resembles the Blaster incident from August 2003,” says Mikko Hypponen, director of antivirus research at F-Secure. So far, at least, hundreds of thousands of machine have been affected worldwide. Sasser has reportedly affected a number of organizations around the world, including American Express in the United States, British Airways in Britain (with flights delayed as a result), 1,200 machines at the European Commission in Brussels, Hong Kong’s government systems, and 1,600 machines in Taiwan’s post office. For example, “.Worm can run on, but not infect, Windows 95/98/Me computers.” Symantec notes previous versions of Windows are immune to all versions of Sasser so far, yet may be carriers, passing some variants on to others.

Affected software includes Windows XP, Windows NT Service Packs 1 (SP1), 2, 3, and 4. Sasser-four variants (A to D) have been found to date-exploits a Microsoft LSASS service vulnerability announced and patched by Microsoft in April 2004. The system will now shut down and restart.” Users with infected computers may experience frequent reboots and crashes, or see the following error message with a 60-second timer: “The system process ‘C:WINDOWSsystem32lasass.exe’ terminated unexpectedly with status code-1073741819. Unlike the Slammer worm which was only memory-resident, Sasser copies itself as a file and runs as a process in the background,” says David Endler, director of Digital Vaccine for intrusion prevention vendor TippingPoint. “Sasser doesn’t require human interaction to spread. “.Worm is a network-aware worm that exploits a known Microsoft vulnerability and spreads by scanning randomly chosen IP addresses on Microsoft systems that have not been patched,” notes Symantec.
