The Internet's new hit worm also performs a denial of service attack against The SCO Group's Web site.

The rapidly spreading MyDoom worm (a k a Novarg.A by Symantec Corp. and MiMail.R by Trend Micro Inc.) is poised to perform a denial of service (DOS) attack against The SCO Group Inc.s Web site (www.sco.com). The new worm has many of the standard malware worm behaviors of recent attacks in addition to the DOS attack, and this is not the only recent DOS attack against SCOs Web site. As is shown by performance monitoring of access to the Web site by the British security analysis firm Netcraft Ltd., the recent performance problems at the site may or may not be related to the worm, and we had no trouble getting to the site. MyDoom also opens TCP ports in the range of 3127 to 3198 to create an open proxy server for remote access by attackers.

Read Steven J. Vaughan-Nichols column, "With Friends Like These, Linux Doesnt Need Enemies."
Symantecs analysis of the worm says it "can perform a Denial of Service against www.sco.com using a direct connection to port 80. Creates 64 threads which send GET requests. The DoS is active between February 1, 2004 and February 12, 2004." This indicates that the sporadic attacks so far are indicative of clock errors in some systems, and the real attack is set to begin Sunday.

Unless a defense is in place by then, the attack could be significant. According to Ken Dunham, director of malicious code at iDefense Inc., "MyDoom is spreading at a very high rate, reminiscent of SoBig.F in August of 2003. MyDoom is going to be one of the more notable worms for all of 2004."

SCOs recent legal actions have made many enemies in the open-source community and other areas. The company has come under significant verbal attack, in addition to technical attacks such as this one.



 
 
 
 
Larry Seltzer has been writing software for and English about computers ever since—,much to his own amazement—,he graduated from the University of Pennsylvania in 1983.

He was one of the authors of NPL and NPL-R, fourth-generation languages for microcomputers by the now-defunct DeskTop Software Corporation. (Larry is sad to find absolutely no hits on any of these +products on Google.) His work at Desktop Software included programming the UCSD p-System, a virtual machine-based operating system with portable binaries that pre-dated Java by more than 10 years.

For several years, he wrote corporate software for Mathematica Policy Research (they're still in business!) and Chase Econometrics (not so lucky) before being forcibly thrown into the consulting market. He bummed around the Philadelphia consulting and contract-programming scenes for a year or two before taking a job at NSTL (National Software Testing Labs) developing product tests and managing contract testing for the computer industry, governments and publication.

In 1991 Larry moved to Massachusetts to become Technical Director of PC Week Labs (now eWeek Labs). He moved within Ziff Davis to New York in 1994 to run testing at Windows Sources. In 1995, he became Technical Director for Internet product testing at PC Magazine and stayed there till 1998.

Since then, he has been writing for numerous other publications, including Fortune Small Business, Windows 2000 Magazine (now Windows and .NET Magazine), ZDNet and Sam Whitmore's Media Survey.
