Breaking Virus News On February 9th, several antivirus vendors reported the appearance of DoomJuice.A, also known as W32.HLLW.DoomJuice.A, WORM_DoomJuice.A, and Win32/DoomJuice-A. Apparently the work of the author of MyDoom.A, DoomJuice.A spreads by exploiting the backdoor on MyDoom.A infected machines. Once installed on the victims machine, it launches a DoS attack on www.microsoft.com. The worm propagates […]

The new W32/MyDoom.B-mm virus adds another twist to the MyDoom story. In addition to switching the DNS attack to Microsofts web site, it uses a standard mechanism in Microsoft Windows to block a users access to antivirus sites. MyDoom.B overwrites the existing Windows Hosts file, normally empty, with a file that blocks the real addresses […]

A powerful worm virus known variously as W32/Novarg.A, W32/Shimg, W32/Mydoom, or W32/Mimail.R is devastating personal and corporate e-mail systems across the globe. This fast-moving mass mailer Internet worm apparently started spreading on the popular peer-to-peer file-sharing application, Kazaa, and has now moved to e-mail.

Tenacious W32/Sober.c-mm Attacks A New Year is a perfect time to set goals and make resolutions.

August, 2003, will be remembered as the worst malware month to date, with Klez.H, Blaster, Sobig.F and other viruses and […]

While antivirus vendors have reported several new viruses and malicious attackers in the past week, we have not seen any new large scale outbreaks. However, the ghosts of virus past are still with us—Klez, Blaster, Swen, Bugbear, Dumaru, Mimail, and WelchiaNachi all haunt the top ten. According to virus analysts, the WelchiaNachi worm has only […]

Maybe its the holiday season, or end of year letdown, but Microsoft did not release any monthly security bulletins for December. The Redmond-based software giant reported that while its consolidating security update delivery to once a month, it may still release emergency bulletins as needed. While no updates may seem like good news, there is […]

When Microsoft released Office XP, users were suddenly faced with having to “activate” the product in addition to entering a valid product key. That proprietary activation scheme helped Microsoft cut down on piracy, but it raised privacy concerns among users. Much of the fervor eventually died down, however, until late 2002 when Intuit shipped its […]

This summers crop of mass mailing DCOM- and RPC-exploiting worms has made “get the patch” a mantra for most savvy users. However, the latest worm throws that reliable action into the gray area, especially for novice users. Thats because the latest batch of worms are posing as e-mailed fixes from Microsoft. W32/Dumaru (several variants),and W32/Swen.A, […]
