Today’s roundup of virus alerts:

Phishes and bugs: New worm uses PayPal scam

A new e-mail worm is spreading on the Internet and posing as a message from PayPal, the online payment company, in an effort to harvest credit card numbers and account passwords, leading anti-virus companies warned on Friday. IDG News Service, 11/14/03.

W32/Opaserv-V – A worm that spreads via network shares. It also attempts to download updates to its code from a remote Web site. No word on any permanent damage caused by this virus. (Sophos)

Sinala.A – This Windows virus spreads via e-mail (with an attachment called “ALANIS.EXE”) and peer-to-peer file-sharing networks. It exploits the MHTML vulnerability in Outlook Express. The virus tries to download new code from a remote Web site. (Panda Software)

From the interesting reading department:

Dumb defaults

Our first challenge to all vendors mentioned in this column – and Cisco in particular as the 800-pound network gorilla – is to address the dumb security defaults they ship with their products. There are more than a few instances of these dumb defaults, but for the purpose of our discussion, we’ll point to some of the more egregious examples. Network World, 11/17/03.

ISPs take on DDoS attacks

The largest ISPs are promising new tools by next year that will help predict and better defend against worms and viruses that act like distributed DoS attacks and true distributed DoS strikes. Network World, 11/17/03.

Adoption of IPS increasing, cautiously

Blocking attacks with intrusion-prevention systems rather than simply monitoring for them with intrusion-detection systems is slowly gaining ground inside corporations and government agencies, despite worries about disrupting legitimate traffic. Network World, 11/17/03.

Security experts band together

The Global Council of Chief Security Officers says its purpose will be to help IT security executives in all industries and branches of government boost their effectiveness within their organizations. Network World, 11/17/03.

Breaking the glass firewall

IT women are gravitating to information security, where cross-disciplinary skills are key. Network World, 07/17/03.

Microsoft seeks government, private security alliances

Microsoft is in talks with governments and companies in several countries to establish partnerships to help protect computer users against cyber attacks, it said Friday. IDG News Service, 11/14/03.
