One day after it disclosed a security vulnerability in a wireless networking product, Cisco Systems Inc. must contend with a new threat

Networking equipment maker Cisco Systems Inc. is warning customers about a security hole in two products used to manage wireless LANs and e-business services in corporate data centres.

New versions of the Netsky e-mail worm are spreading on the Internet and may be the work of a different author than previous editions of that worm, according to antivirus software companies.

A new company hopes to make life a lot harder for malicious hackers, releasing technology that analyzes computer code for security violations and enforces secure coding practices.

The Netsky worm swept the competition for "top virus" in March, taking the first, second and third spots in antivirus company Sophos PLC's ranking for the month.

A new version of the Netsky e-mail worm is programmed to launch a distributed denial of service attack on peer-to-peer (P-to-P) networks, contains a message blaming users for spreading viruses and says that Netsky's authors want to stop hacking and illegal file trading, antivirus software companies warned.

Cisco Systems Inc. during the weekend warned customers about the public release of computer code that exploits multiple security vulnerabilities in Cisco products.

Antivirus software companies are again warning e-mail users about a new version of the popular Bagel virus, which is spreading on the Internet through infected e-mail messages and targeting machines running the Microsoft Corp. Windows operating system.
