Sophos, a world leader in protecting businesses against viruses, spyware and spam, today announced that Vanja Svajcer, principal virus researcher at SophosLabs™, will be presenting at the Information Systems Security Association's (ISSA) Annual Security Conference for the UK Chapter on 8 September 2005.

Svajcer will be presenting a paper on how hackers and spammers are creating and exploiting zombie networks in their attempt to distribute malware, blackmail websites, and steal confidential information.

Zombie computers are infected machines that give control to unauthorized and remote users, allowing them to send spam from the computer or to launch Denial-of-Service (DoS) attacks against websites. Last month, media companies around the world were struck by the Zotob worm which attempted to take remote control of Windows 2000 computers. The suspected masterminds behind the worm have been arrested by police in Turkey and Morocco, and are scheduled to appear in court soon.

In July, Sophos announced the availability of Sophos ZombieAlert™, a new alert service that identifies zombie computers on a business's network.

The annual ISSA conference is designed to educate members about a range of security issues, addressing the current and future malware challenges for IT security professionals. Besides Sophos, other speakers come from companies such as Microsoft, Cisco Systems and Sun Microsystems.

Sophos is the ISSA UK Chapter's Platinum sponsor for 2005.
