Enterprise Security Technology Tour

Keynote: Joel Snyder, NW Lab Alliance member and senior partner at Opus One

Unfortunately, network security has become a costly catch-22. Just when the stakes to your enterprise are highest, you’re flooded with waves of security technology that are hard to evaluate fully, integrate properly, or deploy effectively. The typically “safe” response is to over-spend and over-build simply because you’re overwhelmed not just with what to buy, but how to buy, when to buy, and why to buy. Find out what you need to know

at the “Enterprise Security: Failsafe Architecture” event.

Today’s bug patches and security alerts:

Eudora vulnerability

A buffer overflow in the popular Eudora e-mail client could be exploited to run arbitrary code on the affected machine. The overflow can be exploited by embedding a “file://” link of 300 or more characters in a message. For more, go to:

Today’s roundup of virus alerts:

Yet another Sasser worm appears

A new version of the Sasser Internet worm, Sasser-F, appeared on Monday, despite claims by German authorities to have arrested the sole author of that worm on Friday. IDG News Service, 05/11/04.

W32/Agobot-JO – Another Agobot version that uses IRC to give attackers backdoor access to the infected machine and attempts to steal passwords. It also tried to prevent access to anti-virus sites. (Sophos)

W32/Agobot-IJ – Similar to Agobot-JO, this variant also attempts to provide unauthorized access to the infected machine via IRC channels. It also terminates certain anti-virus related applications. (Sophos)

W32/Agobot-QA – Another Agobot version that uses an IRC connection to provide backdoor access to the infected machine. This  version spreads via network shares and potentially e-mail. (Sophos)

W32/Agobot-LI – Same properties as Agobot-QA above with the additional ability to launch denial-of-service attacks against remote sites. (Sophos)

Troj/Adtoda-A – A Trojan that displays a message beginning with “Setup was not able to continue the installation.” After the user clicks “OK” twice, the machine is infected. The machine will freeze and need to be rebooted. (Sophos)

W32/Rbot-I – This virus spreads via weakly protected network shares and uses IRC to allow third party users to gain unauthorized access to the infected machine. The virus also attempts to delete certain network shares on the infected machine. (Sophos)

W32/Wallon-A – An e-mail “worm” that spreads as a fake link that directs users to and attempts to download malware to the target machine. (Sophos)
