"KEZAAM! SecuryTeam Order" e-mails and malicious web site
25 October 2005
===========================================================================
AusCERT Alert Summary
---------------------
Product: Windows
Impact: Access Confidential Data
Execute Arbitrary Code/Commands
Access: Remote/Unauthenticated
Overview:
AusCERT has become aware of fraudulent e-mails circulating widely to
Australian recipients. The e-mails entice users to visit one several
malicious web sites, which in turn point back to:
http: // friendsoftheenemy.net
This web site contains several browser-based exploits to facilitate the
downloading of malware. The Trojan then attempts to install a keylogger to
facilitate the capture of secure credentials.
Mitigation:
This exploit requires user interaction - deleting these e-mails as they
arrive and not clicking on any links they contain is a safe mitigation
strategy.
Ensuring your computer is up to date with the latest windows patches,
particularly those fixing vulnerabilities in Internet Explorer. Also,
allowing scripts to execute from trusted sites only will offer protection
against exploitation by this web site.
The exploits on this site specifically target Internet Explorer, so using
an alternate browser will also offer protection against exploitation by
this web site.
Updated antivirus signatures may allow detection of this threat. AusCERT
recommends regular updating of virus definitions to ensure the maximum
level of protection available from such threats.
