Risk: Low
Virus writers have moved on from using Osama bin Laden's "suicide" as a lure to trying the same trick with Arnold Schwarzenegger.
July saw VXers seed multiple Usenet groups with messages saying Osama bin Laden had killed himself, pointing users towards "photographs" illustrating the momentous news. In reality these images offered only the HackarmyTrojan. The Trojan has been around for some months and the Usenet trick gives the aging malware a second lease of life.
Over the third weekend in July, messages using the same template, but referring to the supposed death of California's Governor began appearing all over Usenet. The messages invited users to download a zip file containing a "screensaver" (again contaminated with the Hackarmy Trojan). This malicious code has since been taken offline, but users are still advised to be cautious. More copycats can be expected, as the trick is easy to engineer.
Many within the industry claim that some script kiddie got himself a copy of the "Virus Authoring for Dummies", however this could prove to be an interesting attack vector if correctly implemented.
