Malicious spam is being spread with the use of fake news headlines claiming president-elect Barack Obama has refused the presidency.
The spam messages contain links to the Waledec botnet, say web security experts from the Marshal8e6 TRACE Labs.
The e-mails use subject lines such as "Amazing News" and contain text suggesting that Obama has abandoned the presidency or no longer wants to be president.

The e-mails provide a simple link to a look-alike Obama campaign website. The site hosts links to downloadable malware presented to the user as legitimate news headlines.
The domains for the fake websites include "greatobama" or "superobama".
"Barak Obama's inauguration is just one day away. Spammers have used social engineering ploys like this time and time again to entice spam recipients into clicking on links without thinking," said Phil Hay, senior threat analyst at the Marshal8e6 TRACE Labs.
The Waledec botnet is new on the scene and widely considered by internet security researchers to be the latest creation of the authors of the Storm botnet, which ceased spamming in September 2008.
Waledec first appeared in December 2008, according to Marshal8e6, and continues the Storm botnet's modus operandi of distributing malware via URL links under the guise of sensational news headlines and fake greeting cards.
