Rustock awakens, spam volume back up
Earlier this month, researchers with Symantec's MessageLabs noted spam volumes had dropped dramatically as Rustock, the largest of the spam botnets, went quiet. Researchers aren't sure why this happened - only that global spam levels dropped massively as a result. Not surprisingly as Rustock is responsible for 88 percent of all global spam.
The quiet period was short lived. It appears Rustock has sprang to life again because levels of spam have increased. MessageLabs Intelligence honeypot servers saw an increase of roughly 98 percent in spam traffic between 00:00 and 10:00 on January 10th compared to the same period on January 9th. More spam is expected.
"While levels of Rustock output appears marginally lower than before Christmas, we see no reason they won't reach those previous levels again, bringing global spam levels back up to the approximately 90 percent levels we had become so used to," Symantec's Marissa Vicario said in a blog post.
