A botnet used solely to send junk e-mail promoting penis enlargement products has taken over from the Storm botnet as the most prolific sender of spam, according to security researchers.
The botnet Mega-D -- so named because of the products being offered by the spam it generates -- now accounts for 32 percent of all spam being captured by security firm, Marshal.
"This exceeds the level of spam being generated by the Storm botnet at its height, which was at 21 percent of the total spam we captured," Marshal VP of products Bradley Anstis told ZDNet.com.au. "Storm has now reduced to less than two percent of the spam we're tracking at the moment."
