A botnet dubbed Brain Food is giving webmasters indigestion with related attacks that push bogus diet pills and IQ-boosting pills via web pages hosted on legitimate sites. 2,400 of those compromised sites have been active over the past seven days pushing dubious pills under the false premise the product claims made were originally on television shows Shark Tank and Entertainment Today. So far, spammers have been successful, thanks to an effective Hypertext Preprocessor (PHP) script (also called Brain Food) that has adroitly avoided detection on websites hosting pitches.
