Cyber crooks are capitalizing on influenza fears with torrents of eMail promising "swine flu" news but delivering malware or dubious offers for potency drugs or penis enlargement, AFP reports. An alert posted April 30 at the U.S. Food and Drug Administration also warns that scammers have launched web sites hawking bogus products "that claim to prevent, treat, or cure" the H1N1 flu virus. The FDA said it is "informing offending web sites that they must take prompt action to correct and/or remove promotions of these fraudulent products or face immediate enforcement action." "Zombie" computers infected with a dreaded Conficker virus that became an online scourge this year are among machines being used to spew flu-related spam crafted to trick eMail recipients, according to computer security firm Trend Micro. "The thing making it worse is the misinformation out there about swine flu," Trend Micro threats research manager Jamz Yaneza said. "These guys have picked up on all the fears people have. With all the hysteria of swine flu, some people click on these eMails."
