Spammers have set a new benchmark for mockery, hijacking PCs inside drug giant Pfizer to send out adverts for the company’s most famous product, Viagra, it has been claimed. According to US botnet tracking company Support Intelligence, a total of 138 IP addresses inside the company’s various networks have had to be blacklisted after being found to be relaying spam. In an interview with Wired, the company reports that it has kept 600 examples of spam emails said to have come from Pfizer-owned computers in the last six months.

Most incredible of all, however, is the fact that some of these emails appear to have been designed to sell the company’s own erectile dysfunction product, Viagra, as well as equivalents from rivals such as Eli Lily. Techworld.com - Pfizer PCs hijacked to send Viagra spam
