An anonymous reader writes "The Register takes a look at spam touting everything from Viagra to phishing sites being sent from Fortune 1000 networks. Oracle was found to have a machine pushing out a PayPal phishing scam, and BestBuy had a system sending thousands of spams a month. The Washington Post's Security Fix blog also is tracking this story, finding stock spam being pumped from ExxonMobile and from American Electric Power, among others. Another machine at IndyMac Bank was the source of spam touting generic prescription drugs. From the story: '...an IT engineer with American Electric Power, said the stock spam came from a bot-infected computer belonging to a contractor at one of its power generator plants.'"
