Article in the NY Times this morning from Brad Stone (who recently moved to the Times from Newsweek):
You’re not the only one. Spam is back — in e-mail in-boxes and on everyone’s minds. In the last six months, the problem has gotten measurably worse. Worldwide spam volumes have doubled from last year, according to Ironport, a spam filtering firm, and unsolicited junk mail now accounts for more than 9 of every 10 e-mail messages sent over the Internet.
Much of that flood is made up of a nettlesome new breed of junk e-mail called image spam, in which the words of the advertisement are part of a picture, often fooling traditional spam detectors that look for telltale phrases. Image spam increased fourfold from last year and now represents 25 to 45 percent of all junk e-mail, depending on the day, Ironport says.
