Hearing from a lot of new friends lately? You know, the ones that write “It’s me, Esmeralda,” and tip you off to an obscure stock that is “poised to explode” or a great deal on prescription drugs.
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. (continued) |

Antispam companies fought the scourge successfully, for a time, with a blend of three filtering strategies. Their software scanned each e-mail and looked at whom the message was coming from, what words it contained and which Web sites it linked to. The new breed of spam — call it Spam 2.0 — poses a serious challenge to each of those three approaches.
Spammers have effectively foiled the first strategy — analyzing the reputation of the sender — by conscripting vast networks of computers belonging to users who unknowingly downloaded viruses and other rogue programs. The infected computers begin sending out spam without the knowledge of their owners. Secure Computing, an antispam company in San Jose, Calif., reports that 250,000 new computers are captured and added to these spam “botnets” each day. |
