Here's something you may have noticed but didn't really think about: Image spam is disappearing. Junk E-mailers have gone back to good ol' text messages, according to BitDefender, one of many companies that sells PC security software.
A year ago, about 60 percent of spam was hidden in bulky, annoying images. That's dropped to just 3 percent. Text spam has jumped from 20 percent to 70 percent.
Spammers have realized that trying to sneak junk through images just wasn't that efficient. Plain text is winning because of its "simplicity, reduced size, and extreme versatility," said Andra Miloiu, BitDefender spam analyst.
