"Usually, junk mail is easy to spot: It comes from sources users don't recognize, it is hawking stuff they're not interested in, or the e-mails just don't look right.
Spam of the future could be sent from the e-mail accounts of friends or colleagues, the Alberta researchers say. The spam could be so sophisticated that messages may contain abbreviations, personal signatures or misspellings that people would expect to see in e-mail from people they know.
Those tricks would make sure people are more apt to visit a Web link or download an attachment, allowing the spammers to peek into hard drives, grab personal data or infect the computer."
Boo to Canadian researchers working on this crap!
