Social-networking sites such as Facebook represent one of the most challenging frontiers for personal privacy.
In recent events, Facebook users had a confusing mix of fake and real malicious treats, and Google launched a beta of its take on social networking.
Facebook photo-tagging exploit can be hazardous
Do cyber hoaxes ever contain a grain of truth? A few months ago, one such hoax went like this: If someone tags you in a Facebook photo and you click on the photo, your PC will be infected with a virus.
While some websites rightfully decried this as a hoax, around that time something less serious, but still annoying, crept onto Facebook.
The exploit went like this: Your Facebook wall indicated you’d been tagged in a friend’s photo. Going to that photo did not result in an infection — but the caption of the photo contained a shortened URL, and if you clicked on it, bad things might happen to your computer.
At the very least, the exploit perpetuated itself by posting specious photos to your friends’ walls — tagging them in the photo. Your friends might then click on the bad link within the caption and infect themselves with malware. They might also perpetrate the exploit onto their friends’ walls, spreading the infection.
