It finally happened to Twitter.

Spammers really ride on the latest trend, and just recently they have turned their attention to micro-blogs such as Twitter. As everyone logs in to Twitter, spammers too, log on to tweet– this time about various weight-loss products/drugs and other tidbits on how to lose weight.

Capitalizing on people’s obsession over the topic of weight, spammers infiltrate users’ accounts to post messages with links connecting to weight-loss drugs. Spam tweets even use TinyURL so that their posts look like the usual harmless tweets, only to redirect victims to spam sites.

According to the Trend Micro Malware Blog, “Hacked Twitter accounts are being used to post messages that promote weight-loss drugs. The messages vary in the stated text, but generally states the same message and are all followed by a link that leads to websites where the drugs are being sold. Searches through Twitter for “$5 acai” yields the posts of users whose accounts were hacked.”
