Twishing: Beware of the Latest ID Scam

This tricky combination of Phishing and Twitter Uses Common Scam Techniques to steal your identity.

Every time a new communication method becomes popular, fraudsters look for a new way to commit identity theft. One of the latest popular scams is "twishing."

Twishing is a combination of Twitter and phishing, uses the growing popularity of the microblogging service Twitter.com in an attempt to steal your identity.

Twitter, which limits users to 140-character messages broadcast to the public or directly to "followers" who have chosen to receive the updates, is one of the latest identity fraud schemes because it is growing so quickly in popularity due to the message length limitations.

Fraudsters jump on new communication methods because law enforcement is slow to respond and communications providers often will rush out new technology without thoroughly testing potential security flaws.

Security flaws enable hackers to gain access to accounts, but such thefts require some technical knowledge. It’s much easier to lure someone (the idea of fishing lures gave rise to the term "phishing") to reveal private information than to hack into their account.

The idea of luring someone to reveal private information is nothing new. Famous check scam artist Frank Abagnale, subject of the movie "Catch Me If You Can", used clothing (e.g., dressing like a pilot) to lure people to give him sensitive information. While the movie was based on facts, a fictional television program, "The Rockford Files" also featured the lead character using fake business cards and smooth talk to obtain information.

Twishing works the same way. A short public message like “see what they're saying about you on xyzblog" followed by a link can direct the unwitting Twitter user to a blog that looks like Twitter, but is actually a site operated by the fraudster, who then seeks to gain personal information. Twitter recently changed its look, which will likely deter twishing for at least a while. But fraudsters are always looking for the next scam.

This is very similar to fraudsters who misrepresent themselves as being from a large financial institution while sending out millions of official e-mails trying to trick legitimate account holders into revealing personal account information. While most of these e-mails will go to people who have no banking relationship with the financial institution, the phishing e-mail will reach some legitimate account holders. The e-mail will ask account holders to resend their account information – often with the threat of suspending the account if they don’t.

Some of the telltale signs that a phishing e-mail is a fraud are typos, poor grammar or incomplete information in the phishing message. But the message limitations of Twitter make it easy to overlook such details. Twitter users will use chat and text message abbreviations (e.g., “u" for “you") and grammatical rules are largely ignored. So the hints aren’t as obvious.

However, some of the basic steps to protect one’s identity work to protect against twishing just as they do against phishing:

Don’t provide personal information online

If a message looks suspicious, it probably is

Be cautious in opening “retweeted" items. The last sender may not be aware of the malicious nature of the message.
