Scam, usually aiming to siphon off cash from victims, thrive these days. While scammers have tonnes of means to steal money from their victims, the latest one is an alarming case. The world today has billions of phone owners, making this tiny device a great hotspot for con artists.

The Federal Communications Commission has recently issued a warning about a bizarre phone scam. Done via phone-to-phone calls, this relatively new modus tricks people to subscribe to paid services by asking them an introductory question that would trigger an affirmative response.

How this scam works

Swindlers call potential victims. Right off the bat, the caller will ask the victim with the question: "Can you hear me?" Once the victim says "Yes", that is all the scammer needs to subscribe a person to paid services, which will be an added item to the victim's phone bill.

How cramming is possible

In a blog post, the security company notes that cramming is possible "because phone companies allow the inclusion of third-party services in subscribers' bills. This form of consumer deception committed by malicious groups already happened in 2008.
