GSM Based Skimmers

Brian Krebs leads the field in reporting on bank ATM machine skimmers that collect banking credentials from ATM customers and relay them to cyber thieves. This is another outstanding article by Krebs that exposes a little piece of the world of cyber-crime.

Why GSM-Based ATM Skimmers Rule

Earlier this year, KrebsOnSecurity featured a post highlighting the most dangerous aspects of GSM-based ATM skimmers, fraud devices that let thieves steal card data from ATM users and have the purloined digits sent wirelessly via text message to the attacker’s cell phone. In that post, I explained that these mobile skimmers help fraudsters steal card data without having to return to the scene of the crime. But I thought it might be nice to hear the selling points directly from the makers of these GSM-based skimmers.

So, after locating an apparently reliable skimmer seller on an exclusive hacker forum, I chatted him up on instant message and asked for the sales pitch. This GSM skimmer vendor offered a first-hand account of why these cell-phone equipped fraud devices are safer and more efficient than less sophisticated models — that is, for the buyer at least (I have edited his sales pitch only slightly for readability and flow).
