Phishing The Phishers

Filed under: — By Aviran Mordo @ 3:31 pm

Cheapskate fraudsters hoping to run phishing scams for peanuts have themselves been hoodwinked. Security watchers have spotted a free phishing kit containing a hidden backdoor that siphons off stolen credentials from the fraudsters who use the technology.

Script kiddies are unlikely to twig that captured credit card numbers are being shared with the coders who developed the phishing kit, a recurrent group of Moroccan fraudsters calling themselves Mr-Brain.

Mr-Brain’s website offers easy-to-use phishing site code, email templates and other hacking tools. The website offers phishing kits for many of the most common targets including Bank of America, eBay, PayPal and HSBC.

Only a basic knowledge of PHP coding is required to set up the kits, which fraudsters can have up and running in minutes. Trouble is that as well as sending victims’ login credentials to the fraudsters’ chosen email address, the data is also surreptitiously sent to the Mr-Brain crew, Netcraft reports. The techniques used by the coders are quite sophisticated.

“The configuration script exploits the case-sensitivity in PHP variable names to disguise Mr-Brain’s electronic mail address as an unrelated but seemingly essential part of the script, encouraging fraudsters not to alter it,” Netcraft explains. In this way Mr-Brain receives stolen credentials via a Gmail account.
