The Malware That Duped Target Has Been Found
The malicious program used to compromise Target and other companies was part of a widespread operation using a Trojan tool known as Trojan.POSRAM, according to a new report released Thursday about an operation that investigators have dubbed Kaptoxa.
The malware is a memory-scraping tool that grabs card data directly from point-of-sale terminals and stores it on the victim’s own system for later retrieval.
The code is based on a previous malicious tool known as BlackPOS that is believed to have been developed in 2013 in Russia, though the new variant was highly customized to prevent antivirus programs from detecting it, according to iSight Partners and an internal report produced by the U.S. Secret Service and other government agencies investigating the breaches.
