RSA researchers uncovered the server infrastructure used in a global Point-of-Sale (PoS) malware operation responsible for the electronic theft of payment card and personal data from several dozen retailers, mostly based in the U.S. Infection activity has also been detected in 10 other countries including Russia, Canada and Australia. While the malware used in the operation is not new, RSA researchers discovered that, beginning October 25th, it had logged track 1 and 2 data of payment cards it had scraped from infected PoS systems.
