VERY IMPORTANT

Most point-of-sale (PoS) threats follow a common process: dump, scrape, store, exfiltrate. FastPOS (initially detected by Trend Micro as TSPY_FASTPOS.SMZTDA) was different with the way it removed a middleman and went straight from stealing credit card data to directly exfiltrating them to its command and control (C&C) servers. FastPOS was true to its moniker—pilfer data as fast as possible, as much as it can, even at the expense of stealth. The malware is a reflection of how PoS threats, though no longer novel, are increasingly used against businesses and their customers. As such, FastPOS’s update does not come as a surprise—in time for the oncoming retail season to boot.
