TinyPOS: Handcrafted Malware in Assembly Code

TinyPOS: Handcrafted Malware in Assembly Code (Malware and Vulnerabilities)

Legacy software vulnerabilities have created opportunities for hackers to steal credit card data and other personal information using tiny point of sale (POS) malware, according to research published by Forcepoint. Researchers reportedly analyzed 2,000 samples of POS malware and found that many are handcrafted, written in assembly code and very small; thus, researchers aptly named the malware TinyPOS. Of the samples analyzed, 95% were loaders used to distribute malware to systems. “The most probable initial vector would be a remote hack into the POS system to deliver the Loaders. That attackers are targeting POS systems is nothing new, particularly because they collect large amounts of personal data. Because of their vulnerabilities, Ryan Wilk, VP of customer success for NuData Security, a Mastercard company, said POS systems have long been a prime target for cyber-criminals.
