Mandiant Consulting and FireEye have discovered a new and previously unseen species of malware being used by a Russian , or Russian - speaking , criminal group they have dubbed FIN1 . The agents used a specific ecosystem of malware that works its way into the lower - level components of a target 's systems and is detected before the target system boots ; this makes it extremely difficult to detect . The malware , which FireEye has christened as " Nemesis " , targets credit card transactions , which it then sends back to its command & control centre . Essentially this type of attack is an APT ( ' advanced persistent threat ' ) that is capable of living and operating within large systems with little chance of escaping .
