Unknown developers published a report on two new malware items capable of introducing dramatic amendments into Bitcoin mining on infected computers. As opposed to their counterparts, those malware programs are made in quite an exquisite way and remain almost invisible to a victim.
Both viruses, being Jellyfish (rootkit) and Demon (keylogger) can operate without launching processes in OS core, thus giving no suspicions to their victim.
The programs use GPU rather than CPU to launch on the infected computer which conceals their operation and enhances computing power. According to the experts, this could empower hidden mining of Bitcoin on infected computers.
Linux-based Jellyfish is a concept project employing LD_PRELOAD technique by Jynx, as well as OpenCL API by Khronos. The malware currently supports AMD and NVIDIA videocards. Keylogger Demon has not been described by the developers in details as yet. They just described it as “proof-of-concept” as provided in a work “You may enter, but cannot conceal: invisible GPU-keylogger”.
