The new cryptographic malware that affects Linux computers, removes other malicious software programs and then connects to your systems.
Trend Micro has discovered a new variety of malware in Linux. This type of malware “selfish” it is responsible for eliminating other malware and cryptocurrency mining programs to be able to use the victim's resources for its own benefit.
The company's researchers discovered this malware after performing a routine check. This happened after viewing a script in one of their honeypots that downloaded a binary from a specific domain. That binary in question is a version of mining software called XMR-Stak. They also mentioned that different fragments of the code resemble features of Xbash and KORKERDS.
The malware also uses Crontabs to survive reboots and deletions.
El método que utilizan los sistemas de detección de malware antiguos para detectar si están infectados ya han quedado desfasados, en cambio los de última generación analizan el uso de la CPU y de la GPU, ya que estos son los elementos más usados para las actividades de minería, y encaso de que se este abusando de estos elementos, investiga los procesos que están requiriendo ese uso elevado de las unidades de procesamiento.
