SentinelOne Demo: SentinelOne VS Skidmap Linux Cryptominer – Detection

In this video demonstration, we show the SentinelOne Singularity Cloud Workload Security react in Protect mode to detect and respond to the latest Skidmap variation.

Skidmap (MITRE ATT&CK ID: S0468) is a Linux-based kernel-mode rootkit, first observed in 2019 and used in cryptomining attacks. The malware is known for its ability to rapidly embrace new methods to load its kernel modules in stealth and undetected. Skidmap employs shell scripts to modify local cron jobs. These jobs are responsible for collecting and launching, at the attacker’s determined frequency, when the cryptominer will be downloaded and launched. Some variants of SkidMap also contain backdoor features via the authorized_keys file (MITRE ATT&CK ID: T1098.004), which gives attackers an extra advantage when it comes to persistence.

The SentinelOne Singularity platform can identify and stop any malicious activities and items related to Skidmap Linux cryptominer and return systems to their original state.
