What it detects
This rule detects loading of the model specific register kernel module via modprobe msr, which cryptominer ELF binaries use to write MSR values that boost hashing performance. It is associated with cryptominer ELFs abusing MSR reported by Uptycs. Loading the msr module and writing to it is uncommon on production servers and, combined with mining activity, indicates resource-hijacking malware tuning the CPU.
Reporting behind it
