The performance of MikroTik devices can be affected by a crypto-mining virus, due to a vulnerable version of RouterOS or its configuration.
It is important to promptly update software that may have vulnerabilities (CVEs), which hackers can exploit to steal data, install mining malware (cryptojacking - malicious code uses the device's resources to mine cryptocurrency), and gain control over devices.
Notice about a miner virus in RouterOS
Patches fix code errors, enhance stability and performance, and add new features. Ignoring RouterOS updates makes the system vulnerable, which can result in losing control over MikroTik devices.
