A cryptojacking campaign has affected over 200,000 routers made by Mikrotik, the Latvian networking company.
A Months-Old Vulnerability Exploited
Security researchers recently mapped a series of cryptomining attacks, which initially attacked a large number of users in Brazil to create a growing mining botnet by infecting compromised devices with malware.
According to reports, the devices targetted for the attack were Mikrotik routers which had an outdated software patch.
In April 2018, the company patched a remote access vulnerability which allowed attackers to remotely gain unauthenticated administrative access to the Mikrotik routers.
