A Russian hacker who calls himself “Alexey” is infiltrating insecure
networks and adding security patches to Latvian-made MikroTik routers so
they “can’t be abused by cryptojackers, botnet herders, or other
cyber-criminals,” reports ZDNet.
Alexey claims to have secured over 100,000 MikroTik routers so far. A
security expert told ZDNet that over 420,000 MikroTik routers have been
hijacked to mine cryptocurrency on the sly.
