According to a new report, over 400,000 routers have been infected by a cryptojacking malware that specifically targets MikroTik routers.The attack, which was discovered in August, continues to spread. At the time, approximately 200,000 routers were found to have been compromised by hackers. The figures were based on the number of IP addresses that ran the infected crypto-mining script.Speaking to Hard Fork, researcher VriesHD stated that actual figures could be between 350,000 and 400,000. He also noted that most MikroTik router malware attacks were spread by Internet Service Providers (ISPs) to unsuspecting users.According to VriesHD, the problem could easily be resolved by updating router firmware. However, some routers don’t have this feature enabled. In this case, ISPs could force firmware updates.According to the security researcher, ISPs that have released a patch have been able to overcome the issue. Those that haven’t continue to expose clients to attacks. Most infections are said to have occurred in Brazil.Just a few days ago, McAfee published another report announcing the discovery of a new hard-to-track crypto mining malware dubbed WebCobra.
