Security experts at Microsoft are currently warning of a new variant of the “Sysrv-K” botnet. It attacks Windows and Linux systems to infect other computers and mine cryptocurrencies, among other things.
According to the report, the botnet gains access to PCs via vulnerabilities in apps and databases, for which updates are already available. Among other things, older WordPress plugins are mentioned as a gateway. The new variant is also able to Web server control to take over.
Sysrv-K scans systems, among other things SSH keys, IP addresses and hostnames, to then connect to other systems in the network and install copies of itself. As a result, more and more PCs are infected and the botnet is constantly growing.
Microsoft recommends that all Internet-connected systems have all necessary to install updates. In addition, system administrators should be particularly careful when activating new accesses.
We encountered a new variant of the Sysrv botnet, known for exploiting vulnerabilities in web apps and databases to install coin miners on both Windows and Linux systems. The new variant, which we call Sysrv-K, sports additional exploits and can gain control of web servers.
