‘Dangerous’ Russian hacking group exploits bugs in Microsoft Windows, Firefox browser: What users should do

A Russian-linked hacking group is reportedly exploiting two newly discovered zero-day vulnerabilities. Security researchers have warned that the Russian cybercrime group known as RomCom has been misusing these security flaws to target Firefox and Windows users in Europe and North America. These “zero-click” exploits, identified by security firm ESET, allowed hackers to remotely install malware without any user interaction. The vulnerabilities were unknown to software makers, giving them no time to develop fixes before attacks began. However, after being notified about the zero-day vulnerabilities, both Microsoft and Mozilla have patched these security flaws. If users haven’t updated their Firefox browser or Windows system should do it right now.
