Cybercriminals, looking for ways to exploit the Log4Shell vulnerability, are attacking products from SolarWinds and ZyXEL that are known to have used the Log4j library. Microsoft has recently made a new revelation on the matter by highlighting a zero-day flaw in the SolarWinds Serv-U file-sharing server. On the other hand, Akamai has identified a variant of the Mirai botnet going after Zyxel networking devices to launch DDoS attacks. Applying required patches and ensuring the right security postures through the streamlined combination of people, processes, and technologies can help prevent organizations from such attacks.
A third new bootkit, dubbed MoonBounce, has been discovered in the wild. The malicious impact hides in a computer’s Unified Extensible Firmware Interface (UEFI) firmware, making it hard for proprietary security products to spot. The bootkit is being used by the APT41 threat actor group in targeted attacks.
