Ransomware gangs are getting faster at encrypting networks, making it hard for security experts to stop. Now, it has come to light that RansomExx and Babuk Locker ransomware gangs are exploiting vulnerabilities in the VMware ESXi product to take over virtual machines deployed in enterprise environments.

Meanwhile, the return of the TrickBot trojan has raised concerns among security researchers. The newly discovered variant comes with a new component called masrv that can enable threat actors to perform local network reconnaissance.
