What’s trending today in cybersecurity? It’s the new Simps botnet! Attributed to the Keksec group, the botnet borrows its source code from Mirai and Gafgyt botnets and primarily focuses on DDoS attacks. This new discovery adds to the pressure of hardening the security of IoT devices.
That’s not all. A new variant of WastedLocker ransomware distributed via the RIG exploit kit has been identified in a cyberespionage campaign, active since February. The exploit kit was used to exploit two scripting engine vulnerabilities in Internet Explorer.
The MountLocker ransomware gang has also upped its game by using Windows API to spread laterally across victim networks.
