Analysis Summary
Muhstik malware has been around since 2017, and we assume that it is based on a fork of the Mirai code and is currently affecting the cloud by way of several web application exploits. The botnet is monetized via crypto mining and with DDoS attack services. It targets a wide variety of web applications, including WordPress, Drupal, and WebDAV, Oracle’s WebLogic application server, as well an assortment of Internet-of-Things (IoT) and Small Office/Home Office (SOHO) devices. Muhstik uses its botnet to mount sizable distributed denial-of-service (DDoS) attacks, but it will also install several cryptocurrency miners on affected systems.
CVE-2022-0543 – Severity High
Redis could allow a local attacker to execute arbitrary code on the system, caused by a packaging issue leading to a Lua sandbox escape. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
