Attackers are exploiting a critical remote code execution vulnerability in Apache ActiveMQ to target Linux systems with a cryptocurrency miner. The malware, known as Kinsing, infects vulnerable systems and deploys a cryptocurrency-mining script that drains resources. The flaw, tracked as CVE-2023-46604, allows remote attackers to execute arbitrary commands on affected systems. The Apache Software Foundation has released patches, but threat actors continue to exploit unpatched systems. Security experts urge organizations to implement the patches and maintain up-to-date security measures.
From the meeting notes, here are the key points:
– The Kinsing malware is targeting the Apache ActiveMQ critical remote code execution (RCE) vulnerability to infect vulnerable Linux systems with a cryptocurrency miner.
– The flaw, tracked as CVE-2023-46604, allows remote attackers with access to an ActiveMQ message broker to execute arbitrary commands on affected systems.
– Kinsing is a threat group known for targeting Linux systems to mine cryptocurrency and carry out other malicious activities.
– Kinsing’s attack strategy involves using public exploits to download and execute cryptocurrency miners and malware on vulnerable systems.
– Once infected, Kinsing actively seeks out competing crypto miners and removes them from the infected host.
– Kinsing ensures persistence on the affected host by adding a cronjob to download and execute its malicious bootstrap script every minute.
– Kinsing also loads its rootkit in /etc/ld.so.preload, completing a full system compromise.
– The root cause of the vulnerability is an issue with the validation of throwable class types when OpenWire commands are unmarshalled.
– Organizations using Apache ActiveMQ are advised to patch the flaw and implement security measures to mitigate the risks associated with Kinsing.
