Cado Security warns of a cryptojacking campaign targeting misconfigured Apache Hadoop, Confluence, Docker, and Redis instances with unique Golang payloads. Attackers use reverse shells, rootkits, and various scripts to exploit vulnerabilities. The extensive attack demonstrates the variety of techniques used to exploit cloud and Linux services, as well as keeping abreast of reported vulnerabilities.
After reviewing the meeting notes, it is evident that a cryptojacking campaign targeting misconfigured Apache Hadoop, Confluence, Docker, and Redis instances with new and unique malicious payloads has been identified by the cybersecurity firm Cado Security.
The attackers are utilizing Golang payloads to automate discovery and exploitation of vulnerable hosts, employing reverse shells and user-mode rootkits to hide their activities. In Docker attacks, they utilize a command to create a bind mount for the server’s root directory, enabling them to establish a connection to their command-and-control and retrieve a first-stage payload. Additional attacks involve the deployment of shell scripts for delivering XMRig miners, various utilities, and user-mode rootkits.
The Golang payloads enable the attackers to search for Docker images and identify and exploit misconfigured or vulnerable instances exposed to the internet, demonstrating a variety of initial access techniques for cloud and Linux malware developers. The attackers are leveraging their knowledge of web-facing services in cloud environments and reported vulnerabilities to gain a foothold in target environments.
Furthermore, the attackers have exploited a critical remote code execution flaw (CVE-2022-26134) in Confluence servers, further showcasing their strategic and targeted approach.
The campaign’s complexity and the attackers’ investment in understanding and exploiting cloud environments reflect a significant threat to organizations utilizing these services. It is crucial for organizations to address misconfigurations and vulnerabilities in their cloud and Linux environments and stay current on reported security weaknesses to mitigate the risk of such attacks.
Please let me know if you need any further information or analysis of the meeting notes.
