We uncovered the active exploitation of the Apache ActiveMQ vulnerability CVE-2023-46604 to download and infect Linux systems with the Kinsing malware (also known as h2miner) and cryptocurrency miner.

While monitoring Earth Lusca, we discovered an intriguing, encrypted file on the threat actor's server — a Linux-based malware, which appears to originate from the open-source Windows backdoor Trochilus, which we've dubbed SprySOCKS due to its swift behavior and SOCKS implementation

The Monti ransomware collective has restarted their operations, focusing on institutions in the legal and governmental fields. Simultaneously, a new variant of Monti, based on the Linux platform, has surfaced, demonstrating notable differences from its previous Linux-based versions

We observed the threat actor group known as “8220 Gang” employing new strategies for their respective campaigns, including exploits for the Linux utility “lwp-download” and CVE-2017-3506, an Oracle WebLogic vulnerability.

We detail the update that advanced persistent threat (APT) group Iron Tiger made on the custom malware family SysUpdate. In this version, we also found components that enable the malware to compromise Linux systems.

Ransomware actors have been observed to expand their targets by increasingly developing Linux-based versions. Royal ransomware is following in the same path, a new variant targeting Linux systems emerged and we will provide a technical analysis on this variant in this blog.

We intercepted a cryptocurrency mining attack that incorporated an advanced remote access trojan (RAT) named the CHAOS Remote Administrative Tool.

Through our honeypots and telemetry, we were able to observe instances in which malicious actors abused native Linux tools to launch attacks on Linux environments. In this blog entry, we discuss how these utilities were used and provide recommendations on how to minimize their impact.

We found APT group Iron Tiger's malware compromising chat application Mimi’s servers in a supply chain attack.
