A major botnet marketing campaign leveraging a brand new variant of the notorious Mirai malware, dubbed Murdoc_Botnet, has been noticed focusing on AVTECH cameras and Huawei HG532 routers, exploiting recognized vulnerabilities to contaminate units and set up an unlimited community for malicious actions.
Recognized by researchers at Qualys, the Murdoc_Botnet marketing campaign makes use of exploits equivalent to CVE-2024-7029 and CVE-2017-17215 to breach units and deploy payloads.
As soon as compromised, units are enrolled within the botnet and are able to executing large-scale distributed denial-of-service (DDoS) assaults.
“[This variant] demonstrates enhanced capabilities, exploiting vulnerabilities to compromise units and set up expansive botnet networks,” Qualys defined.
The safety analysts traced the marketing campaign again to July 2024, figuring out over 1300 energetic IPs concerned in its propagation.
How the Malware Spreads
The malware makes use of shell scripts and ELF binaries to infiltrate methods. Attackers provoke infections by exploiting system vulnerabilities to obtain and execute payloads. These scripts fetch malware information, grant them execution rights and take away traces of the set up course of.
Qualys examined greater than 500 samples, revealing constant an infection mechanisms and targets, primarily IoT units like IP cameras and community routers.
International Attain and Detection
The marketing campaign has had a big affect in Malaysia, Thailand, Mexico and Indonesia.
Qualys reported greater than 100 command-and-control servers coordinating the botnet’s actions. The corporate’s Endpoint Detection and Response (EDR) resolution has efficiently recognized a number of cases of this malware.

To mitigate dangers, Qualys suggested:
-
Monitoring uncommon processes and community actions from untrusted sources
-
Avoiding the execution of unknown shell scripts
-
Maintaining units up to date with the newest firmware and safety patches
Murdoc_Botnet represents an evolution of the Mirai malware household, demonstrating the rising sophistication of IoT-targeted cyber threats. Safety professionals should stay vigilant and make use of the ways above, in addition to superior instruments to defend in opposition to these campaigns.
