Hackers were exploited a significant SAP Netwever vulnerability tracked as CVE-2025-31324 to deploy auto-collar Linux Malware at the US-based chemical company.
Cyberspace firm Darktress discovered In an attack during an incident reaction in April 2025, where an investigation revealed that auto-collar malware was evolved to include additional advanced theft strategy.
The Darkatress reports that the attack began on 25 April, but active exploitation two days later, provides an ELF (Linux executable) file on the target machine.
Auto-Kaler Malware was first documented by the Palo Alto Network Unit 42 researchers in February 2025, who exposed its clear nature and difficulty in eradication after one leg on a machine.
The backdor adjusts its behavior based on the user’s privilege level, which runs it, and uses ‘ld.so.preload’ for silent perseverance through shared object injections.
Auto-collectors include capabilities such as arbitrary command execution, file modification, reverse shell for full remote access, proxy traffic forwarding, and dynamic configuration updating. It also has a rootkit module that hides its malicious activities from safety equipment.
Unit 42 could not discover the initial transition vector from the attacks that targeted universities and government organizations in North America and Asia.
According to the latest research by dark, actor of the danger actor behind the auto-color exploits CVE-2025-31324, a significant vulnerability in Netweaver that allows informal attackers to upload malicious binergies to achieve distance code performance (RCE).

SAP fixed the defect in April 2025, while the security firms were reported by Reliance, Onapsis, and Watchtower in view of active exploitation efforts, which ended a few days later.
By May, ransomware actor and Chinese state hackers had joined the exploitation activity, while Mandiants had reported evidence about zero-day exploitation for CVE-2025-31324 at least since mid-March 2025.
In addition to the initial access vector, the Darkist also discovered a new theft measure applied to the latest version of the auto-color.
If the auto-color cannot connect to its hardcoded command-end-control (C2) server, it suppresses its malicious behavior. This applies to sandbox and air-gapped environment, where malware will appear benign for analysts.
“If the C2 server is inaccessible, the auto-color effectively stalls and prevents its complete malicious functionality, appearing benign to analysts,” Darktress explains.
“This behavior prevents reverse engineering efforts from exposing its payload, credential harvesting mechanisms, or firmness techniques.”
It has been added to the top of the existence of the privilege-comprehensive performance argument, the use of a fake logs directory, the use of a fake logs directory, the C2 connection on the TLS, the unique ish for each sample, and the top of the existence of “Kill Switch”, which is already added.
With auto-color now actively exploit CVE-2025-31324, administrators should only work quickly to apply safety updates or mitigations provided in the customer. Sap bulletin,
