DarkGate Malware Exploits Samba File Shares in Short-Lived Campaign

July 12, 2024 at 11:21AM

Palo Alto Networks Unit 42 has uncovered a brief DarkGate malware campaign utilizing Samba file shares to spread infections in North America, Europe, and parts of Asia. DarkGate, an evolved malware-as-a-service offering, can perform remote control, code execution, cryptocurrency mining, and more. The campaign highlights the importance of strong cybersecurity defenses against evolving threats.

From the meeting notes, the key takeaways are:

1. Cybersecurity researchers at Palo Alto Networks Unit 42 have identified a recent DarkGate malware campaign that made use of Samba file shares to spread infections across North America, Europe, and parts of Asia between March and April 2024.

2. DarkGate, originally emerging in 2018, has evolved into a malware-as-a-service (MaaS) offering and has been on the rise since the takedown of the QakBot infrastructure in August 2023. It comes with capabilities for remote control, code execution, cryptocurrency mining, launching reverse shells, and dropping additional payloads.

3. The malware campaign begins with the opening of Microsoft Excel (.xlsx) files, which then prompt targets to click on an embedded “Open” button, leading to the fetching and running of VBS or JavaScript code hosted on Samba file shares.

4. DarkGate is designed to evade analysis by scanning for anti-malware programs, checking CPU information, and identifying the presence of reverse engineering tools, debuggers, or virtualization software.

5. The DarkGate command-and-control (C2) traffic uses unencrypted HTTP requests, with obfuscated data in Base64-encoded text.

6. The researchers stress the importance of robust and proactive cybersecurity defenses in light of the continuous evolution and refinement of DarkGate’s methods of infiltration and resistance to analysis.

These highlights provide a good summary of the noted article on the DarkGate malware campaign and its implications.
