PNGPlug Loader Spreads ValleyRAT Malware: Data Safety Tips

Cybersecurity researchers have exposed a chain of cyber attacks focused on Chinese-speaking regions, consisting of Hong Kong, Taiwan, and Mainland China. The assaults contain the delivery of the notorious ValleyRAT malware. They used a complicated loader referred to as PNGPlug, according to a technical report published by Intezer last week.

Let’s know more about it!

How the Malware Operates

The attack chain starts with a phishing page that tricks sufferers into downloading a malicious Microsoft Installer (MSI) package disguised as a valid software program. Once carried out, the installer concurrently deploys a benign application to avoid detection even as secretly extracting an encrypted archive containing the malware payload.

Security researcher Nicole Fishbein explained, “The MSI package uses the Windows Installer’s CustomAction feature, enabling it to execute malicious code, including running an embedded malicious DLL that decrypts the archive (all.zip) using a hardcoded password ‘hello202411’ to extract the core malware components.”

These components include a rogue DLL (“libcef.dll”), a legitimate application (“down.exe”) to mask malicious activity, and two payload files masquerading as PNG images (“aut.png” and “view.png”). The PNGPlug loader then injects the payload files into memory, modifies Windows Registry settings for persistence, and executes ValleyRAT.

What is ValleyRAT?

ValleyRAT: a RAT that has been active since 2023 and can give unauthorised entry to infected devices by attackers. Its modern functions consist of taking screenshots and clearing Windows event logs to cover its tracks.

The campaign has been attributed to a threat group known as Silver Fox, which is linked to another cluster called Void Arachne. Both groups utilize a shared command-and-control (C&C) framework named Winos 4.0.

Sophistication of the Attack

The attacks are exceptional for their target Chinese-speaking populations and their smart use of legitimate software to deliver malware. 

“Equally striking is the attackers’ sophisticated use of legitimate software as a delivery mechanism for malware, seamlessly blending malicious activities with seemingly benign applications,” said Fishbein.

The PNGPlug loader’s modular design adds another layer of threat, allowing it to be customized for multiple campaigns. 

Fishbein noted, “The adaptability of the PNGPlug loader further elevates the threat, as its modular design allows it to be tailored for multiple campaigns.”
