Fake Google Chrome Sites Distribute ValleyRAT Malware via DLL Hijacking

The ValleyRAT Malware Campaign

Cybersecurity researchers have identified a dangerous campaign by the threat actor Silver Fox, where fake Google Chrome websites are being used to spread the ValleyRAT trojan. This attack specifically targets high-value positions such as finance, accounting, and sales departments to gain access to sensitive corporate data.

How the Attack Works (DLL Hijacking)

The attack is a classic example of trust exploitation. Here is the step-by-step breakdown:

• The Lure: Users searching for Google Chrome are redirected to malicious "drive-by download" sites that look identical to the official Chrome page.
• The Payload: Instead of the browser, users download a ZIP file containing a "Setup.exe".
• DLL Hijacking: The installer uses a technique called DLL Search Order Hijacking. It sideloads a rogue DLL file (tier0.dll) using legitimate executables like "Douyin.exe" (the Chinese version of TikTok).

Capabilities of ValleyRAT

ValleyRAT is a highly intrusive C++ based trojan designed for total surveillance. It can:

• Monitor and record screen content.
• Log every keystroke (Keylogging).
• Establish persistent access to the host system.
• Download and execute additional malicious binaries from a remote server.
