By using legitimate cloud services, the attackers increase the likelihood that the download will not be flagged by automated security filters. 2. Archive Contents and DLL Side-Loading The .7z archive usually contains three core components:
Often a signed application, such as a component of Adobe or a security tool, which is used to gain trust from the operating system.
A binary file (e.g., data.dat ) containing the final malware. ThanksGivingRecipe.7z
Capturing user credentials and sensitive communications.
The deployment of this file follows a multi-stage infection chain designed to bypass traditional security perimeters and establish a persistent foothold on the target network. 1. Initial Access and Delivery The campaign typically begins with a spear-phishing email
Once loaded, the malicious DLL decrypts and executes the hidden payload in memory. In the "ThanksGivingRecipe.7z" campaign, this payload is typically , a sophisticated Remote Access Trojan (RAT). PlugX provides the attackers with extensive capabilities, including:
When the user runs the legitimate executable, it automatically searches for and loads the malicious DLL found in the same folder—a technique known as . 3. The PlugX Malware Payload Archive Contents and DLL Side-Loading The
