The campaign typically begins with a spear-phishing email containing a link to a cloud storage service (such as Google Drive or Dropbox) where the archive is hosted. 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. ThanksGivingRecipe.7z
A binary file (e.g., data.dat ) containing the final malware. 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: Archive Contents and DLL Side-Loading The
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
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 use of "Thanksgiving" as a lure suggests a specific timing for the campaign, likely aimed at exploiting the distraction of holiday periods or targeting organizations with specific interests in Western diplomatic schedules. This campaign highlights the ongoing shift toward "living off the land" techniques, where attackers leverage trusted binaries to minimize their forensic footprint.
