Advertising platforms like Google Ads enable businesses to display advertisements to target audiences to boost traffic and increase sales. Malware distributors abuse the same functionality in a technique known as malvertising, where chosen keywords are hijacked to display malicious ads that lure unsuspecting search engine users into downloading certain types of malware.

The following chart represents how the infection starts:

Infection chain

The infection starts once the user searches for “WinSCP Download” on the Bing search engine. A malicious ad for the WinSCP application is displayed above the organic search results. The ad leads to a suspicious website containing a tutorial on how to use WinSCP for automating file transfer:

FortiGuard Labs recently came across files that look suspicious, even during a cursory review. Our subsequent investigation confirmed that the files are malicious and revealed there is more to them than meets the eye: they are a previously unseen infostealer we have named “ThirdEye”. While this malware is not considered sophisticated, it’s designed to steal various information from compromised machines that can be used as stepping-stones for future attacks.

Prevent ThirdEye Infostealer

The ThirdEye infostealer has relatively simple functionality. It harvests various system information from compromised machines, such as BIOS and hardware data. It also enumerates files and folders, running processes, and network information. Once the malware is executed, it gathers all this data and sends it to its command-and-control (C2) server hosted at (hxxp://shlalala[.]ru/general/ch3ckState). And unlike most other malware, it does nothing else.

One interesting string unique to the ThirdEye infostealer family (from which we derived its name) is "3rd_eye", which it decrypts and uses with another hash value to identify itself to the C2.
