One of the files is “CMK равила oормлени олнин листов.pdf.exe,” which is an executable rather than a document and is labeled “QMS Rules for issuing sick leave” in English. f6e6d44137cb5fcee20bcde0a162768dadbb84a09cc680732d9e23ccd2e79494 is the file’s SHA2 hash value.

The ThirdEye info stealer has comparatively simpler functionality. It contains a variety of system information based on compromised machines, like BIOS and hardware data. Additionally, it lists ongoing processes, folders and files, and network data. All of this information is gathered by the malware once it has been run, and it then sends it to its command-and-control (C2) server, which is located at (hxxp://shlalala[.]ru/general/ch3ckState).
