Cybersecurity researchers at FortiGuard Labs recently found an unseen infostealer dubbed “ThirdEye” that is mainly crafted to steal several information from the systems that are compromised.

While the stolen data and information that are gathered by this infostealer are used to conduct future cyber-attacks.

FortiGuard clarified that ThirdEye, though not technically advanced, gathers the following data from the compromised systems:-

• BIOS data
• Hardware data
• Scans files
• Scans folders
• Detects processes
• Collects network info
• File list of the user’s desktop
• List of usernames registered to the infected computer
• Number of CPU cores and RAM size

ThirdEye Infostealer Malware

Security experts initiated the investigation upon discovering a Russian-named archive file:- 

• [Табель учета рабочего времени.zip]

The zip contains two suspicious files with double extensions, including an executable disguised as a document titled:- 

• [CMK Правила оформления больничных листов.pdf.exe]

ThirdEye, is a relatively basic info stealer that collects basic system data, and when activated, it sends the data to its C2 server at hxxp://shlalala[.]ru/general/ch3ckState.

Besides this, it lacks additional functionalities and features that are common in other malware.

The ThirdEye infostealer decrypts and utilizes the unique string “3rd_eye” to self-identify to the C2 and another hash value.

Apart from this, “Табель учета рабочего времени.xls.exe” is the name of the second file in the archive that matches the file name of the parent file exactly.

The earliest variant was detected in April 2023, and upon analyzing the samples, it was found that the earliest variant gathered fewer data compared to recent samples, but the info stealer has since evolved with several other capabilities.

ThirdEye Profile

• Affected platforms: Windows
• Impacted parties: Windows Users
• Impact: The information collected can be used for future attacks
• Severity level: Medium

At the moment there is no proof of ThirdEye info stealer usage in attacks, but it gathers valuable data from hacked machines, aiding target selection.

Though it’s crafted to gather data, it could serve as a valuable tool for launching cyberattacks by threat actors.

Moreover, most ThirdEye variants were submitted to a Russian public scanning service, with the latest variant possessing a Russian file name, indicating a potential priority for organizations that speak Russian.
