A previously undocumented Windows-based information stealer called ThirdEye has been discovered in the wild with capabilities to harvest sensitive data from infected hosts.
Fortinet FortiGuard Labs, which made the discovery, said it found the malware in an executable that masqueraded as a PDF file with a Russian name “CMK Правила оформления больничных листов.pdf.exe,” which translates to “CMK Rules for issuing sick leaves.pdf.exe.”
The arrival vector for the malware is presently unknown, although the nature of the lure points to it being used in a phishing campaign. The very first ThirdEye sample was uploaded to VirusTotal on April 4, 2023, with relatively fewer features.
