Analysis Summary
The Oski stealer is a malicious data stealer that was originally discovered in November 2019. This successful data-harvesting tool is spreading throughout North America and China, gathering account passwords, credit card information, and other sensitive data. This form of malware is still one of the most common types of malware employed in cyber-attacks. The dashboard of Oski C2 reveals that Oski’s stealing strategies include utilizing man-in-the-browser (MitB) attacks to extract passwords via hijacking browser processes using DLL injection. According to research, this data thief is spread via fraudulent websites that are opened as a result of a router’s DNS settings being hijacked.
