Researchers used VirusTotal tools and APIs like search, VirusTotal Graph, and Retrohunt to locate files containing stolen data using this strategy. 

Tomer Bar, director of security research at SafeBreach stated, “It is quite a straightforward technique, which doesn’t require strong understanding in malware. All you need is to choose one of the most common info stealers and read about it o
