stealer_log (also observed as bot in some indices) represents a record of a compromised device whose credentials and browsing data were harvested by an information stealer malware (such as RedLine, Raccoon, or Vidar).
These entries originate from dark-web marketplaces (for example, “Russian Market”) where attackers sell logs containing cookies, saved passwords, and session tokens from infected machines.
Each document corresponds to a single device or “bot,” with metadata describing where and when it was first seen, its environment (OS, IP, ISP), and the websites and services discovered in its data.
