These logs never really stop coming. The 76_Boss2 file, posted to Telegram in September 2023, added another 3,151 records to a pile that keeps growing week after week, each one representing a device that got infected and a person who had no idea.


Why This Is Dangerous

The constant flow of these logs is part of what makes them so dangerous. Security teams can't keep pace with every single file being uploaded and traded across dozens of channels, so many leaks like this one never get widely reported even though the data inside is completely usable by anyone who finds it.


What Was Exposed

  • Email addresses harvested from browser sessions
  • Plaintext passwords tied to those same sessions
  • Endpoint data revealing which sites and services were accessed

Why This Matters

Because so many of these files circulate quietly, the people affected rarely find out through official channels. They only relize something's wrong after unauthorized charges appear or an account gets locked out from someone else logging in first. Waiting for that kind of warning sign is alot riskier than checking proactively.


How Stealer Logs Work

Info-stealer malware typically gets onto a device through a fake download, a cracked application, or a malicious link sent through chat or email. Once it's running, it reads through saved browser credentials and autofill data, then exports everything to the attacker, who eventually turns it into a file just like 76_Boss2.
