144,295 Users Targeted in the CryptogoL12 Stealer Log Breach

144,295 individual people make up the CryptogoL12 11 stealer log, leaked May 18, 2026. That's not a company or a single service that got breached, it's 144,295 separate users whose personal devices were infected and whose saved logins ended up in this one file.

Why This Is Dangerous

Targeting at this scale doesn't work like a traditional hack aimed at one organization. Each of the 144,295 people here was compromised individually, through their own infected computer, wich means the resulting data spans whatever accounts each person happened to have saved in their browser at the time, banking, email, shopping, social media, all of it potentially mixed together.

What Was Exposed

• 144,295 email addresses tied to specific users
• Corresponding passwords stored in plaintext
• URLs showing which websites each set of credentials unlocks

Why This Matters

A file this large represents a genuinely broad cross-section of everyday internet users rather than customers of one particular company. That breadth is exactly why checking your own exposure matters, this isn't limited to people who signed up for one specific service, it could include almost anyone who had the misfortune of running the wrong file on their computer.

How Stealer Logs Work

Malware campaigns capable of producing a file this large typically spread wide nets, hiding inside cracked software, fake game cheats, or malicious ads that reach large numbers of potential victims at once. Each infected machine quietly reports its saved credentials back to the operator, who compiles every victim into one combined release like CryptogoL12 11.
