A Telegram User Uploaded the RUSSIA CORP Leak, 1,081 Exposed

What HEROIC Analysts Found

Picture a Telegram channel where anyone can drop a file for anyone else to download. On February 22, 2026, someone did exactly that with a stealer log named "RUSSIA CORP-OTHERS-PRO MAILS TEST SAMPLE." HEROIC analysts confirmed the file contains 1,081 records, each pairing an email address with a plaintext password and the URL that login was used on.

Why This Is Dangerous

Within minutes of a file like this being posted, anyone in the channel can download it and start testing the credentials. Because the passwords are stored in plaintext, there is no delay for cracking, the login information is ready to use the moment it is downloaded.

What Was Exposed

• Email addresses
• Plaintext passwords
• Website URLs tied to each login

Why This Matters

Once a file like this circulates, it can be copied and reposted indefinitely. If anyone among the 1,081 affected people reused their password elsewhere, attackers can quickly attempt credential stuffing against their other accounts, from email to banking to shopping.

How Stealer Logs Work

Stealer logs start with malware quietly installed on a victim's device, often through pirated software, a fake update, or a malicious attachment. The malware harvests saved browser passwords and login sessions, then sends them back to the attacker, who compiles the stolen data into a file and uploads it to channels exactly like the one where this sample appeared.
