XIII_LOGS Suffers Breach Exposing 6,380 Stealer Records

HEROIC researchers found 6,380 records on February 16, 2023 from XIII_LOGS, a Telegram stealer log channel branded with the Roman numeral for thirteen that specializes in curated credential drops.

Why This Stealer Log Is Dangerous

XIII_LOGS is a smaller, tightly branded Telegram drop, which often signals higher quality per record rather than sheer volume. The 6,380 entries were pulled directly from infected devices, so the passwords are in plaintext and matched to exact login URLs. That makes the drop dangerous out of proportion to its size.

What Was Exposed in XIII_LOGS

• Email addresses
• Plaintext passwords
• Login URLs and API host endpoints
• Browser-captured autofill and cookie data
• Application credentials harvested from infected endpoints

Why This Matters

Stealer log credentials do not age well for the victim. Even years after a 2023 drop, attackers still test the same logins against new services, knowing that many users never rotated the password. Because XIII_LOGS contains the login URL with each credential, the bundle remains a practical credential-stuffing asset long after the initial leak date.

How a Stealer Log Like XIII_LOGS Works

A victim device is infected through a malicious download, phishing email, or compromised browser extension. An infostealer silently scrapes saved logins, session cookies, and autofill data, then uploads the loot to the operator. The operator curates and brands the output, then posts it to channels like XIII_LOGS on Telegram so subscribers can weaponize the credentials.

Check If You Are Affected

HEROIC scans 400B+ exposed records across stealer logs, dark web forums, and paste sites. Run a free scan to see if your email or passwords appear in the XIII_LOGS drop, and rotate any password that has ever been reused elsewhere.
