XIII_LOGS: 8,685 U.S. Stealer Log Credentials Leaked on Telegram

XIII_LOGS: 8,685 U.S. Email and Password Pairs Released on Telegram

XIII — 13 in Roman numerals — gives this stealer log channel a distinctive identity in the Telegram credential market. The XIII_LOGS upload from February 23, 2023 contains 8,685 U.S. email addresses and plaintext passwords, each paired with the target login URL where the credential was captured. Like all stealer logs, the data represents real people whose devices were infected with malware — their credentials silently harvested and packaged for distribution.

Channel Branding and What It Signals

Roman numeral branding creates a sense of exclusivity and mystique — a deliberate choice by the operator to differentiate their channel from the dozens of similarly-named stealer log distributors on Telegram. XIII_LOGS positions itself as a distinct, recognizable brand in a crowded market. For threat actors browsing Telegram for credential sources, a branded channel with a memorable name is easier to follow and return to for future uploads.

The branding strategy doesn't change what's inside the files. The 8,685 individuals in this XIII_LOGS upload have their email addresses, passwords, and login URLs exposed to every subscriber of that Telegram channel — regardless of what the operator chooses to call their service. The victms had no say in the naming convention.

Three Years in Circulation

Files uploaded to Telegram in February 2023 have been in active circulation for over three years. During that time, the XIII_LOGS file has been downloaded by channel subscribers, potentially reshared on secondary channels, and possibly incorporated into larger compiled breach databases. Each time a file is repackaged into a new compilation, the original victims' credentials reach a new audience — extending the active attack window indefinitely.

Individuals in this file who haven't changed their passwords since February 2023 remain at elevated risk. The credential stuffing tools that use these files don't expire. Automated login attempts against the target URLs in the XIII_LOGS data may still be running today, silently testing each email and password combination against the services where they were originally captured.
