The XIII_LOGS Telegram Leak Exposed 9,900 Accounts Across Multiple Countries

HEROIC analysts confirmed a verified stealer log dataset known as XIII_LOGS uploaded by a Telegram User was shared on Telegram in May 2023. The file contained 9,900 records harvested from infected devices across multiple countries, including email addresses, plaintext passwords, and the exact URLs where those credentials were entered. This was not a breach of a single company. The data was pulled directly from real computers by malware operating without the victims' knowledge, then posted publicly to a Telegram channel for anyone to download. The global spread of the infections means the credential pool covers banking, email, and social media accounts in numerous regions simultaneously.

Why This Is Dangerous

Most people beleive that stolen passwords require additional work before they can be used. That is not the case here. Plaintext passwords require no cracking, no decryption, and no guesswork. The moment someone downloads the XIII_LOGS file, they have 9,900 working login combinations ready to test against sites in any country.

The addition of URLs makes this dataset especially valuable to criminals operating internationally. Each URL in the file corresponds directly to the website where a given email and password were used. Attackers do not need to guess which platforms to target or which country the victim is from. The file tells them exactly where to go, eliminating friction and increasing the speed at which accounts can be compromised across borders.

What Was Exposed

• Email Addresses: Primary identifiers tied to accounts across banking, email, social media, and workplace platforms
• Plaintext Passwords: Fully unencrypted credentials captured live from infected devices and ready for immediate use
• URLs: The precise websites where each password was entered, giving attackers a direct map to vulnerable accounts

Why This Matters

With 9,900 email and password pairs now publicly available, the risk for affected individuals is real and immediate regardless of where they live. Credential stuffing tools can test these combinations against major platforms at thousands of attempts per minute. Email inboxes are frequently the first target because a compromised inbox gives attackers access to password reset emails for banking, investment, and e-commerce accounts.

From there, the damage compounds quickly. Attackers can lock out the real account holder, make unauthorised purchases, apply for credit in the victim's name, and sell account access to other criminals. Identity theft stemming from a seperate stealer log infection can take months or years to fully untangle, and many victims do not realise anything is wrong until significant financial harm has already occured.

How Stealer Logs Work

Information stealer malware is typically distributed through pirated software downloads, fake game mods, cracked applications, or phishing email attachments. When a user runs the infected file, the malware activates silently in the background and immediately begins collecting saved browser passwords, cookies, session tokens, and autofill data.

Everything collected is packaged into a structured log file and transmitted to the attacker's server. The malware then often erases itself, leaving minimal traces behind. The resulting log files are sold in underground markets or posted freely to Telegram channels. The name XIII_LOGS suggests this may be part of a series of log packages distributed across multiple regions, with "XIII" indicating a batch or operator designation used by whoever compiled the data. Because these infections happen silently, victims typically have no idea their credentials were captured until they check a breach scanner or receive an account lockout notification.

Check If You Are Affected

HEROIC's free breach scanner searches across more than 400 billion compromised records, including stealer log datasets like XIII_LOGS that were distributed through Telegram. If your email address or password was part of this file or any of thousands of other known breaches, HEROIC will show you exactly what was exposed and what steps to take next.

The scan is free and takes less than a minute. Enter your email at heroic.com to find out whether your credentials have been compromised and how to protect your accounts before an attacker acts on the information.
