6,771 Plaintext Passwords From the XIII_LOGS Dump Just Surfaced on Telegram

XIII_LOGS: 6,771 Stolen Credentials From Infected Devices Shared on Telegram

HEROIC analysts identified the XIII_LOGS stealer log dataset, uploaded to Telegram in May 2023 and containing 6,771 records harvested from compromised devices. The data includes email addresses, plaintext passwords, and endpoint URLs collected by infostealer malware without the victims' knowledge. XIII_LOGS is consistent with a class of credential theft operations that use Telegram as a free distribution channel, bypassing the need for dark web infrastructure and making the stolen data instantly accessible to any threat actor who joins the channel.

Why This Data Is Dangerous

The combination of email address, plaintext password, and URL in a single record gives an attacker a complete attack package. They know who the victim is, what their password is, and exactly where to use it. There is no additional preparation required. Attackers routinely feed these logs into credential stuffing tools that can test thousands of login combinations per minute across major platforms. Even if a victim changed one password, any other accounts where the same password was reused remain at risk and attackers definately test for password reuse across multiple sites.

What Was Exposed

The XIII_LOGS stealer log contained the following confirmed data types:

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host addresses)

Why This Matters to You

Even though XIII_LOGS was uploaded in 2023, the data it contains is still circulating. Stealer log data does not expire the way a credit card number does when it is cancelled. If your credentials were in this file and you have not changed your passwords since 2023, those credentials may still be valid and actively being tested. The downstream risks include account takeover, identity theft, and financial fraud. This is not a historical incident to be noted and ignored; it is an ongoing exposure that requires action.

How Stealer Log Breaches Work

The XIII_LOGS file was produced by infostealer malware, a type of malicious software designed specifically to harvest login credentials. The malware gains a foothold on a victim's device through phishing emails, fake software installers, or malicious browser extensions. Once installed, it silently extracts all saved passwords from web browsers, logs new credentials as they are typed, and captures the URLs associated with each login. This data is transmitted to the attacker and compiled into log files like XIII_LOGS. These files are then distributed through Telegram channels where they can be freely downloaded by anyone. Victims have no way of knowing this occured unless they actively check for their data in known breach databases.

Check If Your Data Was Exposed

HEROIC's free breach scanner searches more than 400 billion exposed records, including stealer log files like XIII_LOGS. If your email address or password appears in this dataset or any other known breach, HEROIC will notify you immediately. Early detection means early action: update your passwords, enable two-factor authentication, and lock down your accounts before attackers get there first. Run your free scan at HEROIC now.
