UK 3.19 Telegram Stealer Log Leak Exposes 28,187 Passwords

In January 2023, a stealer log file labeled "UK 3.19" was uploaded to Telegram by an individual user, exposing 28,187 records pulled from infected devices. The data set included email addresses, plaintext passwords, and the URLs of the websites those credentials were used on, giving anyone who downloads it a ready-made list of working logins.

Why This Stealer Log Leak Is Dangerous

Unlike a hacked database from a single company, a stealer log is a collection of credentials harvested directly from people's own computers by malware. That means the passwords in this leak were captured in plaintext, exactly as the victims typed them, alongside the exact site each login belongs to. There's no guesswork for an attacker. They can open the file and start logging into real accounts immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials belong to

Why This Matters

Because the passwords are stored in plaintext and matched to specific URLs, this data is especially useful for credential stuffing attacks, where automated tools try the same email and password pair across banking, email, and shopping sites. If you reused a password that appears in this log, an attacker doesn't need to guess or crack anything. They can log in directly, take over your accounts, and use them to commit identity theft or financial fraud.

How Stealer Logs Like This One Get Built

Stealer malware infects a device, often through a fake download, cracked software, or a malicious email attachment, and quietly copies saved passwords, browser autofill data, and login sessions. The infected machine sends everything back to the attacker, who bundles it into a log file like this one and sells or shares it, in this case through a Telegram channel. Because the malware captures whatever is saved on the device, a single infection can expose credentials for dozens of unrelated accounts at once.

Check If You Are Affected

The safest move is to find out whether your email or credentials appear in this leak or any other breach on record. HEROIC's free breach scanner checks your information against a database of more than 400 billion breached and leaked records, including stealer logs like this one, so you can see your exposure and take action before someone else uses your data first.
