Ordinary Users Caught Up in the CuckooLogsPublic Leak, 2,883 Hit

HEROIC analysts identified a stealer log file named "CuckooLogsPublic-20250528" uploaded to a public Telegram channel, tied to a leak date of May 28, 2025. The file contains 2,883 records, each pairing an email address with a plaintext password and the URL of the account it was used on. There is no single company or platform behind this breach, the people caught up in it are ordinary internet users whose devices happened to get infected with credential-stealing malware.

Why This Is Dangerous

Because the malware captured these credentials directly from infected computers, the passwords sit in the file in plaintext with no encryption to slow an attacker down. Anyone who downloads this file can try any of the 2,883 email and password pairs immediately, against the site each one was captured from or any other account where the same password might be reused.

What Was Exposed in the CuckooLogsPublic Leak

• Email addresses
• Plaintext passwords
• URLs of the accounts and services accessed

Why This Matters

A file of 2,883 working login pairs is exactly the kind of data attackers feed into automated credential stuffing tools, testing each combination against email providers, banks, and online retailers. Anyone in this leak who reused a password elsewhere is at risk of account takeover, which can quickly lead to identity theft and financial fraud once an attacker gains control of a victim's email address.

How Stealer Logs Work

A stealer log is produced by information-stealing malware that infects a device through a malicious download, a cracked application, or a phishing link, then quietly copies every password saved in the browser along with the site each one belongs to. Once the malware operator collects enough data, they package it into a log file and upload it, as happened here, to a Telegram channel where anyone can access it, regardless of who the affected users are or what they do for a living.

Check If You Are Affected

Ordinary users are exactly the kind of people caught up in leaks like this one, which makes it worth checking your own exposure. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can confirm whether your credentials appear and change them before anyone else uses them.
