Identity Theft Risk: CuckooLogsPublic Leak Exposed 6,053 Passwords

HEROIC analysts found a stealer log file uploaded to a Telegram channel on October 29, 2025, labeled "CuckooLogsPublic-20251029." The file contained 6,053 records pulled directly from infected devices, each one pairing an email address with a plaintext password and a URL pointing to the API host or login page it unlocks. The data was harvested endpoint by endpoint through malware rather than stolen from a single company's servers.

Why This Is Dangerous

Because the passwords in this log are stored in plaintext, an attacker does not need to crack or guess anything. They can pull an email and password pair directly from the file, open the matching URL, and log in immediately as the account owner, using the same identity details tied to that account to open new lines of credit or impersonate the victim elsewhere.

What Was Exposed in the CuckooLogsPublic Stealer Log

• Email addresses
• Plaintext passwords
• URLs of the associated API hosts and login pages

Why This Matters

Once an attacker gets into one account using credentials like these, identity theft becomes a real possibility, especially if the compromised email is also used for password resets on banking or shopping accounts. Attackers use logs like this one for credential stuffing, testing stolen email and password pairs across many different services. Anyone among the 6,053 people in this log who reused a password elsewhere faces genuine risk of account takeover and financial fraud.

How the CuckooLogsPublic Stealer Log Was Created

A stealer log is produced by infostealer malware that infects a device, typically through a fake download, cracked software, or a phishing link. Once running, the malware quietly copies saved browser passwords and autofill data, bundling everything into a single file. That file then circulates on platforms like Telegram, exactly where this CuckooLogsPublic file surfaced, letting anyone who obtains it use the credentials directly without ever needing to breach the services named inside.

Check If You Are Affected

If your email address might be part of the CuckooLogsPublic stealer log or another breach circulating on the dark web, HEROIC's free breach scanner checks it against a database of more than 400 billion leaked records. Run a free scan today, and if your credentials turn up, change the affected passwords right away and stop reusing them across sites.
