Analysts Link LulzsecCloudLogs Dump to 1,169 Stolen Credentials

HEROIC analysts have linked a stealer log file named "LulzsecCloudLogs Filtered Cookies," uploaded to a Telegram channel by an anonymous user in December 2023, to 1,169 exposed records made up of email addresses, plaintext passwords, and the URLs of the sites those credentials unlock.

Why the LulzsecCloudLogs Dump Is Dangerous

Stealer logs are pulled directly off an infected computer rather than stolen from one company's database. Malware on the victim's machine reads every password saved in the browser and pairs it with the exact site it belongs to, so whoever holds this file can log in immediately without cracking or guessing anything.

What Was Exposed in the LulzsecCloudLogs File

• Email addresses
• Plaintext passwords
• The URLs of the websites those logins belong to

Why This Matters

Because the passwords are stored as plain text and matched to working login pages, this data is immediately usable for account takeover. Anyone whose credentials appear in this file risks having their email, shopping, or social accounts accessed by someone else, particularly if that password has ever been reused elsewhere.

How Stealer Logs Work

Stealer malware usually arrives hidden inside a cracked program, a fake software update, or a malicious download. Once it runs, it quietly harvests the passwords and autofill data saved in the browser and sends everything back to the attacker in a single log file. Files like "LulzsecCloudLogs Filtered Cookies" are then shared or sold on Telegram channels, which is how analysts came across this one.

Check If You Are Affected

You don't have to wonder whether your information is part of a leak like this one. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs and combolists like this, and tells you right away if your credentials have been exposed.
