Act Now: Black_Cloudx Stealer Leak Exposes 6,847,808 Logins

Act now, because this one is big. On 25-May-2026, a file called "Black_Cloudx 69" was uploaded to a Telegram channel, and once HEROIC's researchers finished reviewing it, the total came out to 6,847,808 individual records of stolen login data.

Why This Is Dangerous

Almost 6.85 million records is not a number to sit on. Files this large tend to get copied, resold, and redistributed across multiple dark web forums within days of the original upload, wich means the window to change a password before someone tries to use it keeps shrinking the longer people wait.

What Was Exposed

• 6,847,808 total records
• Email Addresses
• Plaintext Passwords
• URLs for each affected account

Why This Matters

Every day this file sits out there, more people download it, and every download increases the chances that your login, if it's in there, gets tried against your bank, your email, or your favorite shopping site. Waiting to act is exactly what attackers are counting on, most victims don't even know they need to change anything untill it's to late.

How Stealer Logs Work

Black_Cloudx, like most stealer logs, is the product of infostealer malware quietly running on infected devices, reading saved browser passwords and autofill entries, then shipping them off to whoever controls the malware. Once collected, the operator packages the results into a single file and distributes it, exactly the kind of file that ended up on Telegram here.

Check If You Are Affected

Don't put this off. Run your email through HEROIC's free breach scanner right now, it checks against more than 400 billion compromised records, including this Black_Cloudx log, so you can act immediately instead of hoping for the best.
