1159 Cocos Keeling islands Full Valid Telegram Leak: 337 Exposed

In early May 2026, HEROIC threat intelligence analysts flagged a stealer log file posted to Telegram under the label "1159 Cocos Keeling islands Full Valid," containing 337 records. The "Full Valid" tag is the uploader's own claim that every credential in the file was checked and confirmed to still work. The file includes email addresses, plaintext passwords, and the URLs of the login pages each credential belongs to.

Why a "Full Valid" Label Makes This More Dangerous

Most leaked credential lists contain a mix of old, dead, and working logins. A file marked "Full Valid" tells buyers and other criminals that someone has already done the work of testing each entry, meaning a much higher percentage of these 337 accounts can likely be accessed right now. That verification step is what turns a random pile of leaked data into a ready-to-use tool for account takeover.

What Was Exposed in This Telegram Upload

• Email addresses
• Plaintext passwords
• URLs of the login pages tied to each credential

Why This Matters if You Reuse Passwords

Because these passwords are stored in plain, readable text and appear to already be verified as working, anyone who buys or downloads this file can log in immediately. If the password attached to your email also unlocks other accounts, attackers can move quickly from one account to the next, a technique known as credential stuffing. That can lead to account takeover, unauthorized purchases, or identity theft depending on what else is tied to that login.

How Stealer Logs Get Labeled and Sold on Telegram

Stealer log malware quietly collects saved passwords and login URLs from an infected device, then sends that data back to whoever is running the malware. Sellers often sort the results into batches, sometimes by region, source site, or verification status like "Full Valid," and post them to Telegram channels to attract buyers looking for reliable, working credentials. This 337-record batch appears to be exactly that kind of curated, pre-checked dump.

Check If Your Login Was Included

If your email address or a password you still use anywhere shows up in a batch like this, it is worth knowing sooner rather than later. HEROIC's free breach scanner searches more than 400 billion leaked records, including stealer logs like this one, so you can check your exposure and change any affected passwords before someone else uses them.
