Search Your Email: The computer.org Leak Exposed 1,600 Accounts

In June 2026, HEROIC analysts spotted a file uploaded to Telegram labeled "computer.org - 1.600 emails." The upload contains 1,600 records pairing email addresses with plaintext passwords and the URLs of the accounts they belong to, apparently tied to users of the computer.org domain.

Why the computer.org Leak Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who obtains it can log in immediately without needing to crack or decrypt anything. For the 1,600 people in this dataset, that means their email and password combination is sitting in a criminal's file right now, ready to be tested against other websites.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each account

Why This Matters

A leak of 1,600 records may look small compared to headline-grabbing breaches, but it's more than enough for a targeted credential stuffing campaign. Attackers often prefer smaller, more focused lists like this one because the accounts inside them tend to share a common thread, in this case a connection to computer.org, making it easier to guess where else those same credentials might work.

How This Combolist Was Compiled

Uploads like this one are typically built by scraping or purchasing smaller batches of credentials tied to a specific domain or organization, then packaging them into a combolist for sale or free distribution on Telegram. The narrow focus on a single domain, rather than a broad mix, often means the uploader targeted this group specifically.

Check If You Are Affected

If you have ever used an email tied to computer.org, it's worth checking your exposure now. HEROIC's free breach scanner searches your email against more than 400 billion leaked records, including this upload, so you can act before your reused password is tried somewhere else.
