compucenternet.com.br Customers Hit by 9,988-Record Password Leak

The compucenternet.com.br Combolist: What HEROIC Analysts Found. HEROIC analysts identified a combolist file referencing compucenternet.com.br that was uploaded by a Telegram user in June 2026. The file contains 9,988 records pairing email addresses with plaintext passwords, along with the URLs of the login pages those credentials belonged to. Why This Is Dangerous. A combolist puts working email and password combinations in one file that anyone can plug into automated login tools. Because these passwords were stored in plaintext, there is no scrambling to undo, the password is sitting there in readable form. What Was Exposed: Email addresses tied to individual accounts. Plaintext passwords with no encryption. The URLs of the login pages those credentials were tied to. Why This Matters. Files like this are built for credential stuffing, automated attempts to reuse a leaked email and password pair across many other websites. Anyone in this set of 9,988 accounts who reused their password elsewhere, on email, banking, or shopping sites, faces a real risk of those other accounts being taken over too. How Combolists Work. Combolists are typically assembled by combining login data from smaller breaches, phishing campaigns, or malware infections into one large file of matched email and password pairs. These files circulate on forums and messaging apps like Telegram, where they get picked up by attackers running automated credential stuffing tools against popular websites. Check If You're Affected.
