The binus.ac.id Leak Could Unlock Email, Banking, and Social Media

In June 2026, HEROIC analysts identified a file titled "binus.ac.id - 1.132 emails" uploaded to a Telegram channel. The file contains 1,132 records pairing email addresses associated with the binus.ac.id domain to plaintext passwords. Why This binus.ac.id Leak Could Reach Further Than One Account A leaked email and password pair is rarely just about one account. If any of the 1,132 people in this file used the same password for their personal email, banking app, or social media, an attacker holding this list can chain their way from one compromised login into several more, each new account unlocking access to the next. What Was Exposed in This Leak Email addresses Plaintext passwords Associated website URLs Why This Matters Password reuse is what turns a single small leak into a much bigger problem. An attacker who confirms one password works on binus.ac.id will often try it on that same person's email provider, bank, and shopping accounts next. This chained approach is how account takeover, financial fraud, and identity theft spread from a modest leak like this one into much larger consequences for the people affected. How This Combolist Was Likely Assembled Files tied to a specific domain, like this one referencing binus.ac.id, are typically produced by scraping or breaching that site's own systems, then packaging the resulting email and password pairs for distribution on Telegram channels focused on trading leaked credentials. Check If You Are Affected If you have ever had an account tied to binus.ac.id, or if you reuse passwords across multiple sites, check your exposure now. HEROIC's free breach scanner searches more than 400 billion leaked records, including this leak, so you can find out quickly and update any passwords before they are used elsewhere.
