Bank Customers Targeted in the bankbsi.co.id 20,077 Record Leak
HEROIC analysts found a combolist tied to bankbsi.co.id uploaded to a Telegram channel on 10 June 2026. The file contained 20,077 records combining email addresses, plaintext passwords, and associated URLs linked to accounts on the banking domain.
Why This Is Dangerous
Because this leak is tied to a banking domain, the accounts at risk may be connected to financial services rather than just a social media login or shopping account. With passwords stored in plaintext, anyone who obtains the file can read all 20,077 credential pairs immediately and attempt to log in without needing to crack or decode anything.
What Was Exposed
- Email Addresses
- Plaintext Passwords
- URLs
Why This Matters
Customers connected to bankbsi.co.id are the ones most directly affected by this leak. Attackers commonly take lists like this and run credential stuffing attempts against banking portals and other financial sites, hoping that a reused password unlocks access to real money or personal financial data. Anyone whose email and password appear in this file faces a heightened risk of account takeover, fraud, or identity theft.
How Combolists Work
A combolist pairs usernames or email addresses with their matching passwords in a simple text file, one credential set per line. Rather than being pulled fresh from an infected device, combolists like this one tied to bankbsi.co.id are usually assembled from prior leaks or scraped credentials, then repackaged and shared through Telegram channels and dark web forums. Their simple, ready-to-use format makes them attractive tools for criminals targeting financial accounts.
