How a Telegram Combolist Exposed 647 rba.com.bn Login Credentials

On 10-Jun-2026, HEROIC analysts identified a small combolist tied to the domain rba.com.bn after it was uploaded by a Telegram user. The file contained 647 records pairing email addresses with plaintext passwords and associated login URLs, a small but complete batch of ready-to-use credentials. Why This Is Dangerous Even at 647 records, this file is dangerous because the passwords are stored in plaintext and matched to specific login URLs. There is no cracking or guesswork involved: an attacker can open the file and immediately try each credential against the site it belongs to. Anyone in this batch who reused their password elsewhere is exposed to an instant login attempt on other accounts. What Was Exposed Email addresses Plaintext passwords Associated website URLs (the login pages tied to each credential) Why This Matters Small combolists like this one still feed into large-scale credential stuffing operations. Attackers often combine dozens of small files like this into bigger lists, then run automated tools that test every email, password, and URL combination against banking sites, email providers, and social platforms. Anyone whose credentials appear here and who reuses passwords faces a real risk of account takeover, identity theft, and financial fraud. How This Combolist Came Together A combolist is a plain text file of email and password pairs, usually gathered from older breaches, phishing pages, or malware-infected devices and then repackaged for resale or free distribution. Small, domain-specific files like this rba.com.bn list are common on Telegram, where sellers break large collections into smaller, targeted batches to sell or give away. The small size does not make the credentials any less real or any less useful to someone looking to break into an account. Check If You Are Affected With 647 email and password pairs exposed in this leak, it takes only a moment to check whether your information is included. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you immediately if you have been exposed.
