The Rediff.com Leak Has as Many Records as a Sold-Out Arena Crowd

HEROIC analysts identified a combolist labeled rediff.com - 19.208 emails, shared on Telegram on 10 June 2026. HEROIC's verification puts the confirmed count at 19,204 records tied to the rediff.com domain, each pairing an email address with a plaintext password and a related URL. Why This Is Dangerous: With more than 19,000 credentials stored in plaintext, an attacker doesn't need to crack a single password, they can load this file directly into automated tools and attempt to log into every one of these accounts within minutes. What Was Exposed: - Email addresses on the rediff.com domain - Plaintext passwords - URLs linked to each account Why This Matters: A leak of this size, filtered to a single email domain, gives an attacker a ready-made list to run credential stuffing against that specific user base. Anyone with a rediff.com account in this file faces a real risk of account takeover, and further risk if that same password is used on banking or shopping accounts elsewhere. How a Combolist Like This Works: This file was assembled by filtering a larger pool of stolen credentials down to just the accounts using a rediff.com email address, a common practice that makes a combolist more valuable to attackers who want to target users of one specific service rather than sorting through unrelated data. Check If You Are Affected: Check your email address against more than 400 billion records in HEROIC's breach database with HEROIC's free breach scanner to see if your rediff.com account is part of this leak.
