hotmails_mix500x_part3 Leak Hands Hackers Your Email and Password

HEROIC analysts identified a combolist circulating on Telegram called hotmails_mix500x_part3, uploaded on 25-Apr-2026 and containing 471 records. Each entry pairs an email address with its plaintext password and a matching login URL, giving whoever downloads the file a ready-made list of working credentials.

Why This Is Dangerous

Because the passwords are stored in plaintext rather than hashed or encrypted, anyone who gets hold of this file can log in immediately, no cracking required. An attacker can open each account, check the inbox for banking notices, password reset emails, and other sensitive messages, and use what they find to move into other accounts the victim owns.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Most people reuse the same password across several sites. That means a single row in this 471-record file can unlock far more than one inbox: attackers routinely run leaked credentials through banking, shopping, and social media logins in a technique called credential stuffing, turning one small leak into a wider account takeover and, eventually, identity theft or financial fraud.

How the hotmails_mix500x_part3 Combolist Was Built

A combolist like this one is not a single company's data breach. It is a compiled file, usually stitched together from older leaks, phishing pages, and malware logs, then cleaned up and reposted by a Telegram user looking for reputation or a quick sale. The "part3" in the name suggests it is one piece of a larger series being released in batches, a common tactic to keep a channel's audience coming back for more.
