One Telegram Upload. 1,412 Hotmail Logins. The X1415 HQ Leak.

HEROIC analysts found a combolist labeled "X1415 HQ H0TMAIL" that a Telegram user uploaded on July 25, 2026. The file contains 1,412 records pairing email addresses with plaintext passwords, along with the URLs where each credential pair was meant to be used. The name suggests the list was built and verified against Hotmail accounts, and every password in it is stored without encryption.

Why This Is Dangerous

One upload, one file, 1,412 working email and password pairs tied to webmail accounts. That's the entire attack surface here, and it's a large one for a single Telegram post. Because the credentials are plaintext, an attacker can start testing logins the moment they download the file, with no cracking required.

What Was Exposed in the X1415 HQ H0TMAIL Leak

• Email addresses
• Plaintext passwords
• URLs tied to each credential pair

Why This Matters

Email accounts are often the master key to a person's online life. If an attacker gains access to a Hotmail inbox through this leak, they can reset passwords on banking, shopping, and social media accounts linked to that email. This kind of access is exactly how credential stuffing turns into full account takeover, identity theft, and financial fraud.

How a Combolist Leak Works

A combolist pairs usernames or emails with passwords, typically pulled from earlier breaches, phishing pages, or malware that steals saved browser credentials. Verifying which pairs still work against a specific provider, as the name of this file implies, doesn't require hacking that provider directly. It only takes someone testing stolen credentials and sharing the working ones, which is how a file like this ends up circulating on Telegram.
