The sina.com Telegram Dump Contains Exactly 763 Login Pairs

HEROIC analysts found a combolist referencing "sina.com" that a Telegram user uploaded on June 12, 2026. The file contains 763 records pairing email addresses with plaintext passwords, along with the URLs where each credential pair was meant to be used. Every password in the file is stored without encryption, so it can be used immediately by anyone who has it.

Why This Is Dangerous

763 is a precise, confirmed number of working credential pairs sitting in one file, ready for an attacker to use. There is no cracking or guessing involved. If you or someone you know had an account tied to sina.com and reused that password elsewhere, the exposure extends well beyond a single site.

What Was Exposed in the sina.com Leak

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

Why This Matters

Lists like this one power credential stuffing attacks, where attackers use automated tools to try each stolen email and password combination against banking sites, email providers, and social media platforms. Because password reuse is common, a single leaked credential can open the door to account takeover, identity theft, and financial fraud on services that have nothing to do with the original account.

How a Combolist Leak Works

A combolist pairs usernames or emails with passwords, typically compiled from earlier breaches, phishing pages, or malware that steals saved browser credentials. Building one doesn't require hacking a specific company's systems. It only takes someone gathering and sharing credentials that already exist, which is how this file referencing sina.com came to be uploaded on Telegram.
