Password Reusers Targeted in dingdingding_login_pass 815-Record Leak

HEROIC analysts found a combolist titled "dingdingding_login_pass" uploaded to Telegram on July 3, 2025. The file contains 815 records pairing email addresses with plaintext passwords and the URLs those credentials belong to.

Who This Leak Puts at Risk

This isn't a breach tied to one company or platform, it's a mixed list of credentials gathered from wherever the uploader could find them. That means the people at risk are simply anyone whose email and password happened to end up in this particular file, and especially anyone who uses the same password across more than one account. For those users, 815 leaked logins can open far more than 815 doors.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

A list this size is small compared to some breaches, but the risk to each individual account is exactly the same. Attackers run these smaller combolists through automated tools just as readily as larger ones, testing each email and password pair against popular sites in hopes of a password reuse hit. One successful login can lead to account takeover, and from there, access to personal information or financial details tied to that account.

How Combolists Like This Get Assembled

Combolists are usually built by pulling credentials from a mix of older leaks, phishing campaigns, or stealer log outputs and reformatting them into a single easy-to-use file. Once assembled, they're shared on Telegram channels like the one where dingdingding_login_pass surfaced, ready for anyone to download and try against other accounts.
