Inside the ‘HQ Mix Combo’ Leak: 69,727 High Quality Login Pairs

HEROIC analysts identified a combolist labeled HQ mix combo test crasco_owner uploaded to a Telegram channel on August 15, 2024. The listed country associated with this file is a generic, unverified tag rather than confirmed geographic targeting, so this report focuses on what's actually confirmed: 69,727 records, each pairing an email address or username with a plaintext password and a URL. Why This Is Dangerous: HQ, short for high quality, is a label sellers use to signal that a combolist has been cleaned and checked rather than dumped raw. That claim matters because a curated file like this is more likely to contain working logins than an unfiltered one, making the 69,727 records inside more immediately useful to anyone who buys or downloads it. What Was Exposed: - Email addresses and usernames - Plaintext passwords - URLs tied to each login Why This Matters: A combolist marketed as high quality is built specifically for credential stuffing, where automated tools run each login against banking, email, and shopping sites at scale. If your password appears here and you've used it elsewhere, the risk isn't hypothetical: account takeover, fraud, and identity theft all start the same way, with one working password. How a Combolist Like This Works: Sellers assemble combolists from stealer logs and older breaches, then run automated checks to filter out dead logins before marketing the survivors as HQ or high quality. The crasco_owner tag in the file name likely identifies the trader or channel responsible for compiling and distributing it, a common practice in Telegram combolist trading. Check If You Are Affected: Rather than rely on a seller's quality claims, verify your own exposure directly. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including combolists like this one, so you can find out in seconds and change any passwords that need it.
