The HQ PL Combo Leak: 5,647 Passwords Exposed. Check Yours.

In September 2024, HEROIC analysts identified a combolist named "HQ PL combo," attributed to a Telegram user going by "professor66699," exposing 5,647 records made up of email addresses, plaintext passwords, and the URLs each login was used on.

Why "HQ" and "PL" Should Get Your Attention

In the world of stolen credential trading, "HQ" means high quality, entries that have been checked and are believed to still work, and "PL" points to a Polish-focused set of accounts. Together, that labeling tells buyers this is not a random, unverified dump, it is a curated list someone has already vetted, which makes the credentials inside more likely to be current and usable right now.

What Was Exposed

• Email addresses linked to Polish accounts
• Plaintext passwords, stored with no encryption
• URLs identifying the exact site each credential belongs to

Why This Matters

Because this list is marketed as high quality, the odds that any given login still works are higher than in a typical unverified leak. That raises the real-world risk of account takeover, credential stuffing on other sites, and financial fraud for anyone in this file who reused the exposed password elsewhere. This is not a theoretical risk, it is a working list built for immediate use.

How a "HQ" Combolist Like This Gets Verified

The process starts with raw stealer log data, malware-harvested logins pulled from infected devices. Distributors like "professor66699" then run checking tools that attempt to log into each account to confirm the credentials still work, discarding the ones that fail. What remains is labeled "HQ," a smaller, higher-value list that sells or trades for more than an unchecked dump because buyers know most of the logins inside are live.

Check If You Are Affected

The passwords in this list were already checked once, do not wait to check yours. HEROIC's free breach scanner checks your email address against a database of more than 400 billion breached and leaked records, so you can find out in seconds and secure any exposed account.
