In one example, a threat actor posted a “99k HQ Combolist” on a breached forum, and security researchers found a 2.3% match rate to known stealer logs. That may sound low, but 2.3% of 99,000 is still over 2,200 credentials. With automated tools, an attacker can test all 190,000 pairs in a matter of hours, and even a low single‑digit success rate translates into thousands of compromised accounts.
