What We Know About the 13.6M Record HUNTERULP File 8 Leak

Among the largest files in this batch is HUNTERULP UHQ DATABASE 07-25-2026 8, which HEROIC analysts confirmed holds 13,598,477 plaintext email and password records, each paired with the URL of the site it belongs to. The file traces to a Telegram post dated 16 August 2026. What we know so far: the format is a standard combolist built for mass credential testing, and checking your own exposure only takes a moment through a scan your email lookup.

What the numbers tell us about the risk

At 13.6 million records, this file sits among the larger combolists HEROIC has logged this month. Its size alone makes it attractive to attackers running automated credential stuffing tools, since even a small success rate against that many attempts still produces a large number of working logins.

What was exposed

• Email addresses single out accounts that are real and active.
• Plaintext passwords need no cracking and work as soon as they are tested.
• URLs show exactly which login page each pair is meant for.

Why this matters

What we know from files like this is that account takeover risk rises sharply wherever passwords have been reused. A password captured years ago for one service can still open a current account if it was never changed or if the same password was carried over to a new login.

How this breach type works

Combolists are assembled from credentials gathered across multiple earlier breaches and stealer log infections, merged into a single file and labeled with a compilation date rather than tied to one company's incident. The name and date describe when the file was packaged and posted, not a single hack.

What should you check first?

Start with a free scan your email to see whether your address appears among the 13.6 million records. If it does, change that password immediately and review anywhere else you may have reused it, including work email accounts alongside personal ones.
