HUNTERULP Leak: 8,448,311 Logins Exposed Across Industries

HEROIC analysts identified a large stealer log dump labeled HUNTERULP PRIVATE NEW DATABASE, uploaded to Telegram on 17 March 2026. The file contains 8,448,311 records of email addresses, plaintext passwords, and the login URLs tied to each credential, sold by its uploader as a fresh, exclusive database rather than a recycled copy of older leaks.

Why the HUNTERULP Leak Is Dangerous

At over 8.4 million plaintext credential pairs, this file gives attackers a massive, ready-to-run target list spanning whatever sites and services each victim happened to be logged into. Marketed as a private, newly built database, it commands a premium among criminals precisely because it has not been widely circulated or checked against existing password lists, meaning the accounts inside are less likely to have already been secured.

What Was Exposed in HUNTERULP

• Email addresses
• Plaintext passwords
• URLs of the sites where credentials were entered

Why This Matters Across Industries

Because a ULP-format stealer log pulls credentials from every site a victim's browser had saved, a single dump like HUNTERULP can span banking portals, retail accounts, corporate logins, and personal email all at once. That breadth is what makes credential stuffing so effective here, attackers can pivot from one exposed password into account takeover, identity theft, or financial fraud in whichever sector the victim happens to use.

How a Private ULP Stealer Log Like This Is Built

ULP files are generated by infostealer malware that infects a device and quietly copies every saved browser password along with the URL it belongs to. Operators running these infections compile the results into a single database, and labeling it "private" and "new," as with HUNTERULP, signals to buyers that the credentials are recently harvested and have not yet been sold or leaked elsewhere.

Check If You Are Affected

With over 8.4 million records in this single database, checking your own exposure directly is far more reliable than assuming you are safe. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, giving you a clear answer in seconds.
