The DUMP ULP 28.08.2026 Base34 1 File Leaks 26,252,993 Logins

A combolist file labeled DUMP ULP 28.08.2026 Base34 1 surfaced on Telegram, and HEROIC analysts confirmed it holds 26,252,993 records. Dated August 28, 2026, each line in the file pairs an email address with a plaintext password and a matching URL. The only way to know if your information landed in this file is to scan your email.

Why a Plaintext Password Pair Is So Easy to Abuse

Because the passwords in this file were never hashed or encrypted, they can be used the instant someone opens it, no cracking tools required. An attacker only needs to try the exact email and password combination on a handful of popular sites to see where it still works. If that password was reused anywhere else, this single leaked line can unlock multiple accounts belonging to the same person.

What This Combolist Actually Holds

• Email Addresses: identifies a live inbox attackers can target with phishing or credential stuffing attempts.
• Plaintext Password: readable immediately, giving an attacker a working login without any extra effort.
• URLs: points to the exact site each credential pair is meant to unlock.

The Risk This Creates for Reused Passwords

The biggest danger here is password reuse: once a pair from this file is confirmed to work, the same credentials are often tried across email, banking, and shopping accounts automatically. A compromised email account can then be used to reset passwords on other services tied to that address, turning a single leak into a much wider account takeover. Anyone who reused this password on a financial account also risks direct monetary loss.

How Files Like Base34 1 Come Together

A combolist is built by pulling email and password pairs from earlier leaks and stealer logs, then merging them into a single file sorted for bulk use. No one needs to break into DUMP ULP's own systems to create this kind of file, the credentials are simply recycled from data that already leaked elsewhere. The finished list can be fed straight into automated login tools without further work.

Does the Base34 1 Combolist Include Your Email?

Scan your email against this file and HEROIC's wider breach index to see if you are affected. If there's a match, change that password right away, along with any other account where you used it. This applies equally to a personal inbox and a work email address.
