One Telegram Upload. 11,181 Records. The Arceusulp Combolist Surfaces.

HEROIC analysts identified a second batch from the "Arceusulp" combolist series, uploaded to Telegram on June 20, 2026. This file holds 11,181 records made up of email addresses, plaintext passwords, and the URLs each login belongs to, distributed separately from an earlier Arceusulp batch analysts also tracked.

Why This Is Dangerous

The fact that this data was split into multiple batches suggests whoever compiled it is actively organizing and distributing it in pieces, likely to reach more channels or buyers. Each of the 11,181 records still includes a working plaintext password matched to a specific email and URL, so an attacker can go straight from download to login attempt with no extra steps.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts tied to each login

Why This Matters

Every record in a combolist like this can be run through automated tools that try the same email and password combination across other websites, a tactic known as credential stuffing. If you reused this password anywhere else, it opens the door to account takeover, financial fraud, or identity theft, especially since this data is now spreading across multiple Telegram uploads rather than staying in one place.

How This Combolist Was Assembled

Combolists like the Arceusulp series are usually assembled from older breaches, stealer log outputs, or previously leaked databases, then reformatted into simple email:password pairs that are easy to run through login-checking software. Splitting a large set into separate uploads, as seen here, is a common way distributors spread the same stolen data across more channels and more potential buyers.

Check If You Are Affected

With this data circulating in multiple batches, it is worth checking your exposure sooner rather than later, especially if you reuse passwords. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to show you whether your information appears in this combolist or any other exposure, so you can secure your accounts before someone else gets to them first.
