Dark Web Intel: 946,420 Credentials From the File Number 1017 Dump

HEROIC analysts identified a combolist labeled "File Number 1017 from 1106.Url_Login_Password" circulating on a Telegram channel in July 2024. The file paired 946,420 email addresses with plaintext passwords and the URLs of the sites those logins belong to, the standard format attackers use to automate login attempts across the web.

Dark Web Intel: Inside the File Number 1017 Combolist

The file's own name gives away how it was built: it is one numbered piece, file 1017, pulled from a much larger batch of 1,106 files organized by URL, login, and password. That structure is typical of large-scale credential dumps that get split into smaller pieces for easier distribution and searching on Telegram and dark web forums. With nearly 950,000 records in just this one piece, the full batch it came from is likely far larger.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to its original login page

Why This Matters

A file of this size is built for automated credential stuffing, where bots test every entry against dozens of popular websites in minutes looking for a working match. Anyone whose email and password appear here faces a real risk that a reused password elsewhere, banking, email, or shopping, gets tried and unlocked. Once an attacker gets into one account, they often use it to reset passwords elsewhere, turning a single leaked login into a much wider account takeover.

How Combolists Like This One Are Built

Combolists are compiled by merging credentials pulled from older breaches, phishing kits, and malware logs into a single searchable file, then formatted as email:password or email:password:URL so they can be fed straight into automated login tools. Splitting a large batch into numbered files, like this one, makes it easier for buyers to purchase or trade specific slices of a larger dataset. A file's age does not make it safe. Old combolists still work against anyone who has not changed the password since.

Check If You Are Affected

You do not have to guess whether your information is sitting in a dump like this one. HEROIC's free breach scanner checks your email address against more than 400 billion leaked records pulled from combolists, stealer logs, and dark web marketplaces. Run a free scan, and if a match turns up, change that password everywhere else you have used it.
