Mix combo_1 Uploaded by a Telegram User: 17,869 Records Exposed

The Mix combo_1 List Still Circulating With 17,869 Records

HEROIC analysts identified a combolist file named "Mix combo_1" that traces back to December 2024 but continues to be shared on Telegram. The file holds 17,869 records, each pairing an email address with a plaintext password and an associated URL. Its size and generic name suggest it was built by merging several smaller stolen credential sets into one larger, more sellable file.

Why This Is Dangerous

All 17,869 passwords in this file are stored in plaintext, giving anyone who obtains it instant access to readable credentials with no cracking required. The age of the file does not reduce the danger. Many people never update passwords tied to accounts they rarely use, so a nearly two-year-old combolist can still open doors that were never closed.

• Email Addresses
• Plaintext Password
• URLs

Why This Matters

A combolist of nearly 18,000 records is large enough to fuel a serious credential stuffing operation, with automated tools testing each email and password pair against banking sites, email providers, and online retailers. Anyone in this file who reused a password anywhere else faces a genuine risk of account takeover, financial fraud, or identity theft.

How a Merged Combolist Like Mix combo_1 Is Assembled

A mixed combolist is created by combining several smaller lists of stolen credentials, typically sourced from older breaches, phishing pages, and malware-infected devices, into one larger file. Combining multiple sources into a single combolist makes the final product more attractive to buyers on Telegram, who prefer bigger lists with better odds that at least some entries still work.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against more than 400 billion leaked records, including older combolists like Mix combo_1 that are still being traded. If your email turns up in a search, updating that password now closes an exposure that may have been open for years.
