If You Reuse Passwords, the Deezer Accounts Leak Should Worry You

HEROIC analysts found a combolist titled x42 Deezer Accounts uploaded by a Telegram User, shared on 24-Jun-2026. The file contains 42 records pairing email or username with plaintext passwords, along with the URLs of the accounts they unlock.

Why This Is Dangerous

If you reuse passwords across different accounts, this small leak could matter far more than its size suggests. The passwords in this file are plaintext, meaning anyone who downloads it can read them immediately and try them wherever else you might have used the same login.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the affected login pages

Why This Matters

A list of only 42 records might look minor, but each one is a working set of credentials someone can try right now. If you reuse passwords, one exposed login is often all it takes for an attacker to attempt credential stuffing against your email, banking, or social media accounts, opening the door to account takeover, financial fraud, or identity theft.

How Combolists Work

A combolist pairs stolen usernames or emails with matching passwords, usually pulled together from older breaches, phishing pages, or stealer malware and packaged into a single file. Criminals share and sell these lists on Telegram because they can be fed directly into automated tools that test each pair against many different websites in seconds. A small combolist like this one can still be effective, since it takes only one reused password to give an attacker a foothold.

Check If You Are Affected

Do not assume a small leak means low risk. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, and tells you right away if you were exposed. Run a free scan now and update any passwords you have reused elsewhere.
