HEROIC Researchers Link bamproduktion.se Leak to 1,268 Stolen Logins

What HEROIC Analysts Found

In June 2026, HEROIC's threat intelligence team identified a combolist tied to bamproduktion.se after it was uploaded to Telegram by an individual user. The file contained 1,268 records pairing email addresses with plaintext passwords, along with the account URLs they were used with.

Why This Is Dangerous

Because these passwords were stored and shared in plaintext, anyone who downloads this file can read the password exactly as it was typed, with no cracking or guessing needed. If you reused that password on any other account, an attacker already has what they need to get in.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

Even a leak in the low thousands can do real damage once the data starts circulating. Criminals feed combolists like this into automated tools that test the same email and password pair against banking sites, email providers, and social media accounts, a technique known as credential stuffing. If even one of your accounts shares this password, it can lead to account takeover, identity theft, or financial fraud.

How Combolists Work

A combolist pairs a username or email with a password, typically one pair per line in a plain text file. These lists are often assembled from smaller breaches, stealer malware infections, or scraped login pages, then shared or sold through Telegram channels and dark web forums. Because they require no technical skill to use, combolists remain a common tool behind everyday account takeovers.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against a database of more than 400 billion breached records, including combolists like this one. If your information turns up, change that password right away and anywhere else you have used it.
