Inside the Adeder.com Combolist: How 1,969 Passwords Leaked

HEROIC analysts found a combolist tied to the site adeder.com circulating on a Telegram channel in June 2026. The file contained 1,969 records pairing email addresses with plaintext passwords and the URLs each credential was used on. Why this is dangerous: because the passwords in this file are stored in plaintext, anyone who obtains it can attempt to log in immediately, without needing to crack or decrypt anything first. That makes the data usable right away by attackers of any skill level. What was exposed: email addresses, plaintext passwords, and associated URLs indicating where each credential was originally used. Why this matters: if any of these 1,969 people reused their password on other websites, attackers can use the same login information to try breaking into email, banking, or social media accounts, a technique known as credential stuffing that can lead to account takeover and identity theft. How combolists like this one work: a combolist bundles usernames or email addresses together with passwords, usually gathered from earlier breaches, malware infections, or manual scraping of specific sites, then packaged under a label like adeder.com and shared or sold on Telegram channels and dark web forums. Because the credentials are already matched and organized, combolists let attackers automate large batches of login attempts across many services at once. Check if you are affected: if you have an account with adeder.com or reuse passwords across sites, it is worth checking whether your information appears in this leak.
