1,007 Logins Leaked in the 'USA Uploaded by a Telegram User' Dump

In May 2026, HEROIC analysts tracked a combolist that a Telegram user uploaded directly to a public channel, dated May 21, 2026. The file contained 1,007 records tied to accounts in the United States, pairing email addresses with plaintext passwords and the URLs where those credentials were originally used. Why This Telegram Combolist Is Dangerous Because the passwords in this file are stored in plaintext, anyone who downloads the list can read and use them immediately, no cracking or decryption required. Pairing each password with its matching URL tells an attacker exactly which site or service the login belongs to, which makes it far easier to log in successfully on the first try. A list this ready to use can be picked up by low-skill attackers just as easily as experienced ones. What Was Exposed Email addresses Plaintext passwords, stored in readable, unencrypted form URLs showing where each set of credentials was used Why This Matters if Your Email Was in This File Combolists like this one are built for one purpose: getting into accounts. Attackers feed lists of email and password pairs into automated tools that try each combination against banking sites, email providers, and social media platforms in a process known as credential stuffing. If you reused this password anywhere else, that account is now at risk too. A successful login can lead to account takeover, unauthorized purchases, and identity theft if personal details are exposed once inside. How a Telegram Combolist Like This Gets Built A combolist is simply a compiled file of username or email and password pairs, often gathered from older breaches, malware infections, or manual collection, and repackaged into a single list. Unlike a breach of one company's database, a combolist can mix data from many different sources. Telegram has become a common distribution point because channels make it easy to share and re-share these files quickly and anonymously, often for free or in exchange for a small fee. Check If Your Email Was in This Combolist If you had an account tied to the United States and are unsure whether your credentials appear in this leak, you do not have to guess. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, including combolists like this one, so you can find out quickly and change any passwords that need it.
