Inside the active byamrb27 Combolist: How 12,294 Logins Leaked

HEROIC analysts uncovered a combolist labeled active byamrb27, uploaded to a Telegram channel in July 2026, just weeks before this report. The file contains 12,294 records of email addresses, plaintext passwords, and the URLs tied to each login, apparently named after the Telegram user who posted it. Why This Is Dangerous: Because this combolist surfaced so recently, the credentials inside it are more likely to still be in active use than those from older leaks. With 12,294 plaintext email and password pairs available, attackers have a fresh, ready-to-use list to run against other sites right now. What Was Exposed in the active byamrb27 Leak: Email addresses. Plaintext passwords. Login URLs for each account. Why This Matters: Fresh combolists like this one are especially useful for credential stuffing attacks, where automated tools rapidly test stolen logins across banking, email, and shopping platforms. The more recently a list was compiled, the higher the odds that a given password hasn't yet been changed, which is exactly why speed matters when a leak like this appears. How Telegram Combolists Like This Spread: Individual users on Telegram frequently post combolists under their own handle, as appears to be the case here, either compiling credentials themselves from malware logs and phishing kits or reposting files obtained from other sources. The channel format lets these files reach interested buyers quickly, often within hours of being uploaded. Check if You Are Affected: Given how recently this file appeared, checking your exposure now matters more than usual. HEROIC's free breach scanner searches over 400 billion leaked records, including recent combolists like this one, so you can find out immediately and change any passwords still in use.
