The Ambro.com Leak: 879 Email and Password Pairs Hit Telegram

In June 2026, HEROIC analysts identified a combolist file uploaded to Telegram containing 879 records tied to the ambro.com domain. Each record pairs an email address with a plaintext password and the URL the login was captured from. Why This Is Dangerous: With the passwords stored in plain, unencrypted text, no technical skill is required to use this data. Anyone who has the file can immediately try each email and password pair against other accounts belonging to the same person. What Was Exposed: - Email addresses - Plaintext passwords - URLs linked to each login Why This Matters: Even a small leak like this one is enough to power a targeted credential stuffing run against the 879 people whose accounts appear in it. Because password reuse is common, a single leaked login tied to one domain can expose email, banking, or shopping accounts elsewhere, opening the door to account takeover, identity theft, and financial fraud. How a Combolist Like This Works: This kind of file is compiled from a mix of sources, older breaches, phishing pages, and malware-infected devices, then filtered down to addresses from a single domain before being uploaded or sold on Telegram. Sorting by domain, as was done here with ambro.com, makes the list more useful to attackers who want to target a specific organization's users. Check If You Are Affected: Search your email address in HEROIC's free breach scanner, which checks against more than 400 billion exposed records, including this ambro.com combolist. If you find a match, change that password immediately and anywhere else you have reused it.
