The dplanet 1.ch Leak Surfaced in June. 4,273 Accounts Are Exposed

HEROIC analysts identified a combolist file labeled dplanet 1.ch circulating in a Telegram channel on June 10, 2026. The file exposed 4,273 records containing email addresses, plaintext passwords, and the URLs of the sites those credentials unlock. Why This Leak Is Dangerous: Every password in this file was stored and shared in plaintext, meaning anyone who downloads the list can read the passwords directly with no cracking required. Combined with the matching email address and URL, an attacker has everything needed to log into an account on the first try. What Was Exposed: - Email addresses - Plaintext passwords - URLs linking each credential pair to the service it unlocks Why This Matters: Most people reuse the same password across several accounts. If your email and password from this dplanet 1.ch file also unlock your banking app, work email, or social media, an attacker can move through all of them using simple credential stuffing tools, often within minutes of downloading the list. How a Combolist Like This Works: A combolist is a plain text file where usernames or emails are paired with passwords, one pair per line, often gathered from older breaches, phishing pages, or malware logs and repackaged for resale or free distribution on Telegram. Criminals load combolists into automated tools that test each pair against hundreds of websites at once, flagging any login that works. Check If You Are Affected: HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one. Run a free scan to see if your credentials appear in this or any other breach, and change any reused passwords right away.
