The KRDCLOUD Leak: 8,245 Emails and Passwords Hit Telegram

HEROIC analysts identified a combolist file labeled "8322_Germany_KRDCLOUD" circulating on Telegram in July 2026, containing 8,245 email addresses paired with plaintext passwords and associated login URLs. The file's name references Germany, but that detail comes from the uploader's own labeling rather than any confirmed, verified population, so we're treating it as an unverified tag rather than a fact about who is affected. Why This Is Dangerous: Because the passwords in this file are stored in plaintext, anyone who downloads it can immediately try each email and password pair against other websites without needing to crack or decode anything. That makes the data usable within minutes of being found. What Was Exposed: The KRDCLOUD file contains three categories of data: email addresses, plaintext passwords, and the URLs of the sites or services those credentials were originally used on. Having all three together makes it easy for an attacker to know exactly where to try a stolen password. Why This Matters: Most people reuse the same password across multiple accounts. If your email and password appear in this combolist, attackers can attempt "credential stuffing," automatically testing the same login pair across banking sites, email providers, and social media until one works. A single reused password can cascade into a full account takeover. How a Combolist Leak Like This Works: A combolist is simply a plain text file pairing usernames or emails with passwords, usually stitched together from older breaches, phishing pages, or malware-infected computers, then repackaged and shared for free or sold on Telegram channels. Unlike a single company breach, a combolist can mix data from dozens of unrelated sources, which is why the original site or company is often impossible to pin down. Check If You Are Affected: You don't have to wonder whether your credentials are sitting in a file like this one. HEROIC's free breach scanner checks your email address against more than 400 billion leaked records, including combolists like KRDCLOUD, and tells you immediately if you need to change a password.
