The CyanoticCloud Combolist Gives Attackers 903 Ready-to-Use Logins

HEROIC analysts identified a combolist labeled CyanoticCloud, uploaded by a Telegram user on February 20, 2026. The file contains 903 records combining email addresses, plaintext passwords, and the URLs where each credential works. Why this is dangerous: a combolist like this hands an attacker everything needed to log in without any extra effort. Because the password is already matched to a specific email and URL, there is no cracking or guessing involved. The attacker simply opens the site, enters the credentials, and gains access, and since the passwords are plaintext, they are immediately usable the moment someone downloads the file. What was exposed: email addresses, plaintext passwords, and the URLs paired with each login. Why this matters: combolists like this one are a direct input for credential stuffing tools that test the same email and password across hundreds of other websites. Anyone who reused this password elsewhere risks account takeover, identity theft, and financial fraud spreading well beyond the original account. How combolists work: a combolist is a compiled list of username-or-email and password pairs, usually gathered from older breaches, stealer malware, or phishing campaigns, then reformatted and bundled together for resale or free distribution. Criminals load these lists into automated tools that attempt each pair across many sites at once, looking for accounts where the same password still 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 scan to find out if your credentials were exposed and learn which passwords need to change.
