Everyday Users Targeted in the CyanoticCloud Leak of 1,438 Logins

HEROIC analysts identified a combolist file named CyanoticCloud that a Telegram user uploaded on February 18, 2026. It contains 1,438 records of email addresses paired with plaintext passwords, along with the URLs each pair was taken from. Why This Is Dangerous: There is no single company or platform behind this leak, it is a mixed batch of everyday consumer logins gathered from various sources. That makes it just as dangerous as a leak from a named company, because the accounts inside belong to real people who have no way of knowing their credentials are circulating unless they check. What Was Exposed: - Email addresses - Plaintext passwords - URLs identifying each credential's source Why This Matters: Ordinary internet users are the exact target of files like this. Attackers do not need a household name breach to cause damage, a mixed combolist of 1,438 working logins is enough to run credential stuffing attacks against email, banking, and social media accounts, leading to account takeover and potential identity theft for anyone caught in the list. How This Combolist Was Assembled: Mixed-source combolists like CyanoticCloud are typically pulled together from smaller breaches, phishing kits, and infostealer malware logs, then merged into one file and given a distinct name before being shared on Telegram. The unusual name likely comes from the channel or seller who assembled it rather than any single hacked service. Check If You Are Affected: HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including mixed combolists like CyanoticCloud, so you can find out in seconds if your credentials are part of this exposure and take action to protect your accounts.
