Days After One Leak, CyanoticCloud Exposed 979 More Logins

In February 2026, just three days after an earlier 1,454-record file surfaced, HEROIC analysts identified a second stealer log from the same "CyanoticCloud" Telegram account. This new file contained 979 records, again including email addresses, plaintext passwords, and the URLs each login was tied to. The short gap between the two releases suggests the operator behind CyanoticCloud is actively harvesting and posting fresh batches of stolen credentials rather than releasing a single one-time dump.

Why This Is Dangerous

A source that releases multiple stealer logs within days of each other is dangerous because it points to an ongoing operation rather than a single isolated incident. Each of the 979 records in this file pairs an email address with its plaintext password and the exact site it unlocks, giving an attacker immediate, ready-to-use access. Anyone who checked a previous CyanoticCloud leak and came up clear could still be affected by this newer batch.

What Was Exposed

This leak included the following data types:

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Repeated leaks from the same source in a short window are a strong sign of active credential stuffing and account takeover activity, since fresh batches of stolen logins are typically tested against banking, email, and social media platforms as soon as they are compiled. Because so many people reuse passwords, being caught in even one of these smaller drops can expose far more than the original infected device or account.

How Stealer Logs Work

A stealer log is produced by information-stealing malware, malicious software that infects a device through fake downloads, cracked software, or phishing links, then quietly collects saved browser passwords and active sessions. When an operator like CyanoticCloud releases multiple logs in quick succession, it usually means they are running an ongoing infection campaign, continuously harvesting new victims and packaging the results into fresh files rather than working from a single static list.

Check If You Are Affected

With this operator releasing new batches every few days, checking your exposure regularly is worth the few seconds it takes. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like both CyanoticCloud releases, so you can find out quickly and update any reused passwords before they are used against you.
