Is Your Email in the Second CyanoticCloud Stealer Log Leak?

One day after the first CyanoticCloud stealer log surfaced, HEROIC analysts identified a second dataset carrying the same name, logged on February 16, 2026. This file contains 1,638 records, each one an email address paired with a plaintext password and the URL of the login page it was used on. If your email wasn't in the first CyanoticCloud file, it's worth checking this second batch too, since threat actors often release stolen data in waves rather than all at once.

Why This Leak Is Dangerous for You

If your email and password appear in this file, an attacker already has everything needed to log into your account: no cracking, no guessing, just a plaintext password and the exact site it unlocks. That means the time between this data being uploaded and someone attempting to use it against you could be very short.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs tied to each credential

Why This Matters

If you reused this password anywhere else, your risk isn't limited to the account it was stolen from. Attackers routinely test leaked email and password pairs against banking sites, shopping accounts, and email providers, a technique known as credential stuffing that can lead to account takeover or financial fraud even on services you never expected to be at risk.

How Stealer Logs Work

Like the first CyanoticCloud file, this dataset is a stealer log, data pulled from an infected device rather than a hacked company server. Malware quietly sitting on a victim's computer copies saved browser passwords and the sites they belong to, then ships that information back to whoever controls the infection. The near-identical naming and one-day gap between this file and the earlier one suggest the same source is releasing its haul in sequential parts.

Check If You Are Affected

Don't wait to find out the hard way. HEROIC's free breach scanner lets you search your email against more than 400 billion breached records, including both CyanoticCloud files, so you can see right now whether your information was exposed and change any passwords that need it.
