Casper Cloud Free Stealer Log Exposes 78,845 Login Records

In June 2026, a stealer log tied to Casper Cloud Free surfaced after a user posted it in a Telegram channel, and it did not take long for researchers to notice. The file contained 78,845 records pulled straight from infected devices, meaning real people's saved logins were sitting out in the open for anyone who found the link. This is the kind of leak that spreads fast because it costs criminals nothing to grab it and share it again.

Why This Is Dangerous

Stealer logs are especially nasty because they don't just contain a username and password pair, they usually come bundled with the exact website the credentials belong to. That means whoever downloads this file doesn't have to guess where to try the login, they already know. Combine that with the fact the passwords here were stored in plaintext, and you have a recipe for imediate account takeover if the victim reused that password anywhere else.

What Was Exposed

• 78,845 total records tied to the Casper Cloud Free upload
• Email addresses
• Plaintext passwords
• URLs linking each credential pair to the site it was used on

Why This Matters

Most people don't realize how much malware quietly captures in the background before they ever notice something is wrong. A single infected download can hand over years of saved logins in seperate browser profiles, all at once. Once a file like this lands on Telegram, it gets copied and recirculated by other threat actors, so the original 78,845 victims are definately not the only ones who will see their information again.

How Stealer Logs Work

A stealer log comes from malware that infects a computer, often through a cracked program, a fake download, or a malicious email attachment. Once it's running, it quietly scans the browser for saved passwords, autofill data, and session cookies, then bundles everything into a text file and sends it back to whoever controls the malware. That file gets sold, traded, or in this case, just uploaded for free where anyone on Telegram can grab it.

Check If You Are Affected

If you think your email or an old password might be sitting in a leak like this one, it's worth checking rather than hoping for the best. HEROIC runs a free breach scanner built on a database of more than 400 billion leaked records, so you can search your own information and see what has already been exposed. It only takes a minute, and it beats finding out the hard way.
