Stealer Log ca371cf9 Leaks 2,260 Passwords Like a Packed Arena

HEROIC analysts identified a stealer log uploaded to a Telegram channel on November 9, 2025, tagged internally as "09-11-2025_ca371cf9." The file held 2,260 individual records, each combining an email address, a plaintext password, and the login URL tied to that account. It is a mid-size haul, small enough to fly under the radar of major headlines, but plenty large enough to cause real damage.

Putting 2,260 Records Into Perspective

To put it in context, 2,260 stolen logins is roughly the size of a small college's entire student body, or a packed sports arena. Now imagine every single person in that crowd having their email and password handed directly to a stranger. That is effectively what happened here, except the stranger is a cybercriminal with automated tools ready to test every credential within minutes.

Why This Is Dangerous

Unlike a data breach where a company's server is hacked, this data came straight from infected personal devices. That means the credentials were captured at the moment someone typed them in, so they are almost guaranteed to still be active. Attackers do not need to crack anything. They simply plug in the email, password, and URL and walk right into the account.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs (the exact site each set of credentials accesses)

Why This Matters

A log of 2,260 verified logins is a perfect starting point for credential stuffing campaigns. Attackers will run these credentials against banks, retailers, and email providers, betting that at least some victims reused their password elsewhere. Every successful match becomes a potential case of account takeover, identity theft, or outright financial fraud.

How Stealer Logs Work

Info-stealing malware typically arrives disguised as a free download, a cracked application, or a malicious attachment. Once it runs, it quietly harvests saved browser passwords and autofill data, packaging them into a structured file. These logs move fast through Telegram channels and dark web forums, which is why the credentials inside tend to still work when discovered.

Check If You Are Affected

Whether a breach exposes 3 records or 3 million, the risk to you personally is the same if your credentials are on the list. HEROIC's free breach scanner checks your email against over 400 billion compromised records, so you can find out in seconds whether you were caught up in this leak.
