LogsDiller Stealer Log: 2,469 Emails and Passwords Exposed

HEROIC analysts identified a stealer log uploaded to Telegram on December 8, 2025, labeled "LogsDiller Cloud_Free_230_94." The file contained 2,469 records collected directly from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts and services those passwords belong to. This is not a breach of a company's own systems. It is the output of malware that silently pulled saved logins off victims' computers.

Why This Is Dangerous

Every password in this log was stored in plaintext, meaning it was never encrypted or scrambled. Anyone who obtains the file can use the exposed email and password combinations right away, without needing to crack anything. Because each credential is linked to the specific URL it opens, attackers also get a direct map of which account each stolen login belongs to.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

A leak of 2,469 records is small compared to some headline-grabbing breaches, but the danger per record is significant. Criminals feed stolen email and password pairs into automated tools to test them across banking sites, email providers, and social platforms, a method known as credential stuffing. Anyone who reused an exposed password elsewhere is at real risk of account takeover, identity theft, or financial fraud.

How Stealer Log Attacks Work

A stealer log comes from information-stealing malware that infects a device, often through a fake download, pirated software, or a malicious attachment. Once active, the malware scans the browser and saved files for stored logins, cookies, and autofill entries, then compiles them into a single log file. That file is packaged and traded, frequently on Telegram, sometimes shared for free as a sample to attract buyers looking for larger batches, which matches the pattern seen here.

Check If You Are Affected

If you're concerned your credentials could be part of this or another leak, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds. It's a fast way to know if you need to change a password or enable two-factor authentication before an exposed credential turns into a compromised account.
