Inside the LogsDiller Log: 1,004 Plaintext Passwords Found

HEROIC analysts identified a stealer log uploaded to Telegram on December 8, 2025, labeled "LogsDiller Cloud_Free_21." The file contained 1,004 records taken directly from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts and services those passwords open. This is not a breach of one company's servers. It is the output of malware that quietly collected saved logins from victims' own computers.

Why This Is Dangerous

The passwords in this log were stored in plaintext, meaning they were never encrypted or hashed. Anyone who obtains the file can use the exposed email and password pairs immediately, with no cracking required. Because each credential is tied to the specific URL it unlocks, attackers also get a direct map of exactly which account each stolen login belongs to.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

A leak of 1,004 records is small next to headline-grabbing breaches, but the danger it carries is not. Criminals load stolen email and password pairs into automated tools and test them across banking sites, email providers, and social platforms, a technique known as credential stuffing. Anyone who reused one of these exposed passwords elsewhere faces a real risk of account takeover, identity theft, or financial fraud.

How Stealer Log Attacks Work

A stealer log is generated by 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 packages everything into a single log file. That file is then shared or sold, frequently on Telegram, sometimes given away for free as a sample to attract buyers looking for larger batches, matching the pattern seen with this LogsDiller upload.

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 only takes a moment to find out whether you need to change a password or enable two-factor authentication before an exposed credential becomes a compromised account.
