The Logs_23 December Stealer Log Gives Hackers 33,250 Logins

HEROIC analysts identified a stealer log file, referred to as Logs_23 December, uploaded to a Telegram channel on December 23, 2024. The file contains 33,250 records harvested from infected devices, including email addresses, plaintext passwords, and the URLs of the sites those credentials unlock.

Why This Is Dangerous

Because every password in this log is stored in plaintext and paired with the exact web address it belongs to, an attacker does not need to crack or guess anything. They can open the file and immediately start logging into accounts as if they were the real user, on the exact sites the malware recorded.

What Was Exposed in the Logs_23 December Stealer Log

• Email addresses tied to infected devices
• Plaintext passwords, with no hashing or encryption
• URLs identifying which sites and services each login unlocks

Why This Matters

A log of this size, at 33,250 records, gives attackers a ready-made list for credential stuffing across email providers, banks, and social media platforms. Anyone whose credentials appear here faces a real risk of account takeover, identity theft, or financial fraud, often with no idea their device was ever compromised in the first place.

How Stealer Logs Work

Stealer logs come from malware that infects a device, often through a fake download, pirated software, or a malicious attachment. Once installed, it quietly pulls saved logins and browsing data straight out of the browser and sends it back to whoever controls the malware. That data gets bundled into a log file like Logs_23 December and shared or sold through Telegram channels. Because the malware grabs everything saved on the device at once, a single infection can expose logins to many completely unrelated accounts.

Check If You Are Affected

If you are concerned your device may have been infected with stealer malware, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records. It takes seconds to find out if you are exposed and which passwords you need to change right away.
