Our Analysts Found the 2023-12-30_logsinspector Dump Circulating on Telegram

HEROIC analysts found the 2023-12-30_logsinspector file circulating on a public Telegram channel in January 2024. The file was uploaded by a user calling themselves "logsinspector" and contained 36,814 records pulled from compromised devices. The data included email addresses, plaintext passwords, and the URLs where each set of credentials was entered. Files of this size and type are significant finds because they represent a large volume of working credentials available to anyone who could access that Telegram channel.

Why This Is Dangerous

A stealer log with 36,814 records is not a small incident. Each entry represents a real person whose login credentials were captured by malware without their knowledge. Because the passwords are stored in plaintext, no password cracking is needed. An attacker who downloaded this file can immediately attempt to log into email accounts, banking portals, and workplace systems using the exact usernames and passwords listed in the log. The included URLs make it clear exactly which services each victim was using.

What Was Exposed

The following types of personal data were found in the 2023-12-30_logsinspector file:

• Email addresses
• Plaintext passwords (unencrypted and ready to use)
• URLs identifying the websites where each credential was captured

Why This Matters

When tens of thousands of plaintext passwords and email addresses are combined in a single file, the risk multiplies quickly. Cybercriminals use these datasets for credential stuffing, automating login attepmts across banking apps, email providers, and e-commerce sites in minutes. Even if your most important accounts have unique passwords, the email address itself can be used for phishing or social engeneering. Victims of stealer log leaks often face a wave of unwanted login attempts and spam long after the initial breach.

How Stealer Log Malware Works

An infostealer is a type of malware that silently monitors a device after infection. It typically spreads through fake software downloads, cracked games, or malicious email attachments. Once running, it captures passwords from browsers, active login sessions, and applications. All of this data gets packaged into a log file with a timestamp, which is why files like this one carry a date in the name. The attacker retrieves the log and either uses it directly or shares it on platforms like Telegram, where it can be picked up by hundreds of other criminals.
