Inside the 600 PCS Free Logs Breach: 9,971 Records Exposed

HEROIC's dark web monitoring identified a stealer log archive titled 600 PCS Free Logs that was shared on a Telegram channel in February 2024. Containing 9,971 stolen records, the dataset was distributed at no cost, significantly broadening the pool of attackers who now have access to these compromised credentials.

The Severe Risk of Exposed Plaintext Passwords

Passwords in this breach are entirely unprotected, stored in plaintext exactly as the victims originally typed them. There is no hashing algorithm to slow down attackers and no encryption to bypass. Each password is a ready-to-use key that can unlock the associated account in seconds, making rapid response essential for anyone whose data is included in this collection.

What Was Exposed

• Email addresses used for login authentication on various websites
• Plaintext passwords extracted directly from browser credential stores
• URLs identifying the exact websites and services where logins were stolen

Credential Stuffing: How Attackers Scale a Single Breach

The 9,971 credential pairs from this breach become ammunition for credential stuffing operations that test each email-password combination against hundreds of online services. Because users frequently reuse passwords, attackers can expect a meaningful percentage of these credentials to work on sites far removed from the original point of compromise. Banking, healthcare, and corporate platforms are all common targets.

Stealer Logs: The Silent Threat on Your Device

The records in 600 PCS Free Logs were created by infostealer malware running undetected on victims' machines. This type of malware typically arrives bundled with pirated applications, game cheats, or through phishing emails containing malicious attachments. It silently monitors all browser activity, capturing login credentials, autofill data, and session cookies before exporting them to remote servers controlled by cybercriminals.

Check If Your Credentials Were Exposed

Knowing whether your data has been compromised is the critical first step toward protecting yourself. HEROIC's breach scanner provides access to more than 400 billion records aggregated from data breaches, stealer logs, and dark web sources. Enter your email address to determine whether your credentials were included in the 600 PCS Free Logs breach or any other known compromise, and secure your accounts without delay.
