464 PCS Free Logs Leak Puts 5,882 Credentials at Risk

HEROIC detected a freely distributed stealer log package labeled 464 PCS Free Logs on a Telegram channel in January 2024. The archive contains 5,882 records of stolen credentials extracted from compromised devices, and its free availability means a wide range of threat actors now possess these login details.

Plaintext Passwords Offer Attackers a Direct Path In

The passwords exposed in this collection are stored in plaintext with no encryption or hashing applied. This means any person who downloads the dataset can immediately attempt to log in to the associated accounts. Plaintext exposure eliminates the time and effort normally required to crack password hashes, dramatically accelerating the attack timeline from weeks to mere moments.

What Was Exposed

• Email addresses linked to user accounts across multiple platforms
• Plaintext passwords captured in real time from victim devices
• URLs documenting the specific sites and services that were compromised

From One Stolen Password to a Full Account Takeover Chain

Credential stuffing attacks thrive on password reuse. Once attackers acquire the 5,882 email-password pairs from this leak, they systematically test each combination against banking sites, email providers, social platforms, and corporate VPNs. A single match can trigger a cascade of compromises, especially when the breached email account is used for password resets on other services.

How Infostealer Malware Creates These Log Collections

Stealer logs like 464 PCS Free Logs are produced by infostealer malware that infects computers through malicious downloads, fake software updates, or compromised advertisements. The malware runs silently in the background, capturing credentials as users type them into login forms or as they are retrieved from browser password managers. The stolen data is then relayed to the attacker and eventually packaged into collections that circulate freely or are sold on underground markets.

Check If Your Credentials Were Exposed

Take control of your digital security by scanning your email address against HEROIC's database of over 400 billion breach records. HEROIC aggregates data from known breaches, stealer log collections, and dark web leaks to give you a comprehensive view of your exposure. If your credentials appear in the 464 PCS Free Logs dataset or any other breach, you will know exactly which accounts need immediate password changes and additional protections like two-factor authentication.
