Search Your Email: The 1676 PCS Stealer Log Exposed 29,315 Accounts on Telegram

HEROIC analysts identified a stealer log uploaded to a public Telegram channel on November 3, 2023, labeled "1676 PCS - 11.03.23 - FREE LOGS." The file contained 29,315 records, each pairing an email address with a plaintext password and an associated URL. The fact that these logs were distributed freely, rather than sold privately, suggests the threat actor prioritized rapid, wide-scale dissemination over stealthy exploitation. This type of release accelerates downstream attacks because it puts usable credentials into the hands of thousands of bad actors at once.

Why Plaintext Passwords in a Free Telegram Dump Are Especially Dangerous

Most credential leaks contain hashed passwords, which require additional effort to crack before they can be used. This dump is different. Every password in the 1676 PCS log is in plaintext, meaning anyone who downloaded the file can immediately attempt to log into accounts without any extra steps. Paired with the associated URLs, attackers know exactly which websites to target first. The combination makes this a plug-and-play toolkit for account takeover.

Because the logs were posted publicly on Telegram and labeled as "free," the file likely spread to dozens of secondary channels and forums within hours of the original upload. By the time most users would recieve any notification, the credentials had already been tested across multiple platforms.

What Was Exposed in the 1676 PCS Log

• Email addresses
• Plaintext passwords
• Associated URLs (the specific websites where credentials were harvested)

Why This Matters Beyond the 29,315 Records

Password reuse is the primary reason a single stealer log can cause damage far beyond its original scope. A user whose credentials appear in this dump may have the same email and password combination active on their banking portal, email inbox, or employer VPN. Attackers routinely run credential stuffing tools that test a single stolen login against hundreds of services automatically.

The inclusion of specific URLs in this log is a seperate concern entirely. It tells analysts, and attackers, exactly which services were actively targeted by the underlying malware. That intelligence can be used to prioritize which accounts to attack first, dramatically increasing the efficiency of follow-on campaigns including identity theft and financial fraud.

How Stealer Log Malware Works

Stealer logs are produced by a category of malware designed to silently harvest credentials from an infected device. Once installed, typically through a phishing email, a malicious download, or a compromised software installer, the malware scans the device for saved browser passwords, autofill data, session cookies, and stored credentials. It then packages everything into a structured log file and transmits it back to the attacker's command server.

The "1676 PCS" designation in this log likely refers to the number of unique endpoints, or infected machines, from which data was collected. Each piece count represents a real person's device that was compromised. The logs are then sorted, packaged, and distributed, sometimes sold, sometimes released for free as was the case here, through Telegram channels frequented by cybercriminals.

What makes stealer logs particulary damaging is that they bypass encryption entirely. The malware captures passwords at the moment a user types them or pulls them directly from the browser's local credential store before any encryption is applied. No amount of HTTPS protects against this type of attack once a device is infected.
