1676 PCS – 11.03.23 – FREE LOGS uploaded by a Telegram User

We've observed a consistent stream of stealer logs appearing on Telegram channels, but this particular dump caught our attention due to its unusual clarity and the specific combination of data points exposed. It wasn't the largest log file we've seen, but the structured nature of the data – specifically the pairing of email addresses, plaintext passwords, and associated URLs – suggested a targeted collection effort. The fact that these logs were explicitly labeled "FREE LOGS" also hints at a broader distribution network for compromised credentials. This indicates a threat actor more interested in rapid dissemination than prolonged, stealthy access.

The "1676 PCS" Stealer Log: A Snapshot of Compromised Endpoints

A Telegram user uploaded a stealer log file on November 3, 2023, which we've identified as "1676 PCS - 11.03.23 - FREE LOGS." This log contained 29,315 records, painting a clear picture of compromised user endpoints. What really stood out was the inclusion of email addresses, plaintext passwords, and associated URLs within each record. This combination allows for immediate credential stuffing attacks against a wide range of services. The "FREE LOGS" designation suggests this is not a private sale, but rather a widespread distribution, potentially increasing the speed and scale of subsequent attacks.

The breach was discovered when the Darkwatch team monitors Telegram channels known for hosting and distributing stolen data. The explicit naming convention and the availability of the logs for free immediately flagged it as noteworthy. The combination of credentials and associated URLs suggests the stealer malware was likely configured to target specific websites or services, potentially indicating the attacker's focus.

This breach matters to enterprises because it highlights the ongoing threat posed by stealer malware. While individual records are often sold or traded, the release of "FREE LOGS" indicates a shift towards broader distribution, potentially amplifying the impact of these compromises. The presence of plaintext passwords is a particularly concerning element, indicating either poor security practices on the part of the affected users or the compromise of systems storing credentials in an insecure manner.

External Context & Evidence

The rise of stealer logs being freely distributed on Telegram and similar platforms has been noted by several security researchers. BleepingComputer has reported on similar cases where stealer logs are used as initial access vectors for ransomware attacks and other malicious activities. The ease of access to these logs lowers the barrier to entry for less sophisticated attackers, allowing them to participate in credential stuffing and account takeover campaigns. Cybersecurity firms are constantly monitoring these Telegram channels for new leaks and providing mitigation strategies.
