17-12-2025-1278PCSOTTOMANCLOUDBOT uploaded by a Telegram User

We noticed a recent upload to a public Telegram channel on December 18, 2025, containing a stealer log file. This file, identified as "17-12-2025-1278PCSOTTOMANCLOUDBOT," appears to be a dump from a credential-stealing malware operation. What struck us was the inclusion of plaintext passwords alongside email addresses and associated API host URLs, indicating a direct compromise of user credentials and potentially their access to services. The relatively small pwned count, while not enterprise-scale, suggests a targeted or nascent campaign, making its early detection crucial.

The breach breakdown reveals a stealer log containing 106,61 records, discovered via a public Telegram upload on December 18, 2025. The data types exposed include email addresses, plaintext passwords, and associated URLs, likely representing API endpoints or compromised web services. The source structure points to a credential-stealing malware, which exfiltrates this information from infected endpoints. The leak location on a public Telegram channel signifies a deliberate act of dissemination, likely for sale or further exploitation. The significance lies in the direct exposure of credentials, bypassing more complex attack vectors and enabling immediate account takeover.

While this specific incident has not garnered widespread media attention, the methodology aligns with ongoing trends in credential stuffing and account takeover attacks. Numerous cybersecurity reports from late 2025 and early 2026 have highlighted the persistent threat posed by infostealer malware, with threat intelligence firms like Mandiant and CrowdStrike detailing the evolving tactics of these actors. The ease with which such logs are shared on platforms like Telegram underscores the need for robust endpoint security and vigilant credential management practices across the organization.

Our attention was drawn to a notification regarding a data leak dated December 18, 2025, originating from a Telegram user. The uploaded file, designated "17-12-2025-1278PCSOTTOMANCLOUDBOT," contained a significant volume of sensitive information. What immediately raised concern was the nature of the data: email addresses, plaintext passwords, and URLs, suggesting a direct compromise of user authentication mechanisms. The discovery on a public platform indicates a lack of control over the exfiltrated data and a potential for widespread misuse.

The breach analysis indicates that a stealer log file, uploaded by an anonymous Telegram user on December 18, 2025, exposed 10,661 records. This dataset comprises email addresses, plaintext passwords, and associated URLs, likely representing compromised online services or API endpoints. The log's structure suggests it was generated by an infostealer malware, which systematically harvests credentials from infected systems. The exposure on a public Telegram channel means this data is readily accessible to malicious actors, significantly increasing the risk of account compromise and further downstream attacks. The immediate threat is the potential for these credentials to be used in credential stuffing attacks against other services.

This type of incident, while not individually making headlines, is a recurring theme in cybersecurity. Research from various threat intelligence providers, including Recorded Future and Cybersixgill, consistently reports on the proliferation of stealer logs sold on dark web marketplaces and shared in public forums. The ease of access to such compromised credentials fuels a significant portion of account takeover incidents, impacting both individuals and organizations globally. The specific malware family or campaign behind this particular log remains unconfirmed without further forensic analysis.

We observed a data dump appearing on December 18, 2025, attributed to a Telegram user and labeled "17-12-2025-1278PCSOTTOMANCLOUDBOT." The contents of this dump are particularly concerning due to their direct implications for user authentication. What stood out was the presence of plaintext passwords alongside email addresses and associated URLs, indicating a critical failure in credential security. The discovery on a public channel suggests a deliberate act of data exfiltration and subsequent dissemination, bypassing any attempts at containment.

The breach details reveal a stealer log file, uploaded on December 18, 2025, containing 10,661 records. The exposed data types are email addresses, plaintext passwords, and URLs. The source structure is consistent with logs generated by credential-stealing malware, which targets and exfiltrates sensitive information from compromised endpoints. The leak location on a public Telegram channel means this data is immediately available for exploitation. The primary threat is the direct compromise of accounts, enabling attackers to gain unauthorized access to various online services and potentially sensitive internal systems if corporate credentials are included.

While this specific upload might not have triggered major news cycles, the underlying threat is well-documented. Cybersecurity advisories from organizations like the Cybersecurity and Infrastructure Security Agency (CISA) frequently warn about the dangers of infostealer malware and the subsequent sale of compromised credentials. The methodology observed here aligns with numerous reports detailing the ongoing battle against credential theft, where threat actors leverage easily obtainable data to facilitate further malicious activities.
