BananaLogs 1315count uploaded by a Telegram User

We've been tracking a steady rise in stealer log activity on Telegram, but what really caught our eye with this particular dump was the unusual mix of data types within a single log file. It wasn't just the typical credentials; this one included a significant number of API host URLs alongside plaintext passwords and email addresses. The combination suggests a potential targeting of developers or individuals with access to sensitive backend systems. This breach, which we've dubbed "BananaLogs 1315," highlights the continued risk posed by stealer logs and the potential for lateral movement within compromised environments.

BananaLogs 1315: 30k+ Credentials, URLs, and Emails Exposed Via Telegram Stealer Log

In early November 2023, a threat actor uploaded a stealer log file, dubbed "BananaLogs 1315," to a Telegram channel. The file contained 30,335 records detailing endpoints, email addresses, API host URLs, and plaintext passwords. What caught our attention was the inclusion of API host URLs alongside standard credential data, suggesting a possible focus on targeting individuals with access to sensitive systems or development environments. The plaintext passwords, while not uncommon in stealer logs, significantly increase the immediate risk to affected users and organizations.

The breach was discovered on November 3, 2023, when the file was uploaded to Telegram. The size of the log file and the presence of API host URLs quickly set it apart from routine stealer log dumps. This combination suggests a possible attempt to compromise not just individual accounts, but also potentially backend systems or APIs connected to the exposed credentials.

This breach matters to enterprises now because it underscores the persistent threat posed by stealer logs and the potential for compromised credentials to be used for lateral movement within a network. The inclusion of API host URLs expands the attack surface and increases the likelihood of successful exploitation. This highlights the need for robust credential monitoring, multi-factor authentication, and regular security audits to identify and mitigate potential vulnerabilities. The incident ties into broader threat themes we’re seeing, specifically the proliferation of stealer logs on Telegram marketplaces and the automation of attacks leveraging compromised credentials.

The rise in stealer log activity has been widely reported. BleepingComputer has covered numerous incidents involving stealer logs being sold and distributed on Telegram and dark web forums. These logs often contain a wealth of sensitive information, including credentials, cookies, and browsing history, which can be used for a variety of malicious purposes, including account takeover, identity theft, and corporate espionage. As observed in other stealer log breaches, compromised credentials are often traded and sold on various forums, increasing the risk of exploitation over time. The risk is amplified in this case due to the presence of plaintext passwords.
