Reputation.com has left a staggering 320GB of logs exposed online, encompassing approximately 120 million records. This significant breach includes sensitive information such as cookies, timestamps, and unique identifiers, which pose a severe risk to account security for numerous high-profile brands. Despite being alerted to this vulnerability by cybersecurity outlet Cybernews, the database appears to still be publicly accessible.
Reputation.com, headquartered in the United States, specializes in online reputation management (ORM) and customer experience (CX) tools designed for businesses. Recent findings revealed a vast, unsecured database available to anyone familiar with its location. According to a report from Cybernews, security researchers discovered this “massive data chest” in mid-August 2025, highlighting potential risks tied to inadequate security practices within the firm.
The investigative team uncovered that various applications within Reputation.com were continuously generating logs that were stored on a server equipped with a data visualization tool aimed at aiding enterprises in managing large datasets. The compiled logs were meticulously organized into monthly indices, some containing millions of documents, thereby reflecting the high activity level of the systems in use.
Researchers warned that this incident could have far-reaching implications for many prominent brands utilizing the platform. The data retrieved included cookies, which, if exploited, could facilitate account takeovers, in addition to other backend system data relevant to customers. The timestamps within these logs detailed specific events and interactions, and unique identifiers linked to numerous significant companies may further exacerbate the risks involved.
Given the depth of information available on the compromised server, it is evident that a comprehensive logging and monitoring system was in place, capturing every interaction from users and applications. These logs provided an extensive overview of user behaviors and system functionalities, underscoring potential exploitation avenues.
The Cybernews team expressed their continued efforts to engage with Reputation.com for clarification and remediation. However, their attempts to establish contact have not yielded any substantial response. As it stands, the database remains unsecured, posing a substantial threat to hundreds of renowned brands, including Fortune 500 companies like US Bank and Ford.
This incident can be aligned with various tactics outlined in the MITRE ATT&CK framework. The potential methods of initial access may include untracked legacy systems or lack of proper credential management. Once inside, the adversaries could employ strategies for persistence and privilege escalation, taking advantage of the extensive logs to facilitate their operations and enhance their access to sensitive data.
Businesses leveraging the services of Reputation.com must urgently assess their cybersecurity postures and engage in proactive measures to safeguard sensitive information. The implications of this breach extend beyond immediate data vulnerability and highlight the critical need for stringent security protocols in the ever-evolving landscape of cyber threats.
