In a recent development that highlights the ever-evolving nature of cybersecurity threats, Gainsight has disclosed that its recent suspicious activity targeting applications has affected more customers than previously thought. The breach was claimed by notorious cybercrime group ShinyHunters (aka Bling Libra) and prompted Salesforce to revoke access and refresh tokens associated with Gainsight-published applications connected to the platform.
Gainsight, a cloud-based software company, had initially disclosed that only 3 customers were affected but has since expanded the list of impacted customers. According to the company's CEO, Chuck Ganapathi, "we presently know of only a handful of customers who had their data affected." However, this revelation contradicts the initial statement, sparking concerns about the company's transparency and incident response.
The breach is linked to a security flaw in Salesforce, which allows attackers to impersonate users and escalate privileges. The vulnerability, identified as CVSS 10.0 SCIM Flaw, enables ShinyHunters to gain unauthorized access to sensitive information and manipulate system operations. This flaw has been classified as High on the Common Vulnerability Scoring System (CVSS), indicating that it poses a significant risk to organizations using Gainsight's services.
In addition to the data breach, Salesforce has also issued indicators of compromise (IoCs) associated with the ShinyHunters group. These IoCs include user agent strings and IP addresses used for reconnaissance efforts against customers with compromised Gainsight access tokens.
Gainsight has taken steps to secure its environment by advising affected customers to rotate S3 bucket access keys, log in directly through Gainsight NXT rather than using Salesforce integrations, reset NXT user passwords, and re-authorize connected applications or integrations that rely on user credentials or tokens. These measures are designed to mitigate the impact of the breach and prevent further unauthorized access.
The ShinyHunters group has been linked to at least 51 cyberattacks over the past year, according to data from ZeroFox. The group's ransomware-as-a-service (RaaS) platform, ShinySp1d3r, boasts features that set it apart from other RaaS platforms. These features include the ability to prevent Windows Event Viewer logging, terminate processes that keep files open, and fill free space in a drive by writing random data contained in a .tmp file.
Furthermore, ShinySp1d3r allows users to search for open network shares and encrypt them, as well as propagate to other devices on the local network through deployViaSCM, deployViaWMI, and attemptGPODeployment. This highlights the group's sophistication and willingness to adapt their tactics to evade detection.
The incident serves as a stark reminder of the importance of cybersecurity awareness and incident response planning. As organizations continue to rely on cloud-based services, it is crucial that they prioritize robust security measures and stay vigilant against emerging threats.
In light of this breach, Gainsight has emphasized its commitment to customer safety and has taken proactive steps to address the issue. However, the incident also underscores the need for greater transparency and communication from companies in the event of a data breach.
In conclusion, the recent data breach at Gainsight highlights the ever-evolving nature of cybersecurity threats and the importance of robust security measures. As organizations continue to navigate the complex landscape of cloud-based services, it is crucial that they prioritize incident response planning, cybersecurity awareness, and transparency to mitigate the impact of such incidents.
