The analysis begins with a detailed overview of Gainsight's information like the linkedin page: https://www.linkedin.com/company/gainsight, the number of followers: 157947, the industry type: Software Development and the number of employees: 1100 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 473 and after the incident was 349 with a difference of -124 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Gainsight and their customers.

Gainsight recently reported "Gainsight Data Breach Affecting Salesforce Customer Tokens", a noteworthy cybersecurity incident.

A limited number of Gainsight clients had their data compromised following a breach of the customer management software firm's systems, impacting Salesforce customer tokens.

The disruption is felt across the environment, affecting Salesforce instances (potentially over 200) and Gainsight Connected App, and exposing True.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like IP restrictions for API calls, and began remediation that includes Review of Salesforce logs for authentication attempts and API calls from Gainsight Connected App, and stakeholders are being briefed through Advisories issued to clients to investigate logs and implement mitigations.

The case underscores how Ongoing (customers urged to review logs; extent of breach under investigation), and recommending next steps like Review Salesforce logs for authentication attempts and API calls from Gainsight Connected App, Implement IP restrictions for API calls and Monitor for anomalous access patterns, with advisories going out to stakeholders covering Clients advised to investigate Salesforce logs and implement IP restrictions.

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (95%), with evidence including compromised Salesforce customer tokens via Gainsight Connected App, and authentication attempts and API calls originating from the Gainsight Connected App. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (85%), supported by evidence indicating salesforce customer tokens compromised in breach and Steal Application Access Token (T1528) with high confidence (95%), supported by evidence indicating compromised Salesforce customer tokens. Under the Persistence tactic, the analysis identified Office Application Startup: Add-ins (T1137.005) with moderate to high confidence (75%), supported by evidence indicating aPI calls originating from the Gainsight Connected App (abuse of trusted app integration). Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating gainsight’s own logs deemed insufficient for assessing organizational risk (possible log tampering/insufficiency) and Impair Defenses: Disable or Modify Tools (T1562.001) with moderate confidence (65%), supported by evidence indicating clients urged to rely on Salesforce-side logs (implication of compromised Gainsight logging). Under the Lateral Movement tactic, the analysis identified Remote Services: SMB/Windows Admin Shares (T1021.002) with moderate confidence (60%), supported by evidence indicating potentially affected over 200 Salesforce instances (cross-instance movement via tokens) and Remote Services: SSH (T1021.004) with moderate confidence (50%), supported by evidence indicating review Salesforce logs for ... API calls (possible SSH tunneling for API abuse). Under the Collection tactic, the analysis identified Automated Collection (T1119) with moderate to high confidence (80%), supported by evidence indicating aPI calls originating from the Gainsight Connected App (automated data harvesting). Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (85%), with evidence including data compromised via abused Connected App API calls, and review logs for anomalous access patterns (implied data transfer) and Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (70%), supported by evidence indicating iP restrictions for API calls recommended (suggests abuse of legitimate API channels). Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (30%), supported by evidence indicating data compromised (no explicit destruction, but token abuse could lead to secondary impact) and Resource Hijacking (T1496) with moderate to high confidence (75%), supported by evidence indicating abuse of Gainsight Connected App (hijacking trusted SaaS integration for malicious use). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
