Major International Stock Exchange recently reported "Mass Exposure of Sensitive Credentials via Online Code Formatting Tools", a noteworthy cybersecurity incident.

Developers are inadvertently exposing sensitive credentials, API keys, and passwords by using popular online code formatting tools (JSONFormatter and CodeBeautify).

The disruption is felt across the environment, affecting Splunk SOAR Automation (Major International Stock Exchange), Active Directory (MSSP & U.S. Bank) and Unknown Systems (Government, Cybersecurity, Financial Sectors), and exposing API Keys, AWS Credentials and Active Directory Credentials, with nearly Thousands (across 80,000+ submissions) records at risk.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Revoke Exposed Credentials (Recommended) and Disable Compromised API Keys (Recommended), and began remediation that includes Audit Historical Usage of Code Formatting Tools, Implement Detective Controls for Secret Exposure and Block Access to Public Code Formatting Tools (Corporate Policy), and stakeholders are being briefed through Public Advisory via watchTowr Labs and CERT Notifications.

The case underscores how Ongoing (Active Harvesting Confirmed), teams are taking away lessons such as Public code formatting tools pose significant risks for credential exposure, Developers lack awareness of permanent accessibility of 'saved' links and Critical sectors are equally vulnerable to human-error-driven leaks, and recommending next steps like Prohibit use of public code formatting tools for sensitive data, Mandate local/private alternatives (e.g., VS Code plugins, internal tools) and Implement automated secret scanning in repositories and emails, with advisories going out to stakeholders covering CERT Notifications and Sector-Specific Warnings (Finance/Government).

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.

MITRE ATT&CK® Correlation Analysis

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 production AWS credentials for its Splunk SOAR system exposed via public link, and credentials actively harvested by unknown actors with unauthorized access attempts and Gather Victim Identity Information: Credentials (T1589.002) with high confidence (90%), with evidence including 80,000+ submissions containing leaked secrets (AWS keys, AD credentials), and attackers actively monitor platforms for fresh credentials. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with high confidence (100%), with evidence including aWS credentials, AD credentials, SSH keys exposed in JSON/config files, and publicly accessible shareable links on JSONFormatter/CodeBeautify and Unsecured Credentials: Private Keys (T1552.004) with high confidence (95%), supported by evidence indicating sSH private keys and Docker credentials exposed in submissions. Under the Persistence tactic, the analysis identified Account Manipulation: Additional Cloud Credentials (T1098.003) with moderate to high confidence (85%), with evidence including compromised Splunk SOAR AWS credentials could enable privilege escalation, and potential to disrupt automated security operations. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (80%), with evidence including compromising Splunk SOAR could manipulate threat detection, and disrupt automated security operations. Under the Impact tactic, the analysis identified Endpoint Denial of Service: Service Exhaustion Flood (T1499.002) with moderate to high confidence (75%), supported by evidence indicating potential for large-scale operational disruptions in financial infrastructure and Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating risks to incident response capabilities could enable follow-on attacks. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), with evidence including confirmed harvesting of credentials by unknown actors, and data sold on dark web likely (given active harvesting). Under the Reconnaissance tactic, the analysis identified Gather Victim Host Information (T1592) with moderate to high confidence (85%), with evidence including attackers monitor Recent Links pages for 1-5 years, and high-value targets such as AWS (Splunk SOAR), AD (MSSP), KYC data and Gather Victim Network Information: Scan Victim (T1590.005) with moderate to high confidence (80%), supported by evidence indicating unauthorized access attempts detected post-link expiry. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
