Crisis24 Breach Incident Score: Analysis & Impact (CRI1092110112625)

In this Rankiteo incident briefing, we review the Crisis24 breach identified under incident ID CRI1092110112625.

The analysis begins with a detailed overview of Crisis24's information like the linkedin page: https://www.linkedin.com/company/gardaworld-crisis24, the number of followers: 71897, the industry type: Security and Investigations and the number of employees: 2157 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 758 and after the incident was 758 with a difference of 0 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 Crisis24 and their customers.

On 24 November 2023, Crisis24 (OnSolve) disclosed ransomware and data breach issues under the banner "Cyberattack on OnSolve CodeRED Emergency Alert System by INC Ransomware Group".

Crisis24’s OnSolve CodeRED emergency alert system was disrupted by a cyberattack attributed to the INC ransomware group.

The disruption is felt across the environment, affecting OnSolve CodeRED emergency alert system, and exposing names, addresses and email addresses.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like decommissioning of compromised OnSolve CodeRED platform and transition to new, non-compromised CodeRED environment, and began remediation that includes comprehensive security audit, external penetration testing and system hardening, while recovery efforts such as rollout of new CodeRED platform (expected by 2023-11-28 for some entities) and use of alternative alert methods (e.g., IPAWS, social media, door-to-door notifications) continue, and stakeholders are being briefed through public statements by affected local governments, advisories to change passwords for other accounts if reused and updates via local media, websites, and social media.

The case underscores how Ongoing (transition to new platform; no details on forensic investigation), with advisories going out to stakeholders covering Urged users to change passwords for other accounts if the same password was reused.

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 (T1078) with moderate to high confidence (70%), supported by evidence indicating initial access gained on November 1 (no specific vector, but ransomware often leverages compromised credentials) and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating onSolve CodeRED emergency alert system was disrupted by a cyberattack (public-facing system likely targeted). 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 exposure of ... passwords in exfiltrated CSV files (~1.15 TB data) and OS Credential Dumping (T1003) with moderate to high confidence (70%), supported by evidence indicating ransomware group encrypted the network (common post-exploitation after credential access). Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with high confidence (95%), supported by evidence indicating exfiltrated ~1.15 TB of data including CSV files with client-related data and Automated Exfiltration (T1020) with moderate to high confidence (80%), supported by evidence indicating large-scale (~1.15 TB) exfiltration suggests automated tools/scripts. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (100%), with evidence including network encryption on 2023-11-10 by INC Ransomware, and disrupted critical emergency communication services and Data Destruction (T1485) with moderate to high confidence (70%), supported by evidence indicating decommissioning of compromised OnSolve CodeRED platform (implies potential corruption/destruction). Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (75%), supported by evidence indicating ransomware group encrypted the network (often preceded by deletion of logs/backups) and Impair Defenses: Disable/Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating ransomware operations typically disable security tools pre-encryption. Under the Persistence tactic, the analysis identified Valid Accounts: Local Accounts (T1078.003) with moderate to high confidence (70%), supported by evidence indicating 9-day dwell time (Nov 1–10) suggests persistence mechanisms (e.g., backdoor accounts). Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating exfiltrated ~1.15 TB of data including PII/CSV files from CodeRED systems. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate confidence (60%), supported by evidence indicating ransomware often uses RDP for internal movement; 9-day dwell time implies lateral spread. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
