The incident score before the incident was 740 and after the incident was 740 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 Cox Enterprises and their customers.

CrowdStrike recently reported "CrowdStrike Insider Threat Incident", a noteworthy cybersecurity incident.

CrowdStrike confirmed that an insider shared screenshots taken on internal systems.

The disruption is felt across the environment, and exposing Internal screenshots (no customer data).

In response, teams activated the incident response plan, and stakeholders are being briefed through Public disclosure emphasizing no customer data compromise.

The case underscores how Confirmed (insider incident), with advisories going out to stakeholders covering No customer data compromised.

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 Trusted Relationship (T1199) with moderate to high confidence (85%), supported by evidence indicating insider shared screenshots taken on internal systems (authorized internal access). Under the Collection tactic, the analysis identified Screen Capture (T1113) with high confidence (95%), with evidence including insider shared screenshots taken on internal systems, and file types exposed such as Screenshots. Under the Exfiltration tactic, the analysis identified Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (80%), supported by evidence indicating data exfiltration such as true (screenshots shared externally, method unspecified). Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (70%), supported by evidence indicating no forensic details provided, but insider likely deleted or obscured evidence post-exfiltration. Under the Impact tactic, the analysis identified Internal Spearphishing (T1534) with moderate confidence (60%), supported by evidence indicating potential reputational risk due to insider incident (screenshots could enable follow-on social engineering). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
