CrowdStrike Breach Incident Score: Analysis & Impact (SOPCROSYM1770623613)

In this Rankiteo incident briefing, we review the CrowdStrike breach identified under incident ID SOPCROSYM1770623613.

The analysis begins with a detailed overview of CrowdStrike's information like the linkedin page: https://www.linkedin.com/company/crowdstrike, the number of followers: 977461, the industry type: Computer and Network Security and the number of employees: 10946 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 725 and after the incident was 661 with a difference of -64 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 CrowdStrike and their customers.

A newly reported cybersecurity incident, "Black Basta Ransomware Adopts New 'All-in-One' Attack Tactic with Embedded BYOVD Exploit", has drawn attention.

The Black Basta ransomware group, linked to the threat actor Cardinal, has introduced a significant evolution in its attack methodology by embedding a Bring-Your-Own-Vulnerable-Driver (BYOVD) exploit directly into its ransomware payload.

Impact assessments are still underway, so the full scope is not yet clear.

Formal response steps have not been shared publicly yet.

The case underscores how teams are taking away lessons such as BYOVD attacks remain a favored method due to reliance on legitimate, signed drivers. Integration of evasion and encryption into a single payload may set a new standard in ransomware operations.

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 confidence (50%), supported by evidence indicating prolonged dwell time (weeks before ransomware deployment). Under the Defense Evasion tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with high confidence (90%), supported by evidence indicating bYOVD exploit (CVE-2025-68947) in NsecSoft NSecKrnl driver, Impair Defenses: Disable or Modify Tools (T1562.001) with high confidence (95%), supported by evidence indicating terminate high-level security processes (Sophos, Symantec, CrowdStrike, MsMpEng.exe), Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating privileged commands executed via vulnerable driver, and Exploitation of Vulnerability (T1211) with high confidence (90%), supported by evidence indicating cVE-2025-68947 (NsecSoft NSecKrnl driver) exploited. Under the Privilege Escalation tactic, the analysis identified Exploitation for Privilege Escalation (T1068) with high confidence (90%), supported by evidence indicating bYOVD exploit (CVE-2025-68947) enables privileged command execution. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with high confidence (95%), supported by evidence indicating files encrypted with .locked extension. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating bYOVD exploit embedded in ransomware payload. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
