In this Rankiteo incident briefing, we review the US Navy breach identified under incident ID US-1768809333.

The analysis begins with a detailed overview of US Navy's information like the linkedin page: https://www.linkedin.com/company/us-navy, the number of followers: 716064, the industry type: Armed Forces and the number of employees: 161815 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 809 and after the incident was 767 with a difference of -42 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 US Navy and their customers.

Microsoft recently reported "Mandiant Exposes Net-NTLMv1 Vulnerabilities, Espionage Sentencing, and Cybercrime Arrests", a noteworthy cybersecurity incident.

Google’s Mandiant released tools to demonstrate vulnerabilities in Microsoft’s Net-NTLMv1 authentication protocol, a US Navy sailor was sentenced for selling secrets to China, a hacker pleaded guilty to accessing the US Supreme Court’s filing system, Interpol arrested members...

The disruption is felt across the environment, affecting Microsoft Net-NTLMv1 Authentication Protocol and US Supreme Court’s electronic filing system, and exposing Classified technical manuals, Operational intelligence and Supreme Court electronic filings.

In response, moved swiftly to contain the threat with measures like Disabling Net-NTLMv1 protocol.

The case underscores how Ongoing, teams are taking away lessons such as Organizations should disable outdated and vulnerable protocols like Net-NTLMv1 immediately to prevent credential theft. Insider threats and unauthorized access to sensitive systems pose significant risks to national security and judicial integrity, and recommending next steps like Disable Net-NTLMv1 protocol, Enhance monitoring of insider threats and Strengthen access controls for sensitive systems.

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 high confidence (90%), supported by evidence indicating uS Navy sailor...selling classified technical manuals and operational intelligence and Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating net-NTLMv1 authentication protocol...vulnerable to credential theft. Under the Credential Access tactic, the analysis identified Password Cracking (T1110.002) with high confidence (95%), supported by evidence indicating mandiant released rainbow tables capable of cracking Net-NTLMv1 in under 12 hours and Steal or Forge Kerberos Tickets: Kerberoasting (T1558.003) with moderate confidence (60%), supported by evidence indicating net-NTLMv1...known for over 20 years to be vulnerable to credential theft. Under the Lateral Movement tactic, the analysis identified Exploitation of Remote Services (T1210) with moderate to high confidence (70%), supported by evidence indicating net-NTLMv1 remains in use despite repeated warnings. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating classified technical manuals and operational intelligence compromised and Data from Information Repositories (T1213) with moderate to high confidence (80%), supported by evidence indicating supreme Court’s electronic filing system accessed illegally. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating wei earned $12,000 from selling classified technical manuals to China and Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (70%), supported by evidence indicating data exfiltration of classified technical manuals and operational intelligence. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating uS Navy sailor used legitimate access to sell secrets and Code Signing: Code Signing Policy Modification (T1553.002) with moderate confidence (50%), supported by evidence indicating legacy protocol exploitation (Net-NTLMv1) evades modern security controls. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (40%), supported by evidence indicating no details on extent of breach for Supreme Court filings and Defacement (T1491) with lower confidence (30%), supported by evidence indicating brand reputation impact for US Navy, Supreme Court, Interpol. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
