In this Rankiteo incident briefing, we review the LockNet breach identified under incident ID LOC1765418784.

The analysis begins with a detailed overview of LockNet's information like the linkedin page: https://www.linkedin.com/company/locknet, the number of followers: 1432, the industry type: Facilities Services and the number of employees: 131 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 759 and after the incident was 693 with a difference of -66 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 LockNet and their customers.

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 unauthorized access to its IT network detected on August 2, 2025 and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating unauthorized third party accessed sensitive data (no specific vector mentioned). Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate confidence (60%), supported by evidence indicating unauthorized access to IT network implies possible credential compromise. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating sensitive personal identifiable information (names, Social Security numbers) compromised and Automated Exfiltration (T1020) with moderate confidence (60%), supported by evidence indicating data breach with high sensitivity of data (no encryption mentioned). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating no evidence of ransomware or encryption, but high-impact data breach and Data Manipulation: Stored Data Manipulation (T1565.001) with lower confidence (40%), supported by evidence indicating unauthorized access to sensitive data implies potential manipulation risk. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
