Nexpublica Breach Incident Score: Analysis & Impact (NEX1767101592)

In this Rankiteo incident briefing, we review the Nexpublica breach identified under incident ID NEX1767101592.

The analysis begins with a detailed overview of Nexpublica's information like the linkedin page: https://www.linkedin.com/company/nexpublica, the number of followers: 23160, the industry type: Software Development and the number of employees: 511 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 755 and after the incident was 652 with a difference of -103 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 Nexpublica and their customers.

On 22 December 2022, Nexpublica France disclosed Data Breach issues under the banner "Nexpublica Data Breach Due to Poor Cybersecurity Practices".

In November 2022, users of a Nexpublica portal reported they could access documents about third parties.

The disruption is felt across the environment, affecting Nexpublica portal, and exposing True, plus an estimated financial loss of €1.7 million ($2 million).

Formal response steps have not been shared publicly yet.

The case underscores how Completed, teams are taking away lessons such as Lack of basic security principles can lead to significant financial and reputational damage, and recommending next steps like Implement robust data security programs, adhere to regulatory requirements, and ensure proper access controls.

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 Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating users of Nexpublica’s portal discovered they could access sensitive third-party documents and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating inadequate data security program allowed unauthorized access to documents. Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate to high confidence (80%), supported by evidence indicating lack of basic security principles, failing to meet cybersecurity standards. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate confidence (50%), supported by evidence indicating users could access sensitive third-party documents (implied unauthorized access). Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating inadequate data security program, lack of fundamental security knowledge. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
