Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Nikkei Asia breach identified under incident ID NIK1776752855.
The analysis begins with a detailed overview of Nikkei Asia's information like the linkedin page: https://www.linkedin.com/company/nikkeiasia, the number of followers: 763516, the industry type: Newspaper Publishing and the number of employees: 428 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 723 and after the incident was 469 with a difference of -254 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 Nikkei Asia and their customers.
A newly reported cybersecurity incident, "Over 200 Japanese Firms Paid Ransomware Attackers; Most Failed to Recover Data", has drawn attention.
A recent survey by the Japan Institute for Promotion of Digital Economy and Community reveals that ransomware attacks have severely impacted Japanese businesses, with 507 of 1,107 responding firms reporting incidents.
The disruption is felt across the environment, and exposing Data encryption and potential data exfiltration, plus an estimated financial loss of ['1 million yen - 50 million yen ($6,300 - $315,000) for 50% of affected businesses', 'Exceeding 1 billion yen for 4.3% of affected businesses', 'Minimal or no financial impact for 16%'].
In response, while recovery efforts such as 141 firms recovered systems without paying ransom continue.
The case underscores how teams are taking away lessons such as Paying ransoms does not guarantee data recovery and may further fund criminal 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.
