Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the VICCHEM breach identified under incident ID VIC1772195353.
The analysis begins with a detailed overview of VICCHEM's information like the linkedin page: https://www.linkedin.com/company/vicchem, the number of followers: 1017, the industry type: Chemical Manufacturing and the number of employees: 38 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 752 and after the incident was 634 with a difference of -118 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 VICCHEM and their customers.
On 23 October 2023, Vicchem (Victorian Chemical Company) disclosed Ransomware issues under the banner "RansomHouse Claims Breach of Australian Chemical Manufacturer Vicchem".
On 23 October, the ransomware group RansomHouse listed Vicchem, a Coolaroo-based manufacturer of industrial and agricultural chemicals, also known as the Victorian Chemical Company, on its darknet leak site.
The disruption is felt across the environment, and exposing Employee passport scans, invoices, banking documents, budget reports, payroll records.
Formal response steps have not been shared publicly yet.
The case underscores how Ongoing.
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.
