Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Cisco breach identified under incident ID CISSONMICORAASYKNX1784341544.
The analysis begins with a detailed overview of Cisco's information like the linkedin page: https://www.linkedin.com/company/cisco, the number of followers: 7652581, the industry type: Software Development and the number of employees: 95930 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 189 and after the incident was 187 with a difference of -2 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 Cisco and their customers.
Lidl recently reported "Cybersecurity Roundup: Critical Vulnerabilities, Supply Chain Attacks, and Major Breaches", a noteworthy cybersecurity incident.
A compilation of recent cybersecurity incidents including critical vulnerabilities, supply chain attacks, data breaches, ransomware, and state-backed cyber campaigns.
The disruption is felt across the environment, affecting Nihon Kotsu taxi services, Nichirei food company systems and Transport for London (TfL), and exposing Customer data (Lidl), Sensitive client information (EY) and Personally identifiable information (various breaches), plus an estimated financial loss of £29 million (Scattered Spider attack on TfL).
In response, and began remediation that includes Patching (Microsoft, SonicWall, Zoom) and Sanctions (U.S. Treasury).
The case underscores how and recommending next steps like Prioritize patching for known exploited vulnerabilities (CISA KEV catalog), Monitor supply chain risks (e.g., npm packages) and Enhance third-party security assessments.
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.
