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 663 and after the incident was 658 with a difference of -5 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 TP-Link Systems Inc. and their customers.
Microsoft recently reported "Cybersecurity Roundup: Zero-Days, AI Threats, and Massive Exploits Dominate July 2026", a noteworthy cybersecurity incident.
This week’s cybersecurity landscape underscored the relentless expansion of attack surfaces, with high-impact vulnerabilities, active exploits, and emerging threats targeting everything from enterprise identity systems to AI-driven workflows.
The disruption is felt across the environment, affecting SharePoint Server, Active Directory Federation Services and WordPress sites, and exposing Client tax and investment documents, Browsing history and Admin passwords.
In response, and began remediation that includes Patches released by Microsoft, WordPress, Notepad++, Dell, Fortinet, F5, Splunk.
Overall, the incident is a reminder of why proactive monitoring and strong governance matter.
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.
