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 734 and after the incident was 619 with a difference of -115 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 InfraShield and their customers.
On 01 September 2025, a cybersecurity incident called "New Yurei Ransomware Campaign Leverages *Stranger Things*-Themed Tools in Aggressive Extortion Attacks" came to light.
Researchers at Team Cymru have uncovered a sophisticated extortion campaign tied to the Yurei ransomware toolkit, operated by a threat group first observed in September 2025.
Impact assessments are still underway, so the full scope is not yet clear.
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.
