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 331 and after the incident was 310 with a difference of -21 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 Microsoft Security and their customers.

Microsoft recently reported "Microsoft Edge Password Manager Flaw Exposes Credentials in Plain Text", a noteworthy cybersecurity incident.

A critical vulnerability in Microsoft Edge’s built-in Password Manager was discovered, where saved credentials remain exposed in plain text within the browser’s process memory even after the browser is closed and reopened.

The disruption is felt across the environment, affecting Microsoft Edge browser on all devices, and exposing User credentials.

In response, and stakeholders are being briefed through Dismissed as 'by design'.

The case underscores how Publicly disclosed, no resolution from Microsoft, teams are taking away lessons such as Browser-based password managers require stronger security measures, such as App Bound Encryption, to prevent plain text credential exposure. Enterprise environments are particularly vulnerable to such flaws, and recommending next steps like Microsoft should implement App Bound Encryption or similar protections for Edge’s Password Manager, Users should avoid storing sensitive credentials in browser-based password managers until the issue is resolved and Organizations should assess the risks of using Edge in enterprise environments and consider alternative browsers with stronger security controls, with advisories going out to stakeholders covering Microsoft has dismissed the issue as 'by design.' Cybersecurity experts advise caution in using Edge’s Password Manager.

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.
