System Update #117: Security & Privacy Implications - Microsoft's Copilot Windows 'Recall' Feature

Security and Privacy Implications of Microsoft's Copilot for Windows 'Recall' Feature

The introduction of Microsoft's new Recall feature in Copilot for Windows has generated significant concern around security and privacy. Designed to take regular screenshots of user activity, this feature aims to create an index that can be queried using AI. However, the lack of an option to disable the feature during setup has raised alarms about the potential for misuse and unauthorized access to sensitive information.

Cybersecurity experts have labeled the feature a "security nightmare," warning that continual recording of user devices could make Copilot PCs a prime target for cybercriminals. Documents, emails, and other personal data captured via screenshots could be exploited if not properly secured.

This feature captures screenshots of a user's screen every few seconds. These activities include apps, documents, and websites accessed on their device. Recall's Timeline Search allows users to search through their past activity using various clues or the timeline.

Concerns have emerged about privacy and security, as the feature is automatically enabled on new Copilot+ PCs without an option to disable it during setup.

I've put together three takeaways and next steps:
1. Core Functionality
Windows Recall captures screenshots and uses Optical Character Recognition (OCR) to extract text and other data from the screen. This processed information is then stored locally or sent to the cloud for further analysis.

The feature's implementation requires continuous monitoring of the screen, thereby increasing the complexity and scope of data it handles. This method demands robust algorithms to ensure accurate text recognition and data extraction, minimizing false positives and errors.

2. Potential Vulnerabilities
One area of concern is the possibility of zero-day exploits—unknown vulnerabilities that could be targeted by malicious actors. That is to say that now malware knows exactly what data to target for exfiltration once it is installed on your computer. And since Recall uses impressive levels of data compression, it wont take more than a few minutes to exfiltrate all of your data and screenshots of everything you've done on your computer since the time this feature was enabled.

3. Privacy Considerations
Recall raises several important privacy issues. These include the collection and use of user data, the control over privacy settings, sharing data with third parties, and ensuring compliance with privacy laws.

For instance, Recall collects a significant amount of user data. Every few seconds, it takes screenshots and stores them. This includes sensitive information that users consider private. And this data will be shared with third parties under certain conditions. Which raises concerns about who has access to the data and for what purposes.
