Context-Aware Verdict
This section provides a Claude-based AI analysis that applies additional context to the risk. Results are not guaranteed to be accurate.
HIGH
Risk Level
Trust Factors:
- The extension has a relatively high number of users (90,000) and a good rating (4.8/5), which suggests some level of trust from the user community.
- However, the developer information is limited, and there is no clear indication of a reputable company behind the extension.
Concerns:
- The extension requests several high-risk permissions, including tabs, webRequest, downloads, and broad host permissions (<all_urls>), which could potentially be abused for malicious purposes.
- The ability to inject content scripts into any website raises concerns about potential privacy violations and data theft.
- The broad permissions granted to the extension seem excessive for its stated purpose of downloading videos, which could indicate potential malicious intent or functionality.
Recommendations:
- Exercise caution when installing this extension, as the high-risk permissions and broad access could potentially compromise your security and privacy.
- Consider using the extension in a separate browser profile or a sandboxed environment to mitigate potential risks.
- Regularly monitor the extension's behavior and permissions, and uninstall it if any suspicious activity is detected.
- Look for alternative video downloading extensions from more reputable sources that request fewer permissions and have better transparency regarding their functionality and data handling practices.
