Context-Aware Verdict

CRITICAL
Overall Risk
Trust Factors: The extension has a moderate user base of 20,000 users and a decent rating of 4.3 stars from 89 reviews, which suggests some level of user satisfaction. However, the lack of clear developer information and company details reduces trustworthiness. Video downloaders are inherently risky as they often require extensive permissions to function across various video platforms.
Concerns: This extension exhibits multiple red flags that justify the critical risk rating. The combination of broad host permissions with content script injection capabilities creates a dangerous attack surface, allowing the extension to access and manipulate data on every website you visit. The webRequest permission enables traffic interception, which could be exploited for credential theft or data exfiltration. The unsafe WebAssembly execution policy is particularly concerning as it allows potentially obfuscated malicious code to run. The downloads permission, while necessary for the extension's function, adds another vector for potential abuse.
Recommendations: Given the critical risk level, avoid installing this extension on your primary browser profile. If you must use it, create a dedicated Chrome profile specifically for video downloading activities, ensuring no sensitive accounts are logged in. Consider using established, well-reviewed alternatives from reputable developers. Monitor your download folder for unexpected files and regularly review the extension's network activity. Be extremely cautious about using this extension on websites where you handle sensitive information like banking or personal accounts.
