What our analysis found

sprint.youtube - Ускорение YouTube, used by 60,000 people, showed no malicious code in Extension Auditor's review. Our code review reported 1 finding (1 high), led by other. It comes from a trusted publisher and was last updated in February 2026.

Key findings

High
Other
The bundled manifest does not include [domain withheld] and [domain withheld] that appear in the published manifest summary from the Chrome Web Store listing. Conversely, the bundled manifest includes [domain withheld] and [domain withheld] which are not in the published summary. This mismatch in host_permissions between the bundled version and the live CWS listing may indicate that the permissions were changed after publication, which is a security concern.

Analyst notes

The extension appears to be a legitimate YouTube speed booster that uses proxy and VPN techniques. The ML risk score is low (0.00), the publisher is trusted, and user reviews indicate a functional albeit sometimes buggy extension. The core permissions (proxy, webNavigation) are necessary for its stated purpose. The extension discloses collection of PII and location in its CWS privacy settings, and its server domains ([domain withheld], [domain withheld]) align with the publisher's website. The provided source code (activation, message listener, placeholder) shows no evidence of data exfiltration or malicious behavior. The manifest mismatch between the bundled version and the published listing is a discrepancy, but the bundled version appears safer (no plain HTTP permissions).
