Is CookieCloud safe?

Medium risk

CookieCloud reads all browser cookies and uploads an encrypted copy to a third-party server every 10 minutes.

Once a sync password is set, CookieCloud reads every cookie in the browser (and optionally per-domain localStorage), encrypts the data, and automatically uploads it on a timer to ccc.ft07.com by default. The encryption key is derived from a single unsalted MD5 hash of the user's uuid and password, and an optional mode uses a fixed all-zero IV, both of which weaken the protection on the uploaded cookie and session data if the ciphertext is intercepted or the endpoint is compromised.

Where it sends data

Destinations our analysis observed CookieCloud contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
