在「Tinder's Lack of Encryption Lets Strangers Spy on Your Swipes」這篇看到 Tinder 的實作問題,主要是兩個問題組合起來。第一個是圖片沒有用 HTTPS 傳輸:

On Tuesday, researchers at Tel Aviv-based app security firm Checkmarx demonstrated that Tinder still lacks basic HTTPS encryption for photos.

第二個是透過 side channel information leaking:即使是 HTTPS 傳輸,還是可以透過 size 知道是哪種類型的操作:

Tinder represents a swipe left to reject a potential date, for instance, in 278 bytes. A swipe right is represented as 374 bytes, and a match rings up at 581.

這兩個資訊就可以把行為組出來了。

接下來應該會先把圖片上 HTTPS 吧?然後再來是把各種類型的 packet 都塞大包一點?
