Python 會必須先比較完整的 `stanleyjobso`（在 `stanleyjobsox` 與 `stanleyjobson` 之中都一樣），才會發現兩個字串不同。因此回覆「Incorrect username or password」會多花一些微秒。

#### 回應時間幫了攻擊者 { #the-time-to-answer-helps-the-attackers }

此時，透過觀察伺服器回覆「Incorrect username or password」多花了幾個微秒，攻擊者就知道他們有某些地方猜對了，前幾個字母是正確的。

接著他們會再嘗試，知道它更可能接近 `stanleyjobsox` 而不是 `johndoe`。
