臉書頻現網絡安全隱患似乎已經算不上是大新聞了，不過最近網友爆料的有關攝像頭的bug還是讓不少人擔心起來。

Recently, several Facebook users noticed the app is opening the camera while they're scrolling through their feeds. Many of them took to platforms like Twitter and Reddit to report their findings.
最近，多名臉書用戶注意到，當他們使用app時，攝像頭被啟動了。很多人在推特和Reddit等平臺上爆料了。
A common description of the problem seems to be that the app opens up the camera mode while users watch videos or are looking at the newsfeed. Some experience the issue when they switch to fullscreen mode, which seems to call the camera view on the screen for a brief moment.
這一問題最常見的情形是，當用戶觀看視頻或查看新聞提要時，該應用程式會打開相機模式。一些人在切換到全屏模式時遇到這個問題，屏幕上會短暫地出現相機視圖。

最早爆料這個問題的是一個網頁設計公司的負責人Joshua Maddux。發布的視頻顯示，他點開了一個用戶的頭像，然後在關閉的時候發現後置攝像頭啟動了。發現臉書一個安全和隱私的問題。使用App期間它會積極調用攝像頭。我在App裡發現一個bug，在你瀏覽時還能看到攝像頭也在開著。注意，我的鏡頭對著地毯。
視頻在這裡：
Thanks for pointing that out. Can also confirm on my phone. Seems like a bug but equally, I』ve seen the ads sometimes be tailored to things I』ve said rather than having searched for / looked at. If camera and mic are live that would explain that.
謝謝你的爆料。我手機上一樣。看起來是個bug，不過同時，我發現我這兒的廣告有時是根據我說過的東西量身定製的，而不是搜索或看過的。要是攝像頭和麥克風都開著，就能說得通了。
I noticed mine doing it too.... I turned off access to the camera but I may have to delete the app. This is creepy
我注意到我手機上也是這樣...我關了訪問攝像頭的權限，但可能還是得刪掉它。這真的太恐怖了。
Maddux進一步提醒道，說不定前置攝像頭也被悄悄啟動了。It's how @facebook accesses your camera and microphone... This is proof that they are accessing your back camera. They may also be accessing the front camera. If they process that through a facial recognition they could see your actual reaction to posts.
@Facebook就是這樣訪問你們相機和麥克風的。這只是他們正在訪問後置攝像頭的證據。他們可能也在訪問前置攝像頭。如果用面部識別技術處理一下(前置攝像頭)獲取到的信息，他們就可以看到你對帖子的實際反應。
有網友說想測一下自己手機上的臉書有沒有這個漏洞，突然意識到已經很久不用它了。I was going to try this for myself but then I remembered that I don’t use the app anymore.
我剛想自己測一下，又想起來我早都不用這個app了。
不過有工程師成功復現並證實了這個漏洞。
Jerry Gamblin, principal security engineer at Kenna Security, was able to replicate the bug and told CNN "there is no indication that the data actually is transmitted to Facebook."
肯納安保公司的首席安全工程師傑裡·甘布林復現了這個漏洞，不過他向CNN表示：「沒有跡象表明這些數據實際上被傳輸給了臉書。」
Until the fix is officially approved, Gamblin recommends that users revoke camera access for the Facebook app until an update is available.
但他仍建議，在漏洞完全修復、App有可用更新之前，用戶最好取消臉書的攝像頭訪問權限。

自2018年3月，「劍橋分析醜聞」曝出以來，臉書就似乎進入了水逆期。頻發的隱私問題引起不少網友詬病，甚至還一度引發#DeleteFacebook(刪除臉書)的話題。所以，對於新出現的bug，網友已經見怪不怪了。umm thats not a bug thats a feature if u ask FB
umm，如果你問臉書，他們會回應說這不是一個bug，是我們的特色。
FB is cancer.
臉書就是個毒瘤。
這次，臉書方面倒是爽快地承認了這個bug。負責產品管理的副總裁蓋伊·羅森在回帖中表示公司已對此展開調查。Thanks for flagging this. This sounds like a bug, we are looking into it.
謝謝提交這個信息。聽起來確實像是個bug，我們正在調查中。
之後，他又確認已經向蘋果商店提交了新版App，並強調沒有發現這個漏洞會導致照片或視頻在後臺上傳的證據。但是，也有一些用戶認為，這可能是蘋果系統的漏洞，因為他們在推特、Instagram等其他app上也發現了類似問題。Now that you mention it, I think it's an Apple issue because it has happened to me before on other apps.
既然你提到了這一點，我認為這是蘋果的問題，因為之前我在其他App上也遇到過這種情況。
