Couples sex video chat, third eye looking at carefully-privacy and information security-IT information

Wang: Baby, long time no see you, Miss you, Oh!

Alice: well, our videos, and Yao Yao da

LDR couples love Wang and little red open a video chat software on your computer, never thought that their sweet talk and video are seen clearly by third through malware!

Nani? Baby scared to edit, this is not a joke, is really possible!

When opened you can rest assured that some seemingly safe, legitimate applications software, such as FaceTime, chat, Skype, Google ring, who would have thought of malicious software on the Mac may be by Mac computers equipped with the camera to your monitor.

And even more scary is that this malicious monitoring software won't open the camera LED lights to keep you alert .

In 2013, in one of the four global computer security conference--USENIX Conference on security, a group of experts has been demonstrated how to go unnoticed in case, for example, without physical contact, closing the MacBook's camera LED lights. However, this technique only shows on the old version of the iMac and MacBook, but newly discovered malware so this demonstrates again come true.

However, this new malware uses different mechanisms to look into, it is to open a legitimate user application software, synchronization turned on camera secretly monitored.

For example, you want to use Skype to video when the camera is turned on, the malware opportunity to wipe the oil.

Qian United States national security agency hacker, Synack Research Director patelike·wadeer (Patrick Wardle), have been trying to find a Mac laptop's vulnerability, he found some.

He saidcameras are likely to spy on the other side of the screen of the Mac users, for Mac cameras can be shared with multiple applications. When the malicious software when you open the camera, LED lights are not lit at all, I don't know someone was spying on users .

Waddell said: "if my Mac is infected, all my movements will be recorded. An attacker will see me sitting at the desk, picking your nose, touching dogs and occasionally my computer ... ... However, when jumping the previous Google link talk, talk of a new 0 vulnerabilities, things get interesting.

It is no wonder that Facebook founder Mark Zuckerberg chose to use Scotch tape over his camera and microphone.

Addiction said, no way! My webcam and microphone, how am I going to live? There is no other way?

Really there! In order to prevent these, Waddell has designed a monitoring tool for OverSight, where there is an application you want to open the camera, it will request permission to Mac users, users will have the right to refuse or to receive this visit. For example, when there is a software to open the camera, the tool displays what applications trying to get audio and video permissions so users can decide to let the security software to prevent malicious applications.

As shown in the figure :

In addition, the tool will download the latest Mac OS x software records user default log permission, and they tried to alert users when suspicious website and download the application.

情侣亲热视频聊天，小心第三只眼在偷看 - 隐私,信息安全 - IT资讯

小王：Baby，好久没看到你了，好想你哦!

小红：嗯，我们视频吧，么么哒

热恋异地恋情侣小王和小红打开了电脑上某聊天软件视频，未曾想到，他们的甜蜜聊天与视频正被第三个人通过恶意软件看得一清二楚！

纳尼？吓死编辑宝宝了，这次不是段子，是真的有可能发生！

当你放心地打开一些看似安全、合法的应用软件时，如FaceTime,、Skype、Google环聊，谁曾想到Mac上的恶意软件可能正通过Mac电脑上搭载的摄像头对你实行监控。

而且更让人怕怕的是，这种恶意监视软件是不会打开摄像头的LED灯让你有所警觉的。

2013年，在全球计算机安全四大会议之一——USENIX安全大会上，一群专家已经演示过如何在神不知鬼不觉地情况下，例如，无需物理接触，关闭MacBook的摄像头LED灯。但是，当时这项技术仅在老版的iMac和MacBook上演示，没想到最新发现的恶意软件让这一演示再度成真。

不过，这种新恶意软件利用的是不同机制来窥视，它是在用户打开合法的应用软件后，同步开启摄像头偷偷监视。

比如，你本来就想用Skype来视频，在打开摄像头时，这个恶意软件趁机揩了一把油。

前美国国家安全局黑客，现Synack研究部主任帕特里克·瓦德尔（Patrick Wardle），一直在尝试寻找Mac笔记本的漏洞，他对此也有一些发现。

他说，Mac的摄像头很可能窥探屏幕另一边的用户，因为Mac摄像头可与多个应用程序共享。当上述恶意软件打开摄像头时，LED灯压根就不亮，鬼才知道有人在监视用户。

瓦德尔说：“如果我的Mac受到感染，我的一切行踪将被记录。攻击者会看到我坐在书桌前，挖鼻孔、抚摸狗狗、偶尔骂我的电脑……然而，当跳上一个谷歌环聊，与对方讨论一个新的零日漏洞，事情就有趣了。

无怪乎Facebook创始人马克·扎克伯格选择用透明胶带遮住他的摄像头和麦克风。

网瘾群众表示，不行！封了我的摄像头和麦克风我要怎么活？有没有别的办法？

还真有！为了防止这些，瓦德尔设计了一个监督工具OverSight，凡是有应用程序想要打开摄像头，它都会向Mac用户请求权限，用户将有权拒绝或接收此访问。例如，当有软件想打开摄像头时，该工具会显示有哪些应用在试图获取音频、视频权限，从而用户可以决定放过安全软件，阻止恶意应用。

如图所示：

另外，该工具将随着下载最新的Mac OS X软件记录用户默许的日志权限，并在它们试图从可疑网站下载应用程序时警醒用户。
