最近据安全公司BitDefender的数据显示，Facebook社交网站News Feed中有近20%的发帖包含恶意信息。

BitDefender指出，据Register报告Facebook网站近60%的攻击来自于具有危险性的第三方应用。其中22%是为用户查询档案窥视者的应用，15%是FarmVille等社交游戏的推介应用，11%是销售假冒伪劣商品的广告应用，而另外7%则提供平台游戏的社交互动。

以上数据来自于Facebook隐私应用SafeGo，该款软件可以帮助用户扫描账号，查找恶意内容。上个月，这家罗马尼亚公司发布的SafeGo试用版可用于扫描Facebook恶意墙帖，信息和评价等。SafeGo显示关于Facebook用户数据，最近活动和档案隐密性等资讯，同时该软件在每次进入用户信息时都会发送申请。目前SafeGo程序已被1万4000名用户下载，并扫描了近1700万份Facebook发帖。

Facebook恶意内容并非全部来源于应用，其中类似KoobFace等病毒也占恶意内容的5%。因此如果Facebook用户在碰点某些奇怪标题的帖子时，最好三思而后行。

据Register报告显示，BitDefender的数据也与其报告基本吻合。而据Websense的Facebook安全公司Defensio显示，在40%包含链接信息的Facebook更新中，10条中必有一条是导向垃圾邮件的。

关于这一报告，Facebook社交网站并未做出任何回复。

According to data from security company BitDefender, there’s harmful content behind about 20 percent of posts on a Facebook news feed.

BitDefender said about 60 percent of attacks on Facebook stem from threatening third-party apps, according to a report in the Register. About 22 percent of the offending apps claim to tell you who has been snooping on your profile, 15 percent tout extras in social games like Farmville, 11 percent offer counterfeit advertisements for a “dislike” button, and 7 percent focus on social iterations of console games like “Super Mario Brothers.”

BitDefender got the data from its SafeGo Facebook privacy app, which scans users’ accounts for malicious content. The Romanian company launched SafeGo in beta last month to scan components like wall posts, inboxes, messages, and comments for malware. SafeGo provides you with a dashboard that includes statistics, recent activities, and a privacy meter that shows the security of your profile. It also asks permission before accessing any of your information. The program has been downloaded by about 14,000 users and has scanned more than 17 million posts on Facebook, the Register said.

Malware on Facebook doesn’t just originate in apps; viruses like Koobface account for close to 5 percent of threats. So next time you spot a wall post that says “You’ll never believe what this guy’s cheating girlfriend did,” you might want to think twice before clicking the link.

The Register report said BitDefender’s stats are pretty consistent. Information from Websense’s Facebook security tool Defensio suggests that of the 40 percent of status updates that contain a Web link, about one in 10 lead to spam.

Facebook did not immediately respond to a request for comment. （Source：Pcmag）
