FBI發(fā)布安卓安全警告

Philip Elmer-DeWitt 2012-10-18
FBI警告稱,近期有大量惡意軟件在攻擊安卓系統(tǒng)的移動設(shè)備,,尤其是其中兩個惡意軟件能夠侵入用戶的設(shè)備,,竊取個人信息,,甚至遠(yuǎn)程監(jiān)控、控制設(shè)備,。惡意軟件的猖獗再次凸顯了開源開發(fā)環(huán)境的風(fēng)險(xiǎn),。

????希望讓產(chǎn)品進(jìn)入iOS App Store的軟件開發(fā)者們經(jīng)常報(bào)怨蘋果(Apple)在他們頭上強(qiáng)加了各種條條框框,不過蘋果這樣做也是有原因的,。除了要拿到30%的收入分成之外,,還有一個原因,可以從上周五美國聯(lián)邦調(diào)查局互聯(lián)網(wǎng)犯罪舉報(bào)中心(FBI’s Internet Crime Complaint Center)發(fā)布的警告中看出來,。

????警告開篇寫道:“FBI互聯(lián)網(wǎng)犯罪舉報(bào)中心了解到,,近期有大量惡意軟件在攻擊安卓(Android)系統(tǒng)的移動設(shè)備。最新為人所知的兩個此類惡意軟件叫做Loozfon和FinFisher,。

?????Loozfon是一個盜取信息的惡意軟件,。犯罪份子利用這個軟件的各種偽裝來欺騙受害者。其中一個偽裝就是提供一個在家工作的機(jī)會,,稱用戶只需在家里發(fā)發(fā)電子郵件,,就能賺到不少錢。這種虛假廣告一般都有一個鏈接,,會自動轉(zhuǎn)到一個惡意網(wǎng)站上,,將Loozfon軟件推送到用戶的設(shè)備上。該惡意應(yīng)用會從用戶的電話簿里竊取聯(lián)系信息,,同時(shí)也會偷到受感染設(shè)備的電話號碼,。

?????FinFisher是一個能控制移動設(shè)備的間諜軟件。安裝后,,無論目標(biāo)在何處,,黑客都可以通過FinFisher對該移動設(shè)備進(jìn)行遠(yuǎn)程監(jiān)控和控制,。FinFisher可以藏身在特定的網(wǎng)頁鏈接里,,也可以偽裝成一條系統(tǒng)升級短信。只要用戶點(diǎn)開它,,它就會輕而易舉地直入到智能手機(jī)里,。

????FBI給三星(Samsung)、摩托羅拉(Motorola)和HTC等運(yùn)行谷歌(Google)安卓系統(tǒng)的智能手機(jī)機(jī)主提出了以下建議:

?????購買智能手機(jī)時(shí),,要了解這款設(shè)備的功能,,包括默認(rèn)設(shè)置。盡量關(guān)閉不必要的功能,,將遭受攻擊的可能性降到最小,。

?????根據(jù)手機(jī)的類型,有些操作系統(tǒng)可以進(jìn)行加密,。手機(jī)丟失或被盜時(shí),,加密程序可以保護(hù)機(jī)主的個人信息,。

?????移動應(yīng)用日益增長,用戶們在下載應(yīng)用前應(yīng)該看看開發(fā)者或開發(fā)公司的評測文章,。

?????下載應(yīng)用的時(shí)候,,先看看需要向這個應(yīng)用開放哪些權(quán)限。

?????密碼可以保護(hù)移動設(shè)備,,它也是保護(hù)移動設(shè)備中的內(nèi)容的第一層實(shí)體堡壘,。除了使用密碼之外,還應(yīng)開啟自動鎖屏功能,,讓手機(jī)待機(jī)幾分鐘后就自動鎖屏,。

?????用惡意軟件防護(hù)程序來保護(hù)移動設(shè)備。不少專門的防護(hù)軟件都可以保設(shè)備免遭流氓程序和惡意軟件的侵害,。

?????當(dāng)心那些需要共享地理位置的應(yīng)用,,因?yàn)樗鼈儠粉櫽脩舻牡乩砦恢谩_@種應(yīng)用可能被用作營銷之用,,但也有可能用于違法活動,,比如跟蹤或盜竊。

????Developers often complain about the hoops Apple (AAPL) makes them jump through to get their wares into the iOS App Store. But the company has its reasons -- besides its 30% cut of the revenue -- and one of them was illustrated by the warningissued Friday by the FBI's Internet Crime Complaint Center (IC3).

????"The IC3 has been made aware of various malware attacking Android operating systems for mobile devices," it begins. "Some of the latest known versions of this type of malware are Loozfon and FinFisher."

?????Loozfon is an information-stealing piece of malware. Criminals use different variants to lure the victims. One version is a work-at-home opportunity that promises a profitable payday just for sending out email. A link within these advertisements leads to a website that is designed to push Loozfon on the user's device. The malicious application steals contact details from the user's address book and the infected device's phone number.

?????FinFisher is a spyware capable of taking over the components of a mobile device. When installed the mobile device can be remotely controlled and monitored no matter where the Target is located. FinFisher can be easily transmitted to a Smartphone when the user visits a specific web link or opens a text message masquerading as a system update.

????For owners of smartphones running on Google (GOOG) Android platform -- including those made by Samsung, Motorola and HTC -- the Bureau offer these safety tips:

?????When purchasing a Smartphone, know the features of the device, including the default settings. Turn off features of the device not needed to minimize the attack surface of the device.

?????Depending on the type of phone, the operating system may have encryption available. This can be used to protect the user's personal data in the case of loss or theft.

?????With the growth of the application market for mobile devices, users should look at the reviews of the developer/company who published the application.

?????Review and understand the permissions you are giving when you download applications.

?????Passcode protect your mobile device. This is the first layer of physical security to protect the contents of the device. In conjunction with the passcode, enable the screen lock feature after a few minutes of inactivity.

?????Obtain malware protection for your mobile device. Look for applications that specialize in antivirus or file integrity that helps protect your device from rogue applications and malware.

?????Be aware of applications that enable Geo-location. The application will track the user's location anywhere. This application can be used for marketing, but can be used by malicious actors raising concerns of assisting a possible stalker and/or burglaries.
