據報導，在過去3個月中，
卡巴斯基實驗室的專家一直在---
--對一種被稱為Obad.a木馬的安卓惡意應用--
--的傳播手段進行調查。
調查顯示，該木馬幕後的網絡罪犯--
--使用了一種全新的感染手段對該--
--惡意軟件進行傳播。
這也是手機網絡犯罪歷史上，
首個利用其他網絡犯罪集團--
--掌控的殭屍網絡進行傳播的木馬程序。
目前，Obad在CIS(獨聯體)國家傳播最為廣泛，
其中83%的感染均發生在俄羅斯。
此外，烏克蘭、白俄羅斯、
烏茲別克斯坦和哈薩克斯坦等國家的--
--移動設備上同樣檢測到這一木馬。
調查顯示，
Obad的多種版本採用了一種有趣的傳播模式，
即利用Trojan----SMS.AndroidOS.Opfake.a進行傳播。
這種雙重感染手段一般--
--通過向用戶發送短信來進行。
短信會提示用戶下載一個最新收到的短信息。
如果受害者點擊了短信鏈接，
會自下載動一個包含Opfake的文件--
--到用戶智能手機和平板電腦。
而用戶啟動該惡意文件，
惡意程序就會安裝。
一旦其成功運行，
木馬會向被感染設備中的所有聯繫人發送短信。
如果接收到這些短信的用戶點擊其中的鏈接，
就會下載Obad.a木馬。
這是一種非常有效的傳播系統。
一家俄羅斯移動網絡供應商聲稱，
僅在5小時內，網絡內就出現超過--
--600條包含此類惡意鏈接的短信，
這表明其傳播規模非常可觀。
大多數情況下，
該惡意軟件會利用已經被感染的設備進行傳播。
除了利用手機殭屍網絡進行傳播外，
這種高度複雜的木馬還能夠--
--通過垃圾短信進行傳播。
這也是Obad.a木馬的主要傳播途徑。
通常，手機用戶會接收到一條提示用戶“欠費”的短信，
如果用戶點擊了其中的鏈接，
便會自動下載Obad.a到移動設備。
同樣地，只有用戶運行下載文件，
才會將木馬安裝到設備上。
與此同時，
一些假冒的應用商店同樣會--
--傳播Backdoor.AndroidOS.Obad.a。
這些在線應用商店會抄襲Google Play的頁面，
並將其中的合法應用鏈接替換為惡意應用鏈接。
當合法網站被黑客攻陷後，
用戶就會被重定向到惡意網站。
Obad.a僅針對移動用戶發起攻擊，
如果用戶使用家用計算機訪問惡意網站，
則什麼都不會發生。
但是如果使用移動操作系統的--
--智能手機和平板電腦訪問，
即會被重定向到假冒的惡意網站(
目前只有安卓用戶面臨感染風險)。
“3個月期間，我們共發現12種不同版本--
--的Backdoor.AndroidOS.Obad.a。
這些惡意程序全都具有相似的功能--
--以及較高水平的干擾代碼。
每個版本的惡意程序都會利用安卓操作系統的漏洞，
使得惡意軟件具備設備管理員權限，
使得清除非常困難。
發現上述情況後，
我們立即通知了Google公司。
Google已經在安卓4.3中修補了上述安全漏洞。
但是，現在只有少數最新的智能手機和--
--平板電腦運行這一版本的安卓系統，
運行較早版本安卓系統的設備仍然面臨風險。
同其他安卓木馬不同，
Obad.a使用大量未公佈的漏洞進行感染，
這一點與Windows惡意軟件非常相似，
'”卡巴斯基實驗室頂級反病毒專家Roman Unuchek解釋說--

[近期，卡巴斯基安全軟件安卓版已經上市，
它可以同時保護安卓智能手機和平板電腦設備，

--------------------------------------------------------------------------------------------- *USA9en)-*According to reports, in the past three months,
Kaspersky Lab experts have been ---
- On what is called a Trojan Andrews Obad.a malicious applications -
- Means of communication for investigation.
Investigation revealed that cybercriminals behind the Trojan -
- Use a new means of infection for the -
- The spread of malicious software .
It is also a crime in the history of the mobile phone network ,
The first use of other network crime syndicates -
- Control the spread of botnet Trojans .
Currently , Obad in the CIS ( Commonwealth of Independent States ) countries the most widely spread ,
83 % of infections occurred in Russia.
In addition , Ukraine, Belarus,
Uzbekistan and Kazakhstan, and other countries -
- The mobile device detects that the same horse .
Survey shows
Using multiple versions Obad an interesting mode of transmission ,
Namely the use of Trojan ---- SMS.AndroidOS.Opfake.a spread.
This dual infection means general -
- By sending an SMS to the user to carry out.
SMS text message prompts the user to download the latest received.
If the victim clicks the message link ,
Will move from the download of a file containing Opfake -
- To users of smart phones and tablet PCs .
The user launches the malicious file ,
Malicious programs will be installed.
Once its successful operation ,
Trojan sends infected messages to all contacts in the device .
If you receive these messages a user clicks on a link ,
Trojan will download Obad.a .
This is a very efficient communication systems.
A Russian mobile network provider claims ,
Only within 5 hours , over a network to appear -
- 600 text messages containing such malicious links ,
This suggests that the scale of its spread is very impressive.
In most cases,
The malware has infected devices use spread .
In addition to using botnets to spread outside of the phone ,
This highly sophisticated Trojan also -
- Spread through spam messages .
This is also the main route of transmission Obad.a Trojans .
Typically, mobile phone users will receive a prompt the user to "delinquent ," the message ,
If the user clicks on a link ,
Obad.a will automatically download to your mobile device .
Likewise, only the user run the downloaded file ,
Trojan will be installed on the device .
At the same time ,
Some fake application store will also -
- Spread Backdoor.AndroidOS.Obad.a.
These online application store will be copied Google Play page
And replace one of the legitimate application links to a malicious application link.
When legitimate sites are hacked ,
The user will be redirected to a malicious Web site .
Obad.a attack only for mobile users,
If you use your home computer to visit a malicious Web site ,
Then nothing will happen .
But if you use a mobile operating system -
- Access to smart phones and tablet PCs ,
That will be redirected to the fake malicious website (
Currently only Android users face the risk of infection ) .
" Three -month period , we found a total of 12 different versions -
- The Backdoor.AndroidOS.Obad.a.
These malicious programs all have similar functionality -
- And high interference level code.
Each version of the malicious program will use the Android operating system vulnerabilities ,
Making equipment have administrator privileges malware ,
Makes clear very difficult.
Found that the above situation,
We immediately notified the Google company .
Google has Android 4.3 fixes these vulnerabilities .
But now, only a handful of the latest smartphones and -
- Tablet PC running this version of the Android system ,
Android devices running earlier versions of the system are still at risk.
Different with other Android Trojans ,
Obad.a use a lot of unpublished vulnerabilities infection,
This is very similar to the Windows Malicious Software ,
' " Kaspersky Lab 's top anti-virus expert Roman Unuchek explains -

It can protect both Android smartphones and tablet devices ,

-------------------------------------------------- -------------------------------------------*在最近幾個星期裡的AVAST惡意樣本分析名單中，
Win32/64:Napolar擁有極高的文件和網絡屏蔽率。
另外，我們發現了被冠以Solarbot名稱的新型木馬--
--於2013年5月左右開始做出其相關宣傳廣告，
而這種廣告並沒有發佈在大家經常訪問的黑客論壇，
而是在由主流搜索引擎索引一個叫solarbot.net的網站，
它擁有一個非常專業的外觀設計.*
*Analysis of samples of malicious AVAST list in recent weeks , the
Win32/64: Napolar has a high rate of file and network shield .
In addition, we found that the new name was called Solarbot Trojan -
- In about May 2013 began to make its related advertising,
And this kind of advertising , and we do not publish frequently visited hacker forums
But by the major search engines index a website called solarbot.net ,
It has a very professional design .*
*對於Win32/64:Napolar木馬，
它的進程間通信管道名稱是\\.\pipe\napSolar。
再加上存在的類似“CHROME.DLL”、
“OPERA.DLL”、“trusteer”、
“data_inject”等字符串，
以及後面會提到的功能特徵，
因此我們確定它和Solarbot間存在某種關聯。
讓我們來看看下面的分析。
Dropper
該文件最初以自解壓的壓縮文件形式存在，
--以類似Photo_021-WWW.FACEBOOK.COM.exe --
--這樣的格式命名，
並執行2項工作：
靜默執行dropper以及展示類似下面的辣妹照片
(譯者註：馬賽克是人類文明進步最大的絆腳石)：*
Its inter -process communication pipe name is \ \. \ Pipe \ napSolar.
Coupled with the presence of similar "CHROME.DLL",
"OPERA.DLL", "trusteer",
"Data_inject" such as strings ,
And functional characteristics will be mentioned later ,
Therefore, we determine the existence of an association between it and Solarbot.
Let us look at the following analysis .
Dropper
This document was originally self-extracting compressed file exists ,
- In a similar Photo_021-WWW.FACEBOOK.COM.exe -
- This format is named ,
And perform two tasks:
Silent perform and display similar to the following dropper babes photos
( Translator's Note : Mosaic is the biggest stumbling block to the progress of human civilization ) :
**作者*的聲明中宣稱''Solarbot--
--由Free Pascal的Lazarus IDE所編寫，
但我們想不出任何專業或者--
--商業性質的木馬有此類似特點。
從另一個角度來講，
我們不能確定該代碼是否用Free Pascal編寫的，
因為它PE頭部的許多信息--
--都不同於一般的用Free Pascal編譯的二進製文件。
*核心可執行文件的結構如下：
** Author * statement claiming '' Solarbot -
- Written by the Free Pascal 's Lazarus IDE,
But we can not think of any professional or -
- Commercial nature of this Trojan have similar characteristics .
From another perspective,
We can not determine whether the code is written using Free Pascal ,
Because many of its PE header information -
- Are different from the general use Free Pascal compiler binaries.
Structural core executable file is as follows :
*x86初始的部分，
同時也用於識別系統的體系結構。
而在64位系統中，
還有一個通信模塊被解壓和加載。
LDE64(長度反彙編引擎)是一個32位--
--基於BeaEngine下的官方工具，
它能夠進行32位和64位架構指令解碼。
對於系統函數的修改來說--
--反彙編工作必不可少.
(確保成功的掛鉤一個定制的或模擬的源代碼塊)。
如網站廣告中提到的，
KERNEL32.DLL、NTDLL.DLL、
WININET.DLL、SHLWAPI.DLL、
PASPI.DLL中的所有重要函數都--
--進行了CRC32哈希處理.
(CRC32哈希常數表結構地址在0xFF395A)--
--並將其儲存在''虛擬''表單中。
與IsDebuggerPresent、
OutputDebugString函數相關的--
--反調試技巧也在此有所體現。
安裝到%AppData\lsass.exe後，
在新申請的內存空間0xFE0000處開始運行，
之後bot會自行關閉，
這意味著它不會在進程列表中被發現。
為了了解被這種木馬感染的地區分佈情況，
我們分析了相關檢測部分的運行狀況。
結果表明，每天至少有幾百台計算機被感染，
而這個數字相對於全部Solarbot樣本來講數量略多。
受到感染影響最嚴重的區域為中南美的哥倫比亞、
委內瑞拉、秘魯、墨西哥、
阿根廷以及亞洲的菲利賓、
越南和歐洲的波蘭。

而後通過內部指令0xF進行遠程更新。
接下來我們觀察到，
它下載了一個比特幣挖掘機，
並將其註入到系統臨時目錄的記事本文件中進行了執行.
(對應列表中的“MD5版本更新和系統下載”)。
最後，我們不得不說這個bot所展示的強悍的惡意能力，
再加上$200的合理價格，
近期很有可能大量湧現。
幸運的是，針對此的反病毒軟件將會應運而生，
使這些網絡犯罪種類更加的難以生存。
