This section details how the malware utilizes each of these channels to communicate with the remote C2 servers. SpyDealer registers a broadcast receiver with a higher priority than the default messaging app to listen for the commands via incoming SMS messages.
The commands received through SMS are first decoded for further parsing and processing. Each SMS command contains a command index and arguments split by a newline. The command index ranges from 1 to 5 and each command is detailed in Table 3. To get the geographical location based on the GSM cell information, SpyDealer takes advantage of the interface of Baidu map service Figure 9.
It first collects the GSM cell identity, area code and network operator and then posts the encoded data to the Baidu map service to retrieve the geographical location.

However, if it receives a command index of 3, 4, or 5, SpyDealer will acknowledge that a command was received by sending back a specially formatted SMS response. All incoming SMS messages that contain commands will be aborted, which means the user will not be aware of these messages. However, other types of SMS messages will also be blocked if the malware is set to do so or the incoming number is in the blocking list. SpyDealer creates a TCP server on the compromised device listening at port and waits for incoming commands.
The command format and description are listed below in Table 4. The command data received by the client is encrypted by the server using Tiny Encryption Algorithm TEA Once the client receives a command, the malware decrypts the data Figure Each command starts with the command followed by a newline character and the base64 encoded arguments. Table 5 details a full list of commands available through this channel. One interesting command is named SendMsg. Previously, Android malware could fake an incoming SMS message by exploit the Smishing vulnerability , which was patched in Android 4.
To achieve this effect in newer Android versions, SpyDealer first inserts an SMS message into the inbox and then posts a notification indicating an SMS message has arrived. To our knowledge, this is the first malware family that fakes an incoming SMS message in this way. The default one is UDP. The duration argument specifies the duration of the video.
All the sub-commands are detailed in Table 6.

The data sent back to the remote server is encrypted using TEA algorithm. Because UDP is a sessionless protocol by design, there is no guarantee that all transmitted packets will be received by the destination without any loss. SpyDealer divides the original data into multiple groups and each group has no more than bytes data. These groups are sent one by one and every transition is repeated three times. In order to restore the data at the server side, an additional identification code is added at the beginning of each grouped data.
Hence, the format of the final group data is shown below:. Additionally, with root privilege, SpyDealer also tries to gather data from more than 40 common apps falling in different categories including social, communication, browser, mobile mail client, etc. The targeted apps are listed in Table 7. The data to be collected is not only limited to database files, but also includes some configuration and other specific files.
Table 8 listed some target apps and various directories, databases and files which the malware tries to access. An increasing number of apps encrypt data before storing it into databases, especially for some popular communication and social apps. App developers do this to protect user data from malicious attacks like this one.

To avoid this obstacle, starting in version 1. Figure 12 depicts the accessibility service configuration in which the package names of targeted apps are declared. The command used to enable the accessibility service is depicted in Figure Figure 13 Enable accessibility service silently via executing command with root privilege. Usually, a user will click the notification to view the message, which brings the detail view to the front.
SpyDealer is capable of surveilling a compromised victim through multiple means including recording phone call and surrounding audio, recording video, taking photos, capturing screenshots, and monitoring geographical locations. It takes these actions based on commands it receives from the command and control channels described above. SpyDealer registers a PhoneStateListener to monitor the phone call status. Once there is an active phone call, the audio recording procedure is triggered. The recorded audio data is finally compressed in zip format and stored to.
In addition to recording phone calls, SpyDealer is also capable of recording surrounding, ambient audio. It can be configured to record audio at a specific time range. The recorded audio file is stored to the following path in zip format. SpyDealer checks to see if the camera is available to record a video every three seconds. In the Android system, a preview surface is required to take a video, which means the user is aware of the video recording event. To avoid this, SpyDealer intentionally sets a very tiny preview surface which, in this case, is 3. Each video is recorded for 10 seconds and is finally stored to.
Using the front or rear camera depends on the configuration which the attacker can set remotely. The taken photo is stored to. Whenever the screen is turned off, it tries to get the geographical location via GPS. This location listener is notified with the updated location every 10 seconds or whenever meters of movement occurs between location updates. If a network connection is available, the location data will be sent to the remote server in the format.
However, the location data is saved locally if there is no network connection and will be uploaded later when the connection is restored. Besides many powerful capabilities described above, SpyDealer is also capable of automatically answering an incoming phone call and dynamically loading plugins downloaded from the remote server.
If the incoming phone call is from a specific number, which can be remotely configured, this malware will simulate an earphone plugged event to automatically answer the phone call, which is detailed in Figure With this functionality, SpyDealer can let the victim miss phone calls without their awareness. It employs a wide array of mechanisms to steal private information.
At the same time, it accesses and exfiltrates sensitive data from more than 40 different popular apps with root privilege. With accessibility service, this malware is also capable of extracting plain text messages from target apps at real time. To remotely control the victim device, the malware implements three different C2 channels and support more than 50 commands.
WildFire is able to automatically classify SpyDealer samples as malicious and AutoFocus users can track this malware using the SpyDealer tag.
