Surveillanceware campaigns

The trend of commercial surveillanceware families has been observed recently targets Libya users via SpyMax .SpyMax and SpyNote were developed by the same creators.

These are Remote Access Trojans (RATs) for Android devices that may pack a lot of features that enable their authors with the ability to carry out a broad range of unsafe operations on the infected device.

Below apps were trojanized apps used in the campaign and not available on the official Google Play Store, suggesting they were likely distributed through actor-operated watering holes or third-party app stores.

AndoServer samples receive commands, and are capable of:

  • Taking a screenshot
  • Getting battery levels and if the device is plugged in
  • Reporting location (latitude and longitude)
  • Getting a list of installed applications
  • Launching an application specified by the malicious actor
  • Checking the number of cameras on a device
  • Creating a specific pop-up message (toast)
  • Recording audio
  • Creating a file on external storage
  • Exfiltrating call logs
  • Listing files contained in a specified directory
  • Calling a phone number
  • Exfiltrating SMS messages
  • Sending SMS to a phone number
  • Exfiltrating the contact list
  • Playing a ringtone and then sleeping
  • Choosing a specific camera to access

Syrian authorities are known to heavily censor their country’s internet, with Syria ranking 174th on Reporters Without Borders 2019 World Press Freedom Index.

Given Syria’s history of censorship and past mobile and desktop surveillance campaigns, it should come as no surprise that another campaign is active.
