Gmera Mac Trojan Virus Capabilities

When the Gmera Mac Trojan is started it will run a initial infection script which will trigger the sequence that will oversee the installation of the malware.

One of the first actions which are run involve the collection of data from the Mac computers, in most cases the information is separated into two categories:

  • Personal Users Information — This can expose the identity of the users by looking for information related to their name, address, phone number and other related data. If additional functionality is added the main engine can also scan the browsers memory and hijack their browsing history, including bookmarks and saved passwords.
  • Machine Metrics — The main Trojan engine can create a report of the installed hardware components and the operating system variables. This can be used to generate an unique identification code that can be applied to any system.

Following this the next component which will be run will install the threat as a persistent infection. This means that the virus code will be run every time the computer is started. This is done by editing out configuration files and system settings.

When the Trojan initiates its remote connection feature it will run a local agent which will establish a strong and secure connection to a hacker-controlled server. This will be done to different TCP ports evading the most commonly used in order to bypass possible firewall checks.

In comparison to other common Mac Trojans Gmera includes some unique features:

  • The collection of a wide range of data including external IP addresses, the Mac model specifics and other data. While other common malware stops when all hardware components have been listed, this also extracts the disk usage and connected monitors.
  • It can list the available Wi-Fi networks and other connections
  • It can detect if there any installed security applications and services installed and disable them

As always Trojan threats like this one are designed to hijack user data and take over control of the machines.
