According to the available information this particular Trojan has an emphasis on finance related applications such as trading software and applications which means that it may be geared against professionals working in the sector. The hackers have created landing website landing pages that advertise these viruses as legitimate installers. The Trojanized apps themselves are made by taking the original setup files and adding in the necessary virus code. This will only a very bit the original file size and the users won’t notice the difference.
Such fake download portals are also created specifically in order to mimic the legitimate software vendor sites, mirrors or other places where such software can be downloaded from. The most important elements included in them are the following:
- Similar Sounding Domain Name — The criminals will likely use a similar sounding domain name which may confuse visitors into thinking that they have accessed the real site. This is often done by creating copycat pages which are hosted on the so-called “mistyped names”.

The Trojanized virus-infected files are delivered in a ZIP archive file which includes the malware application.
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.
