Once on your Mac, a backdoor could:

  • Activate your camera or microphone;
  • Log your keystrokes;
  • Track you location via FindMyMac;
  • Read your IP and MAC addresses;
  • Copy files from your Mac;
  • Delete files from your Mac;
  • Steal AppleID passwords and IDs;
  • Steal saved passwords on your browser;
  • Download other viruses on your Mac without your knowledge;
  • Update itself.

Let’s have a look at a recently detected Mac backdoor, [wplinkpreview url=”https://sensorstechforum.com/longage-trojan-mac-remove/”] Longage.A Backdoor.

Based on data collected by malware researchers, it is known that the backdoor could help hackers to deliver additional malware. Furthermore, as long as the connection remains uninterrupted, hackers could perform some or all of the following actions:

  • Gather information about your computer;
  • Send a list of currently-running processes;
  • Kill processes;
  • Run or delete files;
  • Receive files from, or send files to, a remote server;
  • Uninstall Longage.A Backdoor;
  • Send an Apple event to initiate your computer to sleep, restart, shut down and log out;
  • Open a bash shell command prompt.

The worst part is that a backdoor may stay silent and undetected on your system for a long period of time, making it an infection difficult to spot and remove.

A Mac backdoor Trojan may also open the door to other infections on your Mac, or may be dropped together with other malware, such as the following:

Banking Trojans, which are designed to steal banking and financial information. These Trojans could inject a virtual layer over legitimate banking websites with the purpose to collect information entered by the user.
Downloader Trojans, which are designed to install more malware on affected systems.

DDoS Trojans, which apply a botnet on infected systems to be used to execute DDoS attacks.

Spyware, which is designed to stealthily infiltrate Macs to track and record keystrokes, websites visited, and can even take screenshots of the users’ activities. Collected data is typically sent to a command and control server.

PUPs and adware, which interfere with the victim’s online activities by displaying pop-up ads and fake error messages, and redirecting to suspicious sites.

Shortly said, a Mac backdoor Trojan detection may be an indication of other infections.
