What is Screencapture.app
Screencapture.app belongs to the category of Trojan infections. A Trojan virus or a Trojan horse is a type of malware which infiltrates your Mac and starts performing malicious operations.
Due to the fact that Screencapture.app uses rather similar tactics to the Trojan viruses, it carries an identical name. In this case, users are manipulated to believe that they are downloading a software update or opening a legitimate email attachment, however, they are actually installing malware on their computers.
For example, when you install a Flash Player update or just open an email attachment on your Mac, you can install Screencapture.app alongside not having a clue about it.
Once Screencapture.app enters the system, it tries to gain control of your computer, keeps a track of all your browsing activities, records your banking details and passwords, and performs other malicious operations.
In the meantime, Screencapture.app tries to remain undetected by your antivirus software to stay onto the system as long as possible. For that reason, you should remove it from your Mac as soon as you notice its presence there.
How is Screencapture.app distributed
Despite the fact that Trojans are not the most popular macOS infections, sometimes they can infiltrate Mac computers via malicious email attachments and fake downloads.
There are different types of Trojans, however, all of them enter the system in the same way. So does the Screencapture.app which infiltrates your Mac via legitimate email attachments, such as invoices, CV, or other supposedly legitimate documents containing malware.
Another way for distributing Screencapture.app is via fake downloads. For example, when people install a software update, they hardly read every step of the installation process and the Trojan enters their computers without their knowledge or permission. Thus, when updating a program, or installing new software, users should always read “Terms and Conditions” carefully and be aware of everything they launch onto their Macs.
In order to keep your Mac safe, you should never trust any websites that demand you to update Flash Player or any other program on your computer. If you do want to update them, the only safe source is their official websites.
Also, do not download software from any torrent website as they often contain malware. And the most important thing we already mentioned above – when you install new software, always read the “Terms and Conditions” carefully and keep your antivirus program on at all times. Otherwise, your online security might be seriously threatened.
