Here is a list of some well-known spywares:
Pegasus spyware is making headlines these days due to its threat potential. Pegasus is a piece of software developed by the Israeli cyber arms firm NSO Group that can enter the device directly. The spy can use this software to take screenshots, listen to the calls, read messages, and access browser history and contacts. Since this malware is constantly updated, cracking this spyware is nearly impossible.
The Exodus spyware software is created by the Italian company eSurv. This software is not overly complicated. Exodus spyware can infiltrate your device simply by installing an app and then accessing your data including contact list, photos, and apps.
CoolWebSearch poses a significant risk to the information on your device. It has the ability to take over your browser, home page, and settings causing your system, browser, and Internet connection to slow down.
Gator spyware gains access to your personal information, such as your credit card number, passwords, address, and location, and saves it on a server. Also, if this is installed on the system, it will continue to display advertisements.
