Pegasus is spyware developed by the Israeli cyberarms firm NSO Group specifically designed for governments. It says the software is intended for use against criminals and terrorists and is made available only to military, law enforcement and intelligence agencies from countries with good human rights records.

It installs itself onto the device running most versions of iOS and Android and starts beaming out your data or what you’re doing your activity,your internet behaviour to the attacker

It operates as a zero-click vulnerability, requiring the targeted user to take no action. A single missed call or message on WhatsApp might lead to the spying on you or your device. They can remotely access your mike and even your camera to spy on your photographs, videos, emails, messages, incoming and outgoing calls, and their records. Technically, the strength of this malware is so great that a regular user will not even notice it.

On your device, there are a few things that you should notice on?

  • Unusual battery drain: Even when you are not using your smartphone, the battery level begins to deplete rapidly. May be some kind of unusual application running in background.
  • Unusual photos and videos on your gallery: Because your camera might have been remotely manipulated by an attacker, you won’t be able to remember those images and videos when you’ve taken them or the picture may not have been taken by you.
  • Phone acts slow: Your phone might be old, which is one reason for its slowness, but odd behavior could indicate that your phone is processing a lot of data in the background.
  • Too much data usage: The phone begins to display an indication that you have used a lot of data. It signifies that your information is being delivered and received somewhere.
  • Unusual call logs and messages: You have no idea when you made this call or received these messages, or what sort of message you are viewing, and you can’t figure out what this message is trying to convey.
  • Apps crashes and acts weired:When you open an app, you may see random popups stating that the program has crashed and is behaving strangely.
  • Unrecognized apps in phone :Your phone may have been hacked if you notice random applications or undefineable apps that you didn’t know about when you installed them or what they do is already on your device.
  • Flashlight turns on automatically:The flashlight on your phone occasionally turns on automatically without being turned on.
  • Phone overheating: If you notice your phone warming without performing any hard tasks or utilizing it, there’s a chance it’s processing a lot of data inside by an attacker.
