Zero-click attacks in Cybersecurity

Zero-click attacks in Cybersecurity

What would be your reaction when your cameras, and microphones are activated without your consent?

Scary isn’t it! But, how does this work?

Are your devices vulnerable to cyber-attacks?

Zero click installation has been leading the way in cyber-attacks.

The name Zero-click itself suggests that it targets the users with no click. Intruders break through the mobile and hack the user’s data without any suspicious notifications.

In general, other spyware attacks take place through the user’s direct involvement. It happens when users either click on any malicious link or allow permissions to install applications from any source on the device.

Whereas in the case of Zeroclick attacks, the spyware avails the concealed files and hidden text invade the device with no alerts.

No sooner than the hazardous software stealthily enters the device, it creates an exploit to steal the user’s confidential information and thereby misuse it.

Irrespective of brands ranging from apple to android, this data breach can occur on any device.

In recent times, Pegasus, the spyware has been targeted globally for 50k+ phone no’s.

Pegasus is the powerful spyware developed by the Israeli firm NSO group which has the ability to exploit almost all the versions of android as well as iOS (versions up to 14.6)

Similar to the Zero-click attack, this spyware could be installed into our device remotely. For suppose if the virus is expected to enter through a WhatsApp call, it could make its way to the device even if the user doesn’t receive the call. With the highly crafted secret message, it hacks the device without any kind of target user engagement.

What is the worst that could happen with a zero-click attack?

As it is a matter of risking life and limb, better watch your step. Because from tracking the browsing history to financial records, it steals all the data and could either sell it to third parties or misuse the sensitive information.

How to detect the spyware in our devices?

Detecting Pegasus spyware in our device is definitely a hard nut to crack. There exist no signs to identify it. Because it is built with self-destruction and anti-forensic features and leaves no traces to find even if it is uninstalled.

But according to a few surveys mostly iPhones are the devices that are infected with zero-click attacks. And, Amnesty International, The human rights organization helps in identifying the spyware with an open-source tool “MVT” (Mobile Verification Toolkit). This free tool can scan devices for indicators of compromise (IOC) which acts as evidence that our device is infected with malicious links or texts.

Things to keep in mind:

Here are a few steps to protect your device from different types of cyber security attacks:

  • Don’t get fooled by any links unless it is reliable.
  • Do install applications only from authorized sources.
  • Check for regular updates and upgrade your OS to the latest version.
  • Avoid connecting to public networks such as Wi-Fi services while accessing any sensitive information on our device.
  • Use an end-end encryption mechanism to secure device data and also utilize remote wiping features.


Although we follow the steps mentioned above, it is not that easy to escape from Zero-click attacks since it manages to intrude into our device without our consciousness. But as said, “Prevention is better than cure”, it is always better to be cautious with these types of attacks in cyber security and safeguard ourselves with the necessary action steps.

Also, it would be strictly impossible for any individual to take control of devices unless he/she is aware of cyberattacks and cybersecurity. One needs to be prepared for the types of attacks in network security by registering for cyber security courses online. So, do learn and update with the current trends and cyber technologies by enrolling in our cybersecurity course.
