Pegasus spyware developed by the NSO Group is in the spotlight after international media organizations collaborated on a massive report revealing governments in the company's clientele using the malware to surveil different persons of interest. Find out how you can tell if your smartphone is infected with the spyware and how you can use Amnesty's toolkit.

What is Pegasus Spyware?

The Pegasus spyware works as malware that infiltrates smartphones via apps like iMessage and WhatsApp. Victims can also introduce the spyware into their devices by inadvertently clicking a link containing the vulnerability, Time explained. The Israeli NSO Group insists it is only intended for use against criminals and terrorists, but the investigation was done by The Guardian and 16 other media organizations revealed widespread and continuing abuse of the spyware.

Spyware like Pegasus takes advantage of known and unknown flaws in a computer's operating system until the companies making the devices roll out fixes.

The NSO Group has also demonstrated the ability to install malware on devices with zero need for interaction from the victim. Receiving a call from someone attempting to infect a device was enough to successfully infiltrate the operating system's defenses without raising any alarms. The spyware is difficult to detect as it exists in the smartphone's memory, similar to other malware like ransomware.

Once installed, Pegasus can harvest practically any data from the device and transmit it back to the attacker, The Guardian explained. The spyware user can secure a log of the phone owner's past movements and track their location in real-time with pinpoint accuracy, including the speed at which their car was traveling.

In the data leak provided by Paris-based journalism nonprofit Forbidden Stories and Amnesty International, around 50,000 phone numbers were potential surveillance targets, TechCrunch said.

The list contained phone numbers of more than 180 journalists, including reporters, editors, and executives at the Financial Times, CNN, the New York Times, France 24, The Economist, Associated Press, and Reuters. Phone numbers of lawyers, activists, journalists, political opponents, government critics, as well as relatives of these individuals were also found in the list.

At least 10 governments are believed to be NSO's clients who were entering numbers into a system: Azerbaijan, Bahrain, Kazakhstan, Mexico, Morocco, Rwanda, Saudi Arabia, Hungary, India, and the United Arab Emirates (UAE), The Guardian revealed. The phone numbers were from 45 countries across four continents.

The NSO Group still maintains it "does not operate the systems that it sells to vetted government customers, and does not have access to the data of its customers' targets."

4 Ways to Tell if Your Android is Infected with Pegasus or any other Malware

Look out for these warning signs of an infiltrated smartphone. Using the recently released toolkit should also be helpful in scanning your device for any malicious software.

4. Check for signs of battery drainage

Spyware can drain an excessive amount of battery from your device. See if your battery is depleting very quickly or that you find yourself needing to charge your phone often.

3. Check for encrypted text messages

Receiving strange SMS messages that look like code could be a worrisome sign that the device is hit with spyware. Beware of other texting scams like smishing that steal sensitive information from devices as well.

2. Check for high data usage

When your phone is hacked, the hacker is trying to extract data from your phone which means it needs a connection to transfer that data. Go to Settings then tap Connections. Select Data usage and then review your current amount of available data.

1. Use the Mobile Verification Toolkit

The MVT scans the device backup for text messages with links to domains known to be used by NSO as well as any potentially malicious applications installed on the device, Tech Crunch explained.
