Hackers have developed a software which allows them to listen into WhatsApp users – without the victims knowing they are being spied on.

The app found a vulnerability which allowed attackers to remotely install malicious code on both iPhone and Android deceives by calling the target phone.

Hackers are able to install the software on your phone – even if the target phone is not answered.

After the software is installed, hackers can control your phone’s microphone and camera.

The company, owned by Facebook, said the malicious software resembled a spyware developed by intelligence agencies.

A new software update was released by the company, which has more than 1.5 billion users across 180 countries.

There are concerns the software was used to try and gain access to phones of human rights campaigners, including a UK-based lawyer.

“We believe a select number of users were targeted through this vulnerability by an advanced cyber actor,” WhatsApp told the FT.

“This attack has all the hallmarks of a private company known to work with governments to deliver spyware that reportedly takes over the functions of mobile phone operating systems.

WhatsApp has just pushed out updates to close a vulnerability. We believe an attacker tried (and was blocked by WhatsApp) to exploit it as recently as yesterday to target a human rights lawyer. Now is a great time to update your WhatsApp software https://t.co/pJvjFMy2aw https://t.co/e8VQUraZWQ
