Whatsapp Breach: How it happened, and how to update your Whatsapp.
The company discovered a vulnerability that allowed attackers to install malicious code on iPhones and Android phones by ringing up a target device.
The code could be transmitted even if users did not answer their phones and a log of the call often disappeared, the Financial Times reported.
Whatsapp said the attack bore a resemblance to spyware developed for intelligence agencies.
There are concerns that the software was used in attempts to access the 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.
The security level of mobile devices should be a constant concern, not just when headlines hit. Just last week we published a whitepaper on the key things every company should be aware of when it comes to mobile security. One of our main pieces of advice is to be aware of the perception gap people have when working on their phones, they are not safer than a desktop machine, and events like this really highlight that.
