WhatsApp sends message to get an update after hack

WHATSAPP has urged users to update the messaging app straight away after the discovery of a major vulnerability that could allow attackers to install surveillance software on smartphones.

The Facebook-owned app, which has 1.5billion users, believes a select number of users were targeted by an advanced ‘cyber actor’ exploiting its voice calling feature. It was feared to have been used in attempts to access phones of human rights campaigners, including a UK-based lawyer.

The Financial Times reported the spyware was developed by NSO Group — an Israeli cybersecurity company.

But the firm said: ‘NSO would not, or could not, use its technology in its own right to target any person or organisation.’

WhatsApp said it had shared information with human rights organisations and US law enforcement agencies investigating the breach.
