NSO Group could be exposed to liability from other technology groups for exploiting their platforms’ vulnerabilities

Meta won its case in December after a ruling that the spyware company used Pegasus to target "over a thousand" WhatsApp users.

The Israeli firm behind the Pegasus spyware has been ordered to pay WhatsApp $167m (£125m) for hacking 1,400 people in 2019. Pegasus is malicious software which can be installed remotely on mobile phones to access, among other things, people's microphones and cameras.
