Meta thought it had stopped NSO Group. It says the spyware firm did not get the message.
The company is filing a federal court contempt order against NSO, the Israeli maker of the Pegasus hacking tool, accusing it of violating a permanent injunction that barred it from ever targeting WhatsApp or its users.
Meta says it has disrupted fresh attacks in the process: new spear-phishing attempts, linked to NSO, that it foiled by dismantling test accounts and groups the firm had created on the platform.
The attempts resembled NSO’s earlier “1-click” campaigns, Meta said in a blog post, the kind of attack where a single tap on a malicious link is enough to compromise a device, with no password required. The links were designed to lure WhatsApp users to external sites. NSO did not respond to a request for comment.
It is the latest turn in a long fight between the two companies.
