WhatsApp is taking legal action against an Israeli firm after the company detected a new wave of targeted attacks on its users. Meta Platforms Inc. filed documents asking a federal court to hold NSO Group in contempt for violating a previous court order that banned the firm from targeting WhatsApp accounts.
Meta Platforms files federal contempt motion against Israeli cyber-intelligence firm
The messaging platform accused NSO Group of launching spear phishing campaigns designed to compromise user devices. Security teams at WhatsApp identified and blocked these attempts before they could succeed. The company shared details about the malicious domains used during the attacks, including ikhwancast[.]com, ghazacast[.]com, and fr24cast[.]com.
NSO Group previously operated under a 2025 US court injunction that explicitly prohibited targeting WhatsApp users. The new spear phishing attempts represent a direct violation of that legal restriction. WhatsApp security teams successfully intercepted the malicious links and prevented unauthorized access to user accounts.
The platform now seeks judicial enforcement against NSO Group for ignoring the established court order. This contempt filing follows WhatsApp's successful defense against the latest attack wave. The company continues to monitor threats and share technical details about active campaigns with its user base.
