Meta says it will take legal action against NSO, an Israeli spyware company, citing harm linked to its technology. Multiple reports state that Meta’s services—particularly WhatsApp—helped thwart phishing attempts that were associated with NSO. Meta says it prevented or disrupted campaigns designed to trick users into clicking links or installing malicious software. In addition, reporting notes that NSO has faced scrutiny and restrictions from the US. One outlet says the company is blacklisted by the US over security concerns. The overall picture across sources is that Meta is pursuing legal remedies while also describing operational steps to protect users from threats it links to NSO-linked activity. While details of the legal claims are not specified in the provided excerpts, the reports converge on the same core elements: Meta’s planned legal action, the disruption of phishing attempts tied to NSO, and the company’s existing status and concerns raised by US authorities. The accounts also indicate that Meta continues to monitor and respond to threats affecting its platforms.
