NSO Group lawsuit (re hacking WhatsApp users)
ソース
Snapshot: In 2019, WhatsApp filed suit in California state court against NSO Group, an Israeli spyware vendor, alleging that the company had hacked the WhatsApp server to plant Pegasus spyware on 1,400 user devices worldwide, targeting journalists, lawyers, religious leaders, and political dissidents. Plaintiffs argue that this is in violation of the U.S. Computer Fraud and Abuse Act (CFAA) and California Comprehensive Data Access and Fraud Act and seek damages as well as an injunction to prevent NSO Group from accessing WhatsApp computer system. The case is ongoing.
Factual Background
On 29 October 2019, WhatsApp, which is owned by Facebook, released a statement alleging spyware, known as Pegasus produced by the Israeli company NSO Group was used to hack the phone systems of 1,400 users between April 2019 and May 2019 in 20 different countries. Of the 1,400 users at least 100 were human rights defenders, journalists, and other members of civil society across the globe.
Legal Argument
WhatsApp is demanding a permanent injunction blocking NSO from attempting to access its computer system and those of its parent company, Facebook. Additionally, they have asked that the court rule that NSO’s alleged hacking of user’s data violated the federal Computer Fraud and Abuse Act as well as the California Comprehensive Computer Data Access and Fraud Act, breached their contracts with WhatsApp and “wrongfully trespassed” on Facebook’s property.
NSO Group disputes these allegations. They argue the sole purpose of NSO is to provide governments and law enforcement agencies with technologies to help them fight terrorism and serious crimes.
Legal Proceedings
On 29 October 2019 WhatsApp filed suit against NSO Group in California court in the US.
On 2 March 2020, NSO Group failed to appear in the California court, resulting in a notice of default entered. NSO responded that WhatsApp had prematurely moved for a default judgment before properly serving NSO with the lawsuit, allegedly violating international laws regarding service of process. Service of process is a legal term referring to the acceptable possible avenues with which plaintiffs can notify defendants a lawsuit has been filed against them and allow them ample opportunity to respond. WhatsApp argued they made several good faith attempts to serve the company.
On 6 March 2020, defendants filed an application with the California state court to set aside the default judgment and raised the issue of incomplete service under the Hague Convention, which details acceptable service of process for international disputes. Additionally, defendants request sanctions be entered against the Plaintiffs for falsely representing to the Court that they had properly served defendants under the Hague Convention. Additionally, defendants argue that plaintiffs had a duty to correct the false statements.
On 13 April 2020, the Court ruled WhatsApp had not intentionally made false statements to the court and given the short time frame, did not usurp their duty to correct the statements to the court.
On 16 July 2020, a US district court judge in California ruled that WhatsApp's lawsuit could proceed. In its ruling, the judge explained not being convinced by NSO's argument that it had no role in the targeting of WhatsApp's users and only followed the directions of its customers. He also ruled that NSO cannot be protected by sovereign immunity as a private company even if it acts as an agent of its foreign sovereign clients.
Based on an appeal filed on 12 April 2021, the US appeals court for the ninth circuit issued its decision on 8 November 2021 rejecting NSO's claim of protection under sovereign immunity laws and allowing the lawsuit to proceed.
On 6 April 2022, NSO Group asked the US Supreme Court to review the decision of the appeals court for the ninth circuit. It asks to be recognised as a foreign government agent and therefore be entitled to sovereign immunity.
In June 2022, the US Supreme Court asked the Justice Department to provide its view on whether NSO Group has sovereign immunity to decide if the lawsuit can proceed.
On 9 January 2023, the US Supreme Court found that NSO Group lacked sovereign immunity and allowed the lawsuit to proceed in the US District Court for the Northern District of California.
In March 2023, six Moroccan activists who claim to be the "victims of illegal intrusion into their phones by Pegasus software" announced that they would join Whatsapp's lawsuit against NSO in California.
On 23 February 2024, a judge ordered NSO Group to hand over its code, specifically instructing the company to provide relevant spyware code for the period spanning from one year before the alleged targeting of WhatsApp users in 2019 until one year after the supposed attacks concluded in May 2020.
In November 2024, it was disclosed that sworn depositions from NSO employees revealed that the company —not its government clients—directly “installs and extracts” data from targeted phones using its Pegasus spyware. This disclosure contradicts NSO's claim that its clients operate the system independently. Testimony detailed how Pegasus automatically accessed WhatsApp servers to compromise devices and identified instances of severe misuse. NSO maintains its stance that it has no access to intelligence and operates under strict regulations as the case continues.
Lawsuit filed by NSO Group Employees against Facebook in Israel
On 26 November 2019, employees from NSO Group filed a separate lawsuit in Israel against Facebook Inc (which owns WhatsApp), alleging the social media giant had blocked their private accounts when it sued NSO in October 2019. They petitioned the Tel Aviv district court to order Facebook to unblock the accounts. Facebook responded that they had disabled relevant accounts after the cyber-attack and that the restrictions continue to be necessary for security reasons.
