Facebook WhatsApp is in the midst of a lawsuit against Israeli mobile surveillance outfit NSO Group.

But before complaining about the company methods, Facebook seems to have wanted to use them for its own purposes, according to testimony from NSO founder Shalev Hulio. Last year brought news of an exploit that could be used to install one of NSO spyware packages, Pegasus, on devices using WhatsApp.

The latter sued the former over it, saying that over a hundred human rights activists, journalists and others were targeted using the method. WhatsApp blames — and sues — mobile spyware maker NSO Group over its zero-day calling exploit Last year also saw Facebook finally shut down Onavo, the VPN app it purchased in 2013 and developed into a backdoor method of collecting all manner of data about its users — but not as much as they&d have liked, according to Hulio.

In a document filed with the court yesterday he states that Facebook in 2017 asked NSO Group for help collecting data on iOS devices resistant to the usual tricks: In October 2017, NSO was approached by two Facebook representatives who asked to purchase the right to use certain capabilities of Pegasus, the same NSO software discussed in Plaintiffs& Complaint. The Facebook representatives stated that Facebook was concerned that its method for gathering user data through Onavo Protect was less effective on Apple devices than on Android devices.

The Facebook representatives also stated that Facebook wanted to use purported capabilities of Pegasus to monitor users on Apple devices and were willing to pay for the ability to monitor Onavo Protect users.

Facebook proposed to pay NSO a monthly fee for each Onavo Protect user. NSO declined, as it claims to only provide its software to governments for law enforcement purposes.

But there is a certain irony to Facebook wanting to employ against its users the very software it would later decry being employed against its users.

(WhatsApp maintains some independence from its parent company, but these events come well after the purchase by and organizational integration into Facebook.) A Facebook representative did not dispute that representatives from the company approached NSO Group at the time, but said the testimony was an attempt to &distract from the facts& and contained &inaccurate representations about both their spyware and a discussion with people who work at Facebook.& We can presumably expect a fuller rebuttal in the company own filings soon. Facebook and WhatsApp are, quite correctly, concerned that effective, secret intrusion methods like those developed and sold by NSO Group are dangerous in the wrong hands — as demonstrated by the targeting of activists and journalists, and potentially even Jeff Bezos.

But however reasonable Facebook concerns are, the company status as the world most notorious collector and peddler of private information makes its righteous stance hard to take seriously.
