I recently learned of this group through the Dark Net Diaries podcast. The host does a pretty good job of covering the NSO group in episode 99 and 100.
It sounded like NSO group just considers loosing zero days like this a cost of doing business.
There seemed to be an implication that they have a war chest of these exploits and expect them to each get burnt after a certain amount of usage.
That's exactly what it is. These companies buy, research and stockpile exploits, and keep a few always at ready for when the currently deployed ones get burned. All exploits have a shelf life, and the more widely one is used, the more likely it is to get caught.
Because let's not forget: NSO and their ilk are not in the business of developing exploits. That's just their raw material. They are in the business of selling weapons-grade espionage and surveillance capabilities.
Massive blow to the integrity of European telecoms.
"The Guardian reported this year that hundreds of thousands of euros of Yana Peel’s legal bills were expensed to the NSO Group by her husband – another move that apparently angered his partners.
Stephen Peel’s lawyers said at that time that the “manner” in which the legal fees were paid had been approved by Kowski and Lueken, and he strongly disputed the suggestion that the payment of the expense claims was a source of disagreement between the partners.
Peel, Lueken and Kowski are all now involved in a legal dispute over the future ownership of the firm they created."
