The product manual for NSO's Pegasus spyware [pdf]
s3.documentcloud.orgAmazed by the shear infrastructure size to host the solution. Requires two 42U racks!
What's missing is the date of the manual, assuming it's maybe 8-12 years back? Would be interesting to see an up-to-date product manual and how these threat-enablers evolve over time.
The android versions mentioned point to 2012/2013
Same with iOS v6.1.4 is 2013-05
It has a nice UI. Perhaps QT?
