Our work on telecom network exploitation has helped choke off access to phone networks by commercial surveillance actors. Findings from our Flight of the Predator investigation contributed to the sanctioning of bad actors by the US Office of Foreign Asset Control. Our Ghost in the Network investigation led to a recommendation by the GSMA that its members cut off Andreas Fink’s access. Our exposure of Italian geolocation firm Tykelab led to a sudden decrease in traffic observed from it.
