- Event Type
- Reports of commercial surveillance technology use against civil society: Citizen Lab assessed with high confidence that Cellebrite forensic extraction tools were used on Boniface Mwangi’s phone in Kenyan police custody, and Amnesty confirmed Predator spyware infected Teixeira Cândido’s iPhone.
- Impact
- Mwangi’s phone was returned unlocked; Citizen Lab said Cellebrite use could have enabled extraction of messages, files, passwords, financial information, and other sensitive data, but did not confirm what was extracted.
