But the reliability of the app’s code is integral to this privacy promise, which is why Proton is making its mobile apps open source - lives could literally depend on it. Like WhatsApp, ProtonMail’s core proposition is full encryption, which means nobody can intercept and read your messages in transit. More broadly, countless reports have emerged of late around a flaw in WhatsApp that was used to spy on journalists, activists, and senior government officials. The reason why Proton prioritized iOS over Android was due to the fact that it had “received threat intelligence about a suspected Chinese malware targeting activists using iOS devices,” a spokesperson told VentureBeat. While there have been historical instances of activists and human rights defenders being targeted through iOS vulnerabilities by state-hackers, last month Amnesty announced that a Moroccan human rights lawyer was targeted with spyware from Israeli cyber intelligence firm NSO, which helps nations deploy mobile surveillance technology.
