Jack Dorsey, CEO of Block and co-founder of Twitter, launched Bitchat, an open-source chat application promising secure and private messaging using Bluetooth and end-to-end encryption. Despite claims of security, the app has faced scrutiny as its code has not undergone external security reviews. Security researcher Alex Radocea discovered vulnerabilities allowing identity impersonation, raising concerns over the app’s reliability. Dorsey updated Bitchat’s GitHub page with disclaimers, acknowledging these security flaws and advising against using the app for production until proper evaluations are completed. Critics warn that the current state of Bitchat poses risks, especially for users relying on its supposed security features.
