Over the past year, privacy of communication apps like whatsapp was brought into focus after the company Pegasus was able to hack phones over whatsapp using what was called a “zero-day exploit”.
Signal, contrary to whatsapp is an app that provides enhanced security, privacy features, and comes highly recommended by security experts. While i understand that no app is secure from a zero-day exploit, can hacks of one’s phone though say whatapp, or some some app be used to obtain details of conversation that happened over Signal. Does signal have any measures that provide (partial) security against such hacks ?
Does it make sense(even to some degree) to use signal on devices which may use other apps which have a higher susceptibility to being hacked.
