Official Description

SMAs are a class of applications running on mobile devices which are increasingly targeted by malicious attackers, such as APT groups. Not only do they transmit private communications that the user believes to be secure, but SMAs can reduce the security of the mobile device itself: unlike most mobile applications, an attacker only needs a phone number or username to communicate directly with the SMA. The SMAs in wide use today all share similar cryptographic protocols, software architectures and...
