Commenting on Whatsapp's announcement that it will encrypt all users messages, Dina Shiloh, a Privacy lawyer at Mishcon de Reya, said:
"This is essentially a positive development, designed to protect the public from unsophisticated illegal hacking of a widely used platform. It responds to growing concern about data protection, and illustrates that people are now much more aware of the risks of using free services such as Whatsapp – something that simply wasn't the case even five years ago.
"As has been recently demonstrated however, ultimately nothing is impenetrable. It is also worth noting that, whilst the content of messages may now be protected, other data still appears to be easily accessible – for example, the location of phones can still be tracked, as can details of who messages are sent to and at what time."
