JustTalk messaging app sees millions of unencryped messages leak after Twitter lapse
The JusTalk messaging app has been found to store the messages sent by its users in an unencrypted state after they were leaked.
In a report by TechCrunch with help from security researcher Anurag Sen, claims by the company behind JusTalk that claim the app is end-to-end encrypted were proven false. A huge internal data cache included not just millions of messages by users of the app, but also their timestamps and the phone numbers that the messages were sent and received by. The data also extends to call records.
Not only did this data include the above information, but even more granular data like their locations as collected by their phones. TechCrunch also stated that this data was discovered by people other than Sen. The data was reported to JusTalk alongside the report that TechCrunch laid out.
As of this news post, the company has not addressed the issue.
