According to Anand Prakash, a security researcher and founder of Pingsafe AI, a vulnerability was discovered with the Call Recorder app that allows anyone to listen to a call that has been recorded and saved to the cloud using the service. His research found that all anyone needed to access the sensitive recordings was their target’s phone number and the use of a common tool used to test the security of programming known as a “proxy tool.” TechCrunch verified the findings by using a spare phone to replicate the results.ae0fcc31ae342fd3a1346ebb1f342fcb Fortunately, Prakash immediately reached out directly to the app’s developers to alert them to the danger, writing in a statement: “The vulnerability allowed any malicious actor to listen to any user’s call recording from the cloud storage bucket of the application and an unauthenticated API endpoint which leaked the cloud storage URL of the victim’s data.” This means that the app’s security hole allows potential hackers to mask their own phone number as their target’s, granting them access to whatever recordings have been made by their account. Unfortunately, the security breach could have pretty far-reaching consequences, as the app claims to have been downloaded by millions of users. It currently promotes itself as one of the top 20 most popular business apps in more than 20 countries, offering the ability to record incoming and outgoing calls for record-keeping purposes and transcription services of such calls in over 50 languages, PhoneArena reports.

The app’s developers worked quickly to patch the security flaw after Prakash reached out to them with the discovery, relaunching a secure version of the app on March 6, TechCrunch first reported. It is recommended that anyone who currently has the app on their phone delete it and redownload the latest version as soon as possible to make sure that data isn’t being left exposed.
