Vulnerability in open iPhone app recorded phone calls

Sensitivity was found in an iOS call recording app enabling recorded phone calls by knowing a user’s phone number.

Explained today by Anand Prakash of PingSafe AI, the vulnerability was discovered in an app called “Automatic Call Recorder” that has been downloaded over a million times from the Apple App Store. As the name implies, the app automatically records incoming and outgoing phone calls.

The vulnerability associated with insecure communication went in and out of the app. Using a proxy tool like Burp Suite, Prakash was able to view and modify network traffic, allowing it to assign another user number in the registration request. The app programming interface would then match the URL of Amazon Web Services Inc.’s S3 storage bucket. where storage was.

The company behind Automatic Call Recorder was notified of the vulnerability and a new version of the app went live on the App Store March 6. It is recommended that any users who do not automatically update their apps be updated. apply as soon as possible.

“Security issues like this are terrible in nature,” Prakash said. “As well as influencing customer privacy, these will also distort the company’s image and provide additional benefits to its competitors.”

Anurag Kahol, chief technology officer at cloud access security broker Bitglass Inc., told SiliconANGLE that anyone could have accessed thousands of call logs during the time of appearance just by knowing a user’s phone number .

“This not only violated data privacy but also put the affected users at physical and cyber risk if their recorded conversations contained personal, sensitive details,” he said. . “App makers who do not invest in cybersecurity themselves need to recognize that the potential fines for non-compliance with data privacy laws are very costly – not to mention the cost of loss of customer trust. ”
