Researchers at McAfee Labs found a malicious app named BMI CalculationsVsn on the Amazon Appstore, disguised as a body mass index calculator. The app activates screen recording when users click the “Calculate” button, potentially capturing sensitive information. Although it was designed to record video, the developer had not implemented the capability to upload recordings. The app could still scan for installed applications and collect text messages. It was uploaded to the Amazon Appstore in early October and was removed after McAfee alerted Amazon. Users who installed it need to delete it manually.
