Additionally, App Store apps are sandboxed, which is supposed to limit apps ability to engage in undesirable behavior.

Together, Apples app review process and sandboxing theoretically make the App Store a more trustworthy software source than most.

Many apps have recently been caught doing unscrupulous things, circumventing protections supposedly provided by the App Store, and invading users privacy.

Privacy 1st reached out to a Mac security researcher, Patrick Wardle, who did further investigation of his own.

However, after the user grants this access, the app proceeds to do some questionable thingsunrelated to the adware scanwithout informing the user.

Another researcher, Thomas Reed, notes in a follow-up article that one could argue that a malware or adware cleaning app might want to check recently browsed sites in an attempt to identify and report back about the source of an infection; however, the user is never informed about or asked to consent to this activity, which takes place surreptitiously in the backgroundeven when no adware is found on the system.

Often it can contain personally identifiable information, or strong clues as to the exact identity of the user.

It may reveal things such as home and work addresses (e.g.

Google Maps searches), medical conditions (e.g.

Trend Micro has issued a statement, saying, Windows products and enterprise products do not have this feature; see below to read more from the statement.

The zip files collected by the apps are uploaded to update.appletuner.trendmicrocom, a subdomain of Trend Micros main site.

Additionally, a May 2018 article on Trend Micros blog advertises and links to Dr.

Cleaner, Dr. Antivirus, Dr.

Unarchiver, and Dr.

Battery in the Mac App Store.

The results confirm that Dr Cleaner, Dr Cleaner Pro, Dr.

Antivirus, Dr. Unarchiver, Dr.

Battery, and Duplicate Finder collected and uploaded a small snapshot of the browser history on a one-time basis, covering the 24 hours prior to installation.

This was a one-time data collection, done for security purposes (to analyze whether a user had recently encountered adware or other threats, and thus to improve the product service).

The data collected was explicitly identified to the customer in the data collection policy and is highlighted to the user during the install.

The browser history data was uploaded to a U.S.-based server hosted by AWS and managedcontrolled by Trend Micro.

We have learned that browser collection functionality was designed in common across a few of our applications and then deployed the same way for both security-oriented as well as the non-security oriented apps such as the ones in discussion.

It still takes a bit more effort for shady developers to circumvent Apples review process, and Apple should certainly learn from this incident and add detection for similar behavior into its app review workflow.
