Reed claimed that the app itself has a long track record of unscrupulous behaviour: it was previously called "Adware Medic" - a title which Reed said was a "rip off" of his app of the same name.
Apple responded by kicking the offending apps out of the App Store, and Trend Micro started an investigation into the privacy concerns raised about Dr Cleaner, Dr Cleaner Pro, Dr Antivirus, Dr Unarchiver, Dr Battery and Duplicate Finder.
Adware Doctor and Komros Adware Cleaner (same developer behind them), Open Any Files and Adblock Master relied on the same technique to lift the information from users.
Apps on Apple's Mac App Store are reportedly collecting and uploading your browser history and other data without your knowledge.
However, this incident suggests that these stores can not be fully trusted as some of the most popular apps (Dr. Unarchiver is #12 most popular free app in the US Mac App Store, Adware Doctor is #1 paid utility app) there are putting user data at risk.
Trend Micro blamed the behavior on the use of common code libraries and has now removed the browser data collection feature and deleted logs store on the AWS servers.
Dr Cleaner, Dr Antivirus, and App Uninstall - utilities owned by the Japan-headquartered security house and distributed on the Mac App Store - are no longer available for download.
The apps have been reported to Apple since at mid-August and are now removed from the Mac App Store.
We reached out to Trend Micro for a statement on the matter but received no reply at the time of publishing. Both apps are collecting and uploading user data, including browsing history, to their servers.
The company notes that it disclosed this data collection in its end-user license agreements and that browser history data was uploaded to a USA server hosted by Amazon Web Services and managed by Trend Micro.
"From a security and privacy point of view, one of the main benefits of installing applications from the official Mac App Store is that such applications are sandboxed", Wardle blogged. A representative of the company told BleepingComputer that the company statement would be updated continuously.
