Some of this data is actually being sent to Chinese servers, which may not be subject to the same stringent requirements around storage and protection of personally identifiable information like organizations based in the US or EU. Several security researchers have independently found different apps that are collecting sensitive user data and uploading it to servers controlled by the developer. It was eventually removed, but was replaced soon after by an identical app named Adware Doctor.We’ve continued to fight against this app, as well as others made by the same developer, and it has been taken down several times now, but in a continued failure of Apple’s review process, is always replaced by a new version before long. We immediately began detecting this, and contacted Apple about removing the app. At that time, we discovered an app on the App Store named Adware Medic—a direct rip-off of my own highly-successful app of the same name, which became Malwarebytes for Mac. The developers found a loophole that allowed them to access that data despite Apple’s restrictions.The developer of this app is one that we at Malwarebytes have had our eye on since 2015. In the case of the list of running processes, the app had to work around blockages that Apple has in place to prevent such apps from accessing that data. ![]() Antivirus on the App Store. It is still present on the App Store.As we were investigating, we found it very odd that Open Any Files was promoting Dr. Complete Firefox browsing and search historyWe reported this app to Apple in December 2017. Adobe cs3 download for macHowever, even within the user folder, most of antivirus apps in the App Store don’t have a good detection rate, and this was no exception.Worse, however, was that we observed the same pattern of data exfiltration as seen in Open Any Files! We saw the same data being collected and also uploaded in a file named file.zip to the same URL used by Open Any Files.This file, though, contained an interesting bonus. AntivirusOn investigating, we learned that this app, like most Mac App Store apps, is limited in what it can detect to begin with, due to restrictions imposed by the App Store. Antivirus, as well as a number of other apps.(Recently, Open Any Files stopped exfiltrating this data, but we have retained the evidence from our observations.) Dr. We observed the same data being collected by Dr. CleanerUnfortunately, other apps by the same developer are also collecting this data. In addition, there was nothing in the app to inform the user about this data collection, and there was no way to opt out of this data collection. But it is very hard to argue to exfiltrate the entire browsing history of all installed browsers regardless of whether the user has encountered malware or not. Antivirus.)It could be argued that it is useful for antivirus software to collect certain limited browsing history leading up to a malware/webpage detection and blocking. (See a short excerpt from the file below, showing only the information listed for Dr. In some cases, we’ve seen offending apps removed quickly, although sometimes those same apps have come back quickly (as was the case with Adware Doctor). This is not new information, but these issues reveal a depth to the problem that most people are unaware of.We’ve reported software like this to Apple for years, via a variety of channels, and there is rarely any immediate effect. I’ve been saying this for several years now, as we’ve been detecting junk software in the App Store for almost as long as I’ve been at Malwarebytes. What does all this mean?It’s blindingly obvious at this point that the Mac App Store is not the safe haven of reputable software that Apple wants it to be. WHOIS records identified an individual living in China, and having a foxmail.com email address, as being the registered owner of the domain. There is really no good reason for a “cleaning” app to be collecting this kind of user data, even if the users were informed, which was not the case.Interestingly, we found that the drcleanercom website was being used to promote these apps. Worse, even if you don’t give it access, it may find a loophole and get access to sensitive data anyway.If you download one of these apps and are now regretting it, you can report the app to Apple:Thanks go to folks who have spent their spare time finding and poking at these applications over the last year: PeterNopSled (from the Malwarebytes forums), and Patrick Wardle. A free app from the App Store may seem perfectly innocent and harmless, but if you have to give that app access to any of your data as part of its expected functionality, you can’t know how it will use that data. Be cautious of what you download. Case in point…all of the above.I strongly encourage you to treat the App Store just like you would any other download location: as potentially dangerous.
