We downloaded some APK files and attempted to open them only to encounter the "There was a problem parsing the package" error. So it didn't even make through to the Install screen. However, as it turned out, the files contained malware with a very high probability (according to VirusTotal).

The question is, could it still cause havoc inside the phone even though it didn't go through a proper installation?

If the APK file was not installed this reduces the probability a lot.

The only way I see that could harm a device would be if the file itself would contain an exploit against the Android MediaStore Service. This service processes all files on the internal shared storage sections (/sdcard/ aka /storage/emulated/0).

The Android MediaStore Service has several vulnerabilities since Android 5 where it was included the first time. Video files, picture files and other file formats were affected, but I do not remember that the ZIP format could also be used to trigger an exploit.

It also depends on what Android versions your phone is running and of course what security patch level your device has.

  • Android 9, the latest version according to the update tool. Under `Android security patch level' it says December 1, 2020. Here's an actual VirusTotal scan report, if it helps.

Quite often, whenever there are problems during a download cycle -say, your browser developed a conflict during the download of a particular package, and if the error appeared to resolve itself to the browser, no flag (or notification to the user) would be raised. HOWEVER, if the issue ACTUALLY was not fixed completely, and only appeared to be fixed to the browser, then the likelihood of the app installing correctly is remote. The first sign of such a problem would be exactly what you experienced. "Problem parsing..." This message, by itself, will tell you nothing.

But the answer to your question, in THIS case (download issues), would certainly not do your device any harm. Before even posting the question, you should have done SOME secondary tests, to reveal additional information on the situation. The only way that the conditions you described could damage your device, would be if whatever you downloaded was actually OPENED, after download. The first thing I would check, if concerned about possible damage, would be the source of the error. This can be done by examining whatever WAS downloaded. A simple text editor could try and open whatever is there, if it is complete. If it isn't, it SHOULD be deleted right away.

Other items to check are any other things you downloaded from that source. Since it seems you left everything alone, you should be quite fine. Next time run at least 1 test before beginning to panic ;).
