Spoofing or phishing – presenting a user with fake authentication requests – is a common email tactic, but it’s not the only vector where you need to be on your guard. Every version of macOS is vulnerable to a very simple phishing attack right on your desktop that doesn’t require admin privileges to run, would not be detected by GateKeeper or XProtect, and which could easily be placed on your mac by any of the nefarious malware / adware installer scripts that come with some less reputable software downloads.
This attack isn’t new, but it’s not often talked about. The easiest way to see how it works is in this quick 4-minute demo:
As you can see, it’s easy to grab the icon of any Application and put it in the script; it doesn’t even have to be the icon of an app that’s running. The simple demo I gave above could easily launch iTunes first to increase the coherence of the attack, or it could use a completely different icon, including the icon of security programs you may have running on your mac.
How can you check?
If you were presented with a password request like this and wanted to check whether it’s legitimate or not, an easy way would be to use my free utility DetectX Swift’s Profiler. Click the Profiler function, and search for ‘osascript’ within the Running Processes section. Note how DetectX Swift shows you the text of the script being run, confirming that this dialog is up to no good:
It’s been unusually quiet on Applehelpwriter these past few months, and the reason is that I’ve been devoting all my time and efforts to the new version of DetectX. The new version is called DetectX Swift because (yeah, you guessed it) I wrote it in Swift and because it’s considerably faster than its older sibling.
DetectX Swift’s got a new interface, but there’s far more going on under the hood. The Search uses some fancy heuristics as well as hard-coded and live update search definitions to ensure it provides the very best in security threat scanning.
The new Profile view employs some super cool dynamic highlighting and lets you inspect the contents not only of directories but also of scripts, plists and other files that could execute troublesome code on your mac.
There’s changes in the History view, too, both in the display and functions. One of the coolest things I like about the new History function is that you can run a diff on any previous run against the latest run, immediately seeing how they differ.
There’s tons more to DetectX Swift, but the best way to find out about it is just to try it. The beta version is free to use for both Home and Commercial users, so just head off over to its home page and grab yourself a copy!
Don’t forget to keep us informed of how it goes. The beta is still in an early stage and more features are slated as it develops, but feel free to tell us about anything that you feel could be done better or things that you’d like to see added.
Share and enjoy! 🙂
