how to easily spoof a user’s password
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:
