Hackers Target Mac Crypto Users With The New notnullOSX Malware

If you use a Mac computer and hold cryptocurrency, there is a new threat to watch out for. A malicious software called notnullOSX is targeting Apple systems.

The operation relies on tricking you into handing over complete system control without triggering alarms. Fake error screens trick you into pasting malicious terminal commands The attack starts with a fake protected Google document. The page shows a fake encryption error and pushes you to fix it. The first method uses a trick called ClickFix. The fake page tells you to open your computer terminal and paste a specific command. If you do this, a hidden script downloads the malware in the background. The second method uses a normal-looking disk image file. Hackers even set up a fake website for a wallpaper app to trick people into downloading the file. The software manipulates you into granting full disk access manually Apple designed its security framework to stop random apps from reading your private files.

One tool replaces legitimate wallet software with a fake version designed to steal your passwords.
