North Korean hackers use disguised apps to target Macs with hidden malware

Macs are safer than Windows PCs, but they’re not foolproof. Hackers occasionally find ways to infect Apple devices, and in most cases, we’re the ones who allow it. Since infiltrating Apple’s App Store is difficult, hackers trick people into downloading apps from third-party stores or random websites.

These apps look legitimate but are actually tools for infecting devices with malicious software. A recent incident highlights this issue, with North Korean hackers targeting Macs by hiding malware in seemingly harmless macOS apps.

How does the malware work?

Recent discoveries by Jamf Threat Labs have unveiled a sneaky form of malware targeting macOS computers. While it may sound technical, understanding the basics of how this malware operates can help you stay safe online.

This malware hides in seemingly harmless applications, such as a game called Minesweeper and a note-taking app referred to as a Notepad. These apps function as expected, but behind the scenes, they run malicious programs that could allow hackers to take control of your computer.

The apps use a technology called Flutter, a tool often used to create apps that work on multiple devices like phones and computers. Flutter makes it easier for app developers to design their software, but its unique structure also helps hackers hide their malicious code, making it harder for experts to detect.

Once installed, the malware connects to a remote server (think of it as a command center for hackers) to receive instructions. These instructions could include running commands on your computer without your knowledge. One trick this malware uses is running AppleScripts, a type of script built for macOS systems, which can quietly execute commands to steal your data or even control your device.

Even scarier, some versions of this malware had been signed and approved by Apple’s security system before experts caught on. This means the hackers were testing how far they could push their schemes without raising suspicion.
