Apple users warned of high-tech Mac malware that steals personal data, goes undetected for months – here’s how to stay safe

About 100 million Apple users are at risk of falling victim to malware.

Cybersecurity software company Check Point issued an urgent warning to millions of Mac users around the world who may be affected by malicious actors who circumvent the devices’ built-in antivirus systems.

According to the company, cybercriminals have developed malware, called Banshee macOS Stealer, which stealthily steals credentials and other sensitive data while running undetected for over months.

The malware first surfaced last year in what Check Point calls “underground forums” and was billed as a “stealer-as-a-service” that was available to purchase for as little as $3,000. With it, cybercriminals can target Mac users with malware through phishing sites masquerading as popular software companies like Chrome and Telegram, the company reported.

In the fall, it was discovered that “Banshee macOS Stealer” was modified by developers using code “stolen” from Apple XProtect, an antivirus system built into Mac devices, which allowed the malware to go undetected on user computers.

“This stealthy malware doesn’t just infiltrate; it operates undetected, blending seamlessly with normal system processes while stealing browser credentials, cryptocurrency wallets, user passwords, and sensitive file data,” Check Point researchers wrote.

“What makes the Banshee truly alarming is its ability to evade detection. Even seasoned IT professionals struggle to identify its presence.”

After the malware’s source code was leaked to online forums in November, antivirus systems were better able to detect it, but it also raised fears of new cybercriminal tactics.

“While macOS includes robust security features such as Gatekeeper, XProtect, and sandboxing, the rise of the Banshee thief serves as a reminder that no operating system is immune to threats,” the researchers wrote.

To protect yourself and your data, tech news site Tom’s Guide advised users to “be vigilant” of downloadable apps and software by verifying the company’s legitimacy before downloading.

While Macs come with built-in antivirus software, the experts at Tom’s Guide recommended “using it in conjunction” with other antivirus software, which can be purchased, as well as a VPN and password manager.
