Security Bite: Here’s what malware your Mac can detect and remove on its own

apple security xprotect mac macos

Ever wonder what malware macOS can detect and remove without help from third-party software? Apple continuously adds new malware detection rules to Mac’s built-in XProtect suite. While most rule names (signatures) are obfuscated, with a bit of reversing engineering, security researchers can map them to their common industry names.

In this edition of 9to5Mac Security Bite, I revisit a story I started working on in May of 2024. Because Apple is continuously adding new modules to its XProtect suite to combat the latest malware trends, I suspect this column will continue to update over time. Here’s what malware your Mac can detect and remove on its own:

Apple currently only able to detect Pegasus spyware in half of infected iPhones

Apple currently only able to detect Pegasus spyware in half of infected iPhones | Close-up of man looking through a spy-hole in a wall

NSO’s Pegasus spyware is one of the most frightening privacy threats an iPhone owner can face. Without you taking any action at all, it’s able to completely take over your phone, accessing almost all of the personal data stored on it, and some versions have been able to activate cameras and microphones.

Pegasus exploits zero-day vulnerabilities – security holes Apple doesn’t yet know about – but the iPhone maker has another way to fight back …

One of the promises of the App Store is that anything you download has gone through a vetting process by Apple. Occasionally though, iPhone apps with malicious code slip through the cracks, and today, researchers at Kaspersky have reported on new malware they discovered in App Store apps—which they say is ‘the first known case.’

Security Bite: Why email security is still so bad

Apple mail app email

It’s a little-known fact that before emails reach your inbox, they pass through a buffer designed to scan and block malicious content. However, over time, email providers—especially Gmail—have shifted their focus to just adding “warning labels” to those with suspicious links or attachments. This approach, best described as “beating around the bush” hasn’t reduced threats much at all. Shockingly, 91% of all cyberattacks still originate from emails. So, what gives?

You’ve heard it time and time again–cybercrime is on an unpredicted rise. This encompasses everything from malware to online scams to intellectual property theft. And if you’re anything like me, it’s increasingly hard to grasp the exponentially climbing figures (hence the title of this week’s column). If the day ends in y, there’s some sort of data leak or hack in the news.

And it is Sunday, after all…

In today’s Security Bite, I want to again shed light on a recent Statista Market Insights survey that predicts the annual cost of cybercrime globally will reach $10.29 trillion by 2025. For perspective, that’s more than one-third of the United States’ GDP, which sits at $25.44 trillion as of writing.

Security researchers have identified an attempt by state-sponsored hackers from North Korea (DPRK) to target Mac users with infostealer malware through a trojanized meeting app.

Once infected, the malware would establish a connection between the Mac and the attacker’s command and control (C2) server to exfiltrate sensitive data like iCloud Keychain credentials. It was also found to quietly install the remote desktop application AnyDesk and keylogging software in the background to take over machines and collect keystrokes.

Kaspersky, the renowned Russian cybersecurity firm, made headlines at this time last year after uncovering an attack chain using four iOS zero-day vulnerabilities to create a zero-click exploit.

How small & medium businesses can stop Mac malware in its tracks

Mac malware Cthulhu Stealer

Some of us are old enough to remember the days when malware was strictly a Windows problem. Macs were more secure by design, but another key factor was that there weren’t enough of them in use to make Mac malware a sensible use of time for attackers.

With Macs now very much a mainstream choice for consumers and businesses alike, they’ve also become a far more attractive target for cybercriminals – and Mac malware is a real and growing problem …
