For years, Mac computers have been heralded as some of the most secure consumer devices on the market. Apple’s robust security architecture, combined with a historically smaller market share compared to Windows, helped macOS remain relatively unscathed by widespread cyber threats. However, as macOS adoption continues to rise, cybercriminals are taking notice, developing increasingly sophisticated attacks to exploit potential vulnerabilities.

The reality is clear: owning a Mac does not equate to absolute security. With evolving threats and vulnerabilities, proactive defence is now more crucial than ever.

Emerging Mac Security Concerns

Mac-specific malware is becoming more sophisticated, often bypassing traditional security measures. One of the latest threats, the Banshee macOS Stealer, infiltrates systems by masquerading as legitimate software through phishing sites. Once installed, it harvests sensitive data such as browser credentials, passwords, and cryptocurrency wallets.

Originally sold for $3,000 on underground forums, its leaked source code in November 2024 made detection slightly easier, but the incident highlights the ever-present risks of credential theft and phishing-based attacks. As more cybercriminals gain access to advanced malware tools, Mac users can no longer afford to rely solely on macOS’s built-in defences.

2. System Integrity Protection (SIP) Vulnerabilities

Apple's System Integrity Protection (SIP) is designed to prevent malicious software from altering core system files. However, security researchers discovered critical vulnerabilities that allow attackers with root access to bypass SIP protections.

One such flaw, identified as CVE-2024-44243, enabled attackers to install malicious kernel drivers, creating persistent malware that could evade detection and compromise system reliability. Apple patched this vulnerability in macOS Sequoia 15.2, reinforcing the necessity of keeping systems up to date​.


3. Exploitation of Zero-Day Vulnerabilities

Zero-day vulnerabilities remain one of the most dangerous threats to macOS security. These exploits allow attackers to breach systems before Apple can issue a patch.

In December 2024, Apple released emergency updates to fix two critical zero-day flaws—CVE-2024-44308 and CVE-2024-44309—which allowed attackers to execute arbitrary code and perform cross-site scripting attacks via malicious web content. This incident highlights the importance of staying on top of security updates and being cautious when browsing online

Proactive Measures for Mac Users

Given the increasing threats targeting macOS, users must take a proactive approach to security. Here’s how you can strengthen your defences:


1. Keep macOS Updated

Apple frequently releases security patches to address newly discovered vulnerabilities. Ensure that your Mac is always running the latest version of macOS by enabling automatic updates.


2. Download Software Only from Trusted Sources

Avoid downloading applications from unverified sources. Stick to the Mac App Store or reputable developers to minimise the risk of installing malware-laden software.


3. Enable Built-in macOS Security Features

Leverage macOS’s native security tools:

  • Gatekeeper: Blocks untrusted applications from running.

  • XProtect: Apple’s built-in malware scanner automatically detects and removes known threats.

  • FileVault: Encrypts your data to prevent unauthorised access.


4. Use Additional Security Tools

  • Reputable Antivirus Solutions: While Macs are less prone to traditional viruses, security software can help detect and block malware.

  • Password Managers: Securely store and manage passwords to reduce the risk of credential theft.

  • Two-factor Authentication (2FA): Adds an extra layer of security to your Apple ID, email, and other critical accounts.


5. Be Wary of Phishing Scams

Phishing remains one of the most effective attack methods. Be cautious of unexpected emails, messages, or pop-ups requesting personal information. Never click on suspicious links, and verify URLs before entering your credentials.


Final Thoughts

macOS may be one of the most secure operating systems available, but as cyber threats evolve, so must user awareness and defences. The assumption that "Macs don’t get viruses" is not only outdated but also dangerous in today’s cybersecurity landscape.

By staying informed, adopting best security practices, and leveraging Apple’s built-in protections alongside additional security measures, Mac users can significantly reduce their risk of falling victim to cyberattacks.
