AI-Powered Mac Malware: The Rising Threat in 2024

AI-Powered Malware Development Reshapes Mac Security Landscape

In a concerning development for Mac users, cybersecurity experts are warning of a significant increase in sophisticated macOS malware created with the help of generative AI. Moonlock's 2024 Threat Report reveals that publicly available AI tools like ChatGPT are enabling hackers to overcome technical barriers and create malicious software more quickly and efficiently 1

AI Lowers the Entry Barrier for Cybercriminals

The report highlights a case involving a Russian-speaking threat actor known as 'barboris,' who admitted to building macOS malware without any prior coding experience, thanks to generative AI. Using natural language prompts, barboris created an infostealer capable of targeting Keychain credentials and cryptocurrency wallet information 1

Mykhailo Pazyniuk, Malware Research Engineer at Moonlock, stated, "We expect a surge in the variety of stealers targeting macOS in 2025," emphasizing that threat actors are focusing on users as the weakest link in the attack chain 1

The Rise of Malware-as-a-Service (MaaS)

Alongside AI-powered development, the rise of malware-as-a-service (MaaS) has made macOS malware more accessible than ever. The darknet has seen a surge in discussions around bypassing macOS defenses and distributing MaaS in 2024 2

Cyber gangs like AMOS now operate as highly profitable MaaS businesses, where malware developers create the software, and affiliates with less technical knowledge pay to access and deploy the malicious packages. This model has significantly lowered the entry barrier for cybercriminals, with services that previously cost tens of thousands now available for around $1,500 per month 2

Evolving Threat Landscape

The macOS threat landscape has shifted from traditional adware and ransomware to more sophisticated "Stealers" – malware designed to quietly gather sensitive data. Notable examples include:

1. Cthulhu Stealer: Discovered in August 2024, this malware disguised itself as legitimate software to trick users into downloading and installing it 3

   .

3. HZ Remote Access Tool (HZ RAT): Discovered in September 2024, this malware granted attackers full administrative control over infected systems and established persistent access 3

Implications and Recommendations

The notion that macOS is inherently safe from cyberattacks is now outdated. Users are advised to treat macOS like any other internet-connected device by keeping software updated, downloading apps only from trusted sources, and installing reputable third-party security tools 1

Experts emphasize the importance of user vigilance, as social engineering remains the most common entry point for attacks. Users should be wary of handing out sensitive information and scrutinize every pop-up and prompt, even on macOS 3
