Nigeria’s Computer Emergency Response Team (ngCERT) has issued an alert about a new wave of malware, dubbed AdLoad, that is evading Apple’s built-in security measures to hijack browsers and harvest sensitive data from Mac users.
The Nigerian tech security agency says AdLoad is exploiting legitimate system mechanisms to gain deep access to infected macOS devices. Once inside, the malware hijacks browsers, injects intrusive ads, collects user data, and embeds itself across the system using launch agents, login items, and configuration profiles. These techniques enable it to maintain persistence while bypassing routine security checks.
“Detecting AdLoad can be challenging due to its stealthy nature and use of legitimate system mechanisms,” ngCERT says. While manual inspection of login items and system profiles may offer clues, advanced variants often slip past such efforts, it adds.
The advisory underscores a growing reality: Apple devices, often considered more secure than Windows PCs, are increasingly being targeted by cybercriminals. AdLoad’s ability to bypass native protections elevates it from a nuisance to a serious risk, with potential for identity theft, financial fraud, and compromise of sensitive data.
Adload: Rising risks for Apple users
The consequences of infection include browser hijacking, persistent advertising, data theft, degraded performance, and possible deployment as a platform for more severe cyberattacks.
The advisory underscores a growing reality: Apple devices, often considered more secure than Windows PCs, are increasingly being targeted by cybercriminals. AdLoad’s ability to bypass native protections elevates it from a nuisance to a serious risk, with potential for identity theft, financial fraud, and compromise of sensitive data.
With more Nigerians adopting Apple devices for work and personal use, the risks extend beyond individuals. A compromised Mac could serve as an entry point for attackers seeking wider access to corporate networks, amplifying the potential impact on businesses.
How to stay protected
To mitigate exposure, ngCERT recommends:
- Deploying trusted anti-malware tools.
- Keeping macOS and all applications up to date.
- Installing software only from official sources.
- Restricting administrative privileges.
- Implementing endpoint monitoring.
- Training users to spot phishing and fake installers.
- Maintaining regular system backups.
The agency stresses that AdLoad highlights the rising sophistication of macOS malware, making layered defences and timely detection critical to protecting devices and data.
