M1 Macs face first recorded malware Adware has emerged that runs natively on M1 Macs - and it won't be the last By Stephan Wiesend | 19 Feb 21 It was probably only a matter of time. As the security specialist Patrick Wardle reports, the first adware for M1 Macs has been recorded. The malware, based on the adware Pirri and known as GoSearch22, was specially compiled for Apple's ARM platform and makes unwanted adverts display. The malware, first reported to the antivirus platform VirusTotal in December, was called GoSearch22 and was even signed with a developer certificate from Apple. (Apple has since withdrawn this certificate, so the malware would no longer be executable.)
