Final month, the corporate added 74 new Yara detection guidelines to macOS, probably the most I’ve ever seen. These assist forestall malware from executing or spreading by checking for particular patterns that match recognized malware signatures or behaviors.

So, why is Mac changing into extra focused? Right here’s what I’m gathering.

Macs are rising in reputation, each for private and enterprise use. With this, they’re shedding their energy in low numbers and changing into a extra enticing goal for cybercriminals.

Furthermore, the rise in malware-as-a-service (MaaS) can also be an enormous contributor.
