I’m unsure where this topic would best fit, so I’d appreciate it if the moderators could move it if necessary. Consider a scenario where a Mac becomes infected with malware.
While it’s relatively rare, it’s certainly not out of the question. One concern that arises is whether this malware could potentially spread to other Macs connected to the same network or even to nearby devices through Bluetooth, even if those Macs are using separate iCloud accounts.
In general, malware requires specific vectors to propagate from one device to another. On a local network, certain types of malware might exploit vulnerabilities in network protocols or services that are running on connected devices.
However, this would typically require the malware to have certain capabilities or access levels that could allow it to discover and exploit other systems. Regarding Bluetooth, while it is technically possible for malware to spread this way, it usually depends on certain conditions being met, such as having a device set to be discoverable and the right exploits to carry out the attack.
When devices are using separate iCloud accounts, this might limit the extent to which the malware can control or access shared resources but does not completely eliminate the risk of contribution or interaction. In summary, while the spread of malware from one Mac to another on the same network or via Bluetooth is theoretically possible, it would generally depend on specific circumstances.
Keeping systems updated and exercising caution with downloads can significantly reduce such risks.
