![]() Some conspire that the NSA is behind many of the kernel vulnerabilities present in the OS X kernel, but that's just thoughts and speculations derived from (possibly) false rumours.Īnyway, I'll throw a few links and sources below and you can read some more 'in-depth' stuff if you're willing to. It is actually still being developed as a proof of concept, along with some other experimental malware for OS X, but at its current stage (version 2) it is able to travel via thunderbolt storage devices and infect other Macs. The same exploit will almost certainly never work on both Windows and Macs.Īn experimental (very rare) kernel infection exists for the Mac, called In any case, if you manage to infect the Mac with a Windows harddisk, or the other way around, the actual malware will be different. See this question on security.stackexchange. So, when a user opens an app with this flag, the Gatekeeper will check if the app came from a trusted developer or not. The way the Gatekeeper works is by setting the Quarantine Flag when the file gets downloaded. It's possible that a Windows machine contains such files on a harddisk which can attack a Mac, as soon as the Mac user decides to open these files. macOS has two malware protection mechanisms: Gatekeeper and XProtect. ![]() The same is the case for java files, several text document formats, some image formats, etc. Following best practices for securing your device and using built-in security features can help, but antivirus software can serve to protect your device even further. Adobe Acrobat, or Flash Player, the file can use flaws in the host program to make the host program install and execute a virus. Mac computers are not immune to malware and Mac-targeted attacks are increasingly prevalent. If the file has to be opened by a host program e.g. Infected Windows executables are harmless on a Mac, and infected Mac executables are harmless on a Windows machine. Windows executables cannot run on a Mac and Mac executables cannot run on Windows, so a Windows executable cannot infect a Mac. app, it contains code that is run on the machine if a user tells the computer to do so. There are 2 ways in which files on a disk can infect a computer: Actually, there is indeed a low but very real chance to get infected.
