Newly-Discovered Malware Targets Unpatched MacOS Flaw

Researchers have discovered never-before-seen Mac malware samples, which they believe are being developed to target a recently-disclosed vulnerability in the MacOS operating system.

The vulnerability, a bypass that was disclosed in May and has yet to be patched by Apple, exists in the MacOS Gatekeeper security feature, which verifies downloaded applications before allowing them to run on Macs.  Researchers now say that they have spotted new samples of malware, dubbed OSX/Linker, which they claim are being developed to target the vulnerability.

While researchers said that it is unclear whether any of the malware samples are part of an active campaign, they suspect that the samples are being developed for an imminent exploitation of the vulnerability.
