Attackers target macOS’ Gatekeeper Vulnerability to infiltrate OSX/Linker Malware

Intego Security researcher, Joshua Long, has analyzed an OSX/Linker virus. It is being developed to target the recently discovered macOS Gatekeeper Security flaw. This vulnerability, disclosed by Filippo Cavallarin, allows a malicious binary downloaded from the Internet to bypass Gatekeeper’s Scanning process. The researcher wrote upon his discovery in May, “On MacOS X version <= 10.14.5 (at time of writing) it is possible to easily bypass Gatekeeper in order to execute untrusted code without any warning or user’s explicit permission,” For your information, it is in Gatekeeper’s design to accept both the external drives and network shares as safe location which allows apps to run smoothly. However, putting these two features, it is possible to deceive the GateKeeper. How the vulnerability based attack work? It is believed that the attackers crafted a zip file and send it to a targeted system. Users download it because of lack of knowledge. The Read more
