New Mac Malware Exploits GateKeeper Bypass Bug that Apple Left Unpatched

New Mac Malware Exploits GateKeeper Bypass Bug that Apple Left Unpatched

Jun 25, 2019
Cybersecurity researchers from Intego are warning about possible active exploitation of an unpatched security vulnerability in Apple's macOS Gatekeeper security feature details and PoC for which were publicly disclosed late last month. Intego team last week discovered four samples of new macOS malware on VirusTotal that leverage the GateKeeper bypass vulnerability to execute untrusted code on macOS without displaying users any warning or asking for their explicit permission. However, the newly discovered malware, dubbed OSX/Linker , has not been seen in the wild as of now and appears to be under development. Though the samples leverage unpatched Gatekeeper bypass flaw, it does not download any malicious app from the attacker's server. According to Joshua Long from Intego, until last week, the "malware maker was merely conducting some detection testing reconnaissance." "One of the files was signed with an Apple Developer ID (as explained below), it is
Apple's Mac OS X Still Open to Malware, Thanks Gatekeeper

Apple's Mac OS X Still Open to Malware, Thanks Gatekeeper

Jan 16, 2016
Apple Mac Computers are considered to be much safer than Windows computers at keeping out the viruses and malware, but the new Exploit discovered by researchers again proves it indeed quite false. Last year, The Hacker News reported a deadly simple exploit that completely bypassed one of the core security features in Mac OS X known as Gatekeeper . Apple released a patch in November, but now the same security researcher who discovered the original Gatekeeper bypass vulnerability said he found an equally obvious workaround. Patrick Wardle, ex-NSA staffer and head of research at security intelligence firm Synack, said the security patch released by Apple was " incredibly weak " and that the update was " easy to bypass " in minutes. Gatekeeper's Failure Once Again Introduced in July of 2012, Gatekeeper is Apple's anti-malware feature designed to block untrusted, dodgy apps from running, keeping Mac OS X systems safe from malware.

6 Ways to Simplify SaaS Identity Governance

6 Ways to Simplify SaaS Identity Governance

Feb 21, 2024SaaS Security / Identity Management
With SaaS applications now making up the vast majority of technology used by employees in most organizations, tasks related to identity governance need to happen across a myriad of individual SaaS apps. This presents a huge challenge for centralized IT teams who are ultimately held responsible for managing and securing app access, but can't possibly become experts in the nuances of the native security settings and access controls for hundreds (or thousands) of apps. And, even if they could, the sheer volume of tasks would easily bury them. Modern IT teams need a way to orchestrate and govern SaaS identity governance by engaging the application owners in the business who are most familiar with how the tool is used, and who needs what type of access.  Nudge Security is a  SaaS security and governance solution  that can help you do just that, with automated workflows to save time and make the process manageable at scale. Read on to learn how it works. 1 . Discover all SaaS apps used b
Deadly Simple Exploit Bypasses Apple Gatekeeper Security to Install Malicious Apps

Deadly Simple Exploit Bypasses Apple Gatekeeper Security to Install Malicious Apps

Oct 01, 2015
Apple Mac Computers are considered to be invulnerable to malware, but the new Exploit discovered by security researchers proves it indeed quite false. Patrick Wardle , director of research at security firm Synack , has found a deadly simple way that completely bypass one of the core security features in Mac OS X i.e.  Gatekeeper . Introduced in July of 2012, Gatekeeper is Apple's anti-malware feature designed to keep untrusted and malicious applications from wreaking havoc on Macs. However, Wardle has found a quick and simple way to trick Gatekeeper into letting malicious apps through on Mac OS X machines, even if the protection is set to open apps downloaded only from the Mac App Store. According to the researcher, before allowing any apps to execute on an OS X machine, Gatekeeper performs a number of checks, such as: Checking the initial digital certificate of a downloaded app Ensuring the app has been signed with an Apple-recognized developer certificat
