<p>Last week, Jamf Threat Labs published research (https://9to5mac.com/2025/12/22/macsync-stealer-variant-finds-a-way-to-bypass-apple-malware-protections/) on yet another variant of the increasingly popular MacSync Stealer family calling attention to a growing problem in macOS security: malware that’s sneaking around Apple’s most significant third party app protections. This new variant was distributed inside a malicious app that was both code-signed with a valid Developer ID and notarized by Apple, meaning Gatekeeper had no reason to block it from launching. </p>
