Hitachi Energy vulnerabilities
CISA has published two advisories describing vulnerabilities in Hitachi Energy products.

Apple improvements for malware detection
Apple security expert Patrick Wardle reported that upcoming versions of macOS will make it easier for security products to detect when a piece of malware may be trying to bypass Transparency Consent and Control (TCC), the framework that manages access to sensitive user data on macOS. In most cases, macOS malware bypasses TCC by tricking the user into clicking a button to allow a TCC exception. In order to allow security products to detect potential TCC attacks, Apple is adding TCC events to the Endpoint Security system. Some issues identified in the beta version of macOS still need to be addressed, but Wardle is hopeful.
