System Security
WhatsYourSign
objective-seeWhatsYourSign adds a menu item to Finder.app. Simply right-, or control-click on any file to display its cryptographic signing information!
TaskExplorer
objective-seeVisually explore all running tasks (processes) ....viewing its signature status, loaded dylibs, open files, network connection, and much more.
RansomWhere
objective-seeA general-purpose ransomware detector. It watches for file encryption behaviour and blocks and prompts when a process starts encrypting files in bulk, working without signatures so unknown ransomware is covered too. It suits people who want an extra layer of protection for important files.
OverSight
objective-seeOverSight monitors a mac's mic and webcam, alerting the user when the internal mic is activated, or whenever a process accesses the webcam.
LuLu
objective-seeA free, open-source firewall for macOS. It prompts for every program that tries to reach the network so you can allow or block it, remembers the choice as a rule and supports a silent mode. It suits people who want control over which apps get online without paying for a firewall.
KnockKnock
objective-seeLike AutoRuns, but for macOS. It lists everything that starts automatically, stays resident or runs on a schedule — login items, launch agents, kernel extensions, browser plugins — with signing and origin details, so you can see what is running on its own. It suits investigating unexpected startup items and security audits.
DylibHijackScanner
objective-seeScans the computer for apps vulnerable to dylib hijacking or already hijacked. It inspects how apps load dynamic libraries for paths that could be substituted, listing risky entries and confirmed hits, which suits security self-checks or investigating a suspected malicious library.
BlockBlock
objective-seeProvides ongoing protection by watching persistence locations. When something tries to install itself as a login item or background component, it asks whether to allow it, which helps surface persistence planted silently. It suits people who want to know if their system is being modified behind their back.
