ReiKey is just the latest app released under the Objective-See brand of Mac security and privacy apps. Nonetheless, because it’s a free app, it’s a solid alternative for Mac users who can’t afford a full-blown antivirus. Users should be aware that ReiKey doesn’t detect all types of macOS keyloggers, as some of these might be using other methods for recording keystrokes. Screenshots of these features and more are available below: Users can trigger the on-demand all-system scan from the ReiKey icon (by clicking the “Scan…” option), or they can use ReyKey from the command-line. ReiKey doesn’t require special permissions to work.If the app installs an event tap for which it doesn’t have a reason to do so, then the user should either look into the app’s features for an explanation or consider using an alternative app.īy default, ReiKey runs all the time in the OS’ background and listens to newly registered event taps, but it can also scan a system on demand for any processes that have already installed a CoreGraphics keyboard event tap. Wardle already released the ReiKey 1.1 version that allows to instructs ReiKey to flag as benign some specific applications, like Apple ones. The scan results will also include legitimate entries, so users need to carefully analyze them. the type of keyboard event tap either “passive listener” or “active filter”.the target of the event tap (which is normally global, for all processes).the process that installed the keyboard event tap.The scan provided the users the following information: The tool scans for existing keyboard “event taps” and alerts whenever a new keyboard event tap is activated. In other words its goal is generically detect (the most common type of) macOS keyloggers.” “ReiKey was designed to detect such keyboard taps, alerting you anytime a new tap is installed. “The majority of macOS malware that contains keylogger logic (to capture keypresses) does so via CoreGraphics ‘event taps.'” states the post published by Wardle. Note that tool is effective only against keylogger that installs install CoreGraphics keyboard “event taps, but there are other way to implement keylogging features. Grab version 1.1.0: /jhJDAnRsYUĪccording to Wardle, most macOS keyloggers rely on ‘event taps’ implemented in the CoreGraphics framework to capture keystrokes, for this reason, the expert developed the tool to detect any new tap event that is added to the system. ReiKey generically detects macOS (CG event tap) keyloggers □⌨️ The application is able to detect malicious codes that uses the CoreGraphics framework to monitor event taps. ReiKey was developed by the popular macOs expert and former NSA white hat hacker Patrick Wardle. The ReiKey app monitor systems for applications that analyzed keyboard ‘ event taps‘ to monitor and filter input events from several points within the system intercept keystrokes.Įvent taps are added by both malicious applications and legitimate software to manage inputs provided by the user. Good news for macOS users, a new open source tool dubbed ReiKey allows them to detect Mac Keyloggers. ReiKey is a free tool that allows to scan and detect keylogger that install persistent keyboard “event taps” to intercept your keystrokes.
