I’ve posted some frequently used Freda scripts. Honestly, I like cordshares, but sometimes I need them(raw script, link, etc…).

Bypass root(codeshare)

frida --codeshare dzonerzy/fridantiroot -f

Bypass disabled Debug

setTimeout(function() {
    Java.perform(function() {
        console.log("");
        console.log("[.] Debug check bypass");

        var Debug = Java.use('android.os.Debug');
        Debug.isDebuggerConnected.implementation = function() {
            //console.log('isDebuggerConnected Bypassed !');
            return false;
        }

    });
}, 0);

Bypass SSL Pinning

Java.perform(function() {
    var array_list = Java.use("java.util.ArrayList");
    var ApiClient = Java.use('com.android.org.conscrypt.TrustManagerImpl');
    ApiClient.checkTrustedRecursive.implementation = function(a1, a2, a3, a4, a5, a6) {
        // console.log('Bypassing SSL Pinning');
        var k = array_list.$new();
        return k;
    }
}, 0);

iOS 10&11 Bypass SSL Pinning

if (tls_helper_create_peer_trust)
{
MSHookFunction((void *) tls_helper_create_peer_trust, (void *) replaced_tls_helper_create_peer_trust, (void **) &original_tls_helper_create_peer_trust);
}
}

else if ([processInfo respondsToSelector:@selector(isOperatingSystemAtLeastVersion:)] && [processInfo isOperatingSystemAtLeastVersion:(NSOperatingSystemVersion){10, 0, 0}])
{
// Support for iOS 10
void *tls_helper_create_peer_trust = dlsym(RTLD_DEFAULT, "tls_helper_create_peer_trust");
MSHookFunction((void *) tls_helper_create_peer_trust, (void *) replaced_tls_helper_create_peer_trust, (void **) &original_tls_helper_create_peer_trust);
