Question

I’m developing some iPhone application and I’m very frustrated when some of my applications published on hacked app resources. And anyone can install those apps for free.

So my question is: How to protect application from dumping into memory, running in debug mode and making hacked ipsw bundle? Is there source examples for that?

Answer 1

i found this source snippet as example of isCracked function

#if HEARTBEAT_CHECK_PIRACY
+ (BOOL)isCracked {
#if TARGET_IPHONE_SIMULATOR
    return NO;
#else
    static BOOL isCracked = NO;
    static BOOL didCheck = NO;
    if(didCheck) return isCracked;

#if HEARTBEAT_PIRACY_THRESHOLD >= 1
    if([[[NSBundle mainBundle] infoDictionary] objectForKey:@"SignerIdentity"] != nil) {
        #if HEARTBEAT_PIRACY_THRESHOLD >= 2
        NSString* infoPath = [[NSBundle mainBundle] pathForResource:@"Info" ofType:@"plist"];
        if([[NSString stringWithContentsOfFile:infoPath encoding:NSUTF8StringEncoding error:NULL] rangeOfString:@"</plist>"].location != NSNotFound) {
            #if HEARTBEAT_PIRACY_THRESHOLD >= 3
            NSDate* infoModifiedDate = [[[NSFileManager defaultManager] fileAttributesAtPath:infoPath traverseLink:YES] fileModificationDate];
            NSDate* pkgInfoModifiedDate = [[[NSFileManager defaultManager] fileAttributesAtPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"PkgInfo"] traverseLink:YES] fileModificationDate];
            if([infoModifiedDate timeIntervalSinceReferenceDate] > [pkgInfoModifiedDate timeIntervalSinceReferenceDate]) {      
            #endif
        #endif
                isCracked = YES;
        #if HEARTBEAT_PIRACY_THRESHOLD >= 2
            #if HEARTBEAT_PIRACY_THRESHOLD >= 3
            }
            #endif
        }
        #endif
    }   
#endif

    didCheck = YES;

    return isCracked;
#endif
}
#endif
