Facebook Hacks Points To Much Bigger Threat For Mobile Developers

DavidGilbert99 writes "Facebook admitted last weekend that it was hacked but assured everyone that no data was compromised. However following some investigation by security firm F-Secure, it seems this could be just the tip of the iceberg and that thousands of mobile app developers without the dedicated security team Facebook has in place could already be compromised. The vector for the attack was a mobile developer's website, and the malware used likely targeted Apple's Mac OS X rather than Windows."
