ElcomSoft, the Russian computer security, cracking encrypted passwords in the system and pass successfully broken iOS 4 is specialized encryption hardware. After about 20 minutes a password to encrypt all data on your iPhone, ElcomSoft, in other words, now has a tool that passwords, lists of calls, surfing history, photographs, access to the geographical movements - and even deleted files. This tool can be purchased by the intelligence and legal organizations.
The good news is that ElcomSoft technique requires physical access to your iPhone, iPhone or iPod touch. The bad news is, if the attacker - the government also has access to the installation of the iTunes encryption cracked almost immediately.
But how Apple ElcomSoft crack AES-256 encryption standard? The secret, as glorious jailbreak geohot for PlayStation 3, depending on the hardware-level attacks. AES-256 is standard in the industry, because it is almost impossible to brute force - but by ElcomSoft, the attack on the encrypted data encryption chip to attack. IOS data on the device 4 are encrypted with a password of a 4-digit code, which means that it is possible to only 10,000 key is derived. ElcomSoft then uses hardware encryption chip itself, the key by brute force, which lasts approximately 20 minutes. If the key is derived, is a complete file system is exposed and can be closed using standard tools, such as access to information and legal advice FTK.
Help key escrow, nor are authentication keys "in" so that iTunes can connect to the deployment and back, and even brute-force password. A process that provides relatively simple and seems to be no guarantees, but no further details ElcomSoft - storage of keys is easily IOS device has a unique key device (UID), storing files available on iTunes. These buttons are used to access the same file as a password.
Should you be worried? No - If you think the government reason to decode the iPhone. While breaking the encryption is relatively simple, the phone file systems for analyzing the copy take hours. If the phone is physically secure grip - as "disappear" for several hours not only seem to put in your pocket - there is no reason why he should be worried. If you are paranoid type, but it is necessary to completely remove iTunes from the system [Windows / Mac]. In addition, you can disable simple password, set a password for your IOS device. If your 8-digit code, and iTunes, you can never be sure that the data on your iPhone, iPod touch or iPhone to always be safe.
