After a lengthy court battle, the Federal Bureau of Investigation bought a hacking tool from another company and successfully unlocked the iPhone, although it didn't recover anything of significance.
Just like the FBI, Turkish officials hope to uncover further evidence on the attacker's iPhone that might help them track down potential collaborators.
The case follows the San Bernardino shooting where Apple refused to help the Federal Bureau of Investigation unlock a work phone used by one of the killers.
Reports from Turkish media claim that Apple has been asked to help unlock an iPhone belonging to the Russian ambassador's assassin. For instance, Naked Security noted that with the iPhone 4s default settings, anyone could use Siri to bypass the lock screen with a certain verbal command, even if it's locked with a passcode.
The Russian government is reportedly sending a technical team to Turkey to try and unlock the phone - as local law enforcement attempts to break into the device have, so far, been unsuccessful, AppleInsider reported.
What's important to note, however, is that the iPhone 4s should be easier to hack given the fact that it's not featuring the advanced encryption systems that are available on the latest iPhone models. Apple says creating a backdoor could fall into the wrong hands and be potentially unsafe.
Though Turkey has asked Apple to help unlock the phone, seeing past events it seems unlikely that the company will be willing to assist. The company refused, however, citing its security policy. He was assasinated by a faux-bodyguard while giving a speech at an art gallery in Ankara.
The off-duty police officer Mevlut Mert Altintas shot the Russian ambassador to Ankara, Andrei Karlov, several times in a awful crime witnessed by many people on live TV last Monday, in a well-known art gallery in Ankara, Turkey.
