Apple began rolling out the latest iOS 16 software update to millions of iPhones last week coinciding with the worldwide availability of the iPhone 14 series. iOS 16 brings with it a number of fresh features such as an interactive lock screen and the ability to edit and unsend recently sent iMessages. But, while many of the new features introduced with iOS 16 aren’t specific to users, the new security feature called “Lockdown” mode offers additional protection to Apple device owners who may be at risk from targeted cyberattacks. But what is the new lockdown mode on the iPhone and what does it do to protect users from cyberespionage tools like Pegasus? We explain Apple’s new iOS 16 security feature.
For years, Apple has marketed its iPhones as the most secured devices on the planet – and it continues to do so. But last year a consortium of journalists published The Pegasus Project, which showed over 30,000 human rights activists, journalists and lawyers across the world, including in India, may have been targeted by Israel-based NSO group’s spyware Pegasus.

The malware did not spare iPhones either and attacked users through a variety of exploits, including several iOS zero-click zero-days. Pegasus allows users to remotely extract a phone’s contents, tap into the camera and microphone and access calls, location information, photographs and messages without their knowledge – and without a victim even clicking on a link.
In September, though, Apple did fix a security hole that Pegasus exploited for installation on iPhones. In November, the United States took strict action by blacklisting the NSO Group, the Israeli company that created Pegasus.

This was followed by a lawsuit filed by Apple against the makers of Pegasus, accusing the NSO Group of “flagrant violations of US federal and state law,” on grounds related to the damage caused by spyware on Apple devices.
Earlier this year, a new report claimed that Pegasus was used to hack the iPhone of a Jordanian journalist in December. The hack occurred several weeks after Apple filed a suit against the Israeli company in a bid to attack its customers.
The Pegasus probe shows that iPhones —or any other ‘connected’ device – are not 100 per cent secure and can potentially be hacked.

What is Lockdown mode?
While Apple still continues to battle against the NSO Group in courts, the company announced a new “lockdown” mode feature as part of the iOS 16 operating system at the Worldwide Developers Conference (WWDC) in June.
Lockdown mode, which is now available with iOS 16 and launching on iPads and Macs later this year, is a security feature which offers an additional layer of security to users who are at risk of being targeted by Pegasus and other sophisticated advanced spyware. Apple calls Lockdown “extreme” and when enabled many of the iPhone features get disabled – a trade-off for such a security feature.
For example, when users temporarily enable Lockdown mode on their phones, it switches off link previews in text messages, which hides a person’s anonymity by obtaining their IP addresses. The feature doesn’t block a link, just the preview, so users can still copy and paste the web address into their browser. Lockdown mode also disables certain features in Safari that might affect some websites.
Certain complex web technologies in your browser, like web-based fonts and just-in-time compilers that help websites load faster, might not render properly or might not load at all. You will notice that when Lockdown mode is turned on, you can’t receive FaceTime calls from contacts if the user has not previously sent the initiator a call or request. You also won’t receive Apple service invitations, like calendars and notes, from those people you haven’t communicated with before while Lockdown Mode is enabled.

How to enable Lockdown mode?
If users think they can be a victim of a spyware attack, they can enable Lockdown Mode on their iPhone running iOS 16, which is rolling out and is free to download. Lockdown mode is located in the Privacy and Security section of the Settings app. Once users select Lockdown Mode, their iPhone will restart and certain functionalities will be unavailable. If you go into Safari, you should see a Lockdown Enabled at the top of the page, indicating that Lockdown Mode is turned on. Since this option is a temporary way to turn off the functionalities of the iPhone that can be abused by hackers, you can switch off Lockdown Mode through the Settings menu, if you wish to do so.

Who should enable Lockdown Mode?
The average person does not really have to worry about someone breaking into their phone and listening to their conversations or surveilling them through their phone cameras. Which is why Lockdown Mode isn’t for everyone. But for journalists, human rights activists, politicians, lawyers and high-ranking officials, Lockdown Mode can make it tough for attackers or spyware makers to hack into an iPhone. While Lockdown Mode is far from fool-proof, it’s a good sign that companies like Apple are taking steps to beef-up security on their devices and protect against malware threats.
