A balance between security and privacy

Lock mode is a security feature that hopes to prevent your device from being compromised Zero Day Gaps. As a result of its restrictive nature, using the lock mode leaves something of a fingerprint that can reveal who is using it.

Electronic Frontier Foundation (EFF) a statement Cover Your Tracks web fingerprint tool can detect when an iPhone owner has been using Lock Mode due to restrictions in the Safari browser.

EFF explained that Lockdown Mode limits potential entry points that could become targets for spyware and other malware authors. One of them is the ability to load custom fonts, which can be used to exploit the web browser’s rendering engine. EFF notes that it is easy to use JavaScript to detect whether or not a font is blocked.

Together with the browser user agent And other device information left when visiting a webpage, EFF has been able to confirm that the iPhone owner is actually using Lockdown mode. The concern here is that it could draw a target on an individual’s back, drawing attention not to the information left behind but to the way Lockdown Mode attempts to secure their device.

This illustrates one drawback of using Lock mode in that it betrays user privacy in an effort to enhance overall security. EFF continues to say that “Apple’s introduction of this powerful new protection is a welcome development for those who need it most” but that “users should also be aware of what information they view on the web” if they choose to switch it over.
