Lockdown Mode | Breaking Cybersecurity News | The Hacker News

A critical Bluetooth security flaw could be exploited by threat actors to take control of Android, Linux, macOS and iOS devices. Tracked as  CVE-2023-45866 , the issue relates to a case of authentication bypass that enables attackers to connect to susceptible devices and inject keystrokes to achieve code execution as the victim. "Multiple Bluetooth stacks have authentication bypass vulnerabilities that permit an attacker to connect to a discoverable host without user confirmation and inject keystrokes," said security researcher  Marc Newlin , who  disclosed  the flaws to the software vendors in August 2023. Specifically, the attack deceives the target device into thinking that it's connected to a Bluetooth keyboard by taking advantage of an "unauthenticated pairing mechanism" that's defined in the Bluetooth specification. Successful exploitation of the flaw could permit an adversary in close physical proximity to connect to a vulnerable device and trans...

A new "post-exploitation tampering technique" can be abused by malicious actors to visually deceive a target into believing that their Apple iPhone is running in Lockdown Mode when it's actually not and carry out covert attacks. The novel method, detailed by Jamf Threat Labs in a  report  shared with The Hacker News, "shows that if a hacker has already infiltrated your device, they can cause Lockdown Mode to be 'bypassed' when you trigger its activation." In other words, the goal is to implement Fake Lockdown Mode on a device that's compromised by an attacker through other means, such as  unpatched security flaws  that can trigger execution of arbitrary code. Lockdown Mode , introduced by Apple last year with iOS 16, is an  enhanced security measure  that aims to safeguard high-risk individuals from sophisticated digital threats such as mercenary spyware by  minimizing the attack surface . What it doesn't do is prevent the execution of mali...

Apple on Wednesday announced it plans to introduce an enhanced security setting called  Lockdown Mode  in iOS 16, iPadOS 16, and macOS Ventura to safeguard high-risk users against "highly targeted cyberattacks." The "extreme, optional protection" feature, now available for preview in beta versions of its upcoming software, is designed to counter a surge in threats posed by private companies developing state-sponsored surveillanceware such as  Pegasus ,  DevilsTongue ,  Predator , and  Hermit . Lockdown Mode, when enabled, "hardens device defenses and strictly limits certain functionalities, sharply reducing the attack surface that potentially could be exploited by highly targeted mercenary spyware," Apple  said  in a statement. This includes blocking most message attachment types other than images and disabling link previews in Messages; rendering inoperative just-in-time ( JIT ) JavaScript compilation; removing support for shared albums in ...
