New Bluetooth Flaw Let Hackers Take Over Android, Linux, macOS, and iOS Devices

New Bluetooth Flaw Let Hackers Take Over Android, Linux, macOS, and iOS Devices

Dec 07, 2023 Mobile Security / Vulnerability
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

Warning for iPhone Users: Experts Warn of Sneaky Fake Lockdown Mode Attack

Dec 05, 2023 Mobile Security / Spyware
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's New "Lockdown Mode" Protects iPhone, iPad, and Mac Against Spyware

Jul 07, 2022
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 Photos; a

A SaaS Security Challenge: Getting Permissions All in One Place

A SaaS Security Challenge: Getting Permissions All in One Place 

May 08, 2024Attack Surface / SaaS Security
Permissions in SaaS platforms like Salesforce, Workday, and Microsoft 365 are remarkably precise. They spell out exactly which users have access to which data sets. The terminology differs between apps, but each user's base permission is determined by their role, while additional permissions may be granted based on tasks or projects they are involved with. Layered on top of that are custom permissions required by an individual user.  For example, look at a sales rep who is involved in a tiger team investigating churn while also training two new employees. The sales rep's role would grant her one set of permissions to access prospect data, while the tiger team project would grant access to existing customer data. Meanwhile, special permissions are set up, providing the sales rep with visibility into the accounts of the two new employees. While these permissions are precise, however, they are also very complex. Application admins don't have a single screen within these applications th
