kernel exploit | Breaking Cybersecurity News | The Hacker News

A fully functional jailbreak has been released for the latest iOS 12.4 on the Internet, making it the first public jailbreak in a long time—thanks to Apple. Dubbed " unc0ver 3.5.0 ," the jailbreak works with the updated iPhones, iPads and iPod Touches by leveraging a vulnerability that Apple previously patched in iOS 12.3 but accidentally reintroduced in the latest iOS version 12.4. Jailbreaking an iPhone allows you to install apps and other functions that are usually not approved by Apple, but it also disables some system protections that Apple put in place to protect its users, opening you up to potential attacks. Usually, iPhone Jailbreaks are sold for millions of dollars by exploit brokers, but if you want to jailbreak your Apple device, you can do it for free. An anonymous researcher who goes by the online alias "Pwn20wnd" has released a free jailbreak for iOS 12.4 on GitHub that exploits a use-after-free vulnerability in iOS kernel responsibly repor

UPDATE: Researchers have finally disclosed complete technical details of two kernel side-channel attacks, Meltdown and Spectre — which affect not only Intel but also systems and devices running AMD, ARM processors —allowing attackers to steal sensitive data from the system memory. ____________ The first week of the new year has not yet been completed, and very soon a massive vulnerability is going to hit hundreds of millions of Windows, Linux, and Mac users worldwide. According to a blog post published yesterday, the core team of Linux kernel development has prepared a critical kernel update without releasing much information about the vulnerability. Multiple researchers on Twitter  confirmed that Intel processors (x86-64) have a severe hardware-level issue that could allow attackers to access protected kernel memory, which primarily includes information like passwords, login keys, and files cached from disk. The security patch implements kernel page-table isolation (KP

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

Wishing you all a very 'belated' Merry Christmas. This holiday season Santa has a very special gift for all PlayStation gamers. Developer SpecterDev finally released a fully-functional much-awaited kernel exploit for PlayStation 4 (firmware 4.05) today—almost two months after Team Fail0verflow revealed the technical details of it. Now available on Github , dubbed "namedobj," the kernel exploit for the PlayStation 4 on 4.05FW allows users to run arbitrary code on the gaming console, enabling jailbreaking and kernel-level modifications to the system. Although PS4 kernel exploit does not include Jailbreak code, others can develop a full jailbreak exploit using it. Jailbreaking allows users to run custom code on the console and install mods, cheats, third-party applications, and games that are typically not possible because of the anti-piracy mechanisms implicated on the Sony PlayStation. "This release, however, does not contain any code related to def
