New 5G Modem Flaws Affect iOS Devices and Android Models from Major Brands

New 5G Modem Flaws Affect iOS Devices and Android Models from Major Brands
Dec 08, 2023 Vulnerability / Mobile Network
A collection of security flaws in the firmware implementation of 5G mobile network modems from major chipset vendors such as MediaTek and Qualcomm impact USB and IoT modems as well as hundreds of smartphone models running Android and iOS. Of the 14 flaws – collectively called  5Ghoul  (a combination of "5G" and "Ghoul") – 10 affect 5G modems from the two companies, out of which three have been classified as high-severity vulnerabilities. "5Ghoul vulnerabilities may be exploited to continuously launch attacks to drop the connections, freeze the connection that involve manual reboot or downgrade the 5G connectivity to 4G," the researchers  said  in a study published today. As many as 714 smartphones from 24 brands are impacted, including those from Vivo, Xiaomi, OPPO, Samsung, Honor, Motorola, realme, OnePlus, Huawei, ZTE, Asus, Sony, Meizu, Nokia, Apple, and Google. The vulnerabilities were disclosed by a team of researchers from the ASSET (Automated

MIT Researchers Discover New Flaw in Apple M1 CPUs That Can't Be Patched

MIT Researchers Discover New Flaw in Apple M1 CPUs That Can't Be Patched
Jun 11, 2022
A novel hardware attack dubbed  PACMAN  has been demonstrated against Apple's M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages "speculative execution attacks to bypass an important memory protection mechanism, ARM Pointer Authentication, a security feature that is used to enforce pointer integrity," MIT researchers Joseph Ravichandran, Weon Taek Na, Jay Lang, and Mengjia Yan  said  in a new paper. What's more concerning is that "while the hardware mechanisms used by PACMAN cannot be patched with software features, memory corruption bugs can be," the researchers added. The vulnerability is rooted in pointer authentication codes ( PACs ), a line of defense introduced in arm64e architecture that aims to detect and secure against unexpected changes to  pointers  — objects that reference an address location in memory. PACs aim to solve a common problem in software

NVIDIA Jetson Chipsets Found Vulnerable to High-severity Flaws

NVIDIA Jetson Chipsets Found Vulnerable to High-severity Flaws
Jun 22, 2021
U.S. graphics chip specialist NVIDIA has released  software updates  to address a total of 26 vulnerabilities impacting its Jetson system-on-module (SOM) series that could be abused by adversaries to escalate privileges and even lead to denial-of-service and information disclosure. Tracked from CVE‑2021‑34372 through CVE‑2021‑34397, the flaws affect products Jetson TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, and Nano and Nano 2GB running all Jetson Linux versions prior to 32.5.1. The company credited Frédéric Perriot of Apple Media Products for reporting all the issues. The  NVIDIA Jetson  line consists of embedded Linux AI and computer vision compute modules and developer kits that primarily caters to AI-based computer vision applications and autonomous systems such as mobile robots and drones. Chief among the vulnerabilities is CVE‑2021‑34372 (CVSS score: 8.2), a buffer overflow flaw in its  Trusty  trusted execution environment (TEE) that could result in informatio

What's the Right EDR for You?

What's the Right EDR for You?
May 10, 2024Endpoint Security / Threat Detection
A guide to finding the right endpoint detection and response (EDR) solution for your business' unique needs. Cybersecurity has become an ongoing battle between hackers and small- and mid-sized businesses. Though perimeter security measures like antivirus and firewalls have traditionally served as the frontlines of defense, the battleground has shifted to endpoints. This is why endpoint detection and response (EDR) solutions now serve as critical weapons in the fight, empowering you and your organization to detect known and unknown threats, respond to them quickly, and extend the cybersecurity fight across all phases of an attack.  With the growing need to defend your devices from today's cyber threats, however, choosing the right EDR solution can be a daunting task. There are so many options and features to choose from, and not all EDR solutions are made with everyday businesses and IT teams in mind. So how do you pick the best solution for your needs? Why EDR Is a Must Because of
