Millions of Android Devices Using Broadcom Wi-Fi Chip Can Be Hacked Remotely

Millions of Android Devices Using Broadcom Wi-Fi Chip Can Be Hacked Remotely

Jul 07, 2017
Google has released its latest monthly security update for Android devices, including a serious bug in some Broadcom Wi-Fi chipsets that affects millions of Android devices, as well as some iPhone models. Dubbed BroadPwn , the critical remote code execution vulnerability resides in Broadcom's BCM43xx family of WiFi chipsets, which can be triggered remotely without user interaction, allows a remote attacker to execute malicious code on targeted Android devices with kernel privileges. "The most severe vulnerability in this [runtime] section could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of an unprivileged process," Google describes in the July 2017 Android Security Bulletin. The BroadPwn vulnerability ( CVE-2017-3544 ) has been discovered by Exodus Intelligence researcher Nitay Artenstein, who says the flawed Wi-Fi chipset also impacts Apple iOS devices. Since Artenstein will be presenting his finding at

Millions Of Smartphones Using Broadcom Wi-Fi Chip Can Be Hacked Over-the-Air

Apr 05, 2017
Millions of smartphones and smart gadgets, including Apple iOS and many Android handsets from various manufacturers, equipped with Broadcom Wifi chips are vulnerable to over-the-air hijacking without any user interaction. Just yesterday, Apple rushed out an emergency iOS 10.3.1 patch update to address a serious bug that could allow an attacker within same Wifi network to remotely execute malicious code on the Broadcom WiFi SoC (Software-on-Chip) used in iPhones, iPads, and iPods. The vulnerability was described as the stack buffer overflow issue and was discovered by Google's Project Zero staffer Gal Beniamini, who today detailed his research on a lengthy blog post , saying the flaw affects not only Apple but all those devices using Broadcom's Wi-Fi stack. Beniamini says this stack buffer overflow issue in the Broadcom firmware code could lead to remote code execution vulnerability, allowing an attacker in the smartphone's WiFi range to send and execute code on th

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.
