A newly discovered security vulnerability in modern Intel and AMD processors could let remote attackers steal encryption keys via a power side channel attack. Dubbed  Hertzbleed  by a group of researchers from the University of Texas, the University of Illinois Urbana-Champaign, and the University of Washington, the issue is rooted in dynamic voltage and frequency scaling ( DVFS ), a power and thermal management feature employed to conserve power and reduce the amount of heat generated by a chip. "The cause is that, under certain circumstances, periodic CPU frequency adjustments depend on the current CPU power consumption, and these adjustments directly translate to execution time differences (as 1 hertz = 1 cycle per second)," the researchers said. This can have significant security implications on cryptographic libraries even when implemented correctly as  constant-time code  to prevent timing-based side channels, effectively enabling an attacker to leverage t...

A new research has yielded yet another means to pilfer sensitive data by exploiting what's the first "on-chip, cross-core" side-channel attack targeting the ring interconnect used in Intel Coffee Lake and Skylake processors. Published by a group of academics from the University of Illinois at Urbana-Champaign, the  findings  are expected to be presented at the USENIX Security Symposium coming this August. While information leakage attacks targeting the CPU microarchitecture have been previously demonstrated to break the isolation between user applications and the operating system, allowing a malicious program to access memory used by other programs (e.g., Meltdown and Spectre), the new attack leverages a contention on the ring interconnect. SoC  Ring interconnect  is an on-die bus arranged in a ring topology which enables intra-process communication between different components (aka agents) such as the cores, the last level cache (LLC), the graphics unit, and the...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

A newly discovered unpatchable hardware vulnerability in Xilinx programmable logic products could allow an attacker to break bitstream encryption, and clone intellectual property, change the functionality, and even implant hardware Trojans. The details of the attacks against Xilinx 7-Series and Virtex-6 Field Programmable Gate Arrays ( FPGAs ) have been covered in a paper titled " The Unpatchable Silicon: A Full Break of the Bitstream Encryption of Xilinx 7-Series FPGAs " by a group of academics from the Horst Goertz Institute for IT Security and Max Planck Institute for Cyber Security and Privacy. "We exploit a design flaw which piecewise leaks the decrypted bitstream," the researchers said. "In the attack, the FPGA is used as a decryption oracle, while only access to a configuration interface is needed. The attack does not require any sophisticated tools and, depending on the target system, can potentially be launched remotely." The findings wil...

If you own a device, or a hardware component, manufactured by ASUS, Toshiba, Intel, NVIDIA, Huawei, or other 15 other vendors listed below, you're probably screwed. A team of security researchers has discovered high-risk security vulnerabilities in more than 40 drivers from at least 20 different vendors that could allow attackers to gain most privileged permission on the system and hide malware in a way that remains undetected over time, sometimes for years. For sophisticated attackers, maintaining persistence after compromising a system is one of the most important tasks, and to achieve this, existing hardware vulnerabilities sometimes play an important role. One such component is a device driver, commonly known as a driver or hardware driver, a software program that controls a particular type of hardware device, helping it to communicate with the computer's operating system properly. Since device drivers sit between the hardware and the operating system itself and in...

What could be more horrifying than knowing that a hacker can trick the plane's electronic systems into displaying false flight data to the pilot, which could eventually result in loss of control? Of course, the attacker would never wish to be on the same flight, so in this article, we are going to talk about a potential loophole that could allow an attacker to exploit a vulnerability with some level of "unsupervised" physical access to a small aircraft before the plane takes off. The United States Department of Homeland Security's (DHS) has issued an alert for the same, warning owners of small aircraft to be on guard against a vulnerability that could enable attackers to easily hack the plane's CAN bus and take control of key navigation systems. The vulnerability, discovered by a cybersecurity researcher at Rapid 7, resides in the modern aircraft's implementation of CAN (Controller Area Network) bus—a popular vehicular networking standard used in au...

Security researchers have discovered a new class of security vulnerabilities that impacts all major operating systems, including Microsoft Windows, Apple macOS, Linux, and FreeBSD, allowing attackers to bypass protection mechanisms introduced to defend against DMA attacks. Known for years, Direct memory access (DMA)-based attacks let an attacker compromise a targeted computer in a matter of seconds by plugging-in a malicious hot plug device—such as an external network card, mouse, keyboard, printer, storage, and graphics card—into Thunderbolt 3 port or the latest USB-C port . The DMA-based attacks are possible because Thunderbolt port allows connected peripherals to bypass operating system security policies and directly read/write system memory that contains sensitive information including your passwords, banking logins, private files, and browser activity. That means, simply plugging in an infected device, created using tools like Interception , can manipulate the contents o...

Cybersecurity researchers have discovered a way to hide malicious code in Intel SGX enclaves, a hardware-based memory encryption feature in modern processors that isolates sensitive code and data to protect it from disclosure or modification. In other words, the technique allows attackers to implant malware code in a secure memory that uses protection features of SGX which are otherwise designed to protect important data from prying eyes or from being tampered, even on a compromised system. Introduced with Intel's Skylake processors, SGX (Software Guard Extensions) allows developers to run selected application modules in a completely isolated secure region of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels like the operating system, kernel, BIOS, SMM, hypervisor, etc. However, a team of researchers, some of whom were behind the discovery of the Spectre-Meltdown CPU flaws , managed to bypass this protection and g...

We all have something to hide, something to protect. But if you are also relying on self-encrypting drives for that, then you should read this news carefully. Security researchers have discovered multiple critical vulnerabilities in some of the popular self-encrypting solid state drives (SSD) that could allow an attacker to decrypt disk encryption and recover protected data without knowing the password for the disk. The researchers—Carlo Meijer and Bernard van Gastel—at Radboud University in the Netherlands reverse engineered the firmware several SSDs that offer hardware full-disk encryption to identify several issues and detailed their findings in a new paper ( PDF ) published Monday. "The analysis uncovers a pattern of critical issues across vendors. For multiple models, it is possible to bypass the encryption entirely, allowing for a complete recovery of the data without any knowledge of passwords or keys," the researchers say. The duo successfully tested their...

A team of security researchers has discovered another serious side-channel vulnerability in Intel CPUs that could allow an attacker to sniff out sensitive protected data, like passwords and cryptographic keys, from other processes running in the same CPU core with simultaneous multi-threading feature enabled. The vulnerability, codenamed PortSmash (CVE-2018-5407), has joined the list of other dangerous side-channel vulnerabilities discovered in the past year, including Meltdown and Spectre , TLBleed , and Foreshadow . Discovered by a team of security researchers from the Tampere University of Technology in Finland and Technical University of Havana, Cuba, the new side-channel vulnerability resides in Intel's Hyper-Threading technology, the company's implementation of Simultaneous MultiThreading (SMT). Simultaneous MultiThreading is a performance feature that works by splitting up each physical core of a processor into virtual cores, known as threads, allowing each core to...

Security researchers have unveiled details of two critical vulnerabilities in Bluetooth Low Energy (BLE) chips embedded in millions of access points and networking devices used by enterprises around the world. Dubbed BleedingBit , the set of two vulnerabilities could allow remote attackers to execute arbitrary code and take full control of vulnerable devices without authentication, including medical devices such as insulin pumps and pacemakers, as well as point-of-sales and IoT devices. Discovered by researchers at Israeli security firm Armis, the vulnerabilities exist in Bluetooth Low Energy (BLE) Stack chips made by Texas Instruments (TI) that are being used by Cisco, Meraki, and Aruba in their enterprise line of products. Armis is the same security firm that last year discovered BlueBorne , a set of nine zero-day Bluetooth-related flaws in Android, Windows, Linux and iOS that affected billions of devices, including smartphones, laptops, TVs, watches and automobile audi...

A media report today revealed details of a significant supply chain attack which appears to be one of the largest corporate espionage and hardware hacking programs from a nation-state. According to a lengthy report published today by Bloomberg, a tiny surveillance chip, not much bigger than a grain of rice, has been found hidden in the servers used by nearly 30 American companies, including Apple and Amazon. The malicious chips, which were not part of the original server motherboards designed by the U.S-based company Super Micro, had been inserted during the manufacturing process in China. The report, based on a 3-year-long top-secret investigation in the United States, claims that the Chinese government-affiliated groups managed to infiltrate the supply chain to install tiny surveillance chips to motherboards which ended up in servers deployed by U.S. military, U.S. intelligence agencies, and many U.S. companies like Apple and Amazon. "Apple made its discovery of suspi...

A new job opening post on Facebook suggests that the social network is forming a team to build its own hardware chips, joining other tech titans like Google, Apple, and Amazon in becoming more self-reliant. According to the post , Facebook is looking for an expert in ASIC and FPGA—two custom silicon designs to help it evaluate, develop and drive next-generation technologies within Facebook—particularly in artificial intelligence and machine learning. The social media company is seeking to hire an expert who can "an end-to-end SoC/ASIC, firmware and driver development organization, including all aspects of front-end and back-end standard cell ASIC development," reads the job listing on Facebook's corporate website. SoC (system-on-a-chip) is a processor typically used in mobile devices with all the components required to power a device, while ASIC (application-specific integrated circuit) is a customized piece of silicon designed for a narrow purpose that companie...

Don't install Intel's patches for Spectre and Meltdown chip vulnerabilities. Intel on Monday warned that you should stop deploying its current versions of Spectre/Meltdown patches , which Linux creator Linus Torvalds calls 'complete and utter garbage.' Spectre and Meltdown are security vulnerabilities disclosed by researchers earlier this month in many processors from Intel, ARM and AMD used in modern PCs, servers and smartphones (among other devices), which could allow attackers to steal your passwords, encryption keys and other private information. Since last week, users are reporting that they are facing issues like spontaneous reboots and other 'unpredictable' system behaviour on their affected computers after installing Spectre/Meltdown patch released by Intel. Keeping these problems in mind, Intel has advised OEMs, cloud service providers, system manufacturers, software vendors as well as end users to stop deploying the current versions of it...

Do you own an Amazon Echo? So are you also worried about hackers turning out your device into a covert listening device? Just relax, if there's no NSA, no CIA or none of your above-skilled friends after you. Since yesterday there have been several reports on Amazon Echo hack that could allow a hacker to turn your smart speaker into a covert listening device, but users don't need to worry because the hack is not simple, requires physical access to the device and does not work on all devices, as well. Amazon Echo is an always-listening voice-activated smart home speaker that is designed to play music, set alarms, answer questions via the Alexa voice assistant, and control connected smart home devices like WeMo, Hive and Nest. Hack Turns Amazon Echo Into Spying Device (But It's Complex) Now researchers from MWR InfoSecurity have demonstrated a hack, showing how hackers can exploit a vulnerability in some models of Amazon Echo to turn them into covert listening d...

Here's the Raspberry Pi's Christmas treat for tech community! The Raspberry Pi Foundation has released an experimental version of its lightweight Linux-based Debian operating system called PIXEL OS that can run on most standard desktop computers ships with Windows and Mac OS X without the need of a Raspberry Pi. Initially launched in September this year, the PIXEL operating system, stands for "Pi Improved Xwindows Environment, Lightweight," was originally designed to work with Raspberry Pi to turn it into a fully-functional PC. However, Raspberry Pi has now released a version of PIXEL that comes preloaded with a variety of popular tools and can be installed directly on PCs and Mac computers, so you do not have to buy a Raspberry Pi to use PIXEL anymore. "There is a massive installed base of PC and Mac hardware out there, which can run x86 Debian just fine. Could we do something for the owners of those machines?" Raspberry Pi founder Eben Upton s...

Remember Killer USB stick ? A proof-of-concept USB prototype that was designed by a Russian researcher, Dark Purple, last year, to effectively destroy sensitive components of a computer when plugged in. Now, someone has actually created the Killer USB stick that destroys almost anything – such as Laptops, PCs, or televisions – it is plugged into. A Hong Kong-based technology manufacturer is selling a USB thumb drive called USB Kill 2.0 that can fry any unauthorized computer it's plugged into by introducing a power surge via the USB port. It costs $49.95 . How does USB Kill 2.0 work? As the company explains, when plugged in, the USB Kill 2.0 stick rapidly charges its capacitors via the USB power supply, and then discharges – all in a matter of seconds. The USB stick discharges 200 volts DC power over the data lines of the host machine and this charge-and-discharge cycle is repeated several numbers of times in just one second, until the USB Kill stick is removed. ...

We just cannot imagine our lives without smartphones, even for a short while, and NSA whistleblower Edward Snowden had not owned a smartphone since 2013 when he began leaking NSA documents that exposed the government's global surveillance program. Snowden fears that cellular signals of the smartphone could be used to locate him, but now, to combat this, he has designed an iPhone case that would detect and fight against government snooping. With help from renowned hardware hacker Andrew "Bunnie" Huang, Snowden has devised the design, which they refer to as an " Introspection Engine, " that would keep journalists, activists, and human rights workers from being tracked by their own devices leaking their location details. "This work aims to give journalists the tools to know when their smartphones are tracking or disclosing their location when the devices are supposed to be in airplane mode," Huang and Snowden wrote in a blog post published Thu...
