This is a dumb crypto mistake I had not previously encountered: A developer says it was possible to run their own software on the car infotainment hardware after discovering the vehicle’s manufacturer had secured its system using keys that were not only publicly known but had been lifted from programming examples. […].
In a public GitHub repository committed in December of that year, someone working for multiple US-based device manufacturers published what’s known as a platform key, the cryptographic key that forms the root-of-trust anchor between the hardware device and the firmware that runs on it.
Recent progress has sparked discussions, but current capabilities are still far from threatening encryption standards like 2048-bit RSA. It is essential to understand the risks posed by quantum computing, as future advancements could compromise today's encrypted data, opening new opportunities for threat actors.
The attack requires physical access to the computer, but it's pretty devastating : On Thunderbolt-enabled Windows or Linux PCs manufactured before 2019, his technique can bypass the login screen of a sleeping or locked computer -- and even its hard disk encryption -- to gain full access to the computer's data.
Ensure remote workers are more secure by following these five tips: Change the Default Password: Routers should have the manufacturer default password updated the moment it’s turned on and connected. Update the Firmware: Router manufacturers are constantly issuing updates and patches for newly discovered firmware vulnerabilities.
As a rule, this means that the source code of the device’s firmware is unavailable and all the researcher can use is the user manual and a few threads on some user forum discussing the device’s operation. The vulnerability assessment of IoT/IIoT devices is based on analyzing their firmware.
I also looked at custom firmware and soldering and why, to my mind, that was a path I didn't need to go down at this time. Let's got through the options: Firmware Patching I'll start with the devices themselves and pose a question to you: can you remember the last time you patched the firmware in your light globes? Or vibrator.

The malicious code specifically targets QNAP NAS devices manufactured by Taiwanese company QNAP, it already infected over 62,000 QNAP NAS devices. These are encrypted with the actor’s public key and sent to their infrastructure over HTTPS. The QSnatch malware implements multiple functionalities, such as: .
A pivotal moment came when the FBI obtained over 7,000 decryption keys, allowing victims to unlock their encrypted data for free. Despite these setbacks, LockBit attempted to maintain its operations, quickly adapting by changing encryption methods and shifting its leak site strategy.
Manufacturers need a scalable solution to address concerns like authentication, data encryption, and the integrity of firmware on connected devices. Security in IoT devices has lagged behind their production. The post Securing the IoT at Scale: How PKI Can Help appeared first on Keyfactor.
From backdoors- As the Korean giant creates, validates and manufactures its computing devices all on its own, its every piece of hardware, wiring and firmware is securely drafted at its high secure R&D plants & factories in the world.
NAS servers are a privileged target for hackers because they normally store large amounts of data.The ransomware was targeting poorly protected or vulnerable NAS servers manufactured by QNAP, threat actors exploited known vulnerabilities or carried out brute-force attacks.
While the statement does not reveal a lot of tangible information, this snippet is important: “MSI urges users to obtain firmware/BIOS updates only from its official website, and not to use files from sources other than the official website.” Stop malicious encryption. Among them are household names like Lenovo and HP.
BleepingComputer also reported that dozens of ransom notes and encrypted files have been submitted to the ID-Ransomware service by affected QNAP users. Up to date apps and firmware seem not to help either.” The malicious code appends.encrypt extension to filenames of encrypted files.
In response, manufacturers are intensifying their cybersecurity efforts, incorporating advanced CI/CD workflows to safeguard medical devices from escalating attacks. New security solutions are now aiding healthcare organizations' IT teams in promptly resolving issues, even with devices from various manufacturers.
Security experts from security firm SEC Consult have identified over 100 companies that buy and re-brand video surveillance equipment (surveillance cameras, digital video recorders (DVRs), and network video recorders (NVRs)) manufactured by the Chinese firm Hangzhou Xiongmai Technology Co., Xiongmai hereinafter) that are open to hack.
