Ghost ransomware actors, identified as operating from China, have been targeting unpatched systems and stolen credentials to infiltrate networks, encrypt data, and demand ransom payments. Patching and vulnerability management Apply timely security updates to operating systems, software, and firmware.
Much of the industry still relies on legacy operational tech (OT) systems that lack modern security features such as automated patch management and encryption by default. Additionally, a distributed workforce, ranging from remote maintenance technicians to cabin crews, multiplies entry points for social-engineering tactics like phishing.
First vulnerability (CVE-2024-4947) The heart of every web browser is its JavaScript engine. The JavaScript engine of Google Chrome is called V8 — Google’s own open-source JavaScript engine. We started reverse engineering the game’s code and discovered that there was more content available beyond this start menu.
While details remain sparse, reports suggest social engineering tactics like phishing, SIM swapping, and multi-factor authentication (MFA) fatigue attacks may have been used to infiltrate systems. Once inside, they’ll likely have used other methods to successfully bypass enterprise security tools.
Using this script, UDS commands can be easily distinguished from the regular network traffic of communication between the diagnostic software and hardware: We examined the diagnostic tool interface and decoded the traffic, which allowed us to find various UDS commands, such as for resetting the ECU, turning off the engine, and locking the doors.

Interesting research: " Self-encrypting deception: weaknesses in the encryption of solid state drives (SSDs) ": Abstract: We have analyzed the hardware full-disk encryption of several SSDs by reverse engineering their firmware. We conclude that one should not rely solely on hardware encryption offered by SSDs.
The only way to protect against BLURtooth attacks is to control the environment in which Bluetooth devices are paired, in order to prevent man-in-the-middle attacks, or pairings with rogue devices carried out via social engineering (tricking the human operator). However, patches are expected to be available at one point.
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 encryption system implemented by popular solid-state drives (SSDs) is affected by critical vulnerabilities that could be exploited by a local attacker to decrypt data. “We have analyzed the hardware full-disk encryption of several SSDs by reverse engineering their firmware.
With the default configuration of these printers, it’s possible to retrieve these credentials in an encrypted format without authenticating to the printer. A vulnerability in the encryption process of these credentials means that you can decrypt them with responses from the web interface. This is the IV for the encryption algorithm.
Encryption scrambles data to make it unreadable to those without decryption keys. Proper use of encryption preserves secrecy and radically lowers the potential damage of a successful cybersecurity attack. Encryption algorithm types will provide an overview of the mathematical algorithms used to encrypt data (AES, RSA, etc.),
The CVE-2019-0090 vulnerability affects the firmware running on the ROM of the Intel’s Converged Security and Management Engine (CSME). Intel CSME is responsible for initial authentication of Intel-based systems by loading and verifying all other firmware for modern platforms.” x, SPS_E3_05.00.04.027.0. .
Microsoft experts have disclosed a series of vulnerabilities in the firmware of Netgear routers which could lead to data leaks and full system takeover. The traffic was TLS-encrypted, so the researchers focused on the router and investigate the presence of security weaknesses that can be exploited by threat actors.
Security researchers have found a way to extract a global encryption key that was hardcoded in the CPUs of several Siemens programmable logic controller (PLC) product lines, allowing them to compromise their secure communications and authentication.
QNAP forces its customers to update the firmware of their Network Attached Storage (NAS) devices to protect against the DeadBolt ransomware. QNAP forced the firmware update for its Network Attached Storage (NAS) devices to protect its customers against the DeadBolt ransomware. ” states the vendor.

Conclusion, always do your homework before putting your hands on the target: FCC database, Google, and Chinese search engines are your best friend when doing a hardware hacking research! This will help me later in the case I will be able to obtain a firmware that eventually is encrypted (i.e. known-plaintext attack).
At the time, the Maze ransomware operators only released three screenshots as proof of the data breaches on the Maze ransomware leak site: Researchers from ZDNet who analyzed the leaked data confirmed that it included source code for the firmware of various LG products, including phones and laptops.

However, even with the best planning, organizations can find a few users, machines, or systems that were overlooked or whose backup may be corrupted or encrypted. How Does Ransomware Encryption Work? Ransomware encryption works like any other encryption. The file extensions of the encrypted files will also provide a clue.
The leak was first published by Till Kottmann, a Swiss software engineer, who manage a very popular Telegram channel on data leak. The engineering received the files from an anonymous hacker who claimed to have hacked the company earlier this year, the experts believe that this leak is just a first lot on a larger collection.
