The WiFi chip encrypts network traffic and holds the current WiFi credentials, thereby providing the attacker with further information.” Threat actors can execute code by exploiting an unpatched or new security issue over-the-air, or abusing the local OS firmware update mechanism. ” concludes the paper. Pierluigi Paganini.
This attack relies on a client-server architecture and consists of using other protocols such as TCP or SSH to tunnel malware through DNS requests. DNS Encryption: DoH vs. DoT. To combat DNS attacks, major companies such as Google have pushed forward DNS encryption over TLS (DoT) or HTTPS (DoH). DNS tunneling.
The findings of the study reveal a number of serious security issues, including the use of hard-coded credentials, and an insecure firmware update process. We later managed to extract the firmware from the EEPROM for further static reverse engineering. Further hardware analysis of the circuit board helped us identify chips.
United Extensible Firmware Interface (UEFI). UEFI is a specification for the firmware that controls the first stages of booting up a computer, before the operating system is loaded. (It’s Windows 11 comes ready to embrace the impressively-named Pluton TPM architecture.
The same rings true for encryption and authentication. Asymmetric encryption may require too much processing power for certain devices, making symmetric keys the only option. Over-the-air (OTA) software and firmware updates must be delivered securely and effectively. weak cryptography, software bugs, malware, etc.).
This report includes an analysis of the ISaGRAF framework, its architecture, the IXL and SNCP protocols that are used to program and control ISaGRAF-based devices and to communicate with them. Since authentication data is encrypted with a preset symmetric key, the attacker could decrypt an intercepted target (device) password.
firmware (hard drives, drivers, etc.), However, some patches, particularly for infrastructure, firmware, or less common software may not be automatable. While this eliminates many headaches, it does not scan for misconfigurations and may not support other critical updates such as IT infrastructure (routers, firewalls, etc.),
In our previous blog post , we discussed the challenges for securing IoT deployments, and how businesses and consumers benefit from authenticating and validating IoT software and firmware updates. Requirements also included that the firmware was to be signed by the manufacturer and verified by the pacemaker.

It comes equipped with a built-in TOR network tunnel for communication with command servers, along with update and delivery functionality through trusted services such as GitLab, GitHub, and Bitbucket, all using custom encrypted archives. This architectural approach is a hallmark of APT malware.
Its table illustration also goes into more detail and notes Google’s responsibility for hardware, boot, hardened kernel and interprocess communication (IPC), audit logging, network, and storage and encryption of data. Also read: Exfiltration Can Be Stopped With Data-in-Use Encryption, Company Says.
Currently, there are two technologies that attempt to address this use-case – homomorphic encryption and secure enclaves. While homomorphic encryption has great promise, the practical implementations are limited to very niche solutions that can tolerate additional compute-intensive overhead. Encryption. The Pitfalls.
Digital identification would fulfill a critical element of attaining a zero trust architecture, especially important for industrial technology edge devices. Secure firmware flashing is also a way to enhance assurance of device security, allowing for audit capabilities and controls around these devices. Encryption Key Management.
Even fewer (19%) told Proofpoint that they had updated their Wi-Fi router’s firmware. These are foundational principles to design next generation security architectures. Encryption. Encryption Key Management. A fifth of survey participants said that they never use it or activated it only when there was no other option.
Secure Browsing Access: Connections between users and the internet often will be encrypted using HTTPS connections, making inspection difficult or operationally burdensome for firewalls and other monitoring. End-to-End Encryption: The largest organizations need to deploy additional resources to protect against data theft.
“With a cyberattack, it’s more than just data that needs protecting—at risk is really the entire physical infrastructure from applications and operating systems down to low-level firmware and BIOS. Druva’s metadata-centric architecture supports management and security of data in the cloud with long-term retention, and regulatory compliance.
SD-WAN is a virtual architecture for managing a wide-area network covering distributed, hybrid IT environments typical for today’s enterprise organizations. With SD-WAN architectures, branch employees and remote users connect to an enterprise network through a web of connected devices over the internet. What is SD-WAN?
Many organizations have opted to converge their IT and OT environments, which can yield many benefits such as efficiency and more elegant architecture; at the same time, these decisions are not without risk. These often use proprietary network protocols and lack basic security controls like authentication or encryption. Conclusion.
Brute-force attacks on services that use SSH, a more advanced protocol that encrypts traffic, can yield similar outcomes. User files were encrypted, with the device’s interface displaying a ransom note demanding payment of 0.03 Cybercriminals seek exploits for zero-day vulnerabilities in IoT devices. BTC to recover the data.
History lesson: i386 is a 32-bit CPU architecture, maybe more widely known by the name x86. It was the CPU architecture of the first generations of Intel Pentium, AMD K6, and Athlon. Starting in 2003, a 64-bit version of the x86 architecture appeared, usually named x86-64 (or amd64 in Debian-based Linux distributions).

government and others, we are still no closer to seeing zero trust architecture widely adopted. I am very surprised that the cyber insurance industry has not required zero trust architecture already, but perhaps the $1.4 Encryption needs to be done for the environment, and that means that key management is another very complex process.
However, instead of encrypting the data, it purposefully destroyed it in the affected systems. The attackers will not just encrypt data; they will destroy it, posing a significant threat to organizations vulnerable to politically driven attacks. They attribute the wiper, named SwiftSlicer, to Sandworm (aka Hades).
Their report is a good starting point for diving deep into the MBUX internals and understanding the architecture of the system.
