The domain name system (DNS) is basically a directory of addresses for the internet. Your browser uses DNS to find the IP for a specific service. For example, when you enter esecurityplanet.com, the browser queries a DNS service to reach the matching servers, but it’s also used when you send an email. DNS spoofing or poisoning.
Unified Extensible Firmware Interface (UEFI) is a specification that defines the architecture of the platform firmware used for booting the computer hardware and its interface for interaction with the operating system. ” states CERT/CC. . ” states CERT/CC.
The botnet leverages a robust architecture based on a combination of third-party services, P2P, and Command & Control servers. This architecture was implemented to make the botnet resilient to takedowns by law enforcement and security firms with the support of the vendors of the infected devices.
This archive is discreetly hosted on legitimate websites, cleverly disguised as firmware binaries for enigmatic devices labeled “m100” The Bitbucket repository was created on June 21, 2018, under the account of Julie Heilman, and it remains the sole repository associated with this profile. onion ghtyqipha6mcwxiz[.]onion
50,000 DDoS attacks on public domain name service (DNS) resolvers. 553% increase in DNS Flood attacks from 1H 2020 to 2H 2023. DDoS attacks on single networks or websites render them unavailable, but DDoS attacks on DNS resolvers bring down all networks and websites using that DNS resource.
See translation Will buy 0day/1day RCE in IoT Escrow See translation Hi, I want to buy IoT exploits with devices located in Korea Any architecture There are also offers to purchase and sell IoT malware on dark web forums, often packaged with infrastructure and supporting utilities.
While we were unable to obtain the same results by analyzing the CERT-UA samples, we subsequently identified a different WhiteBlackCrypt sample matching the WhisperKill architecture and sharing similar code. In December we were made aware of a UEFI firmware-level compromise through logs from our firmware scanning technology.
To enable wireless support, we need to find: The kernel Wi-Fi modules that need to be in the initramfs (Depends on hardware) The Wi-Fi firmware files that need to be in the initramfs (Depends on hardware) The Wireless interface name (Kali defaults to: wlan0 ) Additional packages to increase functionally. bin firmware: brcm/brcmfmac*-sdio.*.txt
Similarly, spoofed domain name system (DNS) and IP addresses can redirect users from legitimate connections to dangerous and malicious websites. Additional protection may be deployed using browser security, DNS security, or secure browsers to protect endpoints from malicious websites.
and installed software (operating systems, applications, firmware, etc.). Web browsing security manages internal or local domain name service (DNS), secure web gateways (SWGs), firewall settings, and other techniques, tools, and protocols used to block dangerous or unwanted websites and URLs.
We have also added support for the Raspberry Pi 400’s wireless card, however it is very important to note that this is not a nexmon firmware, as nexmon does not currently support it. kali3-amd64 NOTE: The output of uname -r may be different depending on the system architecture.

To provide a secure foundation, we’re extending hardening and the use of memory-safe languages to low-level firmware (including in Trusty apps ). In this blog post, we'll show you how to gradually introduce Rust into your existing firmware , prioritizing new code and the most security-critical code.

Posted by Ivan Lozano and Roger Piqueras Jover Android’s defense-in-depth strategy applies not only to the Android OS running on the Application Processor (AP) but also the firmware that runs on devices. This post covers how to use two high-value sanitizers which can prevent specific classes of vulnerabilities found within the baseband.
