This mechanism got abused by the Equation group, which was able to download its own firmware to the hard drive of 12 different “categories” (vendors/variations). Functions of this modified firmware remain unknown, but malware on the computer obtains the ability to write and read data to/fro...
As a result, they could be vulnerable to firmware hacking, which leads to malware attaching itself to the firmware and remaining hidden without being detected by antivirus and other security tools. A lack of firmware security can lead to attackers spying on users’ devices, intercepting their ...
Modern businesses are heavily reliant on computers for their operations. Learn the vital role of a firmware update on your business to boost efficiency.
There are several rootkit virus types that give attackers different routes into computers and enable them to steal data from users. 1. Firmware rootkits A firmware rootkit, also known as a hardware rootkit, typically aims to infect a computer’s hard drive and basic input/output system (BIOS)...
A zero-day exploit is a flaw in the software, hardware, or firmware that is unknown to the party or parties responsible for patching the flaw. Advanced Persistent Threats An advanced persistent threat is when an unauthorized user gains access to a system or network and remains there without...
Types of firmware updates Firmware can be categorized by the job it does or the device it supports. For example, you may have a printer firmware update that is designed solely to provide updated security protection against a new virus that has been discoveredtargeting printersas a backdoor into...
Local DNS hijack— attackers install Trojan malware on a user’s computer, and change the local DNS settings to redirect the user to malicious sites. Router DNS hijack— many routers have default passwords or firmware vulnerabilities. Attackers can take over a router and overwrite DNS settings, ...
Firmware rootkits– These rootkits gain access to the software that runs devices, such as routers, network cards, hard drives or system BIOS. Rootkit hypervisors– These rootkits exploit hardware virtualization features to gain control of a machine. This is done by bypassing the kernel and running...
you could flush the cache on your computer and/or router which will clear out any accumulated data and allow for a fresh connection. Additionally, updating your router firmware may be able to help in some cases. Finally, if all else fails then manually editing domain name server records might...
If antivirus software and a boot-time scan fail to remove the rootkit, try backing up your data, wiping your device, and performing a clean install. This is sometimes the only remedy when a rootkit is operating at the boot, firmware, or hypervisor level. For starters, you need to know ...
