Dell Releases A New Cybersecurity Utility To Detect BIOS Attacks

Dell Releases A New Cybersecurity Utility To Detect BIOS Attacks

April 14, 2020Wang Wei
Computer manufacturing giant Dell has released a new security tool for its commercial customers that aims to protect their computers from stealthy and sophisticated cyberattacks involving the compromise of the BIOS. Dubbed ' SafeBIOS Events & Indicators of Attack ' (IoA), the new endpoint security software is a behavior-based threat detection system that alerts users when BIOS settings of their computers undergo some unusual changes. BIOS (Basic Input Output System) is a small but highly-privileged program that handles critical operations and starts your computer before handing it over to your operating system. Protecting the BIOS program is crucial because: Changes to the system BIOS settings could allow malicious software to run during the boot process, Once a hacker takes over the BIOS, he can stealthily control the targeted computer and gain access to the data stored on it, Malware in BIOS remains persistent and doesn't get away even when you format or

Cybersecurity Researchers Spotted First-Ever UEFI Rootkit in the Wild

September 27, 2018Swati Khandelwal
Cybersecurity researchers at ESET have unveiled what they claim to be the first-ever UEFI rootkit being used in the wild, allowing hackers to implant persistent malware on the targeted computers that could survive a complete hard-drive wipe. Dubbed LoJax , the UEFI rootkit is part of a malware campaign conducted by the infamous Sednit group, also known as APT28, Fancy Bear , Strontium , and Sofacy , to target several government organizations in the Balkans as well as in Central and Eastern Europe. Operating since at least 2007, Sednit group is a state-sponsored hacking group believed to be a unit of GRU (General Staff Main Intelligence Directorate), a Russian secret military intelligence agency. The hacking group has been associated with a number of high profile attacks, including the DNC hack just before the U.S. 2016 presidential election . UEFI, or Unified Extensible Firmware Interface, a replacement for the traditional BIOS, is a core and critical firmware component of a

Millions of Up-to-Date Apple Macs Remain Vulnerable to EFI Firmware Hacks

" Always keep your operating system and software up-to-date ." This is one of the most popular and critical advice that every security expert strongly suggests you to follow to prevent yourself from major cyber attacks. However, even if you attempt to install every damn software update that lands to your system, there is a good chance of your computer remaining outdated and vulnerable. Researchers from security firm Duo Labs analysed over 73,000 Macs systems and discovered that a surprising number of Apple Mac computers either fails to install patches for EFI firmware vulnerabilities or doesn't receive any update at all. Apple uses Intel-designed Extensible Firmware Interface (EFI) for Mac computers that work at a lower level than a computer's OS and hypervisors—and controls the boot process. EFI runs before macOS boots up and has higher-level privileges that, if exploited by attackers, could allow EFI malware to control everything without being detecte
Oops! Microsoft Accidentally Leaks Backdoor Keys to Bypass UEFI Secure Boot

Oops! Microsoft Accidentally Leaks Backdoor Keys to Bypass UEFI Secure Boot

August 10, 2016Swati Khandelwal
It's True  —  There is no such backdoor that only its creator can access. Microsoft has accidentally leaked the Secret keys that allow hackers to unlock devices protected by UEFI ( Unified Extensible Firmware Interface ) Secure Boot feature. What's even worse? It will be impossible for Microsoft to undo its leak. Secure Boot is a security feature that protects your device from certain types of malware, such as a rootkit, which can hijack your system bootloader, as well as, Secure Boot restricts you from running any non-Microsoft operating system on your device. In other words, when Secure Boot is enabled, you will only be able to boot Microsoft approved ( cryptographically signature checking ) operating systems. However, the Golden Keys disclosed by two security researchers, using alias MY123 and Slipstream , can be used to install non-Windows operating systems, say GNU/Linux or Android, on the devices protected by Secure Boot. Moreover, according to the blog pos

Last Week someone just hacked the infamous Hacking Team , The Italy-based cyber weapons manufacturer and leaked a huge trove of 400GB internal data , including: Emails Hacking tools Zero-day exploits Surveillance tools Source code for Spyware A spreadsheet listing every government client with date of purchase and amount paid Hacking Team is known for its advanced and sophisticated Remote Control System (RCS) spyware , also known as Galileo , which is loaded with lots of zero-day exploits and have ability to monitor the computers of its targets remotely. Today, Trend Micro security researchers found that the Hacking Team " uses a UEFI  (Unified Extensible Firmware Interface)  BIOS Rootkit to keep their Remote Control System (RCS) agent installed in their targets' systems ." That clearly means, even if the user reinstalls the Operating System, formats the hard disk, and even buys a new hard disk, the agents are implanted after Microsoft Windows is
