Huge Flaws Affect Nearly Every Modern Device; Patch Could Hit CPU Performance

Huge Flaws Affect Nearly Every Modern Device; Patch Could Hit CPU Performance
Jan 03, 2018
UPDATE: Researchers have finally disclosed complete technical details of two kernel side-channel attacks, Meltdown and Spectre — which affect not only Intel but also systems and devices running AMD, ARM processors —allowing attackers to steal sensitive data from the system memory. ____________ The first week of the new year has not yet been completed, and very soon a massive vulnerability is going to hit hundreds of millions of Windows, Linux, and Mac users worldwide. According to a blog post published yesterday, the core team of Linux kernel development has prepared a critical kernel update without releasing much information about the vulnerability. Multiple researchers on Twitter  confirmed that Intel processors (x86-64) have a severe hardware-level issue that could allow attackers to access protected kernel memory, which primarily includes information like passwords, login keys, and files cached from disk. The security patch implements kernel page-table isolation (KP

Unpatched Windows Kernel Bug Could Help Malware Hinder Detection

Unpatched Windows Kernel Bug Could Help Malware Hinder Detection
Sep 18, 2017
A 17-year-old programming error has been discovered in Microsoft's Windows kernel that could prevent some security software from detecting malware at runtime when loaded into system memory. The security issue, described by enSilo security researcher Omri Misgav, resides in the kernel routine "PsSetLoadImageNotifyRoutine," which apparently impacts all versions of Windows operating systems since Windows 2000. Windows has a built-in API, called PsSetLoadImageNotifyRoutine, that helps programs monitor if any new module has been loaded into memory. Once registered, the program receives notification each time a module is loaded into memory. This notification includes the path to the module on disk. However, Misgav found that due to "caching behaviour, along with the way the file-system driver maintains the file name and a severe coding error," the function doesn't always return the correct path of the loaded modules. What's bad? It seems like Micro

Cybersecurity Tactics FinServ Institutions Can Bank On in 2024

Cybersecurity Tactics FinServ Institutions Can Bank On in 2024
Feb 14, 2024Financial Security / Cyber Threats
The landscape of cybersecurity in financial services is undergoing a rapid transformation. Cybercriminals are exploiting advanced technologies and methodologies, making traditional security measures obsolete. The challenges are compounded for community banks that must safeguard sensitive financial data against the same level of sophisticated threats as larger institutions, but often with more limited resources. The FinServ Threat Landscape Recent trends show an alarming increase in sophisticated cyber-attacks. Cybercriminals now deploy advanced techniques like deep fake technology and AI-powered attacks, making it increasingly difficult for banks to differentiate between legitimate and malicious activities. These developments necessitate a shift towards more sophisticated and adaptive cybersecurity measures. Take these industry statistics, for example. Financial firms report 703 cyberattack attempts per week.1 On average, 270 attacks (entailing unauthorized access of data, appl

New GhostHook Attack Bypasses Windows 10 PatchGuard Protections

New GhostHook Attack Bypasses Windows 10 PatchGuard Protections
Jun 23, 2017
Vulnerabilities discovered in Microsoft PatchGuard kernel protection could allow hackers to plant rootkits on computers running the company's latest and secure operating system, Windows 10. Researchers at CyberArk Labs have developed a new attack technique which could allow hackers to completely bypass PatchGuard, and hook a malicious kernel code (rootkits) at the kernel level. PatchGuard, or (or Kernel Patch Protection) is a software tool that has been designed to forbid the kernel of 64-bit versions of Windows OS from being patched, preventing hackers from running rootkits or executing malicious code at the kernel level. Dubbed GhostHook , the attack is what the CyberArk Labs researchers call the first attack technique that thwarts the defensive technology to bypass PatchGuard, though it requires a hacker to already be present on a compromised system and running code in the kernel. So, basically, this is a post-exploitation attack. "[GhostHook] is neither an

Microsoft Says Russian Hackers Using Unpatched Windows Bug Disclosed by Google

Microsoft Says Russian Hackers Using Unpatched Windows Bug Disclosed by Google
Nov 02, 2016
Google's Threat Analysis Group publically disclosed on Monday a critical zero-day vulnerability in most versions of Windows just 10 days after privately disclosed both zero days to Microsoft and Adobe. While Adobe rushed an emergency patch for its Flash Player software on October 26, Microsoft had yet to release a fix. Microsoft criticized Google's move, saying that the public disclosure of the vulnerability — which is being exploited in the wild — before the company had time to prepare a fix, puts Windows users at "potential risk." The result? Windows Vista through current versions of Windows 10 is still vulnerable , and now everybody knows about the critical vulnerability. Now, Microsoft said that the company would be releasing a patch for the zero-day flaw on 8th November, as part of its regular round of monthly security updates. Russian Hackers are actively exploiting critical Windows kernel bug Microsoft acknowledged the vulnerability in a blog

15-Year-Old JasBug Vulnerability Affects All Versions of Microsoft Windows

15-Year-Old JasBug Vulnerability Affects All Versions of Microsoft Windows
Feb 11, 2015
Microsoft just issued a critical patch to fix a 15-year-old vulnerability that could be exploited by hackers to remotely hijack users' PCs running all supported versions of Windows operating system . The critical vulnerability — named " JASBUG " by the researcher who reported the flaw — is due to a flaw in the fundamental design of Windows that took Microsoft more than 12 months to release a fix. However, the flaw is still unpatched in Windows Server 2003, leaving the version wide open to the hackers for the remaining five months. HACKERS CAN EASILY HIJACK YOUR WINDOWS MACHINE The vulnerability ( CVE-2015-0008 ) could allow an attacker to easily hijack a domain-configured Windows system if it is connected to a malicious network – wirelessly or wired, giving attacker consent to do various tasks including, to go forth and install programs; delete, alter or peruse users' data; or to create new accounts with full user rights. However, Jasbug vulnerability do not affects h

Early 2012 ESET company a mysterious malware, dubbed the Avatar rootkit (Win32/Rootkit.Avatar), advertised in the underground forums by Russian cyber crime . " We present you here previously announced product. In connection with work on other projects, we moved the release date for the public from May to February 2013th 2012go.Now nuclear rootkit AVATAR is available for rental. " Despite the malware was described months ago it was not found and published until now, in March ESET researchers detected two droppers with different C&C servers and having different compilation time stamps as showed in the following pictures: The Avatar rootkit appears very sophisticated, it uses two different infection techniques, the first in the dropper so as to bypass detections by HIPS, and the second one in the rootkit driver to allow the malware to be alive after system reboot, the instance detected works only on x86 systems. The 2 level dropper for Avatar rootkit works in conjunct

Running Desktop Apps on Windows RT, The Hackers Way!
Jan 08, 2013
A hacker claims to have found a method in the code integrity mechanism in Windows RT, that allow one to bypass security mechanism preventing unauthorized software running on ARM-powered Windows RT tablets. Lets see, How to Run traditional desktop apps on Windows RT in a Hackers  Way! A hacker called ' C. L. Rokr ' explain about the Windows RT exploit on his blog , which requires manipulating a part of Windows RT's system memory that governs whether unsigned apps can run. Windows RT is a special version of Microsoft Windows designed for lightweight PCs and tablets that are based on the ARM architecture, including Microsoft's Surface tablet.  Clrokr said Windows RT inherited a flaw from Windows 8 that makes the workaround possible. " Ironically, a vulnerability in the Windows kernel that has existed for some time and got ported to ARM just like the rest of Windows made this possible, ". Specifically, one needs to inject a blob of ARM code into a safe
