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 ...

It's been over a month since the WannaCry ransomware caused chaos worldwide and people have started counting its name as 'the things of past,' but… ...WannaCry is not DEAD! The self-spreading ransomware is still alive and is working absolutely fine. The latest victims of WannaCry are Honda Motor Company and 55 speed and traffic light cameras in Australia. The WannaCry ransomware shuts down hospitals, telecom providers, and many businesses worldwide, infecting over 300,000 Windows systems running SMBv1 in more than 150 countries within just 72 hours on 12th of May. The worm was leveraging an NSA's Windows SMB exploit, dubbed EternalBlue , leaked by the infamous hacking group Shadow Brokers in its April data dump, along with other Windows exploits. Honda Stops Production After WannaCry Hits its Computer Honda Motor Company released a statement this week, saying the company was forced to halt its production for more than 24 hours at in one of its Japan...

WikiLeaks has published a new batch of the ongoing Vault 7 leak , this time detailing a tool suite – which is being used by the CIA for Microsoft Windows that targets "closed networks by air gap jumping using thumb drives," mainly implemented in enterprises and critical infrastructures. Air-gapped computers that are isolated from the Internet or other external networks are believed to be the most secure computers on the planet have become a regular target in recent years. Dubbed Brutal Kangaroo (v1.2.1), the tool suit was allegedly designed by the Central Intelligence Agency (CIA) in year 2012 to infiltrate a closed network or air-gapped computer within an organization or enterprise without requiring any direct access. The previous version of Brutal Kangaroo was named as EZCheese , which was exploiting a vulnerability that was zero-day until March 2015, though the newer version was using " unknown link file vulnerability (Lachesis/RiverJack) related to the lib...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

A security researcher has found four vulnerabilities, including a critical remote code execution bug, in OpenVPN, those were not even caught in the two big security audits of the open source VPN software this year. OpenVPN is one of the most popular and widely used open source VPN software solutions mostly used for various connectivity needs, but it is especially popular for anonymous and private access to the Internet. This year, two independent security audits of OpenVPN were carried out to look for flaws, backdoors, and other defects in the open source software – one conducted by a team led by Johns Hopkins University crypto-boffin Dr. Matthew D. Green. The audits resulted in a patch of a few vulnerabilities in the widely used open source software, giving OpenVPN a clean chit. Researcher Used Fuzzer to find Bugs in OpenVPN Researcher Guido Vranken of Netherlands exclusively used a fuzzer and recently discovered four security holes in OpenVPN that escaped both the secur...

'Do I really need to give this website so much about me?' That's exactly what I usually think after filling but before submitting a web form online asking for my personal details to continue. I am sure most of you would either close the whole tab or would edit already typed details (or filled up by browser's auto-fill feature) before clicking 'Submit' — Isn't it? But closing the tab or editing your information hardly makes any difference because as soon as you have typed or auto-filled anything into the online form, the website captures it automatically in the background using JavaScript, even if you haven't clicked the Submit button. During an investigation, Gizmodo has discovered that code from NaviStone used by hundreds of websites, invisibly grabs each piece of information as you fill it out in a web form before you could hit 'Send' or 'Submit.' NaviStone is an Ohio-based startup that advertises itself as a service to u...

The National Security Agency (NSA) — the United States intelligence agency which is known for its secrecy and working in the dark — has finally joined GitHub and launched an official GitHub page. The NSA employs genius-level coders and brightest mathematicians, who continually work to break codes, gather intelligence on everyone, and develop hacking tools like EternalBlu e that was leaked by the Shadow Brokers in April and abused by the WannaCry ransomware last month to wreak havoc worldwide. The intelligence agency mostly works in secret, but after Edward Snowden leaks in 2013, the NSA has started (slowly) opening itself to the world. It joined Twitter in the same year after Snowden leaks and now opened a Github account. GitHub is an online service designed for sharing code amongst programmers and open source community, and so far, the NSA is sharing 32 different projects as part of the NSA Technology Transfer Program ( TTP ), while some of these are 'coming soon.' ...

It seems Microsoft is planning to build its EMET anti-exploit tool into the kernel of Windows 10 Creator Update (also known as RedStone 3), which is expected to release in September/October 2017. So you may not have to separately download and install EMET in the upcoming version of the Windows 10. If true, this would be the second big change Microsoft is making in its Windows 10 Fall update after planning to remove SMBv1 to enhance its users security. EMET or Enhanced Mitigation Experience Toolkit, currently optional, is a free anti-exploit toolkit for Microsoft's Windows operating systems designed to boost the security of your computer against complex threats such as zero-day vulnerabilities. " EMET helps protect your computer systems even before new and undiscovered threats are formally addressed by security updates and antimalware software ," Microsoft site reads. Basically EMET detects and prevents buffer overflows and memory corruption vulnerabilities,...

The Server Message Block version 1 (SMBv1) — a 30-year-old file sharing protocol which came to light last month after the devastating WannaCry outbreak — will be removed from the upcoming Windows 10 (1709) Redstone 3 Update. The SMBv1 is one of the internet's most ancient networking protocols that allows the operating systems and applications to read and write data to a system and a system to request services from a server. The WannaCry ransomware , which wreaked havoc last month, was also leveraging an NSA's Windows SMB exploit, dubbed EternalBlue , leaked by the Shadow Brokers in its April data dump. The WannaCry ransomware menace shut down hospitals , telecommunication providers, and many businesses worldwide, infecting hundreds of thousands of unpatched Windows servers running SMBv1 in more than 150 countries within just 72 hours on 12th of May. Although Microsoft patched the vulnerability in SMBv1 in March in MS17-010 , the company meanwhile strongly advised us...

Update: Find working Exploits and Proof-of-Concepts at the bottom of this article. Security researchers have discovered more than a decade-old vulnerability in several Unix-based operating systems — including Linux, OpenBSD, NetBSD, FreeBSD and Solaris — which can be exploited by attackers to escalate their privileges to root, potentially leading to a full system takeover. Dubbed Stack Clash , the vulnerability ( CVE-2017-1000364 ) has been discovered in the way memory was being allocated on the stack for user space binaries. Exploiting Stack Clash Bug to Gain Root Access The explanation is simple: Each program uses a special memory region called the stack, which is used to store short-term data. It expands and contracts automatically during the execution of any program, depending upon the needs of that program. According to researchers at Qualys, who discovered and reported this bug, a malicious program can attempt to use more memory space than available on the stack,...
