North Korea has its own homegrown computer operating system that looks remarkably just like Apple's OS X, which not only prevents potential foreign hacking attempts but also provides extensive surveillance capabilities. Two German researchers have just conducted an in-depth analysis of the secretive state's operating system and found that the OS does more than what is known about it. Dubbed Red Star OS , the operating system based on a Linux 2009 version called Fedora 11 limits its users to a government-approved view of the world and has the tendency to ' watermark ' files on USB sticks to track user's shuttling contraband material. Red Star OS Tracks User's Every Move In short, whenever a user inserts a USB storage device containing photos, videos or other documents, into a computer running Red Star, the OS takes the current hard disk's serial number, encrypts that number, and writes that encrypted serial into the file, marking it. The p...

Google is planning to merge its Chrome OS with Android operating system and roll out a single operating system by 2017. New Android OS Optimized for Laptops: Yes, a Single Operating system for Mobile devices, desktops, laptops and notebooks, just what Microsoft is offering to its users with  Windows 10 .

A security researcher has discovered a critical vulnerability in the latest version of Apple's OS X Yosemite  that could allow anyone to obtain unrestricted root user privileges with the help of code that fits in a tweet. The privilege-escalation vulnerability initially reported on Tuesday by German researcher Stefan Esser , could be exploited by to circumvent security protections and gain full control of Mac computers. The most worrying part is that this critical vulnerability is yet to be fixed by Apple in the latest release of its operating system. This could make it easier for hackers to surreptitiously infect Macs with rootkits and other types of persistent malware. Thanks to an environment variable DYLD_PRINT_TO_FILE Apple added to the code of OS X 10.10 Yosemite. Apple Mac OS X Vulnerability Gives Full Control of your Mac This environment variable specifies where in the file system an operating system component called the OS X dynamic linker dyld ...

Hackers have their hands on something of your concern. A severe zero-day vulnerability in the latest, fully patched version of Apple's Mac OS X is reportedly being exploited in the wild by the hackers. The vulnerability could allow attackers to install malware and adware onto a target Mac, running OS X 10.10 (Yosemite) operating system, without requiring victims to enter system passwords , a new report says. The zero-day bug came over a week after security researcher Stefan Esser discovered a privilege escalation zero-day vulnerability in the latest version of Apple's OS X Yosemite that caused due to environment variable DYLD_PRINT_TO_FILE and dynamic linker dyld , new error-logging features added to the operating system. The developers failed to implement standard safeguards that are needed while adding support for new environment variables to the OS X dynamic linker dyld, allowing hackers to create or modify files with root privileges that can fit anywhere i...

In January 2012, Microsoft confirmed to PC manufacturers that they must enable Secure Boot by default on PCs to be "Certified for Windows 8". The purpose of Secure Boot is to put an end to computer viruses that sneak between the hardware and the operating system. These viruses, also known as bootkits, work by getting themselves loaded before the operating system, then they make changes to the operating system while it lies defenseless on disk, and then they load the now defenseless operating system and have their way with it. Secure Boot counters the bootkit by ensuring the hardware verifies the identity and authenticity of the software that sits between the hardware and the operating system - the bootloader, and also the software embedded in hardware devices like network and graphics adapters. Secure Boot sounds like a smart solution to the bootkit problem doesn't it? Who wouldn't want a secure boot? Proponents of alternative operating syst...

A Swedish Security researcher has discovered a critical vulnerability in Apple's OS X Yosemite that gives hackers the ability to escalate administrative privileges on a compromised machine, and allows them to gain the highest level of access on a machine, known as root access. The vulnerability, dubbed as " Rootpipe ", was uncovered by Swedish white-hat hacker Emil Kvarnhammar , who is holding on the full details about the privilege escalation bug until January 2015, as Apple needs some time to prepare a security patch. " Details on the #rootpipe exploit will be presented, but not now. Let's just give Apple some time to roll out a patch to affected users, " Emil Kvarnhammar, IT specialist and hacker security company Truesec, tweeted from his twitter account. By exploiting the vulnerability in the Mac OS X Yosemite , an attacker could bypass the usual safeguard mechanisms which are supposed to stop anyone who tries to root the operating system through a tempora...

Sad but True! Your Apple's Mac computer is vulnerable to a serious privilege escalation flaw, dubbed "RootPipe," even if you are running the latest version of Mac OS X. What's RootPipe? Back in October 2014, a Swedish White Hat hacker Emil Kvarnhammar claimed to have discovered a critical privilege escalation vulnerability, he dubbed the backdoor as " RootPipe ," in some versions of Mac OS X including the then newest version 10.10 Yosemite. The vulnerability ( CVE-2015-1130 ) could allow an attacker to take full control of your desktop Mac computer or MacBook laptop, even without any authentication. Keeping in mind the devastating effect of the RootPipe vulnerability, the researcher privately reported the flaw to Apple and did not disclose the details of the flaw publicly until the company released a patch to fix it. Apple did release an update but failed to patch RootPipe: Earlier this month, Apple released the latest version of Mac OS...

Till now we have seen a series of different malware targeting Windows operating system and not Mac, thanks to Apple in way it safeguard its devices' security. But with time, cyber criminals and malware authors have found ways to exploit Mac as well. GROUP BEHIND THE MAC VERSION OF BACKDOOR Researchers have unmasked a group of cyber criminals that has recently started using a new variant of XSLCmd backdoor program to target Mac OS X systems. This Mac version of backdoor shares a significant portion of its code with the Windows version of the same backdoor that has been around since at least 2009. According to FireEye researchers, the group, dubbed as GREF , is already infamous for its past cyber espionage attacks against the US Defense Industrial Base (DIB), companies from the electronics and engineering sectors worldwide, foundations and other NGO's as well. " We track this threat group as "GREF" due to their propensity to use a variety of Google references in th...

Google's long-rumored Android-Chrome hybrid operating system is expected to debut at the company's upcoming hardware event on October 4. The company has been working to merge the two OSes for roughly 3 years with a release planned for 2017, but an "early version" to show things off to the world in 2016. Android + Chrome = Andromeda The hybrid OS, currently nicknamed 'Andromeda,' could be come on a new Pixel laptop as well as Huawei Nexus tablet from Google by Q3 2017, if not sooner, according to new leaks from 9to5Google and Android Police . Andro id + Ch rome = Andromeda The laptop, officially codenamed " Bison " and nicknamed "Pixel 3," is a reference to the "Chromebook Pixel," but since this edition is not running Chrome operating system, one can not call it a "Chromebook" anymore. Andromeda is separate from the company's Fuchsia OS , which is focused on Internet-of-Thing (IoT) devices. Moreove...

Pwnium is the annual Hacking competition where Google invites coders from around the world to find security holes in Google Chrome. Google has announced its 4th Pwnium Hacking Contest hosted at the Canadian Security conference in March, offering more than $2.7 million in potential rewards for hacking Chrome OS-running ARM and Intel Chromebook. This year the security researchers have a choice in between an ARM-based Chromebook, the HP Chromebook 11 (WiFi) and the Acer C720 Chromebook (2GB WiFi) based on Intel's Haswell microarchitecture . The attack must be demonstrated against one of these devices running " then-current " stable version of Chrome OS. " Security is a core tenet of Chromium, which is why we hold regular competitions to learn from security researchers. Contests like Pwnium help us make Chromium even more secure ," Jorge Lucángeli Obes, Google Security Engineer said. Amongst the payouts are $110,000 for the browser or s...

Cyber-attacks keep increasing and evolving but, regardless of the degree of complexity used by hackers to gain access, get a foothold, cloak their malware, execute their payload or exfiltrate data, their attack will begin with reconnaissance. They will do their utmost to uncover exposed assets and probe their target's attack surface for gaps that can be used as entry points. So, the first line of defense is to limit the potentially useful information available to a potential attacker as much as possible. As always, the tug of war between operational necessity and security concerns needs to be taken into account, which requires a better understanding of the type of information typically leveraged. What information are hackers looking for during recon? When running recon on an organization, hackers – whether white or black hats - are "casing a joint." To plan their attack, they will try and uncover as much information as possible about: Your infrastructure The types ...

Does downloading Windows updates from Microsoft's servers and waiting too long really annoy you? It might not be with the arrival of Windows 10 . Microsoft seems to make a major change in Windows 10 to the way it delivers updates for the software. The leaked version of Windows 10 build 10036 (the current version is build 9926) allows you to grab OS updates from Microsoft as well as other computers, whether they're on your local network or on the Internet. Yeah, it's a Peer-to-Peer (P2P) technology Microsoft is going to use in order to deliver both app and operating system updates. Peer-to-Peer , or P2P Technology is usually associated with file sharing services like BitTorrent to download illicit copies of movies and albums, and of course, those endless Linux ISOs you've been downloading. However, Redmond is embracing the technology as an efficient means to deliver software updates to its users around the globe. Peer-to-Peer downloads will be o...

Do you think, because you're using an Apple Mac , your data is safe from hackers ? Well, it is not true, there are dozens of security weaknesses and today Researchers have made it easier to exploit Apple Mac OS X, that allows penetration testers and hackers to gain root access. The flaw remained unmatched by Apple for the last five months, dubbed CVE-2013-1775 , the flaw allowed attackers to bypass normal password authentication procedures by resetting the computer clock to January 1, 1970. The reason that specific date is required is because it represents the beginning of time to the operating system and some applications that run on it. When the SUDO command is used in combination with a clock reset, the computer can be tracked into providing root access without a password. Metasploit authors have come up with a brand new module that makes the bug even easier to exploit , renewing interest in the problem. The module gains a session with root permissions as long a...

A group of Indian Hackers has designed Artificial Intelligence Assistant Operating System called ' J.A.R.V.I.S ' , who recognizes them, answer questions, tweet for them and Collect information, scan targets for them. Chiragh Dewan, a 18 year old student who is currently pursuing his BCA has taken the initiative to be the first Indian to complete this project  J.A.R.V.I.S , which is inspired by Iron Man's (movie) artificial intelligence assistant Jarvis.

Like if a doctor is using the OS, it will adapt itself so as it is capable of helping him out in his field like searching for new techniques, medicines, help in their research, etc. Add for architects, other professions.  As for users i...

Android -  a widely used Smartphone platform offered by Google is once again suspected to affect its users with malicious software that puts their android devices at risk. This time the vulnerabilities occur in the way Android handle the updates to add new flavors to your device. Researchers from Indiana University and Microsoft have discovered [ Paper PDF ] a new set of Android vulnerabilities that is capable to carry out privilege escalation attacks because of the weakness in its Package Management Service (PMS) that puts more than one billion Android devices at risk. The researchers dubbed the new set of security-critical vulnerabilities as Pileup flaws which is a short for privilege escalation through updating, that waylays inside the Android PMS and intensifies the permissions offered to malicious apps whenever an android update occurs, without informing users. The research was carried out by Indiana University Bloomington researchers, Luyi Xing, Xiaorui Pan...
