Can you name which Operating System is most Secure ? ...Windows, Mac, Linux or any particular Linux Distribution? Yes, we get that! It's not an easy thing to pick. Besides Windows, Even the so-called ultra-secure Linux Distros were found to be vulnerable to various critical flaws in past years. Because, almost all Linux Distros use the same Kernel, and the most number of cyber attacks target the Kernel of an operating system. So, It doesn't matter which Linux distribution you use. The kernel is the core part an operating system, which handles all the main activities and enforces the security mechanisms to the entire operating system. Making an Operating System secure requires that vulnerabilities shall not exist in the Kernel, which is the communicating interface between the hardware and the user.  To overcome the above situation, Security Researchers, Mathematicians and Aviation gurus from Boeing and Rockwell Collins joined a team of dedicated NIC

First announced over five years ago, ex-Google engineer Kent Overstreet is pleasured in announcing the general availability of a new open-source file-system for Linux, called the Bcache File System (or Bcachefs ). Bcachefs is a Linux kernel block layer cache that aims at offering a speedier and more advanced way of storing data on servers. Bcachefs promises to provide the same performance and reliability as the consecrated EXT4 and XFS file systems while having features of the ZFS and Btrfs file systems . Features that Bcachefs Supports Bcachefs supports all the features of a modern file-system, including: Checksumming to ensure data integrity Compression to save space Caching for quick response Copy-on-Write (COW) that offers the ability for a single file to be accessed by multiple parties at once What's coming next for Bcachefs It seems that some of the features in Bcachefs are limited or missing, which includes: Snapshots Erasure codi

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1.

The United States National Security Agency (NSA) has released a network security tool for Government and the private sectors to help secure their networks against cyber attacks. Dubbed Systems Integrity Management Platform (SIMP) , the tool is now publicly available on the popular source code sharing website GitHub . According to an official release from NSA, SIMP makes it easier for government organizations and the private sector to "fortify their networks against cyber threats." SIMP aims at providing a reasonable combination of security compliance and operational flexibility , keeping networked systems compliant with security standards and requirements. It is considered to be a critical part of a layered, "defence-in-depth" approach to information security. " By releasing SIMP, the agency seeks to reduce duplication of effort and promote greater collaboration within the community: The wheel would not have to be reinvented for every organiza

Apple's operating system is considered to be the most secure operating system whether it's Mac OS X for desktop computers or iOS for iPhones. But believe it or not, they are the most vulnerable operating system of year 2014. MOST VULNERABLE OPERATING SYSTEM  Windows, which is often referred to as the most vulnerable operating system in the world and also an easy pie for hackers, is not even listed on the top three vulnerable OS. According to an analysis by the network and security solutions provider GFI, the top three most vulnerable operating system are: Apple's Mac OS X Apple iOS Linux kernel GFI analysis is based on the data from the US National Vulnerability Database (NVD ), which shows that in 2014, the top three most vulnerable operating systems took owner by the following number of vulnerabilities reported in their software: Mac OS X - Total 147 vulnerabilities were reported, 64 of which were rated as high-severity Apple's iOS - Total 127 vulnerabilities were reported,

A critical vulnerability has been fixed in Samba — Open Source standard Windows interoperability suite of programs for Linux and Unix, that could have allowed hackers to remotely execute an arbitrary code in the Samba daemon ( smbd ). Samba is an open source implementation of the SMB/CIFS network file sharing protocol that works on the majority of operating systems available today, which allows a non-Windows server to communicate with the same networking protocol as the Windows products. Samba is supported by many operating systems including Windows 95/98/NT, OS/2, and Linux. smbd is the server daemon of Samba which provides file sharing and printing services to clients using the SMB/CIFS protocol. Samba is also sometimes installed as a component of *BSD and OS X systems. The vulnerability, designated as CVE-2015-0240 , actually resides in this smbd file server daemon. The bug can be exploited by hackers to potentially execute code remotely with root privileges, the

Werner Koch , the man who authored the free email encryption software , is running out of funding to continue the development of his crucial open-source GNU Privacy Guard (GnuPG) encryption tools.The code works on plenty of operating systems from Linux and FreeBSD to Windows and OS X. The popular Gnu Privacy Guard (GnuPG or GPG) email encryption software is the same used by the former United States National Security Agency (NSA) contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement authorities. GPG uses the OpenPGP standard to safeguard the communications of millions of people, including journalists, dissidents and security-minded people, around the world from eavesdroppers and other miscreants. GPG EMAIL ENCRYPTION RELIES ON THIS GUY ONLY Werner Koch has been maintaining and improving the code of his own secure email software since its initial development in 1997, and since then he has worked at very low wages, but is now

A highly critical vulnerability has been unearthed in the GNU C Library (glibc) , a widely used component of most Linux distributions, that could allow attackers to execute malicious code on servers and remotely gain control of Linux machines. The vulnerability, dubbed " GHOST " and assigned CVE-2015-0235 , was discovered and disclosed by the security researchers from Redwood Shores, California-based security firm Qualys on Tuesday. CRITICAL AS HEARTBLEED AND SHELLSHOCK GHOST is considered to be critical because hackers could exploit it to silently gain complete control of a targeted Linux system without having any prior knowledge of system credentials (i.e. administrative passwords). Also Read:  Top Best Password Managers . The flaw represents an immense Internet threat, in some ways similar to the Heartbleed ,   Shellshock   and Poodle   bugs that came to light last year. WHY GHOST ? The vulnerability in the GNU C Library (glibc) is dubbed GHOST b

From last week, Google began paving the way to run Android apps on Chrome Operating System through the project named " App Runtime for Chrome ", but the release came with a lot of limitations – it only supported certain Android apps and on Chrome OS only. At the launch, initially only 4 Android apps – Vine, Evernote, Duolingo and Sight Words – were added to the Chrome Web Store. That was pretty exciting, but it merely whet the appetite of users hungry for more functionality. So, what if you could run more than just 4 Android apps on Chrome OS? And Also could run them on other operating systems as well? A developer by the name of " Vlad Filippov " began working on it to stripped away the limits Google has imposed. He successfully figured out a way to bring more Android apps to Chrome , instead of just the four that are officially supported by Google. The bigger success was that when Filippov got Android apps to work on any desktop Operating System tha

Good news for Firefox lovers!

We all are aware of the National Security Agency's (NSA) mass surveillance program to track non-Americans. Thanks to former NSA contractor Edward Snowden, who provided confidential documents about the widely spread surveillance programs conducted by the government intelligence agency such as NSA and GCHQ. A recent story about NSA surveillance broke when a German public broadcaster ARD published that the Agency is using its surveillance program XKeyScore to target users who use encryption and traffic anonymizing software, including Tor Network for anonymous Web browsing and Linux-based Tails operating system in an effort to keep tracks of people outside the US. XKeyScore is a powerful NSA surveillance program that collects and sorts intercepted data, which came to limelight in documents leaked by former NSA contractor Edward Snowden last summer, but the greater detail in an investigation conducted by American security expert and Tor Project member Jacob Appelbaum , Aaron Gibsom, and

When it comes to Digital Forensics, Penetration and Security testing, we mostly relies on Kali Linux distribution (also known as Backtrack), which is designed for security professionals and packed with more than 300 security testing tools. But Today, Mailing List sub-domain of Kali Linux get hacked and defaced by Libyan hacking group known as ' The GreaT TeAm (TGT) '. A mailing list is simply a list of email addresses to which the same information is being sent. A discussion list is used to allow a group of people to discuss topics amongst themselves, with everyone able to send mail to the list and have it distributed to everyone in the group. Mailing lists have become a popular way for Internet users to keep up with topics they're interested in. At the time of writing, The Homepage of Kali Linux mailing list domain was displaying two lists, i.e. Kali with description "Hacked By The GreaT TeAm -TGT" Kali-Dev with description "Libyan Hackers" S

As we have reported you earlier that Microsoft is pulling out their Windows XP support after April 8 2014. Since a vast majority of bank ATMs around the world currently runs on Windows XP, but if they'll continue sticking to it after the deadline, then they'll be exposed to all kinds of security threats, as Microsoft will no longer provide the security patches thereafter. Many countries' Banks have got a way out, many banks have arranged or are in the process of arranging extended support for Windows XP for which they are ready to pay Microsoft millions of dollars, but may be not in the case of India. Yes, India will never feed Microsoft for providing extra support to the older version; rather they could switch over to the Linux operating system. India has around 115,000 ATMs across the country at present and the counts will go up in coming days, but the end of life for XP will not affect banks and functioning of ATMs as the financial institutions across the country are we

Could a perfectly innocent looking device like router, TV set-top box or security cameras can mine Bitcoins? YES! Hackers will not going to spare the Smart Internet-enabled devices. A Linux worm named Linux . Darlloz , earlier used to target Internet of Things (IoT) devices, i.e. Home Routers, Set-top boxes, Security Cameras, printers and Industrial control systems; now have been upgraded to mine Crypto Currencies like Bitcoin. Security Researcher at Antivirus firm Symantec spotted the Darlloz Linux worm back in November and they have spotted the latest variant of the worm in mid-January this year. Linux . Darlloz worm exploits a PHP vulnerability ( CVE-2012-1823 ) to propagate and is capable to infect devices those run Linux on Intel's x86 chip architecture and other embedded device architectures such as PPC, MIPS and MIPSEL. The latest variant of Linux . Darlloz equipped with an open source crypto currency mining tool called ' cpuminer ', could be use

These days botnets are all over the news. In simple terms, a botnet is a group of computers networked together, running a piece of malicious software that allows them to be controlled by a remote attacker. A major target for most of the malware is still Windows, but the growing market of Mac OS X, Linux and Smartphones, is also giving a solid reason to cyber criminals to focus. Recently, Kaspersky Lab has detected another cross-platform Java-Bot , capable of infecting computers running Windows, Mac OS X, and Linux that has Java Runtime Environment installed. Last year, Zoltan Balazs - CTO at MRG Effitas submitted the samples of malicious Java application for analysis to Kaspersky Lab and they identified it as HEUR : Backdoor.Java.Agent.a . According to researchers, to compromise computers, Java-Bot is exploiting a previously known critical Java vulnerability CVE-2013-2465 that was patched in last June. The vulnerability persists in Java 7 u21 and earlier vers

Last year in the month of December the Security-focused Unix-like distribution ' OpenBSD ' Foundation announced that it was facing shut down due to lack of funds to pay their electricity bills and dedicated Internet line costs. Theo de Raadt , the founder of the OpenBSD project, and Bob Beck (Developer) announced : " In light of shrinking funding, we do need to look for a source to cover project expenses. If need be the OpenBSD Foundation can be involved in receiving donations to cover project electrical costs. But the fact is right now, OpenBSD will shut down if we do not have the funding to keep the lights on. " Just after a month, a Bitcoin billionaire from Romania has stepped in and sorted OpenBSD out! Mircea Popescu , the creator of the MPEx Bitcoin stock exchange has offered $20,000 donations to the OpenBSD Foundation and saved the existence of OpenBSD development from being stopped. Like each open source project, OpenBSD production servers we

A few days back the developers of one of the most advance open source operating system for penetration testing called ' KALI Linux ' announced that they were planning to include " emergency self-destruction of LUKS ". They patched a utility called cryptsetup,  which introduces a self destruction feature that will allow the Kali user to encrypt the full hard disk to make the data inaccessible in an emergency case by entering a secret password at boot time. Offensive Security has finally announced today the release of the latest version i.e. Kali Linux 1.0.6 with Kernel version 3.12, and also added the Self Destruct feature along with many new penetration testing and hacking tools. The new release also includes an ARM image script, that allow the user to build Kali Linux images for various ARM devices. Some more scripts are also added that enables the user to build their own custom Amazon AMI and Google Compute cloud images. If you already have a Kali Linux insta

X.Org Foundation develops the X-Window System, the standard window system for open source operating systems and devices. Most of the graphical user interfaces for Unix and Linux systems rely on it. At the 30th Chaos Communication Congress (CCC) in Germany, Ilja van Sprundel , a security researcher gave the presentation titled  " X11 Server security with being 'worse than it looks.'". He found more than 120 bugs in a few months. In the presentation, he has presented a 23 year old Stack overflow vulnerability in X11 System that could lead to privilege escalation to root and affects all versions of the X Server back to X11R5. Later today, X.Org Foundation released a security Advisory , states " A BDF font file containing a longer than expected string could overflow the buffer on the stack. Testing in X servers built with Stack Protector resulted in an immediate crash when reading a user-provided specially crafted font. " The flaw resides in a file at " libXfo
