You might want to rethink about keeping your important files in a Linux based computer because Linux has been found being exposed badly to even pettiest hacking attempts. According to a report, about a research by security experts, in PC world, hitting the backspace key 28 times can bypass password protected lock screen in Linux.
It is worth repeating that any layman can now access highly complex Linux servers without even entering the password. This vulnerability of Linux was discovered by a researchers’ team from Cybersecurity Group. According to them, pressing backspace 28 times makes use of Grub2 bootloader, instantly authorizing user to log in.
This process is basically caused by initiation of Grub rescue shell. This initiation prompts the user to bypass log on screen without typing the password in. GRUB’s main task is to allow the creation of multiple usernames on a computer.
With this news about simple hacks, companies with entire networks being set up on Linux based systems should have something big to worry about. All an employee will need to do is to hit backspace 28 times and he/she will get complete and unrestricted access to a hard drive which was supposed to be secured.
There are very alarming security concerns with this weakness of Linux because it can lead to the computer’s security badly exposed to a very small hack. Any cybercriminal with access to sensitive information can do serious damage to an organization’s integrity and even the financial assets. Moreover, this vulnerability has also increased the chances of manual malwares attacks.
This security leak, which is also known as CVE-2015-8370, is present in all Grub2 versions from 1.98 to 2.02. Since many of the top organizations around the globe have their servers based on Linux based platforms, this issue is being seen as a major blow to the overall cyber security. However, different Linux based operating systems namely Debian, Ubuntu, red hat and several others have released updates that fix this issue. Therefore, it is highly recommended for the Linux users to allow installation of updates that target Grub2 fix.
According to the resources and intelligent intuitions by the analysts, Google is more likely to release its Penguin 4.0 update any time soon. While this news can bring happiness for the SEO people who like to stick with the legitimate SEO practices, it is also like a time bomb for the SEO people who like to get quick traffic through black-hat techniques.
We all know that every Penguin update comes with an aim to support high quality link-building and to combat the spam tactics. For instance, last Google Penguin update was released in 2014 and it immediately cased huge disturbance in the digital world. Sites that didn’t abide legitimate SEO rules lost their ranks in no time and were lost from SERPs. Some of the websites even received notifications for manual actions.
This trend of countering spam and removing websites, which followed bad SEO practices, was started a few years back. Due to that, the way search results are shown was changed to great extent. It brought a lot of positives in perspectives of quality and credibility. This was due to the fact that good SEO practices were appreciated and black-hat SEO was disparaged in the Penguin Algorithms.
Penguin 4.0 update is a great enhancement of Google’s spam combating abilities. This update is being analytically assumed as real time update of Google’s algorithms. Real time update means that Penguin’s algorithm will consistently keep on updating, minimizing the remaining chances for spammers to go ahead with their link bombardments. This update is being welcomed by the online community because there is still a major spamming activity going on the web and 4.0 update is expected to show the necessary force to stop this activity. Here, it is worth mentioning that Google claims with every update that it is going to stop bad SEO practices but facts remain otherwise. Nevertheless, this update will make the chances of success for black-hat techniques pretty thin.
Hopefully the new update will help Google to track down spam link profiles and block them once and for all. This is not only bad for the bad practitioners but it will automatically rank up the websites that follow good quality SEO strategies.
