Nemesis Bootkit Malware the new stealthy Payment Card.

After I read many articles I got this infos about Nemesis Bootkit Malware:
 - suspected to originate from Russia;
 - infect PCs by loading before Windows starts
 - has ability to modify the legitimate volume boot record;
 - seam to be like another Windows rootkit named Alureon;
 - intercepts several system interrupts to pass boot process;
 - can steal payment data from anyone's not just targeting financial institutions and retailers;
 - this malware hides between partitions and is also almost impossible to remove;

I think about the antivirus and internet security solutions can deal with this type of issues.

Take a look at how fast working the scan disk and how it's working the memory traps, how it's working the booting process or maybe try to see how selinux works.
In my opinion these Antivirus and Internet security solutions are just not effective in design and heuristic detection.
Most of that the prices of this softwars is huge versus non make anything all.

Maybe will see into the future a mega malware wich jump from first boot to any operating system and this because the hardware is more complex and fast.

How to fix Grub2 bootloader flaw.

According to researchers Ismael Ripoll and Hector Marco,who wrote this article:

A vulnerability in Grub2 has been found. Versions from 1.98 (December, 2009) to 2.02 (December, 2015) are affected. The vulnerability can be exploited under certain circumstances, allowing local attackers to bypass any kind of authentication (plain or hashed passwords). And so, the attacker may take control of the computer.

Just hit the backspace key 28 times at the Grub username prompt during power-up.
This will open a Grub rescue shell with the rescue shell allows unauthenticated access to a computer and the ability to load another environment.
The Grub versions 1.98 to 2.02 are affected and suffer integer overflow problem.
The basic of the fault lies within two functions; the grub_password_get() function and the and grub_password_get() script.
To fix it use this patch.

No comment

Wikipedia source: 
No comment is a phrase used as a response to journalistic inquiries which the respondent does not wish to answer. Public figures may decline to comment on issues they are questioned or have nothing to say about the issue at the time. Officials not given authorization by their higher authority to speak to the media similarly may decline to comment. No comment indicates that the speaker does not choose to say anything on the subject, and it is automatically invalidated if the speaker then comments or answers questions. It is not a request for the material to be considered off the record or otherwise kept confidential. If the speaker wishes to talk about the subject, but does not wish to be named as a source, they must obtain the journalist's explicit agreement in advance that the response is not to be used for attribution. 

 The Latest News: 
Just in time for the 24th Birthday of the Linux Kernel, the Linux Foundation has released the first episode in a new web video animation series that shows us what a world without Linux might be like.

Google Shutting Down Google+ Photos !

Google announced in a post on its social network site, it will begin winding down Google+ Photos: on August 1st we’ll start to shut down Google+ Photos -- initially on Android, and soon thereafter on the Web and iOS. How to fix that ... ? So you need to download the new Google Photos today for uninterrupted access to all your photos, videos and albums. To do that use android.apps.photos. With the new app you’ll still be able to backup, edit, and share your photos and videos, with unlimited storage, automatic organization, and more. The biggest difference is that :
  • Google+ users had to actually visit the network on the web to access photos;
  • Google Photos has its own dedicated web interface.
Also your photos and video will still remain available for download through Google Takeout - a program that allows users to download a copy of their data stored within Google products.

The VirtualBox and Fedora 22.

I used the VirtualBox - version 4.3.28.xxxx and Fedora Linux 22.
The main reason was to test how fast it's the  Fedora 22 over VirtualBox.
And the answer was just few minutes.
My hardware come with NVIDIA video card Geforce 740M  , CPU : 2117U -1.80Ghz and 4Gb RAM.
I used Fedora-Workstation-netinst-x86_64-22.iso .
This will take some time when you install because this will use network to download all packages.
You need to set one new  linux os over Virtual Box and make this settings:
Load the Fedora .iso and start it with Show/Playbutton.

After all packages are on your computer then the next step come with unload the .iso file and select the virtual drive. This can be seen under Controler:SATA . Let all settings under Network : NAT. Start it with Show button and you will see it workin well.



I like very much the new Virtual Box and Fedora also, because it's fast (~ 1 min) and I don't need to start another hardware to test my linux stuff.
