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.

Fedora 23 - error with win qemu and virtualbox.

First I try to use WinQemu from here : qemu-w64-setup-20151115.exe 2015-11-15 11:15 22M QEMU Installer for Windows (64 bit).
I use this commands for qemu:
C:\qemu>qemu-img create -f qcow2 fedora23_disk.img 8G 
C:\qemu>qemu-system-x86_64w.exe -hda fedora23_disk.img -cdrom Fedora-Live-Workstation-x86_64-23-10.iso -boot d
The output error come with this image:
 
I try also with VirtualBox - using same size 8Gb of disk image but seam come with errors.
 I use Intel CPU 2117U @ 1.80Ghz / 4Gb Ram and Nvidia Geforce GT 740M video card, but seam this not help me.

GIF file animated with open-source software.

I tested the Blender 3D version 2.76 with Inkscape and Synfig to make this GIF animated.
This is the result :

I used the default cube from Blender 3D to make a SVG image. 

Also I working with Synfig software to create this GIF. 

I will make one good tutorial about this GIF. 

I hope this will help you to find new ways to deal with the open-source software.

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 a 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 the network to download all packages.
You need to set one new  Linux os over Virtual Box and make this setting:
Load the Fedora .iso and start it with Show/Play button.

After that, if all packages are on your computer then the next step comes with unloading 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 working 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.

Fix Bash shell vulnerability under Linux OS .

If some Bash code outside of the curly brace then it will then be executed by the linux system.

env x='() { :;}; echo vulnerable' bash -c " bash test "

If your system is vulnerable, it will then output:

bash test 

How Do You Fix It ? Just open up a terminal, and type:

sudo apt-get update
sudo apt-get upgrade

or under Fedora with :

sudo yum update
