Linux Operating Systems: New Root Virus Attacks!

Is Linux Operating Systems Virus Resistant? Okay the system is highly resourceful. Yes it is known for supporting multi-users connections; all at once. But Don't You think calling it immune to malware, was taking it a little too far?

Linux OS Attracted Badware Authors

Isn't it Possible that Operating Systems like: UNIX, Linux and Mac were NOT as popular as Windows; at the time this assumption was formed.

Linux Had Small Market Shares?

Look! Part of the Popularity comes from its Multi-User and Multi-Tasking functionalities. Another thing worth noting is our needs for a one stop solution. Where an administrator can manage several desktops; which is good for business purposes.
(One Of The Best Internet Security Measure; is learning about the characteristics of several threats:)

That Doesn't Make Unix Or Linux Totally resistant:

The Operating System are comes in several versions. Examples of such are: Linux, HP-UX, Solaris, AIX, XENIX and SINIX.
Being a multi-user OS: it has the astounding ability to handle many users simultaneously. This makes it highly desirable, especially in this time where the internet is dominant.

Linux vs Windows Based Macro Viruses

 In this section we will look at a few useful functions that limits malware. But before you Jump the Gun. Let's look at a few basic functions of a Linux:

  1. The Operating System has the ability to connect multiple users, and easily allow them to perform multi-tasking.
  2. Each user is given authorization to the system. By the means of a user account is created.
  3. Every user has a personal space or home directory.This personalizes the access provided.
  4. The respective user alone can access his/her shell. Which gives a sense of privacy and ownership.
  5. Alternatively the system administrator can access the users account, because he/she may know the password and have authorization on certain circumstances to access it.
Examples Such as; trouble shooting, investigation if it's a business desktop, or fraud cases.
Then you get the people that knows your password. Which is not advisable, even if it's a colleague or spouse. Unless they hacked your system!
What Happens Inside Your Linux System? The groups identity or group ID (GID), helps the system: To confirm the user's identity, or user ID (UID).

Linux Vulnerability vs Malware Infections Root Access:

Firstly, Badware needs root access to infect a Linux. This depends on the user's rights and restrictions. Then the malicious code can be passed on to other users on the network.

Generally There Are Two user account types:

  • The basic (normal) users with restricted privileges or rights.
  • The system administrator: Has many privileges for obvious reasons. Their authoritative rights are referred to as the "root access."

Boot Virus vs Macro Virus:

Why am I Giving You A Brief History Lesson:This will help you to better understand the DISTRUCTIVE Power Of the Macro Virus.
1st: The boot virus was a Traditional File Virus. It was a program based threats, which was shared through program files.
The boot threat infected the boot sector of floppy. The threat needed program files be sent.
This traditional virus are extinct. During of 1995 Windows 95 was introduced, which resisted the threat.

Compare The Two: Boot Virus vs The Latest Macro viruses:

After 1995 just when internet security company thought; their work is done. The macro viruses Emerged. Windows 95 was as vulnerable: As all the executable documents are; till this day.
Macro viruses are written in macro language. The threat is still relevant, and infects documents such as Word, Excel, and any script written with executable codes.
Examples of Such Documents: The macro viruses works on executable codes like MS Office Suite. It thrives on files like MS Word and MS Excel.
However, it's not only limited to them, they thrive on most online files, shareable pdf's, and pretty much any executable script.
The Executable Code Activates the Virus:
  1. The virus to intuitively adds its macros to the targeted file, using the files own resources against itself.
  2. The macros works like a well-oiled engine on automation. They get prompted as soon as you open the infected document.
As soon as the document is copied, or attached to other files. The same automation process repeats.

In Comparison MACRO Viruses Are More Darker And Deadlier that the BOOT:

Although the Boot is done away with. Measuring the Macro viruses by its standards. Macro are by far more sophisticated and powerful. They grow like a living organism, and spreads with ultra fast speeds.

Another Distinctive Punch The Macro Virus Packs:

  1. It Goes Straight for the Jugular vein. Well, in the case of your Computer or Network. It targets files, rather than programs.
  2. So imagine how many files we share daily, download, or access daily. This demonstrates how rapidly this virus is transmitted.

The distinctive characteristics above makes the macro virus: Dominant, intrusive, efficient and hidden in our daily activities online.
Smart Positioned Threat, It's Cleverly Merged Into Your Online Activities: A Computer is a programmable electronic device, that performs mathematical calculations, and logical operations, especially one that can process, store and retrieve large amounts of data very quickly.
Alternatively, we use this tool for personal, home, or business purposes. It is practically used for manipulating text, graphics, accessing the Internet, playing games or media.
The Macro virus is Accurately and firmly positioned, in the most useful features. You simply you can't use your computer. Without activating or transferring this threat to other users.

How Do You Prevent One Linux User From Transferring The Virus To Others?

By using the knowledge we've gathered; from the history of Viruses. It teaches us that viruses.
Particularly ones that attacks files/documents, are more lethal and efficient. If compare them to the old viruses that targeted programs.

The Best And Most Common Mediums that Viruses Are Transferred.

  • Email has become one of the Worlds preferred: Professional communication medium. Macros are easily attached knowingly, or unknowingly to other users.
  • USB flash drives, file transferring, external drives, bluetooth and SMARTPHONES.
  • The internet medium, downloadable content, files, and attachments.

Program Virus Language Versus Macro Language:
The Boot was Program based and written in technical codes, complex computer languages. It could NOT be read by ordinary folks/users.
Ultimately, it could only be read, or translated by ADVANCED tools.

The latest Macro Viruses

Are different, readable and even better Yet! It's written simple language, clear to understand and easy to translate by ordinary folks.
This Makes It Scarier! Do You Know Why?
This makes it Bold, Confident and Even More Dangerous.
1st:Because, it is blended into normal/every day Content.
2nd: It can pass the quality checks of users and low-quality scanners. Because, nothing out of the ordinary is detected.
3rd: It may be accepted as useful, while in reality it is an ambush. Plus, it reproduce and branches out to several other variants.

Where Does UNIX Or Linux Comes In?

Did You Really Have To Go There?
I mean everything is a file in UNIX Servers
A quick overview:
The following file-system are common on the system:
text files ; executable files (shell scripts or binary files ) ; device files; directories; references to files, etc.

The next best thing is that the list of files & file systems are organized in nested ranks...
With Only One Root Directory:
For example all the drives like: hard disks,CD ROM, DVD,USB;s or floppy disks. Are indicated as specific files in the directory.
The MS-Windows file system, of a UNIX system does not differentiate, between different drives.
The system administrator is responsible for the installation, configuration and system maintenance.

How To Stop Macro Virus Attacks:

Let's face it using mail servers, are unavoidable on a UNIX/Linux Server, therefore you need to download antivirus software to eliminate weaknesses.
Some users may run Windows, Microsoft Office Suite, or other Operating systems.

Solution: Linux Malware Scanners Are Needed:

Scan all documents received, USB FLASH drives, mobile devices, or extension devices.
Use antivirus Software that regularly updates:Detects, Ransomware, viruses, rootkits, worms and Trojan Horses.
Remember not every antivirus software is suitable for Linux, or removing existing and preventing future: Microsoft Office macro viruses, mobile malware, and other badware threats.
The Best Scanners for Linux mail servers is Avast software, to defuse viruses. Before find ACCESS to users that may be using Outlook and Outlook Express mailboxes.
