Linux based operating systems also have additional security patches that are updated regularly to keep it safer.
The userbase of Linux is tiny when compared to Windows. While Operating systems like Windows and Mac house all kinds of users, Linux is inclined more towards advanced users. In the end, It all comes down to the caution taken by the user.
However rare they are, they still exist. A lot of people installed Ubuntu for the sole purpose of having a dependable OS when it comes to the security of their data and sensitive details. One more thing to ponder upon is the fact that Linux servers can get hit by malware just like any other server. The desktop version of Linux is highly safe, but the servers can get infected if infected files hit them.
This is a simple case that can be fixed very easily in Linux. Antivirus is not necessary on Linux based operating systems, but a few people still recommend to add an extra layer of protection. You can still add antivirus software for additional security and mental satisfaction. It suffers from the same problems as all ELF viruses. Lindose was also known as Winux and PEElf. It was another proof-of-concept virus, showing how a virus can be constructed to infect both Windows and Linux computers.
It has never been seen in the wild. Made in March Wit apparently released December , another proof-of-concept by the looks of it. Zip Worm passes by infection of. When run, the virus infects all other. It has no other ill effects. From , it is unlikely you'll ever run across it.
It scans the network for computers with open ports, tries the attack, infects web pages hosted on the system and propagates further. This worm is not dangerous to you because the buffer overruns have been patched for years and you do not have any open ports. A back-door is installed and the worm propagates itself. This worm is not dangerous to you because the methods of attack are also from and have been long patched.
Even if the weren't patched, you don't have these services running on your Ubuntu system. The Cheese Worm used a back-door which was installed by another worm.
The Cheese Worm then removed the back-door and propagated. It was an attempt to clean an already infected system. This worm is not dangerous because the worms it needed to propagate are no longer dangerous. Whether it was ever dangerous in the first place is debatable.
The worm could only propagate if a compiler was present on the system. The vulnerability this worm used has long been patched.
OpenSSH is not installed on your system by default. Kork uses the Red Hat Linux 7. That website no longer exists. Red Hat 7. You are safe. Lapper has no information about it at all, anywhere, so I can't give you any information about it, but it was added to the list in , and any vulnerabilities it exploited have almost certainly been patched by now.
I can't say for certain whether this worm could affect you or not, but most vulnerabilities are patched within days, not weeks, so two years makes it very unlikely you could be affected by this.
The L10n Worm pronounced "Lion" was active in and used a printer server for exploit. The vulnerability has been patched and the server is not installed on Ubuntu. This is no danger to you. The Mighty Worm appeared in and used a vulnerability in the secure session module of the old Apache web server, installing a backdoor and joining an IRC botnet. This vulnerability has been patched, Apache is not installed on your system, and the entire architecture of the web server has changed.
You can never get infected. Millen discovered 18th November It replicated to Linux systems on Intel platforms and used remote exploits on four different servers to spread to vulnerable computers. If it succeeded in exploiting a system, it spawned a shell on the system to retrieve the mworm. It then uncompressed the contents of mworm. Ramen apparently spread in January attacking only RedHat systems, not our Debian family. An unusual feature of this worm was its calling card that made infected systems easily identifiable: It replaced all files on the system named "index.
You can't get this one, either. SSH Bruteforce was apparently being developed in but seems to have never reached even alpha release, let alone beta-testing! That's the entire list of Linux viruses and worms.
Fewer than thirty. Compare that to the estimated , viruses for Windows, and you'll understand why people say you don't need a virus scanner on Linux.
The Reality If you are going to trade files in a Windows world, you'll need to scan those files for viruses. However rare they are, they still exist. The short answer is no, there is no significant threat to an Ubuntu system from a virus.
There are cases where you may want to run it on a desktop or server but for the majority of users, you do not need antivirus on Ubuntu. In that window, type sudo apt-get install clamav. It will ask for your password. Linux malware includes viruses, Trojans, worms and other types of malware that affect the Linux operating system. Linux, Unix and other Unix-like computer operating systems are generally regarded as very well-protected against, but not immune to, computer viruses.
It is one of the best OS for hackers. Basic and networking hacking commands in Ubuntu are valuable to Linux hackers. Vulnerabilities are a weakness that can be exploited to compromise a system. A good security can help to protect a system from been compromised by an attacker. Some people believes that Linux still has a minimal usages share, and a Malware is aimed for mass destruction.
