What is malware?

Malware (also called malicious software) is a term for malicious code, programs or files that can disrupt the normal operation of a system and harm internet users. Malware can break into systems and devices without permission, take control of, damage or disable networks, and interfere with the operation of Website; and plant itself on devices and spy on them...

Once inside your computer, hacker can access and steal your data. They use these methods to steal data and disrupt the whole system.

Malware comes in many forms. The most common are Trojans, spyware, worms and computer viruses.

What kind of attack is a malware distribution attack?

A malware distribution attack is an attack on a computer system through malicious software containing many pieces of code. This software can encrypt or delete data and steal users' sensitive data; change or take over core computing functions, and monitor a user's computer activity without their permission.

With the internet growing so fast, criminals use many sophisticated methods to spread malicious software and attack users, including:

• Sending emails with malicious links to users.
• Hiding malware inside cracked, pirated or otherwise illegitimate software.
• Through pop-ups on website untrustworthy sites that spread malware.
• Hidden on malicious websites, and in game, audio and video files from untrustworthy sites.
• Malware can also spread through peripheral devices such as discs, USB drives and external hard drives.

How does malware work?

When you use Internet, the following actions may leave you infected with malware.

• Downloading games or music files, visiting malicious sites infected with malware, installing toolbars or software from unknown vendors, downloading files that weren't scanned by security software, opening malicious email attachments (malspam).
• Downloading malicious apps disguised as legitimate ones, or ignoring warnings during installation, especially when an app asks for access to personal information and email.
• Downloading apps from untrusted sources.
• Installing bundled extra software (potentially unwanted programs) that contains malware.
• Not using any security software can also make it easier for malware to get in.

Signs that malware has attacked you

If your device is infected with malware, you will notice signs such as:

• Your computer runs very slowly, and the operating system's processing speed drops whether you're browsing the internet or only using local apps.
• Annoying pop-up ads appear, specifically adware.
• The system keeps crashing, freezing or showing a BSOD (blue screen of death) on Windows.
• Disk space drops abnormally.
• Activities internet across the whole system rises with no clear cause.
• System resources are drained abnormally and the computer's fan runs at full speed.
• Your browser's default home page changes without your permission.
• New extensions, toolbars or plugins appear in your browser.
• Antivirus programs stop working and can't be updated.
• A ransom message from malware appears, threatening to delete your data if you don't pay.

Malware uses malicious software

Trojan

A Trojan poses as reputable, legitimate software with features that protect your computer from malicious code and viruses, but it is a form of deception. In essence, a Trojan is a malicious structure that lets malicious code and viruses enter and harm your computer. Its consequences can be severe, as it can destroy a system quickly, before you can get it under control.

Usually, a Trojan infects through malicious content in emails or when users interact with infected websites. It appears as a fake notice that your system is infected with a virus and that you need to run a program to secure it. If attacked, you lose root access. Trojans last longer than viruses, and some statistics show Trojan attacks are more common than any other kind of malware.

Virus

Computer viruses spread very easily across software and hardware. If not dealt with in time, you can lose control of your system and lose data.

Worm

Worms are very hard to remove and clean up after. They can multiply on their own with no outside control or action. Even after being wiped out, a worm can regenerate, so it is hard to get rid of completely.

Malvertising

Malvertising is malicious advertising. When you click on such an ad, its code sends you to a malicious website, which then installs malware on your system automatically.

More dangerous and more sophisticated, criminals can turn well-known, safe websites into carriers of malicious ads, threatening most users.

Phishing and Spear Phishing

This is a phishing-style cyberattack that delivers malware to users through different channels. Common methods include tricking users into clicking URL so they believe they are visiting a bank or another service. In this way, criminals can steal personal information and passwords to steal your money.

Spyware

Spyware is a spying program used to copy and monitor user activity. It is often used by hacker in targeted attacks to steal user data, threaten and extort them. Spyware is easy to remove and does not destroy systems or data.

Rootkit

Rootkits hide malicious code and its activity. Usually it is very hard to tell that your system has malware unless you run antivirus software. The worst outcomes malware can cause are loss of admin control and stolen data and identity.

Ransomware

Ransomware Ransomware encrypts your data and locks you out of your device. To get your data back, you have to pay. This is a fairly common form of malware worldwide.

There are many other malware distribution attacks, in which cybercriminals use sophisticated tricks for different purposes. As network security, operating systems or online trends develop and change, malware also becomes more varied and sophisticated.

How to fix a website infected with malware

If your website is under malware attack, you can fix it in the following ways:

• For open-source systems, check and apply the system's security patches. Updating regularly is one of the most effective security measures developers give users.
• Check and review suspicious data files, and back them up to your local machine before reviewing. Re-upload source code. Then set permissions on all folders with commands such as chmod 444. Avoid chmod 777 to keep security as tight as possible.
• Change your server password, hosting and account passwords. Best to use strong passwords unrelated to your personal information.
• First, remove all the ad code you have placed on the site, because iframe ad code from providers is often flagged as malware by Google.

With the information above, you should now have an answer to the question “What kind of attack is a malware distribution attack?”. Now that you know the basics, do your best to protect your information and personal data to avoid unpredictable attacks from the internet.
