Malware Overview
What is Malware?
Malware, short for malicious software, is a type of computer program designed to damage or disrupt a system.
It can be used to steal data, install other malicious programs on the system, and even take control of the entire machine.
Malware can come in many forms including viruses, worms, Trojans horses, spyware and adware.
Common Types of Malware
1. Virus: Viruses are one of the most common types of malware. They are typically spread through email attachments or downloads from infected websites.
Viruses can make copies of themselves and attach them to other files or programs on your computer. These copies can then be spread through networks or removable media like USB drives.
Viruses can cause a variety of problems, including deleting files, stealing information, and corrupting data.
2. Worms: Worms are similar to viruses, but they do not need user interaction in order to spread; instead, they exploit vulnerabilities in operating systems and network protocols in order to propagate themselves without any help from users.
3. Ransomware: Ransomware is a type of malicious software that blocks access to a computer system or its data until a ransom is paid. It is typically spread through phishing emails, malicious attachments, or through malicious websites.
Ransomware can encrypt or delete files and can even lock down the entire system, making it impossible to access. When victims are infected, they are typically presented with a ransom demand, which they must pay in order to regain access.
They usually spread by taking advantage of weaknesses in services or operating systems. They can be used to launch denial-of-service attacks, install more malicious software, or steal data.
4. Trojan: Trojan Horses are another form of malware that masquerades as legitimate applications but contains hidden code that allows attackers access into your system when you download them onto your device.
They can be used to gain access to a computer system, often without the user’s knowledge or permission.
Once installed, Trojans may allow attackers to gain access to sensitive data, modify system settings, and launch other malicious programs.
5. Spyware: Spyware is malicious software that is installed on a computer without the user’s knowledge or consent. The main purpose of spyware is to monitor and collect data about the user and their activities. The information is then used for different things, like advertising and marketing, stealing data, and stealing people’s identities. Spyware can also be used to access personal information, such as bank account numbers and passwords.
6. Adware: Adware is software that displays unwanted advertisements on devices it has infiltrated via downloads or pop-ups online ads .
It is usually installed without the user’s knowledge or permission and can be used to deliver targeted advertisements and gather user data.
It can be used to monitor online activities, steal sensitive information, or interfere with normal computer operation.
7. Rootkits: Rootkits are malicious programs that can gain access to a system and remain undetected. They can be used to install backdoors and other malicious software, and can also be used to hide files, processes, and other system components from detection.
8. Keyloggers: Keyloggers are malicious programs that record keystrokes and send them to attackers. They can be used to steal passwords, bank account information, and other sensitive data.
9. Cryptojacking: Cryptojacking is a type of attack in which malicious code is inserted into a website or application to mine cryptocurrency without the user’s knowledge or consent. Cryptojacking can be used to slow down a user’s system and reduce its performance.
10. .Fileless malware: .Fileless malware is malicious software that operates without placing any executable code on the victim’s computer. Instead, it uses processes and applications that are already running to run malicious code, which makes it hard to find.
Fileless malware can be used to steal data, launch distributed denial-of-service attacks, and conduct other malicious activities.
How Does Malware Spread?
Malicious software often spreads through email attachments containing malicious links which lead users to download the virus onto their machines unknowingly.
This method is known as phishing attacks because it tricks people into clicking links that appear legitimate at first glance but actually contain malicious code within them.
Additionally, some websites may also have been compromised with malware already embedded within them; if you visit these sites, you risk downloading malicious content onto your device without realizing it.
Finally, removable media such as USB drives may also be used by attackers to distribute malware since they allow for easy transfer between computers.
Malware is a dangerous threat to any business or individual, so it’s important to understand the different types of malware and how they spread.
