The different kinds of malware and how they can damage your computer.
In computing, malware is any software intentionally designed to cause damage to a computer, server, client, or network.[1] Malware does the damage after it is implanted or introduced in some way into a target’s computer and can take the form of executable code, scripts, active content, and other software.[2][3] The code is described as malicious if it is specifically designed to secretly or illegally take control of, or damage, a computer system.[4]
Malware is not always evil. In some cases, authors write code that causes malicious behavior in order to prevent inappropriate or malicious actions by an automated system,[5][6] or to test the security of the system.[7]
The term “malware” is a portmanteau of “malicious” and “software”.[1][8]
The rootkit is a type of malware that conceals the existence of certain processes or programs from normal methods of detection and obtains administrator-level privileges on a computer or network.[9] A rootkit may replace crucial operating system components and interfere with the BSD Sockets or WinSock layers in order to hide the presence of a network service or process.
A rootkit may implement its capabilities by modifying the kernel modules and system call table, or patching other key binaries, to trap system calls or intercept system calls. It may also modify the properties of Object Manager and process objects to hide processes and threads or factory objects to hide named objects. Rootkits also use end process (EPROCESS) tokens to hide processes from Windows security tools.
A rootkit can be classified as a form of malware that consists of malicious code designed to obtain administrator-level privileges on a computer or network. A rootkit may be used to conceal the existence of certain processes or programs, and it may also interfere with the BSD Sockets or WinSock layers in order to hide the presence of a network service or process.
A rootkit may be used to hide the presence of malware on a system, or it may be used to hide the presence of a specific process or program from normal methods of detection. Rootkits may also be used to modify the properties of Object Manager and process objects in order to hide processes and threads, or factory objects in order to hide named objects. Additionally, rootkits may use end process (EPROCESS) tokens to hide processes from Windows security tools.
A rootkit typically requires access to a system’s administrator-level privileges in order to install itself and perform its activities. Once installed, a rootkit can give an attacker full control over the system, allowing the attacker to install further malware,Steal data, eavesdrop on victim’s activities, or launch denial-of-service attacks.
A bootkits is a type of malware that is installed onto a system’s boot sector in order to ensure that the malicious code is executed each time the system is booted. A bootkit may be used to install a rootkit, which can then be used to give an attacker full control over the system.
A bootkit typically replaces a system’s existing bootloader, which is the software that is responsible for loading the operating system. Once installed, a bootkit can be difficult to detect and remove, as it can interfere with the normal operation of the system.
A bootkit may be used to install a rootkit, which can then be used to give an attacker full control over the system. A bootkit can also be used to launch denial-of-service attacks, or to prevent a system from booting altogether.
A bootkit typically requires access to a system’s administrator-level privileges in order to install itself. Once installed, a bootkit can give an attacker full control over the system, allowing the attacker to install further malware, Steal data, eavesdrop on victim’s activities, or launch denial-of-service attacks.
A botnet is a type of malware that allows an attacker to control a large number of computers that have been infected with the malicious code. Botnets can be used to launch denial-of-service attacks, or to send spam or phishing emails.
Botnets typically consist of a large number of infected computers, known as “bots”, that are controlled by a central attacker. The attacker sends commands to the bots, which then carry out the attacker’s instructions.
Botnets can be used to launch denial-of-service attacks, or to send spam or phishing emails. Botnets can also be used to eavesdrop on victim’s activities, or to Steal data.
A botnet typically requires access to a large number of computers in order to function. Once a botnet is operational, it can be difficult to detect and remove, as the malicious code is distributed across a large number of computers.
A ransomware is a type of malware that encrypts a victim’s files and demands a ransom be paid in order to decrypt the files. Ransomware can be used to encrypt a victim’s entire hard drive, or just specific files or file types.
Ransomware typically uses strong encryption in order to render the victim’s files unreadable. Once the files have been encrypted, the attacker will demand a ransom be paid in order to decrypt the files.
Ransomware can be used to encrypt a victim’s entire hard drive, or just specific files or file types. Ransomware can also be used to encrypt data on removable media, such as USB drives or external hard drives.
A ransomware typically requires access to a victim’s computer in order to encrypt the files. Once the files have been encrypted, the attacker will demand a ransom be paid in order to decrypt the files.
A spyware is a type of malware that is designed to collect information about a victim without their knowledge or consent. Spyware can be used to collect a wide range of information, including a victim’s browsing habits, login details, and financial information.
Spyware typically runs in the background and is designed to collect information about a victim without their knowledge or consent. Spyware can be used to collect a wide range of information, including a victim’s browsing habits, login details, and financial information.
Spyware can be difficult to detect, as it is designed to run in the background and collect information without the victim’s knowledge. Once installed, spyware can be difficult to remove, as it can be integrated into the system.
A spyware typically requires access to a victim’s computer in order to install itself and collect information. Once installed, spyware can be used to collect a wide range of information, including a victim’s browsing habits, login details, and financial information.
A Trojan horse is a type of malware that is disguised as a legitimate program or file. Trojan horses can be used to install other malware, such as viruses, worms, or rootkits.
Trojan horses typically consist of a legitimate program or file that has been modified to include malicious code. When the program or file is executed, the malicious code is executed as well.
Trojan horses can be used to install other malware, such as viruses, worms, or rootkits. Trojan horses can also be used to launch denial-of-service attacks, or to give an attacker access to a system.
A Trojan horse typically requires access to a victim’s computer in order to be executed. Once executed, a Trojan horse can be used to install other malware, such as viruses, worms, or rootkits.
A virus is a type of malware that is designed to replicated itself and spread to other computers. Viruses can be used to damage a system, or to launch denial-of-service attacks.
Viruses typically consist of a small piece of code that is designed to replicate itself and spread to other computers. Viruses can be spread through email attachments, files shared over a network, or by execution of an infected program.
Viruses can be used to damage a system, or to launch denial-of-service attacks. Viruses can also be used to encrypt files or data, or to Stealdata.
A virus typically requires access to a victim’s computer in order to replicate itself and spread. Once a virus has infected a system, it can be difficult to remove, as the virus can spread to other computers on the network.
A worm is a type of malware that is designed to replicate itself and spread to other computers without the need for a user to execute it. Worms can be used to launch denial-of-service attacks, or to send spam or phishing emails.
Worms typically consist of a small piece of code that is designed to replicate itself and spread to other computers. Worms can spread through email attachments, files shared over a network, or by compromised websites.
Worms can be used to launch denial-of-service attacks, or to send spam or phishing emails. Worms can also be used to encrypt files or data, or to Stealdata.
A worm typically requires access to a victim’s computer in order to replicate itself and spread. Once a worm has infected a system, it can be difficult to remove, as the worm can spread to other computers on the network.
