What is Ramsomware?

Ransomware is a sophisticated piece of malware that blocks the victim’s access to his/her files, and the only way to regain access to the files is to pay a ransom.

There are two types of ransomware in circulation:

Encrypting ransomware, which incorporates advanced encryption algorithms.

It’s designed to block system files and demand payment to provide the victim with the key that can decrypt the blocked content.

Examples include CryptoLocker, Locky, CrytpoWall and more.

Locker ransomware, which locks the victim out of the operating system, making it impossible to access the desktop and any apps or files.

The files are not encrypted in this case, but the attackers still ask for a ransom to unlock the infected computer.

Examples include the police-themed ransomware or Winlocker.

What is Port (computer networking)

In the internet protocol suite, a port is an endpoint of communication in an operating system. While the term is also used for female connectors on hardware devices (see computer port), in software it is a logical construct that identifies a specific process or a type of network service. A port is always associated with an IP address of a host and the protocol type of the communication, and thus completes the destination or origination network address of a communication session. A port is identified for each address and protocol by a 16-bit number, commonly known as the port number. For example, an address may be 'protocol: TCP, IP address: 1.2.3.4, port number: 80', which may be written 1.2.3.4:80 when the protocol is known from context. Specific port numbers are often used to identify specific services. _________________________

What is a localhost ?

In computer networking, localhost is a hostname that means this computer. It is used to access the network services that are running on the host via its loopback network interface. Using the loopback interface bypasses any local network interface hardware. The local loopback mechanism is useful for testing software during development, independently of any networking configurations. For example, if a computer has been configured to provide a website, directing a locally running web browser to http://localhost may display its home page. On most computer systems, localhost resolves to the IP address 127.0.0.1, which is the most commonly used IPv4 loopback address, and to the IPv6 loopback address. _________________________

What is Back Door?

A back door is generally a piece of code intentionally left by the developer of the software or firmware that allows access without going through the normal security process. Back doors may also be the result of different malware/virus attacks that leave a method for remote, unsecured access into a device once the malicious code has been executed. _________________________
