Whois & Analysis for bullguard.com

Ransomware is computer malware that installs covertly on a victim's device (e.g., computer, smartphone, wearable device) and that either mounts the cryptoviral extortion attack from cryptovirology that holds the victim's data hostage, or mounts a cryptovirology leakware attack that threatens to publish the victim's data, until a ransom is paid.

Simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, and display a message requesting payment to unlock it.

More advanced malware encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them.

The ransomware may also encrypt the computer's Master File Table (MFT) or the entire hard drive.

Thus, ransomware is a denial-of-access attack that prevents computer users from accessing files since it is intractable to decrypt the files without the decryption key.

Ransomware attacks are typically carried out using a Trojan that has a payload disguised as a legitimate file.

Spyware is software that aims to gather information about a person or organization without their knowledge, that may send such information to another entity without the consumer's consent, or that asserts control over a device without the consumer's knowledge.

Malware, short for malicious software, is any software used to disrupt computer or mobile operations, gather sensitive information, gain access to private computer systems, or display unwanted advertising.

Before the term malware was coined by Yisrael Radai in 1990, malicious software was referred to as computer viruses.

The first category of malware propagation concerns parasitic software fragments that attach themselves to some existing executable content.

The fragment may be machine code that infects some existing application, utility, or system program, or even the code used to boot a computer system.

Malware is defined by its malicious intent, acting against the requirements of the computer user, and does not include software that causes unintentional harm due to some deficiency.

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.

Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.

In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface.

Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

A virtual private network (VPN) is a virtualized extension of a private network across a public network, such as the Internet.

It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.

Applications running across the VPN may therefore benefit from the functionality, security, and management of the private network.
