Virtual reality (VR) is an interactive computer-generated experience taking place within a simulated environment. It incorporates mainly auditory and visual feedback, but may also allow other types of sensory feedback like haptic. This immersive environment can be similar to the real world or it can be fantastical; it allows the user to explore and feel
as though they are there, rather than just be a passive observer or consumer of the media content. Virtual reality artificially creates sensory experiences, which can include sight, touch, hearing, and smell. Simulated audio and video devices are sometimes used in conjunction with the other senses.


A short history of VR


What is virtual reality, its definition and its types? – Part 1: History of VR: 1950s-2000s. What is Virtual Reality? Virtual Reality (VR) has been a dream for decades but only in recent years has it become more mainstream with companies like Facebook investing billions into developing technology that allows us to experience things we wouldn’t normally be able to. In essence, VR allows you to immerse yourself in an entirely different world through headsets or other devices that allow you to see and hear everything around you as if you were there.


The origins of Virtual Reality


The definition of Virtual Reality has existed since we created our first video games. The term Virtual Reality was coined in 1987 by Jaron Lanier, a computer scientist who worked for Atari back in 1981.


How does it work?


Virtual reality works by taking advantage of a technology called augmented or mixed reality. The first part of the phrase augmented refers to how virtual reality uses our existing senses—vision, hearing, touch—to enhance our experience in a way that feels real. The second part, mixed or merged reality, refers to how VR blurs lines between what we perceive as real and what we perceive as computer-generated images. The result is an immersive experience that feels like it could be
real.


Oculus Rift DK1


In March 2014, Facebook bought VR startup Oculus VR for $2 billion. At that time, there were a few different consumer-focused virtual reality headsets on the market, but only two were poised to make it big: Sony’s HMZ-T3W ($1,000) and Samsung’s Gear VR ($199). Google Cardboard also makes a compelling case for why every smartphone should have an affordable companion headset.


HTC Vive


The HTC Vive is one of two high-end systems making waves in virtual reality, along with Facebook’s Oculus Rift. The Vive was developed by gaming giant HTC in partnership with Valve.


PlayStation VR


Sony’s PlayStation VR (PSVR) headset offers a relatively affordable way to get into VR gaming. It’s also one of the most accessible ways to experience virtual reality, as it requires no additional equipment beyond your PS4 console and PS4 controller. It also has some of the best games available for any VR platform, including Resident Evil 7: Biohazard, Batman: Arkham VR, Star Trek: Bridge Crew, Skyrim VR, and more.


Google Cardboard


Virtual reality (VR) has been a buzzword for quite some time, but it was with Google’s Cardboard initiative that VR entered everyday conversations. Everyone knows what an ordinary cardboard box looks like, but it’s unlikely anyone would expect to use one as a VR headset. (Virtual reality)

[A]. WHAT IS ETHICAL HACKING?


Moral Hacking is an approved act of bypassing framework security to recognize potential information breaks and dangers in an organization. The organization that possesses the framework or organization permits Cyber Security designers to perform such exercises to test the framework’s guards. Hence, not at all like malignant hacking, this cycle is arranged, endorsed, and all the more significantly, lawful.

Moral programmers plan to research the framework or organization for flimsy parts that pernicious programmers can take advantage of or obliterate. They gather and examine the data to sort out ways of fortifying the security of the framework/organization/applications. Thusly, they can further develop the security impression so it can all the more likely endure assaults or redirect them


[B]. WHAT ARE THE TYPES OF ETHICAL HACKING?


There are various types of moral hacking rehearses since pretty much every part of a framework can be hacked and these ‘hacking’ exhibitions require profound information in regards to that part. Underneath you can track down a rundown of various moral hacking rehearses.

1). Web application hacking

2). Social designing

3). Framework hacking

4). Hacking remote organizations

5). Web server hacking


[C].  14 TYPES OF HACKERS


1). Dark Hat: Criminal Hackers


A dark cap programmer is a cybercriminal who breaks into PC frameworks with a vindictive or criminal aim. Dark cap programmers are likely your thought process when you picture a common programmer or cybercriminal. Their high level of specialized information and capacity to explore the online protection scene makes them so gifted in completing their assaults. They make a special effort to observe weaknesses in PC frameworks and programming, which they exploit for monetary profit or other noxious purposes.

These people can cause genuine damage to people and associations the same by taking delicate or individual information, compromising whole PC frameworks, or adjusting basic organizations.

{”Intentions: To benefit from information breaks”}

Who’s most in danger? Dark cap programmers represent the most gamble to associations, which they ordinarily focus to take delicate information that can think twice about business monetarily.


2). White Hat: Authorized Hackers


Like dark cap programmers, white cap programmers are online protection specialists who utilize their abilities to track down weaknesses in hierarchical organizations and PC frameworks. The vital contrast between them is that white cap programmers are approved to hack these frameworks to recognize security weaknesses before a criminal programmer can.

what-cap programmer definition

Normally recruited by states or enormous organizations, white cap programmers recognize and fix provisos or shortcomings found in hierarchical security frameworks to assist with forestalling an outer assault or information break.

{”Intentions: Help organizations forestall network protection assaults”}

Who’s most in danger? Criminal programmers


3). Dark Hat: “For no reason in particular” Hackers


However, a dark cap programmer is an online protection master who tracks down ways of hacking into PC organizations and frameworks without the noxious aim of a dark cap programmer.

Normally, they participate in hacking exercises for the unadulterated delight of tracking down holes in PC frameworks, and they could even inform the proprietor as to whether any flimsy spots are found. Be that as it may, they don’t necessarily in all cases take the most moral course while utilizing their hacking exercises they might enter frameworks or organizations without the proprietor’s authorization (even though they aren’t attempting to hurt any).

{“Thought processes: Personal satisfaction”}

Who’s most in danger? Anybody who doesn’t need unapproved admittance to their frameworks and organizations


4). Script Kiddies: Ametuer Hackers


Script youngsters are beginner programmers that don’t have a similar degree of ability or skill as further developed programmers in the field. To compensate for this, they go to existing malware made by different programmers to do their assaults.

{”Thought processes: To cause disturbance”}

Who’s most in danger? Associations with unstable organizations and frameworks


5). Green Hat: Hackers-in-Training


A green cap programmer is somebody new to the hacking scene yet is eagerly centred around expanding their cyberattack abilities. They fundamentally centre around acquiring information on the best way to perform cyber attacks on a similar level as their dark cap partners. Their principal goal is to ultimately develop into an undeniable programmer, so they invest their energy searching for gaining potential open doors from more experienced programmers.

{”Intentions: To figure out how to turn into an accomplished programmer”}

Who’s most in danger? Nobody (yet)


6). Blue Hat: Authorized Software Hackers


Blue cap programmers are employed by associations to mess with and test another product or framework network before it’s delivered. Their job is to observe provisos or security weaknesses in the new programming and cure them before it dispatches.

{”Intentions: To recognize weaknesses in new authoritative programming before it’s delivered”}

Who’s most in danger? Criminal programmers


7). Red Hat: Government-Hired Hackers


Redcap programmers are employed by government offices to detect weaknesses in security frameworks, with a particular spotlight on finding and incapacitating dark cap programmers. They’re known to be especially savage in their chase after dark cap lawbreakers, and normally utilize any means conceivable to bring them down. This frequently resembles involving similar strategies as dark cap programmers and utilizing them against them utilizing the equivalent malware, infections and different systems to think twice about machines from the back to front.

Who’s most in danger? Dark cap programmers


8). State/Nation Sponsored Hackers: International Threat Prevention


State/country supported programmers are selected by a country’s administration to get sufficiently close to another country’s PC frameworks. Their network protection abilities are utilized to recover classified data from different nations in anticipation of an expected forthcoming danger or assault and keep a heartbeat on delicate circumstances that could represent a danger later on. These kinds of programmers are recruited exclusively by government organizations.

{”Thought processes: To screen and forestall worldwide dangers”}

Who’s most in danger? Worldwide programmers and hoodlums


9). Malignant Insider: Whistleblower Hackers


Malignant insider programmers are people who utilize a cyberattack from inside the association they work for. Otherwise called informants, their inspiration for assault can fluctuate from following up on an individual resentment they have against somebody they work for to finding and uncovering criminal behaviour inside the association.

{”Intentions: To uncover or take advantage of an association’s classified data”}

Who’s most in danger? Interior chiefs and business pioneers


10). Hacktivists: Politically Motivated Hackers


A hacktivist is somebody who hacks into government organizations and frameworks to cause to notice a political or social reason consequently why the name “hacktivist” is a play on “extremist.” They use hacking as a type of dissent, recovering touchy government data, which is utilized for political or social purposes.

{”Intentions: To reveal insight into a disturbing social or political reason”} (or to offer a political or philosophical expression)

Who’s most in danger? Government offices


11). Tiptop Hackers: The Most Advanced Hackers


Top programmers are the best of the best in the realm of cybercriminals and are viewed as the most elevated gifted programmers in their field. They’re in many cases the initial ones to find the state of the art assault strategies and are known to be the specialists and trend-setters in the hacking scene.

{”Intentions: To perform progressed cyberattacks on associations and people”}

Who’s most in danger? High-income companies


12).  Cryptojackers: Cryptocurrency Mining Hackers


Cryptojackers are known to take advantage of organization weaknesses and take PC assets as a method for digging for digital forms of money. They spread malware in an assortment of ways, frequently by planting irresistible infections across the web. These infections and ransomware-like strategies are utilized to establish malevolent code on casualties’ frameworks, which work discreetly behind the scenes without the casualties’ information. When the code is planted, it sends the outcomes back to the programmer.

cryptojackers-definition

Cryptojackers are difficult to detect since the noxious code can go undetected for quite a while. Since their rationale isn’t to take casualties’ information, yet rather to involve their framework as a vehicle for digital money mining, it’s challenging to follow the wellspring of the contamination whenever it’s found.

{”Thought processes: Cryptocurrency mining”}

Who’s most in danger? Any individual or association with unstable organizations


13). Gaming Hackers


A gaming programmer is somebody who zeros in their hacking endeavours on rivals in the gaming scene. With the gaming business blasting, nothing unexpected but its particular class of gaming programmers has arisen subsequently. Proficient gamers could burn through a great many dollars on superior execution equipment and gaming credits, and programmers normally complete their assaults trying to take contenders’ credit stores or cause dispersed disavowal of administration (DDoS) assaults to remove them from the game.

{”Thought processes: To think twice about contenders”}

Who’s most in danger? High-profile gamers


14). Botnets: Large-Scale Hackers


Botnet programmers are malware coders who make bots to perform high-volume assaults across whatever number of gadgets as could reasonably be expected, normally focusing on switches, cameras and other Internet of Things (IoT) gadgets. The bots work by searching for unstable gadgets (or gadgets that have their default login qualifications flawless) to establish themselves. Botnets can be utilized straight by the programmer who made them, but at the same time, they’re now and again accessible for buy on the dim web for different programmers to exploit.

{”Thought processes: To think twice about the high volume of organisational frameworks”}

Who’s most in danger? People with unstable switches and WiFi-associated gadgets.(cyber security)
