These acts can range from piracy to identity theft. A black hat is often referred to as a "cracker". The term originates from 1950s westerns, with "bad guys" (criminals) typically depicted as having worn black hats and "good guys" (heroes) wearing white ones. In the same way, black hat hacking is contrasted with the more ethical white hat approach to hacking. Additionally, there exists a third category, called grey hat hacking, characterized by individuals who hack, usually with good intentions but by illegal means. Description Criminals who intentionally enter computer networks with malicious intent are known as "black hat hackers".

WannaCry Ransomware Attack
The WannaCry ransomware attack was a worldwide cyberattack in May 2017 by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the form of Bitcoin cryptocurrency. It was propagated using EternalBlue, an exploit developed by the United States National Security Agency (NSA) for Microsoft Windows systems. EternalBlue was stolen and leaked by a group called The Shadow Brokers (TSB) a month prior to the attack. While Microsoft had released patches previously to close the exploit, much of WannaCry's spread was from organizations that had not applied these patches, or were using older Windows systems that were past their end of life. These patches were imperative to cyber security, but many organizations did not apply them, citing a need for 24/7 operation, the risk of formerly working applications breaking because of the changes, lack of personnel or time to install them, or ...

Pay-per-click
Pay-per-click (PPC) is an internet advertising model used to drive traffic to websites, in which an advertiser pays a publisher (typically a search engine, website owner, or a network of websites) when the ad is clicked. This differs from more traditional advertising, which usually requires upfront payment regardless of engagement.

The process of building links should not be confused with being listed on link farms, as the latter requires reciprocal return links, which often renders the overall backlink advantage useless. This is due to oscillation, causing confusion over which is the vendo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
