Blockchain comes to the rescue, Blackhat hackers in trouble

Hacking had always been a big issue for industrialists and businessmen. Hackers illegally hack into computer systems and steal important information and identities.

Nevertheless, hacking is not always evil. Sometimes it is done to find interesting ways to solve problems, maximize hidden features and other educational stuff. There exist two types of hackings known as “Whitehat hacking” and “Blackhat hacking”. As their names hint the first one is non-malicious kind while the other one is malicious.

The Hacking is also referred to an easy or convenient way of dealing with something, for example; life hacks. However, in digital terms, it means unauthorized invasion into a computer system.

The Blackhat hackers are more visible than the white ones and can be pretty dangerous. They hack into your digital systems, steal your data and then sell it to some third parties or sometimes even blackmail you by keeping your data hostage and asking for ransom.

Earlier this year a cyber attack is known as the “WannaCry ransomware attack” affected almost 300,000 computers. The ransomware cryptoworm targeted computers running the Microsoft Windows operating system by encrypting their data and demanding $300 to $600 in Bitcoin cryptocurrency, as ransom.

Another attack frequently used by these blackhat hackers is DDoS. They have long been using networks of zombie computers or botnets to attack in form of DDoS (denial-of-service). The hacker controls the botnet and then simply floods websites with a huge amount of data requests.

Although the blackhat hacking is an illegal, vicious business, yet it is extremely profitable. Such hackers earn hundreds and thousands of dollars per year by selling stolen data or by demanding ransom.

Massive DDOS attack

The blockchain community is trying its best to keep the cyber world healthy and secure. This approach is taken by Gladius, a blockchain startup that is a decentralized network for DDoS protection and content delivery.

Gladius empowers everyone to fight against cyber evil in an innovating way. It offers a distributed, peer to peer network where thousands of computers across the globe, share their excess bandwidth and resources to fight against DDoS.

The Gladius network works as a global CDN as well as a DDoS protection provider. The network sits between a server and the clients that access websites. During a DDoS attack, the extra bandwidth is used to deflect and absorb the bad traffic from botnets, thus negating the impact of DDoS.

During ‘peace time’ when there are no DDoS attacks, this same network acts as a global content delivery network, which catches website content across its global network of nodes and speeds up webpage loading and online services.

Now anyone having a computer, fast broadband connection and a spare bandwidth can contribute in this fight against DDoS. Whereas, website owners can now get DDoS protection as well as accelerated websites without spending thousands of dollars.

It’s like turning their spells back on themselves. You just make your computer a part of an anti-DDoS network, while getting paid for it.

Blackhat hackers usually use scripts and codes to take over ordinary computers so they can be unknowingly remote-controlled as part of a botnet. Businesses have lost an average of $2.5 million per such attack.

The bad hackers may be more in number, but that does not mean the good ones are weak or defeated. Fortunately, many skillful hackers have chosen the whitehat path.

Such law-abiding hackers earn their living by providing security services in penetration testing and security consulting.

According to the Infosec Institute, a certified ethical hacker earns an average of $71,331 a year. They can also earn additional income from company-sponsored bug bounties, on the freelance basis.

Companies host their own bug-capturing programs, where whitehat hackers check for vulnerabilities and get paid for reporting one.

According to Bugcrowd, businesses have so far paid out ‘$6 million’ for bug bounties, since 2017 started, which is already a 211% increase from last year’s figure.

Bug bounties are mostly fragmented, underscoring the potential of an ecosystem for whitehat hacking. Beyond simply establishing a marketplace, a fair and decentralized one might be more beneficial, especially in the security community.

A startup named, Hacken established a community for whitehat hackers to nourish the connection between blockchain and cybersecurity communities. It is centered upon HKN, an Ethereum-based token serving as cryptocurrency for whitehat hacking services. The token will be sold from 31st October, with a sale length of one month.

“Our goal at Hacken is to lay down the future white hat cybersecurity community framework of Eastern Europe by creating a stable means of income and financial incentives for its members,” its founders state on the Hacken whitepaper.

While its focus on Eastern Europe, the platform supports ethical communities from all over the world, as is the nature of blockchain.

With growing problems and emerging cyber dangers, blockchain startups like Gladius and Hacken are stepping forward to help eliminate these issues, whether they are basic or highly technical.

Such startups are striving hard to create a pure and transparent cyber world through faster and more open exchange of value and services. Thus, making it hard for the blackhat hackers to continue their impure business.
