Kenyan Entertainment Blog Caught Mining Monero Using Visitor Browsers

Published

Kenyan blog caught mining monero

On September 27, Nairobi Wire, a famous entertainment blog in Kenya, found itself at the center of attention after it was discovered that they were mining cryptocurrency using their visitor’s computers through a program called Coin-Hive.

Coin-HiveCoin-Hive is a service that makes it possible for people to mine the anonymous cryptocurrency Monero (XMR) directly from a visitor’s computer through the insertion of a JavaScript code within the code of the intended website.

The Pirate Bay First to Use Coin-Hive

This is not the first case where a well-known website has been exposed for such. A couple of days ago, filesharing platform Pirate Bay was caught hijacking its visitors’ browsers for the purpose of mining cryptocurrency. In a statement released by Pirate Bay shortly after the news broke, the company said that it was experimenting with eliminating ads from its website while also finding an alternative way to generate revenue.

On the 18th of September 2017, the same day that Pirate Bay came under attack, Memeburn found itself in the same mess. Memeburn is a multimedia digital publishing house that pays attention to everything digital in the emerging markets. In response to the fiasco, Memeburn pulled down their website and issued a statement through their Facebook page stating that, “we found that a mining tool dubbed Coin Hive was using the website to mine cryptocurrency.” In their defense, they claimed to not have known about it and that they discovered it after “a complaint from a user with regards to high CPU usage when visiting Memeburn.”

Barely a week after Pirate Bay’s admission of mining cryptocurrency using their visitors’ browsers, CBS’ ShowTime found itself in the same rocky situation. ShowTime is an on-demand video streaming service. It is, however, unlikely that for a big corporation like them would intentionally place codes to mine cryptocurrency especially since they charge their users to access their content. It is still unclear on whether ShowTime’s case was intentional or was as a result of their website being hacked as they refused to comment on the matter when contacted by The Register.

Nairobi Wire’s Response

Since the unearthing of the JavaScript code by Coin-Hive on Nairobi Wire’s site, the number of users who have come out to authenticate these allegations has only been on the rise with some claiming that they had gone through the same incident three days before the unearthing. Although Nairobi Wire pulled down the code after it was discovered, some users had already taken screenshots which were circulated on various social media platforms.

In a response to the story published by Techweez about Nairobi Wire mining cryptocurrency through their visitors, they sent a direct message to Techweez via Twitter stating:

“We had already stated on Wednesday that the script was unauthorized. We pulled it down immediately we learned of it. i.e. Tuesday night. We have confirmed that no other mining script is currently running. Between Tuesday and Thursday last week, we had outsourced some maintenance work to an outside developer. It has been our tradition to outsource a big chunk of our design/maintenance work. This means giving outsiders -sometimes foreigners access.”

The response went ahead to say, “We have thus concluded that the said script was installed sometime last week, by our external developer. Nairobi Wire never benefited in any way, and we have now cut links with that particular developer. Our policy of NOT having non-obstructive ads, like pop-up/under remains. This is designed to provide a smooth experience throughout. The mining script falls under ‘obstructive’ ads since it greatly slows down computers and/or can even be damaging to the CPU. We have no plans to use mining scripts now or in the future. If that changes, our readers will be informed and given an option to opt out.”

Business Daily, a leading business publication newspaper owned by Nation Media Group, had also been accused of using Coin-Hive to mine cryptocurrency via the Techweez Forum. And even though the code had already been removed, screenshots of the code on their website had already been captured.

The contentious issue with the above-mentioned cases involving large companies is that they failed to seek their visitors’ permission before mining cryptocurrency using their CPU power. Moreover, only Pirate Bay admitted to having run the code intentionally. With ads being a major pain when consumers are getting access to content on different websites, we are sure they wouldn’t mind letting go of a trifling percentage of their computer’s CPU power if it meant getting an ad-free experience.

With ads being considered a nuisance by many Internet users, there could definitely be a market for this type of revenue generating business model for online publications, provided visitors grant sites permission before giving up some of their CPU power in exchange for an ad-free web surfing experience.

Ethereum: What You Need to Know About the World’s Most Popular Altcoin

Published

on

Popular Altcoin

Consistently seen to be not only the most popular but also the most profitable altcoin – Ethereum deserves your attention.

Well, now that we have your attention, it’s probably important to note that ether, not ethereum is the popular altcoin. While ethereum and ether seem to be used interchangeably most of the time, the fact is that ether is the cryptocurrency that’s associated with Ethereum – a distributed computing platform. To keep things straight if you’re new to altcoins, it’s always wise to seek the help of a trading platform geared towards beginners, like Bitvavo.

Stay with us, it gets weirder.

How it All Started

Vitalik Buterin, a programmer and co-founder of Bitcoin Magazine argued that bitcoin wasn’t reaching its potential. While the well-known cryptocurrency is fairly ideal for processing straightforward monetary transactions, it’s incapable of imposing any type of terms or conditions onto the system of payment. Meaning, that you can send and receive bitcoin, but you can’t request specific tasks to be executed in exchange for these coins. Or you can, but there’s no way of enforcing that either the tasks will be done, or the fees will be paid.

Ethereum

This is where Buterin made clear that he believed that Bitcoin needed a scripting language in order to create applications and contracts and Ethereum was born. While Ethereum began to develop in 2013, it wasn’t released until early 2015. Since that time, Ethereum has stuck to its initial premise of continually updating and upgrading its product to ensure usability, functionality, security, and decentralisation.

As opposed to the Bitcoin hard forks that have created much controversy and less than memorable offshoots of the coin, Ethereum releases prototypes for beta-testing. During beta-testing, the Ethereum network offers “bug bounties” for any users willing to stress test the proposed system update and its limits. Making beta-testing the new platforms incentivised.

While the network has seen their share of hard forks, they exist only in response to cyber attacks, as opposed to differing viewpoints on how the system should work.

Offering What Bitcoin Can’t

The progression of the program itself isn’t the only way in which Ethereum differs greatly from its predecessor, Bitcoin.

Ethereum Virtual Machine

While Ethereum can offer a transfer of monetary value through the use of ether – it’s a unique cryptocurrency – the network is truly designed to be something more. The ethereum network is what is considered a “distributed computing system”.

This means that much like in Bitcoin, millions of computers around the world are connected to a general network. These computers (called “nodes”) all interact with one another via messages or “instruction sets”. These instruction sets identify a common goal that all of the nodes are capable of working on cooperatively. This decentralised network is called the “Ethereum Virtual Machine”.

What makes this virtual machine so incredibly useful and unique is that it’s “Turing-complete”. This means that each computer is capable of understanding, executing, or recognising other types of instruction sets or programming languages. Meaning a computer in Istanbul is capable of simulating the same data requests as a computer in Zimbabwe… or Lima… or Boston, London, Toronto, and so on. Meaning that any node within the virtual machine is just as capable of carrying out a specific task as any other node.

Smart Contracts

This virtual machine really shows its versatility and usefulness when it comes to smart contracts. The name can sometimes be a bit misleading, as these contracts aren’t really “smart” but specifically programmed to execute certain functions without the use of an intermediary.

This is basically just a fancy way of saying that instead of using some human arbiter to ensure the terms and conditions of any agreement are carried out- a computer program does it instead. This not only saves people time and money but is infallible, as one step cannot continue without a previous step being carried out and verified first.

Imagine yourself walking up to a souvenir penny machine. These machines take a penny, squish a fancy pattern on to it, and allow you to bring home a fun piece of nostalgia back from your holiday. In order to get that coveted squished penny, a person must first insert payment (we’ll say about 50 cents) and a penny to be squished. Once the coins are accepted by a machine, the person then chooses their favorite design. The chosen design is then stamped onto the penny and it is delivered to the person.

You can’t walk away with a souvenir penny without choosing a design. There’s no way you could possibly choose a design without a penny to put it on, and you most certainly won’t get that penny accepted to be squished in the first place if you don’t pay your 50 cents. There’s no way to move from one step to another without completing each step in a sequence. This is how smart contracts work. Each term or condition must be met and verified before moving onto the next step. Each step must be completed in the order given to finish out the contract in which each party leaves with their purchase or their money.

Gas Computational Metering

Ether, the cryptocurrency associated with Ethereum, is much more than just another type of digital currency. In fact, it oftentimes works much more similar to a token one that pays for something called “gas”.

Gas is one other thing that enables Ethereum to create novel and dynamic agreements, as instead of paying directly for a service or product, ether is used to pay for the computational effort required in order to execute any specific contract. Much like we a meter to tell us how much we need to pay for water usage, gas is a system of measurement used to calculate the cost of computational effort.

Once the amount of gas required to execute any particular function is computed, a user then pays for that function in ether. However, it is a pay-before-you-go system. So, keeping in mind that gas is simply a unit of measurement, it is applied similarly in the way that you would think about using gasoline to go on a road trip. If you have a destination you’d like to get to, you must first go to a service station and fill up your car’s tank with gasoline in order to get to that destination.

However much gas would be required to fully execute all the steps of a smart contract, from start to finish, is calculated before the computation begins. Ether is then paid to the programmer who will be coding the contract, and as long as you have enough gas in the tank, the contract is then carried out in full.

Brave Rewards: How to Earn BAT Using the Brave Browser

Published

on

Brave Rewards

Chances are you are using an ad blocker on your browser because you find ads intrusive. But did you know there is a free browser that comes with built-in ad and tracking blockers? In this guide, you will learn about the Brave browser and how you can earn Brave Rewards.

What is Brave?

earn bat

Brave Software introduced the first version of Brave in 2016, a web browser that blocks ads and website tracking while allowing users to tip content creators with Brave Rewards.

Advertising websites target the data of users, therefore, infringing on their privacy. Brave is mitigating this issue by offering privacy protection. As a user of Brave, you have the power to choose whether you want to view ads or not. You can earn Brave Rewards by opting into ads that respect user privacy.

Content creators that publish on other browsers like Google Chrome depend on advertisements to make money. However, on Brave, you can tip content creators and support them for their contributions directly.

Here is how Brave stands out:

  • You can turn Brave Rewards and ads on or off
  • Brave ads do not retrieve your personal data
  • Brave picks ads that are suitable for you
  • When you view an ad on Brave, you get 70 percent of what the advertiser paid
  • Ads on Brave appear like system notifications and are, therefore, not intrusive
  • Since brave blocks harmful ads and trackers, you will experience faster browsing

At the end of November 2019, Brave hit more than ten million active monthly users after the release of Brave version 1.0. Like Google Chrome, Brave is based on Chromium, Google’s open-source software project.

How to Start Earning BAT

Basic Attention Token (BAT), the digital currency used on Brave, is based on the Ethereum blockchain. To start earning BAT, follow these steps:

  • Visit the Brave website and click “Download.”
  • Choose the download version that suits your operating system. Brave is compatible with Windows, macOS, and Linux. You can also access the Brave apps for Android or iOS on the same page.
  • Open the application and click “Run.”
  • After a second or two, the application will start downloading.
  • Once the download process is complete, the installation process will begin.
  • When your browser has installed, you can now launch it.
  • Go to the main menu and click “Brave Rewards” then the “Rewards Icon.” Next, click on “Rewards Settings” to enable Brave Rewards.
  • On this page, turn on Brave Rewards and ads.

You can now start surfing the internet and viewing ad notifications as they come. Note that you will receive BAT for viewing the ads not for clicking them. Brave sends an alert on or before the fifth of each month allowing you to claim the Brave Rewards you have earned from viewing ads.

Furthermore, you can choose to hold or tip content creators with your Brave Rewards. To view the BAT you have earned, go to the “Rewards Icon” on the main menu and then click the “Rewards Panel” which will appear on the right-hand side of the address bar.

Brave allows users to transfer their BAT to another wallet where they can convert it to other digital currencies or to fiat and have it transferred to their bank accounts. To do this, you have to link your Brave wallet to your Uphold account.

Besides using the Brave browser, you can also earn a small amount of BAT for participating in the Coinbase Earn Program. The program rewards you in BAT for learning about Brave and BAT.

Scam Alert! Scammers in Kenya are Now Using Facebook’s Libra to Defraud Crypto Users

Published

on

Libra Kenya

Scammers in Kenya are now using Libra to make quick gains from unsuspecting victims through a company called Calibra Kenya.

According to its website, the “company” is promising to increase investors’ money three-fold within six months if they invest amounts from KES 20,000 to KES 950,000. The deadline for this “investment deal” (read scam) is November 31, 2019.

Facebook’s Libra is yet to Launch

Bitcoin Scam“Calibra Kenya” is cashing in on Facebook’s Libra, a cryptocurrency that is not yet rolled-out. Calibra Kenya told Gadgets Africa that they are waiting for the Libra launch in January 2020 for investment to begin. However, it is currently unclear when Libra will launch. Facebook had originally announced 2020 as the launch date but the company has said that it will only launch until it has sorted out regulators’ concerns.

Since Facebook announced the cryptocurrency in June, the embattled crypto project has lost a quarter of its members while Mark Zuckerberg is set to testify before the US House Committee on Financial Services today.

The Kenyan “company” has borrowed the name from Libra’s digital wallet, Calibra.

Scammers That Are Also Self-Proclaimed Philanthropists

“Sir John,” a Twitter account holder promoting Calibra Kenya, claims he is a philanthropist. This is similar to a scam story BitcoinAfrica.io recently covered where the alleged swindler was a self-proclaimed philanthropist on LinkedIn. The aforementioned Twitter account also belongs to the Libra Cryptocurrency Association Kenya.

While scamming and philanthropy have nothing in common, it appears that scammers could have found a way to entice their victims in the name of social good.

Moreover, the fact that Sir John claims he is a nature-lover and a passionate entrepreneur and investor in the fintech industry goes to show how far scammers will go to appear legit.

Spotting the Red Flags

It might be obvious to most that Calibra Kenya is a scam but to some, this might not be the case. Therefore, here is a list of what is wrong with this “investment opportunity”:

  • Libra has not yet launched. Anyone asking you to invest in a currency that does not exist is a fraud.
  • Any individual or company that is promising a 50 percent return every month on investments is a scammer. Such high returns are unrealistic. Additionally, in a volatile market, returns cannot remain constant and are bound to fluctuate from month to month.
  • Facebook’s Libra only has one association, the Libra Association, which currently has 21 members. These members are well-known international companies like Uber, Spotify, Vodafone, Mercy Corps, Xapo Holdings, PayU, and Coinbase. Libra Cryptocurrency Association Kenya and Calibra Kenya, therefore, have nothing to do with the real Libra Association.
  • Should you consider a website with grammatical errors suspicious? Yes, you should! Calibra Kenya’s website is guilty in this regard.
  • According to Calibra Kenya, investors will get their money back at the end of the contract. This is a cause for alarm as any legit investment platform should allow investors to withdraw their investment plus returns at any time.
  • On their website, Calibra Kenya throws around crypto and blockchain-related terminologies to confuse and mislead their readers. For instance, they claim that they create smart contracts, that they are the official Libra cryptocurrency exchange in Kenya, and that they are a tier two member of the Libra Association. This does not make any sense and is only meant to confuse readers.
  • The website contains a lot of payment information which is another red flag. It indicates they are only focused on making money.
  • Their website is too “salesy.” Words like “investment opportunity,” “invest now,” and “we make your dreams a reality” are obvious red flags.
  • Calibra Kenya does not provide a platform for investors to track their investments. That means that once you send them money, you have no way of finding out how your investment is performing. The only mode of contact is a phone number that they could easily disconnect.

Unfortunately, reports of crypto-related scams are increasing as major developments take place in the industry. Similar fraudulent websites also appeared during Telegram’s token sale, for example.
