What is cryptojacking?


There’s been some talk about this on social media for a while, I also reported about it in my weekly podcast a few times too, well now it’s time to elaborate on it.

So, what is it?

It’s a term that describes an act of hijacking someone else’s CPU to mine cryptocurrencies. Ever since the first reports started circulating about The Pirate Bay doing it, Cryptojacking has become a “thing” in the past 6 months and the trend is spreading out.

A number of apps started appearing in 2017 making it easier than ever to mine crypto with phones, tablets or laptops. Coinhive seems to be the tool that came out first and gave birth to the trend but since then we saw a great deal of phone apps or Chrome extensions popping up and the trend keeps growing. The extensions will soon be banned according to Google. The key issue here is the lack of transparency and the intrusive manner this is being executed upon.
In its nature, Cryptojacking is profitable and is on its way to becoming a popular trick for blogs and websites to generate revenue, some use it as an alternative to the old-school ads (banners, pop-ups and in-between) which are way too spammy, messy and in effect, not very profitable compared to results reported from crypto mining.

I call it a trend because a few video streaming sites and the abovementioned file sharing network The Pirate Bay have allegedly been “cryptojacking” their users’ computers in this way, as has the free WiFi provider in a Starbucks cafe in Argentina. Users may object to this, especially when it slows down their computers. The Pirate Bay claims they only tested the option briefly, but that was enough to inspire many others to follow suit. Only a few weeks later, Pirate Bay has also turned on the mining again. Thier team previously said that they were testing the miner to see if it can replace ads. While there is some real revenue potential, for now, it’s running in addition to the regular banners. It’s unclear whether the current mining period is another test or if it will run permanently from now on but given how hard it is for most companies to make money from online advertising, this might be something we have to get used to….(I hope not).

How does it work?

In-browser cryptojacking uses JavaScript on a web page to mine for cryptocurrencies.
JavaScript runs on just about every website you visit, so the JavaScript code responsible for in-browser mining doesn’t need to be installed.
You load the page, and the “in-browser mining code” just runs. No need to install, and no need to opt-in.

Currently (Mar 2018), in-browser mining is mostly used to mine Monero. This is why we are seeing a lot of reports about random hacks on people’s computers (some businesses too) where Monero is being mined. Just last month a shop window in London was hacked for this purpose. Another curious case was a nuclear power plant in Russia earlier this year (2018).

Hidden mining software may be embedded in an ad using JavaScript code. Hackers have even found ways to inject the scripts into websites like Politifact.com and Showtime, mining money for themselves off of another site’s traffic.
It’s common for the code to run on the website without the user noticing it.
Users who have been hit by cryptojackers often complain of a slower internet connection and slower processing speeds.
It can also drain a computer’s battery much faster than normal.

What can I do to keep safe?

If you want to prevent your computer from being cryptojacked you need a software tool which checks the code as it runs such as an ad-blocker.

Currently there are a number of Chrome extensions that are available. Check out “No Coin” – seems to be the most popular one. Also you might want to add a standard Ad blocker too, just to enhance your experience. Not only it blocks trackers and annoying banners but also it removes those super-annoying YouTube ads and save those 3 seconds every time… ah bliss.

Also, you can switch to using Opera or Epic browser instead of Safari or whatever else you have there by default (you can always transport all your bookmarks so no need to feel attached to the old, just saying). These are coming with an a coin blocker function  now.

To find out if your current browser is vulnerable, you can run a check at https://cryptojackingtest.com. They are pushing the Opera Browser there but you don’t have to feel obliged to use that one, here’s my Chrome browser result after I added No-Coin extension.


Good luck with this and hopefully this post helped you. If yes, be good and share it with your friends or at least those of them who may need it.

3 Steps To Limit Your Facebook Data

Facebook is increasingly under public scrutiny for compromising its members data and in the wake of the growing concern of keeping your data to yourself, I have a couple of quick tips on how to limit the data being stored about you.

Facebook now lets you delete anything from your timeline for good. This means it won’t be able to share it with third parties.

Here are 3 ways you can protect your information.

  1. Go to Settings at the top right of your screen, next click on Activity log to see an over view of everything you’ve done on the social network in one spot and delete as you go.
    Android users take a note: Facebook can collect information from your messages and conversations if you’re not careful.
  2. Go to Settings and click on Apps / Facebook / Permissions and make sure Telephone and SMS are Off.


3. Set limits on advertisers. Go to Settings / Ads And check your information. Here’s everything advertisers know about, so Opt Out of what you don’t want to share. And don’t forget your Categories option, too. Under Ad Settings you can even control the type of ads you get targeted with on Facebook.

How to update your Firmware on Ledger Nano S

Recently the Ledger Nano S, my favourite device for safe, offline Bitcoin storage released an upgrade to their firmware which deals with a security issue that was noticed some time in late 2017. There are other fixes and improvements, so it is a must-do.

I received a lot of requests to make a tutorial about updating your firmware on Ledger Nano S and here it is:

If you don’t have the Ledger Nano S, check it out, it is my top choice for hardware storage for Bitcoin, Ethereum, Litecoin, Stratis, Neo, PIVX and a bunch of other alts.

ETC – Callisto airdrop notes

In this post I will provide some tips on how to claim the ETC hard forked Callisto (CLO) coins that you are eligible to receive if you hold Ethereum Classic (ETC) in the right wallets prior to block 5,500,000

What is Callisto and should you care?

Callisto introduces a Cold staking protocol that rewards coin holders for being network participants. “Cold staking is a smart-contract based process that allows CLO holders to earn interest in a total CLO emission when they hold CLO coins at their balances for long enough period of staking time (1 month by default). Cold stakers are not required to run a node to participate in cold staking process. Cold stakers are not validating transactions and the whole system can remain fully PoW (Proof of Work) which is important since ETC adheres to POW consensus.”  (quote from Callisto Networks)

For more details and clarity about this project and to get your hands on its whitepaper, refer to this post on Github.

When will the airdrop fork happen?

You can check https://gastracker.io/ for the current block height.  According to calculations, this airdrop will occur between the 2nd and the 5th of March 2018.


Ethereum Classic (ETC) holders will receive a 1:1 ratio of CLO coins. 

Right now as I write this article, the Ethereum Classic Blockchain last block is 5476170.

In addition, the present price of $36.94 is relatively inexpensive due to the moderately bearish market. I am not giving you financial advice, definitely not suggesting that you go and buy ETC now. This is a guide mainly for those who are already hodlers of ETC and wish to benefit from this airdrop.

What exchanges will support the hard fork?

Currently only Yobit and Coinomi have indicated support. No other exchanges have announced an official stance on the Ethereum Classic / Callisto coinswap fork, so don’t take the chance, make sure you keep your ETC in Coinomi or in a wallet where you own the private key so you can use that private key later and claim your free coins from this airdrop.

Which wallets will support the hard fork?

These three wallets are guaranteed to issue the Callisto coins:

MyEtherWallet(MEW) – it is not yet sure if the MEW developers will support Callisto. Most recently there are rumours that they might not, so I would use ClassicEtherWallet and you can actually use it with your MEW address too so no worries.

Regarding ClassicEtherWallet it should be fairly simple and straightforward to receive your CLO tokens automatically (no need to do anything) and immediately after the hard fork coin swap has occurred.

It is claimed that every ETC account address that has ETC in its balance will receive the equivalent amount of CLO automatically when Callisto launches. You will just unlock your wallet and see your CLO are already here… or at least that’s how it should happen.

As usual, my top choice is Coinomi which supports tons of alt coins and although it’s only for Android at the moment, it is really a great wallet to have. It will make your life easier for future forks and airdrops too, so definitely worth getting that app. Time to move away from that iPhone I guess. Crypto and Apple isn’t exactly a great match. #justsayin’

Good luck with this airdrop everyone! Stay profitable.

Keeping safe online

It’s a serious challenge – cyber security.

The problem is, we aren’t very good at it. This is why I am sharing some of my personal experience and tips on how to make things a bit more secure. Watch my video post here:

Cyber Security is hard to achieve. We are ever more vulnerable to attacks online, especially when working with crypto, which is largely unregulated and there’s no refund policies.

While you can never be 100% hack-proof, here are some tips on how to make your password more secure and other tricks to avoid being an easy victim.
