It seems that everyone is obsessed with digital money nowadays. While skeptics say that there’s no need to buy them or waste your time mining virtual currency; other say that virtual money is the future. Unfortunately, we are not fortune tellers and cannot predict whether cryptocurrency will replace banknotes and credit cards. However, we can introduce you to cryptocurrency and leave you to decide whether you want to join the game or not.
The beginning of cryptocurrency
In late 2008, Satoshi Nakamoto released the news about Bitcoin – a brand new peer-to-peer Electronic Cash System. Though, he did not intend to create a world’s most popular digital currency back then. He just wanted to create a decentralized cash system.
However, Satoshi Nakamoto was not the first one who thought about creating virtual money. Though, he was the only one who succeeded and gave the birth to cryptocurrency madness.
Besides, if you thought that Satoshi is the real name of Bitcoin father, you are wrong. His identity is unknown for a decade.
The success of decentralized digital cash system
In the nineties, people were interested in creating virtual money. However, these attempts failed due to the centralized Trusted Third Party based systems. Thus, Nakamoto decided to create decentralized system; and he succeeded.
His created digital cash system that operates similarly to Peer-to-Peer network that is widely used by many people to share files easily. Differently than centralized systems, decentralized does not have a server that keeps records of transactions and balances. Thus, no control is needed.
In the decentralized network, every peer has to have the list of transactions and know the balance of the accounts in order to confirm further transactions. It means that in order to use virtual currency, such as Bitcoins, peers have to reach consensus.
The scheme how Bitcoin transaction operates
Imagine that John wants to send 1 Bitcoin to Jane. Thus, he requests a transaction which is signed by John’s private key. The request is being sent via the whole network. The network peers have to validate his status using specific algorithms.
When it’s verified, the transaction is mixed with other transactions in order to make a block of data. This new block is attached to the existing blockchain, and then the transaction is completed. Jane receives her 1 Bitcoins and is extremely happy.
Therefore, the key of cryptocurrency is confirmation which is performed by miners. For this task, miners are rewarded. Thus, there’s no surprise why illegal cryptocurrency mining becomes so popular.
Anyone can mine Bitcoins, Monero, and other digital money
As we have mentioned, cryptocurrency does not have a centralized authority who would control and confirm transactions. Therefore, in theory, anyone can be a miner. However, virtual money-making business is not that simple. Miners need lots of computer’s power and resources in order to solve a cryptologic puzzle.
Once the device finds the solution to the delegated problem, miner gets a specific amount of Bitcoins or another cryptocurrency. However, solving the puzzles requires lots of computer’s resources and power because these puzzles become more and more complicated. Thus, a miner has to invest in hardware to participate in this “game.”
Illegal cryptocurrency miners try to play around with legit scheme
It seems that everyone is mining Bitcoins nowadays. We will talk more about the reasons for this madness later. Before that, we have to look through the dark part of cryptocurrency mining.
While previously mentioned scheme requires some time and lots of computer resources, dishonest virtual gold diggers found a way how to play around this process. Crooks and cyber criminals created numerous cryptocurrency mining programs that spread as computer viruses. Once these programs infiltrate the computer, they start using device’s resources to mine digital money.
Of course, victims are not informed about this activity. The only thing they might notice is sluggish computer’s performance and suspicious processes running in the Task Manager that might use up to 90% of computer’s CPU.
Cryptocurrency miners might be presented as legit applications
During the past couple of months, security specialists reported about numerous cases when fake applications were spreading illegal miners. Some of the examples:
- The legitimate Coinhive tool was used by cyber criminals who embedded Monero mining code into Google Chrome extension called SafeBrowse. The minute when a user opened Chrome after the installation of this add-on, Monero mining activity is launched.
- Criminals also hacked several websites and injected crypto-currency mining code. Thus, when a user visits such website, mining begins. However, leaving the website or closing the browser not always help to solve such activity.
- One of the recent cases was Monero miner distribution via YouTube ads. Criminals compromised Google’s DoubleClick ad platform in order to display such ads for Japanese, French, Taiwanese, Italian and Spanish YouTube users.
Illegal crypto-currency mining is expected to evolve and grow. Criminals are always looking for new ways and methods to swindle the money from computer users easily. Unfortunately, digital money seems very convenient and attractive for evil-minded people.
Why is cryptocurrency so popular?
One of the main reasons why cryptocurrency is attractive and cyber criminals love it a lot is privacy. No one can track your transactions or check where you spend your digital coins. For instance, if you are using Bitcoins, you are given a specific Bitcoin wallet address which is created from 30 unique characters. No more information needed. Your full name, location and other details are not required.
Thus, this explains why developers of ransomware always demand to pay the ransom in Bitcoins. In this way, they can protect themselves from legal punishment because no one can find them.
However, cyber criminals are not the only ones who see benefits from virtual money. Investors and other people prefer cryptocurrency for these reasons:
- Security – cryptocurrency is locked and encrypted with private keys. Thus, no one can break the scheme or steal your Bitcoins;
- Cryptocurrency is free to use – anyone can download free mining software and start digging virtual gold;
- Global transactions – computers all over the world are connected to the same network and location doesn’t matter. All the transaction can be made worldwide immediately;
- Transactions cannot be canceled – once the transaction is confirmed, there’s no way back. This fact is must remember if you ever consider paying the ransom for ransomware creators and they leave you without promised decryptor.
