1. What is hidden mining?

Scammers can hide the mining virus in any file, up to a torrent, a document or a picture. Getting into the system, the miner bot is installed in the hidden mode and disguised as the Windows registry, so it can remain unnoticed for a long time.

2. The principle of hidden mining

We have already explained how to hide the mining virus, it is time to talk about the basic principles of its work. By infecting a computer, this virus gets access to the processing power of its CPU. After that, it connects to a certain mining pool, which is engaged in cryptocurrency mining using processors. This mining brings a penny from one computer, so the main purpose of scammers is to infect as many devices as possible.

You might have guessed that all the mined money goes straight to the wallets of attackers. Bots can be different, more complex ones can monitor CPU overloads and make adjustments to their work based on this data. That is, if the virus sees that the computer is overloaded, then it turns off the mining so as not to attract unnecessary attention. Some versions of viruses have an additional clone of the source file, which will automatically restore it after uninstallation.

3. How to find and delete the shady mining virus from your PC?

If your computer starts freezing for no reason, although you do not perform any power-consuming tasks, it is already a bad sign that it can be infected with a hidden mining virus. So how do you find the hidden miner? You need to carry out a number of actions:

  1. Test the operation of the device during the execution of simple tasks;
  2. Open more complex programs, such as games;
  3. Run a load test of the graphics card and CPU during operation and after closing background applications;
  4. Analyze the indicators in all of the above loads.

If you find inconsistencies in the system performance report during the above-mentioned tests, then it is likely that your computer is infected with a hidden mining virus.

The next logical step will be to delete it, but this process is not as simple as it may seem at first glance. The fact is that scammers are working every year to improve the algorithms for bypassing the security system of antivirus programs. Thus, the deletion of the bot-miner should be approached with all responsibility. So, how do you delete it?

  1. First, backup all of your important files to an external storage device. It is very important, do not make a full backup of the files, as in this case you will transfer a virus file as well.
  2. Next, install a fresh update of the antivirus software. Additionally, you can install the program CCleaner, it works well in tandem with the antivirus and will increase the chances of completely removing the “program metastases” of the miner.
  3. Before you perform a search on the mining virus, close all applications that run in the background. This is necessary in order to make it easier to recognize malicious software, as it is often masked by the standard processes of the system.
  4. Get rid of all programs or games that were downloaded from questionable sites. After that, run a deep scan of the system for viruses and study all the processes in the task manager, if any of them loads the processor more than 15-20%, then most likely it is the hidden miner.
  5. More complex miners are not displayed in the task manager, and you will  need to download and install a special plugin that neutralizes spyware in automatic mode to get rid of it, for example, Malwarebytes Anti-Malware, CurelT, etc.
  6. If nothing helps, you should perform a full formatting of the hard disk and reinstall the operating system.

4. Conclusion

Many scammers use special viruses in order to use the computing power of multiple computers and mine cryptocurrency in such a way. This leads to inconveniences during the use of a PC, because the system does not work properly. In this article, we learned how to detect a hidden miner on your computer and get rid of it once and for all.

Malware From The Pirate Bay May Hijack Website To Steal Crypto

The movies downloaded from The Pirate Bay bring a malware to the user’s computer. That was the conclusion reached by a security researcher, with the nickname  0xffff0800 in Twitter. He told that when he downloaded a movie ‘The Girl In The Spider’s Web’ from TPB, a .LNK shortcut with CozyBear malware got to his computer.

However, the Cozy Bear malware is just a decoy, the real thing that brings damages is Powershell commands. Once the malware reaches the computer, it carries out malicious actions, like disabling Windows Defender and installing viral extensions in Firefox and Chrome browsers. Moreover, it edits the appearance of the website on the user’s computer.

The movie is an application itself which links the computer to the external malicious servers.

Moreover, the newly installed viral extensions can modify the JavaScript code and add some advertisements to the main page, like it is shown below.

Source: Bleeping Computer

What is the most dangerous is that the malware can edit the appearance of the web page and add or change the information without the user’s awareness, this ability allows the malware to steal the crypto. For example, if the user open Wikipedia page on a compromised system, he/she is likely to see the message saying “Wikipedia now accepts donations in form of bitcoin” and a ‘DONATE’ sign. All the donations will go to the hacker.

In addition, the malware is able to change crypto wallet addresses provided on the pages. Unfortunately, you will not even notice how the hacker stole your money.

Cryptopia Got Hacked, Crypto Exchange Is Suffering “Significant Losses”

One of the best crypto exchanges of New Zealand, Cryptopia, was hacked. It announced this sad news via Twitter stating that it had experienced a security breach that ended in a “significant loss”. However, the company did not mention any figures of the loss.

Cryptopia has suspended all the activities on the trading platform for an indefinite period. In addition, it has notified the authorities of the country, and now it cooperates with the police and the country’s High Tech Crimes Unit in order to investigate the hacker attack.

“Staff then notified and involved the appropriate Government Agencies, including NZ police and High Tech Crimes Unit who are jointly and actively investigating the matter as a major crime and they are assisting us with advice,” the exchange stated.

This is the first cryptocurrency exchange theft in 2019, however, many customers of different crypto exchanges call into question the security of them, as there were so many incidents that had to teach exchanges how to deal with it. Some users even blame the exchanges, in particular Cryptopia, in a bear market “exit strategy”.

The Hackers of the “51% Attack” on Ethereum Classic Returned Half of the Stolen Funds

The alleged organizer of the “51% Attack” on the ETC network transferred back $ 100,000 to Gate.io. bitcoin exchange. It was stated by its representatives on their Twitter account:

As a result of the attack, the users of the Hong Kong Stock Exchange had lost about 46,000 ETC. The representatives of the exchange were going to recover the money lost at their own expense.

However, last Saturday, Gate.io reported that an unknown hacker returned about half of the stolen funds. The company tried to contact the hacker. So far, the reasons he returned the funds have not been clarified since the hacker have not responded.

The representatives of the exchange guessed that if the organizer did not seek to profit, it could be a white hacker who wanted to remind people of the risks. Gate.io also noted that the current hashrate of the ETC network is not high enough, which means that the attack might happen again.

Now a successful transaction in the Ethereum Classic network on Gate.io requires about 4000 confirmations. The exchange is confident that this measure will enhance security and recommends other crypto platforms to stick to such measure to protect traders.

We remind you that despite the significant losses of the Gate.io users, the hackers used a simple hacking algorithm:

“51% Attack” Hit Ethereum Classic: A Full Analysis Of The Process

As we have reported earlier, Ethereum Classic was hit by 51% attack, it means that hackers obtained more than 50% of network’s mining hashrate.

A Malicious “51% Attack” Hit Ethereum Classic, The Loss Allegedly Accounts For $460 000

Slowmist, Chinese-based blockchain journal, has released a full report on the attack. The earliest hit occured on January 5, the culprit hacked some exchanges, like Bitrue, Coinbase, Gate.io, however, this was noticed only two days later.

The first action was a transfer of more than 5000 ETC from Binance to the criminal’s address 0x24fdd25367e4a7ae25eef779652d5f1b336e31da. This amount of coins moved to a mining node, that created block 7254355. After that, the hacker deposited 4000 ETC to Bitrue exchange in block 7254430, yet, this transaction vanished from the Ethereum Classic chain. Another 9000 ETC was stolen in the same way. The Bitrue address 0x2c9a81a120d11a4c2db041d4ec377a4c6c401e69 no longer exists, and the official history is clear. Though, Bitrue managed to save some records:

The scheme of the hacker attack is simple:

  • make a deposit;
  • withdraw to a safe address;
  • to double coins – just move the coins to other addresses.

One of the biggests victims is Coinbase exchange. It was estimated that the loss from the attack accounts for $1 million. The above-mentioned report also provides the information about two attacker addresses which were blackmailed by Coinbase later. They are:

– 0x090a4a238db45d9348cb89a356ca5aba89c75256
0x07ebd5b21636f089311b1ae720e3c7df026dfd72

In Twitter, one of users (nickname: @OGBTC) claimed that he knew the culprit personally.

Another user (nickname: @sebseb7) indicated that it was he who knew the hacker.

The “51% Attack” is over for now. All we can do is to estimate the losses and to take measures so that it will not happen again.

The report also stated:

“[W]e recommend that all digital asset services platform block transfers from the above malicious wallet addresses. And strengthen the risk control, maintain a high degree of attention, and be alert to double spend attacks that may erupt at any time.”

How to Get Bitcoin And How Profitable is Mining in 2019

Appearance of Bitcoin has marked the beginning of a new era in development and dissemination of money. 2018 became a crucial point for cryptocurrencies. In this article we will talk more about Bitcoin mining, find out what is needed and how to earn from it.

1. What is Bitcoin mining?

BTC mining is carried out with the help of specialized computer equipment, so-called Bitcoin farms. In order to open a new block, the miners resolve complex mathematical problems, for which the network rewards them with X number of coins.

Bitcoin algorithm is designed in such way, that every 210 thousand blocks the reward decreases exactly by twice. At the very beginning, miners received 50 coins for each new block, then this number was reduced to 25, and now this value is 12.5 BTC.

2. What are the ways to get Bitcoins?

Bitcoin is the most popular cryptocurrency in the world, many people would like to become its lucky owner. Here are some ways to do it:

– Bitcoin faucets. This is an absolutely free method to get coins. It lies in performing various simple tasks, such as decoding and entering captchas, clicks on advertising links, browsing advertisers` websites, etc. This work is absolutely simple, but it requires  patience. We want to remind you, that reward for such work is purely tokenistic and it is not possible to earn decent money from Bitcoin faucets.

– Mining. This method means investment into equipment. It can be completely different: you can organize home mining on graphics cards spending 2-3 thousand US dollars on it, or you can build a huge data center by investing hundreds of millions of US dollars into this enterprise. Thus the income should be directly proportional to the initial investment. Unfortunately, today cryptocurrency is so volatile that it is impossible to calculate how much profit Bitcoin mining will bring in 2019.

– Salary in crypto. Nowadays, the fact of getting salary in cryptocurrency is no longer supernatural. Yes, it is still uncommon, but it is far from single instance.

– Purchase. The most obvious way to get cryptocurrency is to purchase it. Nowadays, you can buy Bitcoin using a large number of services (exchanges, currency exchange offices, individuals, etc.).

3. What is needed in order to start BTC home mining ?

In general, this is rather a broad theme, but in this article we will only briefly run through the main points, without which home mining is impossible. So you need to:

  1. Buy equipment for mining (graphic cards or ASIC miners).
  2. Create a Bitcoin wallet. Without this it will be impossible to get coins.
  3. Select a mining pool. Nowadays the hash rate (total computing power of all the miners) of Bitcoin network is really huge, that is why the algorithm constantly increases its overall complexity. This is why it will be very difficult for one miner to open a new block even with sufficiently powerful equipment.
  4. Install a special software for mining.
  5. Follow the process and, if necessary, repair or replace the components.

You should also remember that mining equipment (especially ASIC-miners) make a noise and heat up while working, therefore installment of farms in a residential house is not a good idea.

4. What is cloud mining?

There is another way to start mining Bitcoins. This is a cloud mining. It does not involve physical contact of person with equipment. A user buys a certain amount of computing power at a large data center and immediately starts to get income from it. So, how is it better to mine Bitcoin, on your own or using cloud? Everyone will find his own answer. Definitely, profit of home mining will be higher, but cloud mining will ease your pain associated with farm maintenance. Someone is willing to pay for his or her comfort, but another one would prefer to do everything by independently, therefore, everyone decides on one’s own.

5. Which video adapters work best for Bitcoin mining?

Each particular video adapter has its own payback period, which directly depends on what is happening on the cryptocurrency market. 2019 has just started, so here is the list of the most cost-effective video adapters for BTC mining in 2018:

  • NVIDIA GTX 1080 TI.
  • NVIDIA GTX 1070 TI.
  • NVIDIA GTX 1070.
  • RADEON VEGA FRONTIER EDITION.
  • RADEON RX VEGA 56.
  • RADEON MINING RX 470.
  • NVIDIA P106-100 (GEFORCE GTX 1060).

6. How to calculate Bitcoin mining correctly?

Bitcoin rate is very volatile, network hash rate is also unstable, so, it is almost impossible to calculate exactly the mining profit. But there are convenient calculators which will help you to find out at least approximate numbers.

7. What does BTC rate depend on and what will happen next?

Bitcoin price varies in the trading range of USD 4000.00. Bitcoin emission is limited and it amounts to 21 million coins. Over 17 million ones have already been mined. But it is necessary to recall a double decrease in the remuneration for a found block, which occurs every 4 years. It is easy to calculate that over the next 30 years, more than 99% of all coins will be mined, and the remaining 1% will be mined over the next 100 years.

According to the laws of economics, this feature makes Bitcoin a very valuable and, most importantly, a limited resource. Now Bitcoin capitalization is about 70 billion US dollars, and it is absolutely a wasted number from the world scale perspective. Many market experts predict a great future for this coin, for example, John McAfee believes that 1 Bitcoin by December 2020 will be USD 1,000,000.00.

If to take a look at Bitcoin chart for the entire history, one can see approximately the same picture of what is happening: rapid growth, prolonged correction, stagnation after which the cycle repeats. Moreover, every time during the correction, the media “buries” Bitcoin, and the coin after some time again renews its previous records.

8. Conclusion

Bitcoin mining, as of the beginning of 2019, is not a very profit-making enterprise without major initial investment. Bitcoin mining should be considered more like an investment for the future, when BTC becomes a very scarce asset and its value can literally skyrocket. Well, we cannot do anything but wait and actively monitor the developments.

GMO Will Keep On Mining Bitcoins at a Different Location

One of the world’s largest IT companies, Japan-based GMO has published its monthly report regarding its mining activities and the profits coming from them.

We remind you:

Japanese GMO Releases a Monthly Update: What Has Changed As For Mining?

Based on the December’s document, the revenue from mining cryptocurrency has dropped down  significantly which implies that immediate measures must be taken.

One of the biggest pitfalls of mining is the amount of electricity consumed and its high price. Thus, GMO made a decision to relocate its main mining center into a different area, where electricity will cost way less.

We will relocate the mining center to a region that will allow us to secure less expensive power supply,” reads the report.

Moreover, the company refuted all the rumors regarding its alleged plans of giving up mining completely. Since 2017, when GMO first engaged into mining, it has earned massive profits and still sees potential in crypto.

As we may see in the statistical data, the mining reward for Bitcoin increased a lot in the last month of December, whereas Bitcoin Cash suffered a hard fall. But the crash of the crypto market and Bitcoin in particular could not be controlled by GMO and affected its business quite badly, making it “move houses”.
