Mining-Trends in Malware 2018: Amateur Cryptojacker and Apple Macs

2017 was a big year for crypto-jacking. The number of cases increased 8,500 percent, as Figures show, published by Symantec in March. And it seems that 2018 was an even bigger year for Mining Malware. The report of the Cyber Threat Alliance in September revealed that crypto-jacking from 1. January could still grow another 500 percent.

Behind this simple Overview of the growth of a larger and more complicated picture, however. Despite reports from some quarters indicate that Mining-Malware-detections have increased in the first two quarters of the year 2018, it says in other Reports that you had gone back in reality.

And while the General growth of Mining Malware is kept since the last year on the volatility of the crypto currency rates and the Occurrence of Software Bugs back, also have played other factors play a significant role. Examples of this are the participation of Amateur Cryptojackern and the costs for legitimate Mining.

Amateur Cryptojacker

If there is this year, a dominant Trend in the world of crypto-jacking, then the fact that most of the Mining Malwares are aligned with Monero, it is. Palo Alto Networks revealed in July that Monero accounts for 84.5 percent of all the detected Malwares, In the case of Bitcoin, there are in comparison, 8 per cent and other Coins of 7 percent.

There is a simple reason for this: Monero (XMR) is not only a privacy Coin, but also the most valuable privacy-Coin by market capitalisation - and in 10th place overall. He uses the crypto night Proof-of-Work (PoW) algorithm, and mixes the input from the user with those of other users. He also used so-called "Ring-Confidential-transactions", with which the amount of transferred XMR defaced. He is, therefore, ideal for cyber criminals.

Monero was already in 2017, the most popular Coin for Cryptojacker, but in 2018 a number of new developments have been added, making this year from the previous. Especially crypto-jacking increasingly to the domain of Amateur hackers, through cost-effective Mining will be Malware, and by the clear profits in this illicit activity, lured. According to the Russian cyber security firm Group-IB, the Darkweb is flooded "with cheaper Mining Software", which is often for only $ 0.50.

Such types of Software are this year Abundant: In the year 2017 Group-IB discovered 99 sale ads for crypto-jacking Software in underground forums, while the company counted in the year 2018 477, which corresponds to an increase of 381.8 per cent. The company notes in its report:

"A barrier to entry are low in the illegal Mining market leads to crypto know currencies of people with no technical expertise or experience with scammers is gemint systems."


in other words, crypto-jacking has become a kind of hobby crime, which is popular with Thousands of Amateur hackers. This explains, perhaps, why it has come this year to a significant increase in terms of discoveries. Kaspersky Labs has informed Cointelegraph this the fact that the number of PC-crypto-jacking victims of 1.9 million in the year 2016/17 increased to 2.7 million in the year 2017/18. Evgeny Lopatin, Malware Analyst at Kaspersky Labs.

said: "The Mining model is easier to activate and more stable than other attack vectors. It attacks the victim, mint discreetly crypto-currencies with their CPU or GPU performance, and transforms them through legal exchanges and transactions in real money."

of Course, the thought might arise, that if one speaks of "detections", it is quite possible that an increase in the detections is largely due to an improvement of the detection measures. "However, this is not the main reason, as we see actual growth," says Lopatin.

"Our analysis shows that more and more Criminals are crypto miners use increasingly for malicious purposes around the world."

McAfee noted in a report in April that its detections are predominantly CoinMiner was found. This is a Malware which sneaks secretly Code from the CoinHive XMR Mining algorithm on the Computer of the victim. This happens when the victim downloads an infected file from the Web. In the year 2018, there are rivals, however, the novelty is that such a weak Macs from Apple now, which were previously considered to be much safer than your Windows.

This development was noted by the US security firm Malwarebytes, the miner reported in a Blog Post in may about the discovery of a new malicious crypto that uses the real XMRig-Miner. Thomas Reed, the Director of Mac in the enterprise, wrote:

"often, Mac will install Malware such as through fake Adobe Flash Player Installer Downloads from piracy sites and decoy documents, the user to Open the lead."

in fact, this was not the first Mac-Mining Malware that was discovered. Reed explained that the company "other crypto-observed miners for macOS, such as, for example, Pwnet, CpuMeaner and creative update".

Although crypto-jacking is more likely to become one of the Amateurs running phenomenon, it is still a fact that many of this year's attacks on the very "elitist" sources can be reduced. The cyber security firm Proofpoint reported at the end of January, have spread Smominru, a crypto-jacking Botnet of over half a Million Computer. Especially the National Security Agency contributed to the had discovered a Windows error, which was then leaked online.

This vulnerability is better known as eternal blue, which was known for the WannaCry-Ransomware attack in may 2017 responsible. And according to the Cyber Threat Alliance (CTA) is another important factor for this year's increase in the crypto-jacking to 459 percent.

it is of Concern that the CTA indicates that the report to the fact that crypto-jacking is likely to increase only if this activity is successful and profitable:

"The inflow of Money through crypto-jacking could be used for future, more complex actions of dangerous groups. For example, several large crypto-introduced-Mining Botnets (Smominru, Jenkins, Miner, Adylkuzz) millions of dollars."

And it is currently bad enough. The CTA writes also, that the infection is connected by means of Mining Malware with high costs for the victims.

"If Criminal crypto-currency miner install in large enterprise networks, outweigh the costs of excessive energy consumption, degraded modes of operation, processes, downtime, and repairs machines with physical damage, and the containment of Malware in systems that may be caused to the Victims, viewed as a whole, far outweigh the relatively small amount of crypto-currency, the attacker typically earn in a single network".

The keyword cost is important, when speaking of crypto-jacking. And not only for (potential) victims, but also for the perpetrators. Because crypto-jacking is Essentially theft of electricity and CPU power. This means that it is not only widespread it will be, as long as Monero and other Coins have a value, but as long as the Mining XMR and other Kryptos is expensive.

According to the crypto compare profitability calculator for Monero, a single American Miner with a graphics card, which achieves a Hash Rate of 600 H/s (for example, the Nvidia GTX 1080) and with the use of 100W power (a very conservative estimate) each month, only 0,8033 US Dollar (EUR 0.70) profit. Of course that is not particularly promising, which is an important factor for why so many Amateurs are switching to crypto-jacking. Because mines XMR and pay for their own electricity is simply not fertile, if it is not a large Mining company.

however, There are recent signs that the Monero Mining more profitable - even for smaller Miner. This was after his Hard-Fork at the 6. April, changed his PoW Protocol, in order to make it ASIC-Miner useless. These ASIC miners dominate the Mining (in particular, in the case of Bitcoin).

Shortly after this hardware was complete Fork, there were reports in the Monero Subreddit that the profitability was increased by 300 percent or even 500 percent. This increase was lost, according to BitInfoCharts in the following weeks, however, quickly.

Monero itself, however, was just as careful in terms of the promise that it was forever against ASIC Mining equipment immune. "It is recognized that ASICs could be an inevitable development for every Proof-of-Work crypto-currency," wrote the developer dEBRYUNE and dnaleor in a blog post from February. "We concede also that ASICs may be inevitable, but we are of the opinion that any Transition to an ASIC-dominated network must be as egalitarian as possible, in order to strengthen the decentralization."


Suppose that it had become profitable, if you XMR lawfully mint. This would lead to a flattening of the growth in crypto-jacking, which was observed by some cyber security firms. In his report Q2 2018 Malwarebytes has revealed that the detections of Mining Malware from a peak of 5 million in the beginning of March to the beginning of June, fell to a low of 1.5 million. This decline may be in contradiction to what is reported by other analysts this year, but as the investigation of Malwarebytes in relation to the collected data is the most current, authoritative, probably the most.

It is unclear whether this decrease is due to an increase in profitability for the legal Monero Miner, to companies and individuals about the threat posed by crypto-jacking more and more aware of, or to a General loss of value of the crypto-currencies. Regardless of Malwarebytes predicts that crypto-currency miners will come as a cyber security threat, "out of fashion". "Of course, will continue to spread many Miner and be discovered," the report concludes. "Anyway, it looks like we're reached the end of the 'delusion'."
