Ransomware Attacks Drop while Cryptojacking Marks 4000% Increase in Q1 of 2018: Stay Safe!

Android crypto-miners have seen a staggering 4000% increase in the first three months of 2018. To put things in perspective, the total consumer detections have reached 16 million as of the end of March, according to a report issued by Malwarebytes.


It seems that last year’s cryptojacking sentiment is still running with full force, as consumer crypto-miners soar 4000% in just the first three months of 2018. Info Security cites Malwarebytes, pointing out the massive increase in Android crypto-miners.

Ransomware Attacks Decrease While Cryptojacking Booms

Malwarebytes’ Cybercrime Tactics and Techniques report for the first three months of 2018 reveals that while cryptojacking among Android consumers is soaring, ransomware detections dropped by 35% compared to the previous quarter.

Ransomware attacks have been quite popular in the crypto field and are characterized by the spread of malicious software which is known to completely block out the user’s access to valuable information. Last month we saw hackers hitting Atlanta’s local government, demanding $51,000 in bitcoin to lift the block-out.

Crypto-mining, otherwise known as ‘cryptojacking’, on the other hand, takes place when an unauthorized third party uses the capabilities of a computer or other internet-connected device for the purpose of mining cryptocurrency. And while in its essence, this form of intrusion might not be as harmful, infections could lead to very challenging repercussions. Among them, the most dangerous being system hijacking and information theft.

Other Threats to Be on the Look Out For

One would think that the massive 4000% increase in consumer crypto-mining would top off the cybercrime charts, but the truth is that adware remains the number one threat to consumers. Businesses, on the other hand, are more often the victims of spyware.

Other threats to be on the look out for

Phishing emails, prefaced to come from secured emails linking to ‘legitimate’ patches while, in reality, leading to malware, remain an underwater stone to look out for.

A fairly new trend unveils itself in the face of Coinbase-themed tech support scans. Through the usage of fake Twitter accounts as well as blackhat Search Engine Optimization (SEO) techniques, scammers lure victims into providing them with wallet credentials and other private information.

And while other treacherous schemes are also to be looked out for, these remain, by far, the most dangerous threats for the time being.

Hackers from North Korea Attempt to Steal Bitcoin

Hackers from North Korea have attempted to infiltrate several cryptocurrency exchanges in South Korea, and some entities are saying that this action should serve as a wake-up call.


One can definitely say that the country of North Korea is not a highly desirable tourist destination. The ruling military dictatorship, currently under the control of Kim Jong-un, has kept the country isolated from the rest of the world for decades. While we sometimes laugh at the absurd news that the official North Korean news agency reports, such as finding unicorns and how Kim Jong-un excels at everything humanly possible, the reality is that North Korea is a dangerous state. It has kidnapped people off the beaches of Japan and sends assassins into South Korea. It’s recent intercontinental ballistic missile (ICBM) testing has led to severe UN sanctions, and its ongoing nuclear program is definitely worrisome. Hackers from North Korea have long been active in seeking to cause mischief, and their current targets are a number of bitcoin exchanges in South Korea.

North Korea Desperately Needs Money

It should come as no surprise that North Korean hackers are looking to get their grubby mitts on some bitcoin. CNBC recently reported on this nefarious activity. A report from FireEye states that hackers from North Korea (who are extremely likely to be agents of that rogue state) have targeted the personal email accounts of those working at various bitcoin exchanges in South Korea using tax-themed lures and deploying malware. So far, three exchanges are known to have been targeted, and there is a possibility of four wallets being targeted on the Yapizon exchange as well.

North Korea is desperate for funds. The UN sanctions have really hurt their already-fragile economy as the sanctions impacted a full third of their exports (such as coal, seafood, iron ore, and iron). However, such sanctions were only the beginning as the United States has put additional sanctions upon North Korea, to which Kim Jong-un has loudly railed against. This has led to even China’s central banks cutting off ties with North Korea so as to not fall under penalty of the US sanctions. In short, North Korea is looking at any possible way to gain funds, and it appears that trying to steal bitcoin is one such method of getting needed capital.

Is This a Wake-up Call?

Of course, the news of hackers from North Korea looking to score some bitcoin has led to the usual hyperventilating from news agencies. CNBC openly wondered if these attempted thefts were a wake-up call to finally get governments and financial agencies to begin regulating digital currencies. CNBC cited University of Georgia Professor Jeffrey Dorfman, who said:

The ability of regimes like Kim Jong Un’s North Korea to mine or steal cryptocurrencies such as bitcoin is a new reason to be cautious in treating these commodities as currencies. While rogue states have practiced counterfeiting even longer than they have been computer hacking, counterfeiters are easier to catch. Once a cryptocurrency is stolen, it is virtually impossible to stop the new owner from spending it, and doing so in untraceable ways.

Are bitcoin and other digital currencies used for bad things? Of course they are. But you can say the same for gold, silver, hard currency, and so on. It’s not exactly earth-shattering to realize that bad people spend currency on bad things. However, it’s far harder to launder digital currency than the media and world governments would have you believe, as can be seen in the case in mid-July where $60 million of ether was pilfered. It would nice not to deal with all the hand-wringing whenever a bad person is associated with cryptocurrency. As for North Korea and Kim Jong-un, you can bet that they’ll continue to attempt to hack their way into different cryptocurrency exchanges. The US sanctions are not going away any time soon.
