Crypto mining on the rise among hackers
Organizations of all sizes have made considerable shifts to using cloud-based infrastructure for their day-to-day business operations. However, cloud security hasn't always kept up with cloud adoption, and that leaves security gaps that hackers are more than happy to take advantage of.
One of the most widely observed objectives of attacking an organization's cloud infrastructure has been for cryptocurrency mining. Despite recent falls in cryptocurrency prices, mining campaigns continue to plague organizations. We've seen attackers using open APIs and unauthenticated management interfaces to compromise container management platforms. We recently investigated attacks involving mining malware served from the domain xaxaxa[.
That domain may sound familiar, as it appeared in a February report by RedLock on the compromise of the Kubernetes infrastructure of an electric car company. The report details the container commands showing the malicious request. RedLock reported the attackers used the compromised Kubernetes server in Amazon Web Services to mine Monero and potentially access customer data.
In the event of such unrestricted access, cryptocurrency mining is one of the least malicious outcomes to victim organizations. For example, customer data and business operations could be at risk for theft or malicious modification. Following the attention of the report by RedLock, the owners of xaxaxa[. Notably, we have also observed the domain serving pages saying it is a Dynamic Domain and a Vesta Control Panel.
However, we have seen from other attacks listed in this article that the root domain is actively involved in serving malware and implicated in other campaigns.
We have also observed attacks aimed at the control panels of web hosting solutions. The impact is similar to the previous topics, essentially allowing administrative control over web services for the execution of malicious code. In April , the same attackers that compromised Kubernetes infrastructure started exploiting an unknown vulnerability in VestaCP.
VestaCP users provided details on how their installations were compromised. Lastly, the attackers set the following script to run in Cron, ensuring mining persistence after quick attempts at removal.
One of particular severity was a compromise of the official source-code which resulted in the administrative username and passwords of new installations being sent to attackers. Perhaps the best known method of compromising cloud computing is through the theft of API keys. There are many attackers who automatically scan the web and various public tools such as GitHub for API keys which are unknowingly publicly accessible.
As some have experienced , the attackers work fast and can greatly impact business operations. Another avenue of attack is to run malicious Docker containers.
This approach generally relies on individuals across the world who use prebuilt Docker images and in an effort to save time, download images with containers operating a mining service. This mining service is unknown to the user and will continue generating income for the malicious owner.
There have been reports of Docker images known to be abused in Monero mining schemes on Dockerhub, the official container repository. The images originally reported on have since been removed, but we continue to encounter other malicious containers such as those from the Luoxk mining botnet that remain on DockerHub.
There have been a relatively small number of users who have reported running these malicious containers.
However, some may still be found on Reddit on compromise by Luoxk. The screenshots are from our USM Anywhere platform, however a similar approach should be possible in other threat detection and response tools.
You can also detect crypto mining generically on hosts by looking for command line parameters that resemble those of common crypto-mining tools such as xmrig.
For server-side attacks that lead to instances compromised for mining, we normally see exploits executed over the network. You can look for both of these suspicious behaviours. You can also generically look for Docker containers spinning up with suspicious commands containing keywords associated with crypto-mining. The malicious activity is often specific to cloud environments.
For example, when an attacker steals a credential for AWS, they will normally start deleting instances and spinning up new instances to mine cryptocurrency.

Hackers target smartphones to mine cryptocurrencies
With the establishment of cryptocurrency, the era of a new means of payment has been ushered Crypto Mining in. We started with Bitcoin, which was first described in by the Japanese Satoshi Nakamoto in the Bitcoin white paper. His idea: The establishment of a digital currency. This should be organized decentrally, i. The maximum number of Bitcoins should be limited to a total of 21 million, in order to exclude inflation from the outset.
Hackers are mining for Bitcoin, and they might be using your computer
Learn about our people, get the latest news, and much more. When it comes to keeping up with cybersecurity , the pace is even faster. Here are some facts and trivia tidbits about cybersecurity to inspire you to learn more about cybersecurity and the education it takes it be one of those who keep people on the internet safe. Bitcoin is a digital currency that can be transferred from one person to another without the use of a bank. You might have heard about bitcoin because of the WannaCry ransomware. Victims would load their computers to find a screen telling them their files have been encrypted and would only be released if they sent the hackers a certain amount of money in bitcoin. Hackers like to use bitcoin because of its anonymity. But hackers, ethical ones, can be hired to do just that for a company who needs their security measures tested. A company might hire an ethical hacker to attempt to break into their system and, in the process, expose vulnerabilities that the bad hackers might exploit. An ethical hacker helps a company become safer.
Cryptocurrency miners hijack NHS computers to create bitcoin-style money using malware
Cryptomining, or cryptocurrency mining, is the process of using your computer's processing power to solve complex mathematical equations to earn digital cash. The "crypto" in cryptomining is short for cryptography, which refers to the code that needs to be solved to earn digital currency. Once the problem is solved, it is added to a public list of transactions called the blockchain. In exchange for doing this, people are rewarded with cryptocurrency- hence the term cryptocurrency mining.

Cryptojacking: How Hackers Steal Resources to Mine Digital Gold
Cryptocurrency and crime describes notable examples of cybercrime related to theft or the otherwise illegal acquisition of cryptocurrencies and some of the methods or security vulnerabilities commonly exploited. Cryptojacking is a form of cybercrime specific to cryptocurrencies that has been used on websites to hijack a victim's resources and use them for hashing and mining cryptocurrencies. According to blockchain analysis company Chainalysis, illicit activities like cybercrime, money laundering and terrorism financing made up only 0. There are various types of cryptocurrency wallets available, with different layers of security, including devices, software for different operating systems or browsers, and offline wallets. Novel exploits unique to blockchain transactions exist which aim to create unintended outcomes for those on the other end of a transaction. One of the more well known issues that opens the possibility for exploits on Bitcoin is the transaction malleability problem.
Cyberhackers are using compromised cloud accounts to mine cryptocurrency, Google has warned. Blockchain is a digital ledger that provides a secure way of making and recording transactions, agreements and contracts. However, uniquely, rather than being kept in one place like the more traditional ledger book, the database is shared across a network of computers.

Instead, they gain access to enterprise network files and data, exploit employees through social engineering and scams, steal identities, and carry out cyber-extortion schemes. They also deploy ransomware to lock corporate systems and data and then demand hefty ransoms from their victims. Digital currencies help enable many such cybercrimes, especially ransomware attacks. Like standard fiat currencies, they can be used to purchase goods and services. Cryptocurrencies rely on cryptography to secure and verify transactions, manage the creation of new units, and prevent counterfeiting—all well and good.
Cryptocurrency miners are using compromised Google Cloud accounts for computationally-intensive mining purposes, Google has warned. The search giant's cybersecurity team provided details in a report published Wednesday. The so-called "Threat Horizons" report aims to provide intelligence that allows organizations to keep their cloud environments secure. Cryptocurrency mining is a for-profit activity that often requires large amounts of computing power, which Google Cloud customers can access at a cost.
It's impossible.
