Security Concerns and Risks Related To Bitcoin
The popularity of cryptocurrency, a form of digital currency, is rising. However, many people do not understand cryptocurrency and the risks associated with it. Malicious cyber actors use cryptocurrency-based malware campaigns to install cryptomining software that hijacks the processing power of victim devices and systems to earn cryptocurrency. There are steps users can take to protect their internet-connected systems and devices against this illicit activity.
Cryptocurrency is a digital currency used as a medium of exchange, similar to other currencies. Bitcoin, Litecoin, Monero, Ethereum, and Ripple are just a few types of the cryptocurrencies available. Unlike other currencies, cryptocurrency operates independently of a central bank and uses encryption techniques and blockchain technology to secure and verify transactions.
Cryptocurrency mining, or cryptomining, is the way in which cryptocurrency is earned. Individuals mine cryptocurrency by using cryptomining software to solve complex mathematical problems involved in validating transactions. Each solved equation verifies a transaction and earns a reward paid out in the cryptocurrency.
Solving cryptographic calculations to mine cryptocurrency requires a massive amount of processing power. Cryptojacking occurs when malicious cyber actors effectively hijack the processing power of the victim devices and systems by exploiting vulnerabilities—in webpages, software, and operating systems—to illicitly install cryptomining software on victim devices and systems.
With the cryptomining software installed, the malicious cyber actors to earn cryptocurrency. Cryptojacking involves maliciously installed programs that are persistent or non-persistent. Non-persistent cryptojacking usually occurs only while a user is visiting a particular webpage or has an internet browser open.
Persistent cryptojacking continues to occur even after a user has stopped visiting the source that originally caused their system to perform mining activity. Malicious actors distribute cryptojacking malware through weaponized mobile applications, botnets, and social media platforms by exploiting flaws in applications and servers and by hijacking Wi-Fi hotspots.
Any internet-connected device with a CPU is susceptible to cryptojacking. The following are commonly targeted devices:. The following cybersecurity best practices can help you protect your internet-connected systems and devices against cryptojacking:.
This product is provided subject to these Terms of Use and this Privacy Policy. View Previous Tips. Original release date: February 01, What is cryptocurrency? What is cryptomining? What is cryptojacking? Cryptojacking may have the following consequences to victim devices, systems, and networks: Degraded system and network performance because bandwidth and central processing unit CPU resources are monopolized by cryptomining activity Increased power consumption, system crashes, and physical damage from component failure due to the extreme temperatures Disruption of regular operations Financial loss due to system downtime caused by component failure and the cost of restoring systems and files to full operation as well as the cost of the increased power consumption Cryptojacking involves maliciously installed programs that are persistent or non-persistent.
What types of systems and devices are at risk for cryptojacking? The following are commonly targeted devices: Computer systems and network devices — including those connected to information technology and industrial control system networks; Mobile devices — devices are subject to the same vulnerabilities as computers; and Internet of Things devices — internet-enabled devices e.
How do you defend against cryptojacking? The following cybersecurity best practices can help you protect your internet-connected systems and devices against cryptojacking: Use and maintain antivirus software. Antivirus software recognizes and protects a computer against malware, allowing the owner or operator to detect and remove a potentially unwanted program before it can do any damage. See Protecting Against Malicious Code. Keep software and operating systems up to date. Install software updates so that attackers cannot take advantage of known problems or vulnerabilities.
See Understanding Patches and Software Updates. Use strong passwords. Select passwords that will be difficult for attackers to guess, and use different passwords for different programs and devices.
It is best to use long, strong passphrases or passwords that consist of at least 16 characters. See Choosing and Protecting Passwords. Change default usernames and passwords.
Default usernames and passwords are readily available to malicious actors. Change default passwords, as soon as possible, to sufficiently strong and unique passwords. Check system privilege policies. Review user accounts and verify that users with administrative rights have a need for those privileges. Restrict general user accounts from performing administrative functions.
Apply application allow listing. Consider using application allow lists to prevent unknown executables from launching autonomously. Be wary of downloading files from websites. Avoid downloading files from untrusted websites.
Look for an authentic website certificate when downloading files from a secure site. See Understanding Website Certificates. Recognize normal CPU activity and monitor for abnormal activity. Network administrators should continuously monitor systems and educate their employees to recognize any above-normal sustained CPU activity on computer workstations, mobile devices, and network servers.
Investigate noticeable degradation in processing speed. Disable unnecessary services. Review all running services and disable those that are unnecessary for operations.
Disabling or blocking some services may create problems by obstructing access to files, data, or devices. Uninstall unused software. Review installed software applications and remove those not needed for operations. Many retail computer systems with pre-loaded operating systems come with toolbars, games, and adware installed, all of which can use excessive disk space and memory.
These unnecessary applications can provide avenues for attackers to exploit a system. Validate input. Perform input validation on internet-facing web server and web applications to mitigate injection attacks.
On web browsers, disable JavaScript execution. For Microsoft Internet Explorer, enable the cross-site scripting filter. Install a firewall. Firewalls may be able to prevent some types of attack vectors by blocking malicious traffic before it can enter a computer system, and by restricting unnecessary outbound communications.
Some device operating systems include a firewall. Create and monitor block lists. Monitor industry reports of websites that are hosting, distributing, and being used for, malware command and control. Block the internet protocol addresses of known malicious sites to prevent devices from being able to access them. Authors CISA.

Bitcoin Uses More Electricity Than Many Countries. How Is That Possible?
Cybercriminals have started using crypto mining software to infect enterprise infrastructure. They are using cryptojacking to have a fixed, reliable, and constant income stream and are very clever in hiding their malware. Cryptojacking is hidden and secretive and is harder for enterprises to detect it. They are working hard to find any sign of critical data being encrypted in a ransomware attack. If the crypto jacking infects the cloud infrastructure or electric bills than it may impact the finance immediately. It can also reduce productivity and performance once it enters the machine. If your CPU is not specifically made for crypto mining then it will cause damage to the entire hardware or may slow down its speed.
