CrazyCoin

CrazyCoin Description

The CrazyCoin threat is a brand-new miner that is a rather complex and well-developed tool that utilizes various tricks and techniques. It would appear that the threat is exploiting vulnerabilities that became known publicly after the NSA leak known as Eternal Blue.

The DoublePulsar utility, which is a hacking tool used by the NSA (but became known after the infamous leak), serves as a backdoor for the threat to get access to the targeted system. Upon compromising the targeted machine, the CrazyCoin malware will connect to its operators' C&C (Command & Control) server. Next, the threat will fetch the payloads of the miner module, as well as the infostealing module. The CrazyCoin threat would use the stealer module to collect data from the infected system.

With hackers getting more brazen and cunning each day, it was only a matter of time before a threat like CrazyCoin emerged. CrazyCoin is a kind of worm trojan horse that combines elements of hacking with mining and backdoor access to computers. The virus spreads through the Eternal Blue leak of the NSA. Once it infects a computer, CrazyCoin downloads mining and data-stealing modules. CrazyCoin also implants the double pulsar backdoor program on computers. The three separate modules of the virus work with each other to perform their duties and cause all kinds of havoc for computer owners.

Mines for Monero and Handshake Cryptocurrencies

The CrazyCoin malware would use Powershell scripts to obtain the mining module, which will then be planted on the compromised computer. The attackers are using a modified version of XMRig, a legitimate cryptocurrency mining application that is used by millions of users worldwide. However, their version has been stripped off of some of the unnecessary features, and the barebone variant of the XMRig tool is used to launch a silent cryptocurrency mining operation on the compromised PC. This utility is used for the mining of the Monero cryptocurrency. All the mined coins are transferred to the wallet of the CrazyCoin threat operator automatically. The CrazyCoin malware also would deploy a second cryptocurrency miner – NBMiner. The NBMiner application is a genuine tool, just like the XMRig miner, that countless users utilize for mining the HNS (Handshake) cryptocurrency.

Collects Data

The CrazyCoin malware also is likely to deploy an 'http' service, which operates as a lightweight search utility. The threat will utilize this tool to search for important data like cryptocurrency wallets, ID cards, login credentials, etc. The CrazyCoin threat utilizes port 3611 as a means of detecting relevant information. If any data that fits the criteria is detected, the CrazyCoin malware will make sure to collect it and transfer it to the C&C server of the attackers. This threat is capable of spreading laterally through the intranet connected to the compromised PC.

Gains Persistence

The CrazyCoin malware will make sure to gain persistence on the infected computer. The threat does that by creating a new Windows service that is meant to execute the payload whenever Windows starts. The threat also does periodic checks to ensure that the threatening program is running as intended. If any of the processes get interrupted, the CrazyCoin malware is capable of executing them again so that the operation does not come to a halt.

The CrazyCoin malware is a threat that is capable not only of using up your system's computing power and therefore reducing its lifespan but also collecting your cryptocurrency wallets alongside other files. Make sure your system is protected by downloading and installing a reputable anti-virus solution.

Like any other kind of virus, CrazyCoin is the product of cybercriminals. They create viruses like this to make an illegal profit and cheat innocent computer users. Threat actors never show any kind of mercy to their victims. CrazyCoin performs all manner of malicious code that sap the CPU and GPU power of a computer and prevent it from working correctly.

There are several signs a virus has infected a computer. You might see fake security alerts or notifications. These notifications ask you to download new security applications to boost performance and secure your computer. Those alerts are all fake, and the software you download will just infect your computer more. These alerts are not to be trusted. Even if there are no software downloads, just connecting can give away your IP address or other sensitive information.

If you are at all concerned about the health of your computer and potential for viral infection, be sure to run antivirus software. Antivirus software detects problems like CrazyCoin and takes steps to remove them before they can do irreparable damage.

How Does CrazyCoin Spread?

Like a trojan horse virus, CrazyCoin infects computers through spam emails, fake email attachments, and as part of free software bundles downloaded from the internet. Scammers and hackers regularly send out spam email campaigns filled with malicious attachments. The emails have a message that makes them appear somewhat legitimate to create curiosity and give readers a false sense of security.

Be on the alert for emails that contain Office, RAR, Javascript, PDF, and EXE attachments. These attachments are more likely to be a virus, especially if the email comes from an unknown source, and the email was unsolicited. In general, you should be careful when opening any email attachment at all from an unknown source. Have your antivirus program scan it first before downloading and accessing it.

How to Protect Against CrazyCoin

There are several things you can do to protect yourself and your computer against infections like CrazyCoin. Here are some of the best practices to avoid infection;

  • Have an antivirus program that offers real-time protection
  • Be sure to have your firewall activated at all times
  • Conduct regular scans of external devices such as USB devices, hard drives, and memory cards
  • Keep applications and programs updated with updates from the official source
  • Avoid using shareware and freeware when possible to prevent viruses infecting your computer
  • Never open spam emails, even ones that appear legitimate, if they have an attachment and are from an unknown source
  • Keep regular backups of data to prevent data loss
