Where there is money, there is a thief, which is no different regarding cryptocurrency. Have you ever noticed your computer suddenly heating up and whirring like it’s about to take off? Or maybe you’ve had a sudden urge to become a cryptocurrency miner overnight? If so, you might have fallen victim to the latest tech trend: crypto malware. 

This sneaky malware takes over your computer to mine cryptocurrencies or holds your files for ransom. It’s like the digital equivalent of a parasitic roommate who uses all your electricity and never pays rent. This blog will explain the dark side of the Cryptocurrency- Crypto Malware.

What is Crypto Malware

What is crypto malware? 

Crypto malware, malicious cryptocurrency software, is a malware designed to exploit cryptocurrencies for financial gain. This type of malware can take on several forms, such as crypto-jacking, which involves secretly using a victim’s computer to mine cryptocurrencies.

It also includes ransomware, which demands payments to restore access to data or systems. Crypto malware can infect a computer or network through various methods, such as phishing emails, malicious downloads, or exploiting vulnerabilities in software. 

Once installed, it can run in the background without the user’s knowledge, using the computer’s resources to mine cryptocurrencies or encrypt files. Crypto malware can be highly lucrative for cybercriminals and cause victims significant financial harm.

What are some different types of crypto malware?

There are several types of crypto-malware, including:


This malware encrypts the files and demands payment for the decryption key. The ransom is usually required in cryptocurrency, making it difficult to trace.


Cryptojacking involves using the victim’s computer to mine cryptocurrency without their knowledge or consent. The malware secretly runs in the background, using the computer’s resources to mine the cryptocurrency and send it to the attacker’s wallet.

Fake wallets and exchanges 

These fraudulent websites or software appear to be legitimate cryptocurrency wallets or exchanges. When users enter their login credentials or deposit funds, the attackers steal the information or funds.

Malicious mobile apps

These apps appear legitimate but contain malware that can steal cryptocurrency or other sensitive information from the user’s device.

Clipboard hijackers

These malware programs monitor the user’s clipboard for cryptocurrency wallet addresses. When the user copies a wallet address, the malware replaces it with the attacker’s address, causing the victim to send cryptocurrency to the attacker’s wallet instead.

It’s essential to be aware of these different types of crypto-malware and take specific steps to prevent infection, such as using reputable anti-malware software and being cautious about opening suspicious emails or downloading unknown software.

What signs are that a computer or network is infected with crypto malware?

The signs that a computer or network is infected with crypto-malware may vary depending on the specific type of malware, but here are some general indicators to look out for:

Slow performance

Crypto malware, especially crypto-jacking malware, can use many computer resources, resulting in slower performance.

Unusual network activity

If a computer or network is infected with crypto-malware, there may be unusual network activity, such as increased data usage or network traffic.

Pop-up messages or demands for payment

Ransomware may display pop-up messages demanding payment in exchange for the decryption key.

Unexpected changes in files or programs

Ransomware may change file extensions or add a new extension to encrypted files. Cryptojacking malware may install new programs or browser extensions without the user’s knowledge or consent.

High CPU usage

Cryptojacking malware can cause CPU usage to spike, even when the computer is idle.

Suspicious outgoing network traffic

Cryptojacking malware may send outgoing network traffic to the attacker’s server, which network monitoring tools can detect.

If you notice any of these signs, you must take immediate action to investigate and remove the malware to prevent further damage.

How to prevent crypto-malware from infecting computers or networks

Prevention is also better than cure; here are some ways to protect crypto-malware from infecting your computer. 

Use a reputable anti-malware software

Install and regularly update reputable anti-malware software to detect and remove any malware infections.

Keep your software updated

Regularly update your operating system and software applications to patch any vulnerabilities cybercriminals may exploit.

Use strong and unique passwords

Use strong, complex passwords unique to each account and change them regularly.

Be wary about unknown emails and attachments

Be careful about opening emails and downloading attachments from unknown or suspicious sources, as they may contain malware.

Use two-factor authentication

Use two-factor authentication to add an extra layer of security to your accounts.

Backup important data

Regularly backup important data to an external hard drive or cloud-based storage to avoid data loss in case of a malware attack.

Educate yourself and your employees

Educate yourself and your employees on recognizing and avoiding phishing attacks and other social engineering tactics cybercriminals use.

Implementing these preventive measures can reduce the risk of your computer or network becoming infected with crypto-malware.
