By doing this, the attacks consume substantial power from a victim’s system without generating any revenue for the user of the device.

Why are Crypto-Malware Attacks on the Rise?

The value of cryptocurrency increases and its use grows more common cyber-attacks using crypto-malware are becoming more popular with cybercriminals. Most of the time the malware can operate without interruption and continue to run indefinitely after it is executed by the device of the user. So, attackers are able to expect a constant return on crypto-malware, as long as their code goes unnoticed.

Crypto-malware Attacks vs Ransomware Attacks

Ransomware and crypto-malware attacks are designed both to earn money for the attacker. However, the way of accomplishing this differs significantly.

The ransomware attack can encrypt the victim’s information until settlement is paid to the attacker. If no payment is completed, the attackers could then offer the data via the dark web to earn an alternative source of revenue.

Ransomware is still one of the most lucrative strategies used by cybercriminals, with the total cost of ransomware by 2020 predicted at around $20 billion, and the average ransom payout of $84,000.

Crypto-malware, on the other hand, is a silent malware that operates quietly within the background of users. Contrary to a ransomware threat that requires payment in a direct manner the criminal behind it is hoping that the malicious program is not detected until the maximum amount of time they are able to keep mining cryptocurrency with your device.

What is the Impact of a Crypto-Malware Attack?

But, its continual usage of a victim’s computing capacity to mine cryptocurrency drains the system and greatly affects the productivity that the victim.
