Cryptojacking is a type of cyber attack that involves stealing computing power from a victim’s computer to mine cryptocurrencies. This technique is often used by hackers and other malicious actors to generate revenue without the knowledge or consent of the victim.
Definition of Cryptojacking
Cryptojacking is a form of malware that secretly uses a victim’s computer processing power to mine cryptocurrencies. The term was first coined by security researcher Eyal Oshani in 2013, and since then, it has become an increasingly common method for hackers to generate revenue without the knowledge or consent of the victim. Cryptojacking can be performed through various means, such as browser extensions, malicious software, and even social engineering tactics.
How does Cryptojacking work?
Cryptojacking works by exploiting vulnerabilities in a victim’s computer or network to gain access to their processing power. Once the attacker has obtained this valuable resource, they can use it to mine cryptocurrencies, which involves solving complex mathematical equations to validate transactions and add new blocks to the blockchain.
The process of mining cryptocurrencies requires significant computational power, which is why attackers often target computers with powerful processors and graphics cards. By stealing this processing power, attackers can generate revenue by mining cryptocurrencies, without the knowledge or consent of the victim.
The impact of Cryptojacking
Cryptojacking can have a significant impact on both individuals and organizations. For individuals, cryptojacking can lead to slow performance of their computer or even cause it to crash, as well as increased electricity bills due to the additional processing power being used. In addition, cryptojacking can also put sensitive personal information at risk if the attacker gains access to the victim’s computer or network.
For organizations, cryptojacking can be particularly damaging, as it can lead to significant financial losses and reputational damage. In addition, cryptojacking can also put sensitive business data at risk, as well as compromise the integrity of the organization’s networks and systems.
Protecting against Cryptojacking
There are several steps that individuals and organizations can take to protect themselves from cryptojacking attacks. One of the most important is to use reputable antivirus software and to keep it up-to-date. This will help detect and remove any malicious software that may be installed on your computer or network.
Another effective method for protecting against cryptojacking is to be cautious when clicking on links or downloading attachments from unknown sources. Malicious actors often use social engineering tactics, such as phishing emails, to trick victims into installing malware or browser extensions that are used to steal processing power.
In addition, it is important to regularly update your computer’s operating system and software to ensure that any known vulnerabilities are patched. This will help prevent attackers from exploiting these vulnerabilities to gain access to your computing power.
Real-life examples of Cryptojacking
Cryptojacking attacks have become increasingly common in recent years, with many high-profile cases making headlines. One such case occurred in 2018, when a cryptojacking malware was discovered that infected millions of computers around the world. The malware, known as WannaCry, used the victim’s processing power to mine the Monero cryptocurrency, generating significant revenue for the attackers.
Another example of cryptojacking occurred in 2017, when a group of hackers used a browser extension to steal processing power from over 8 million computers around the world. The group, known as the Electrocoiners, generated over $3 million in revenue from mining the Monero cryptocurrency, without the knowledge or consent of the victims.
