Cryptojacking (2024)

FAQs

What is cryptojacking in simple terms? ›

Cryptojacking is a type of cybercrime that involves the unauthorized use of people's devices (computers, smartphones, tablets, or even servers) by cybercriminals to mine for cryptocurrency.

Distinguishing Legitimate Mining from Cryptojacking

The former is a legal and intentional process where individuals or companies use their resources to mine cryptocurrencies. In contrast, cryptojacking is inherently non-consensual and illegal.

Decreased performance – cryptojacking causes decreased performance on computing devices. You should watch out for slower system performance, as well as devices that run slowly, crash, or exhibit unusually poor performance. Another indicator is a battery that drains more quickly than it usually would.

For example, the Romanian hacker group Outlaw compromises Linux servers and Internet of Things (IoT) devices by using default or stolen credentials and exploiting known vulnerabilities to launch DDoS attacks or mine Monero currency.

Considering this, cryptojacking is a way for criminals to cut costs while increasing their potential for financial gain. That's part of why it's growing in popularity, with 332 million cryptojacking attacks tallied in the first half of 2023, a record 399 percent increase from 2022.

Cryptojacking is when threat actors use stolen cloud resources to avoid paying for the necessary servers and power, the cost of which typically outweighs the profits. Cryptojackers make $1 for every $53 their victim is billed.

Bitcoin addresses themselves don't directly reveal personal information. However, if the police can connect a Bitcoin address to a real-world identity (e.g., through an exchange, a service provider, or investigative work), they can potentially trace the wallet to its owner.

Cryptocurrency crimes are criminal acts that involve cryptocurrency in some way. While there aren't many crypto-specific laws on the books, how cryptocurrency is used can lead to federal criminal charges if one is not careful.

BitCoinMiner is Malwarebytes' generic detection name for crypto-currency miners that may be active on a system without user consent.

Cryptocurrencies are harder to mine now due to increased competition and the design of many blockchain networks. As more miners join the network, the difficulty level adjusts to ensure that blocks are mined at a consistent rate. This adjustment makes it progressively challenging to mine new blocks.

What is the most difficult crypto to mine? ›

Bitcoin is often considered one of the most challenging to mine due to its proof-of-work consensus algorithm and the high computational power required. Other coins may have different difficulties based on their unique protocols and algorithms.

There are four main types of mining: Surface, underground, placer, and solution mining. Each method has advantages and limitations that must be considered before determining which one is best suited for a particular project.

Miners must solve the hash puzzle by finding the hash below a given target through the difficulty requirement. The target, stored in the header, is expressed as a 67-digit number that will determine the mining difficulty based on the number of miners competing to solve a hash function.

The mining industry has identified several ways to build sustainability into mining. Implementing sustainable practices: Tailing reuses extracted residual metals from previous mining projects, minimizing waste and impact. Additionally, ensuring waste is managed safely and efficiently can prevent disasters.

Crypto Solution allows banks and digital wallets to offer their own customers the possibility to buy, sell, receive, send and store Bitcoin, Ethereum, stablecoins and many other cryptocurrencies using their own mobile banking apps.
