What Is Cryptojacking and How to Detect It

This article is brought to you by 1xBit – the N°1 crypto betting & gambling platform

Cryptocurrency appeared in 2009 with the launch of Bitcoin, created by Satoshi Nakamoto (an anonymous group or person). This digital cash system uses a technology called blockchain, that stores transaction data accurately and transparently, which can be publicly accessed by anyone.

All cryptocurrencies that exist today use a variation of blockchain technology. Blockchain is a chain of blocks that timestamp the transactions in order to prevent double-recording or backdating. Each block records transaction data, such as the receiver, sender, the number of coins transferred, and a cryptographic hash.

Each new transaction is sent over the network, and after the miners verify and prove its validity, it is then added to a new block permanently, and no modifications can be brought to the recorded information of the block ever again.

To get new cryptocurrencies some people use mining, but as it is a very resource- and time-intensive process, some have found a way of illegally making crypto.

Cryptojacking is a type of cyber-attack that involves using the computing resources of unknowing victims with that mine coins for the hacker.

It is worth mentioning that cryptojacking has become a popular option for hackers of getting free crypto, as it is pretty hard to detect and not as punishable like other cybercrimes.

The Process of Cryptojacking

The process involves using cryptojacking software that makes the victims’ computers mine new cryptocurrencies from various blockchains. While the new crypto generated is deposited into the hacker’s wallet address, the costs of mining – electricity and computational power – is supported by the victim. All Internet-connected devices can get infected, not only computers.

Sicherheit, Schutz, Antivirus, Software, Cms, WordPress

Back in September of 2017, the Coinhive organization published on their website, a mining tool for website owners to passively earn crypto. But cybercriminals used this code in their cryptomining scripts to hijack users’ computers.

After creating the script, the next thing they had to do was to infect computers with it. The most common way of spreading is malware.

Another common method involves deceiving users into downloading the cryptojacking script and passing it off as another software, or hiding it along with other software so it can get installed unnoticed.

With legitimate browser-based cryptomining, the owner of the site has to alert the visitor of the script, and only with the visitor’s consent can the site use his computational resources. Shadier sites do not ask for any consent and use their site visitors’ resources to mine crypto for them.

So, are there any ways in which you can detect if your devices have been cryptojacked?

How to Find Out if You Have Been Cryptojacked

Check if you have a decrease in performance

Slower performance is usually the first sign of cryptojacking, so you should check if there has been a decrease in processing.

Overheating

As crypto-mining is resource-intensive, check if your system is overheating more often, as cryptojacking can damage the computer long-term.

Check CPU usage

Monitor and analyze the central processing unit (CPU) usage, either by accessing the Activity Monitor or Task Manager. If you notice a spike in CPU usage when you are on websites with little or no media content, it can indicate the presence of cryptomining scripts.

Perform malware scans

Scan for malware using your security software to find these malicious scripts or files and avoid installing them once detected.

How to Prevent Cryptojacking

Educate yourself

Teach yourself to understand and spot the first signs of cryptojacking when browsing online, such as not clicking on links in emails or downloading from shady sources.

Use anti-cryptomining extensions

There are several browser extensions that can block cryptominers from web browsers, such as minerBlock, No Coin, and Anti Miner.

Use ad-blockers

An ad-blocker can detect and block cryptomining scripts which are frequently embedded in web ads.

Disable JavaScript

Disabling JavaScript can prevent your computer from getting infected with malware while you are browsing online.

Monitor sites

Frequently track your own websites to prevent any pages from being compromised by cryptojacking.

In order to avoid cryptojacking, users should only access sites that have guarantee anonymity, security, and reliable bet processing, such as the 1xBit online casino & sportsbook.
