Cryptojacking has been an infamous way of online fraud by hackers, the unauthorised way of practising crypto mining using a victim’s processing power has now been exposed in front of traders. Now it has the potential to shake your entire system and could bankrupt you. In our previous blog we have discussed the WannaMine attack that badly affected the mining of Monero, a very popular cryptocurrency.
Whereas real crypto mining is all about verification and valid transaction report, a miner has to do a validity check of the transaction made and after the mining process of a block is publicly broadcasted, the miner gets a reward. However, this process has a long cycle of verification and validation, also it is not that easy to find a block, it requires more rounds of process and is time-consuming, requires more electricity and hash power.

Serious security breaches
Cryptojacking offers a quick solution to hackers, simply hack the system of the miner or the crypto trader, get access to his information and files, steal his login-id and password and then execute your infected code, running continuously and damaging your entire system!
Following are some of the methods which are being followed by hackers:
These methods are used by hackers to crack down on your security system and steal your information
- Compromising high-powered computer system with abundant CPU resource
Hackers made a target to those devices which have vulnerable operating systems and have some flaws in their configuration
- They will look for the system which has weak passwords and security systems.
- After infecting the system, the system will be operated on their command and will supply them with an enormous amount of mining resources.
- If left unnoticed, then it will exhaust your entire mining resource and would be able to make a large profit from it.
- Sometimes they compromise multiple servers which have weak passwords and are the system of an organisation, in this case, they would try to infect the entire server-networks of the organisation.
2. Local drive corruption
This type of infection occurs when we are using a local drive to download some compromised downloading item, these downloads are themselves the infected carriers that invade your system secretly.
- Getting connected to illegal sites and initiating the download from an unverified site.
- This site may contain malicious files or setup which gets downloaded along with the other items.
- After the downloading process, it will automatically execute itself and will work behind the background with a secret invasion.
- This malicious software would start mining for the hackers and would continue its mining process until discovered by the user or is completely removed from the system.
- Sometimes the anti-crypto mining extensions would be able to identify the infection, but in most cases, it will not be able to be identified so easily.
3. Javascript infection
This type of infection would require the use of JavaScript for its execution, the bad actors (Hackers) may compromise the site or would change the JavaScript to some extent and it will then run along with your coding system.
- These Javascript infections may get into your computer through visiting a website, reading an online article, playing online computer games or downloading any item.
There are many ways through which Javascript is executed into your system
- Now, this JavaScript is purposely fed into the systems by the hackers which contain an illegal crypto mining script inside it, they installed it because of earning money and online cash from the visitors.
- This concept is simple as placing online ads, if your blog or site is optimized for the monetization process, every time a visitor will be paying a visit to your blog or will click the ad you earn money.
- But if you get no notification or message regarding the no of visits made on your blog, then it’s the complete sign that your system has been cryptojacked!
Final thoughts
Some various ways and methods are smartly executed and planned by these so-called bad actors, who install the program or code into your system and then it will infect your system, run without your consent, and transfer the entire profit and money into their digital wallets.
