Now, we have to understand what a coinminer is. A “coinminer” or a “cryptocurrency miner” is a program that generates Bitcoin, Monero, or any other type of cryptocurrency. Many malware authors utilize these programs to mine cryptocurrency.

The purpose of a web skimmer is to steal credit card information that users enter in the payment pages of an e-commerce website.

Webskimming attacks are also known as “Magecart attacks.” These are the attacks that steal away the credit card details the users enter on payment pages. Researchers from Palo Alto Networks have discovered that the website heureka.cz that sells many products had some malicious links in its source code. These malicious links were found to be skimming scripts.
The skimming scripts in the source code might seem as if they are leading the user to destinations that are hosted by the heureka.cz. However, these skimming scripts actually redirect the user to malicious websites.
The researchers from Palo Alto Networks advise that users have to be very cautious even while visiting well-known and apparently reputable websites. Such sites will actually generate a lot of income for those attackers who focus on web skimming and malicious coinmining.
This information from the researchers at Palo Alto has arrived at a time when online shopping is at its peak because of the pandemic. Since online shopping will be indispensable now and in the near future, it is the users’ responsibility to stay cautious and protect themselves from these malicious attacks, which prove to be worse than the Corona attack itself!
