A new form of malware – kryptojacking – is gradually crawling from a narrow to the mainstream. As the use of cryptographic currencies increases, malware is becoming a threat to both individuals and businesses. Know how to detect a cryptographic attack.
But what is kryptojacking? What makes it so difficult to detect and prevent it? Define, but first better understand what it means.
Kryptojacking is a cybercrime tactic that uses victim machines to dig into cryptographic currencies without their consent. While they don’t usually steal information about a violation, they slow down the machine and drain the battery.
How to identify a kryptojacking attack
The Cryptojacking script is difficult to identify as an unusual malware. A few signs indicate that your device may have received a malicious script.
The first rule: not all of your device’s antivirus tools and scanning software will count on your efforts to detect the cryptographic code. This is because many of these scripts are fully legitimate, making them unrecognizable by signature-based cybersecurity software.
You need to be vigilant in your systems to find out if they are working harder than usual. Mining is an activity that costs a computer a processor. If it overheats, it may be a sign of infection. If you’re a company that runs a business, the number of employee complaints about the performance of their machines may suddenly increase, or your data may indicate an increase in CPU waste.
Blocking from kryptojacking
There is nothing special about preventing cryptography. Rather, only caution to prevent more traditional cybercrime will protect you.
Training against phishing-type attacks
Phishing has been used to steal important user information such as credit card number and login information. An attacker would disguise himself as a trusted resource and trick the victim into opening a mail or text message with a malicious link, leading to the installation of malware. You need to train your staff on the dangers of phishing-type attacks. If they feel the start of such an attack, they are better able to guess.
Improving browser security
A good portion of cryptographic attacks are run by users’ web browsers. Increasing the security of your browser reduces the chances of an attacker gaining a breakthrough. Get a browser with a built-in security layer that absorbs such scripts with effective ad blocking. Using high-quality VPNS also improves browser security. There are add-ons that can block such malicious scripts effectively.
Check personal devices
If your staff works on their own devices, use device management software to manage related installations. You must also keep the software up to date. Encourage employees to use secure browsers and applications, as this provides the first level of security.
Use anti-encryption plug-ins
You can install browser extensions to prevent cryptographic extraction scripts. Plug-ins like Anti Miner, minerBlock, and No Coin are known to prevent such scripts from entering your device.
Keep tabs on cryptographic trends
Like all aspects of the technology, the encryption method code evolves. Therefore, it is absolutely essential to monitor kryptojacking trends to understand how the behavior of malicious scripts changes. Understanding the distribution mechanisms of such code will keep such threats under control. In December 2020, a botnet was identified, which added the address of the Bitcoin wallet and the URL of the API checking the wallet to the malicious code. The researchers concluded that the code used this information to calculate the IP address and move to infect more devices.
Configure the network monitoring solution
Kryptojacking is more likely to be detected in business buildings than in homes because companies typically implement network monitoring. On the other hand, consumer endpoints lack such systems. However, it is important to ensure that the network monitor tool deployed has the ability to analyze suspicious scripts for accurate detection. An advanced artificial intelligence solution can have the ability to analyze available data and combat potential threats.
Underestimating the harmful consequences of cryptographic attacks is a self-defeating mistake. Take it as a case where an attacker invades your security and pay close attention to a complete review of it. You can also board a company to monitor your safety equipment and make recommendations. Expert help is sure to take your ecosystem to the level of cybersecurity.
