How To Tell If Your Device Is Affected By Cryptojacking?

As a form of cybercrime, “cryptojacking” includes the illegal use of victims’ equipment (personal computers, mobile phones, tablets, and even servers) to “mine” for bitcoin or other cryptocurrencies. A victim’s computer may be infected with cryptojacking software via phishing, code download from fraudulent websites, or other malicious techniques. Cryptojacking can also occur via code embedded in digital advertizements or web pages that are only activated when the victim visits a particular website.

Why should you be worried about hackers cryptojacking your devices?

A sluggish computer and a larger electricity bill are classic indicators of cryptojacking attacks on a personal laptop used at home. Targeted crypto mining on a massive scale might cause severe damage to a business. System failures and downtime impair sales and corporate productivity and transform expensive, high-performance servers into costly, low-performance servers. As computational resources are diverted from their intended use to suit the needs of cryptocurrency miners, operational costs inevitably increase. Furthermore, the presence of cryptocurrency mining software on the network is indicative of more serious cybersecurity concern.

How to tell if your devices have been Cryptojacked?

The objective of cryptojacking is to mine more cryptocurrency while going undetected for as long as possible. Cryptojacking malware is made to utilize as much power as it requires while remaining undetected. There are several indicators that cryptojacking malware has been installed on your computer. Some of these are:

  • Slower working of devices

The efficiency of computing devices is lowered by cryptojacking. Be wary of gadgets that operate slowly, crash, or have particularly poor performance. You should also pay attention to decreased system performance. Batteries that deplete more quickly than they normally would are another sign.

  • Increase in heat dissipation by the processor and CPU fan

If your computer gets too hot, which might be the result of a cryptojacking website or software, the fan will speed up to cool things down. A cryptojacking script may be present on a website or computer if the user notices that their device is overheating and the CPU fan is constantly operating at a greater speed.

  • Heavy utilization of CPU or computational resources

If your CPU usage goes up when you visit a site with few or no media files, this could be a sign that cryptojacking scripts are running. You can test for cryptojacking by keeping an eye on how much the CPU is being used. You can use the Activity Monitor or Task Manager to check this.

  • Quicker battery discharge

Due to an increase in CPU utilization and fan speed, the power consumption of devices and computing systems increases dramatically. This causes the battery to deplete faster. Therefore, if you observe that the device’s battery is draining quickly, this could be a symptom of cryptojacking

  • Increased electricity costs due to cryptojacking

An increase in power consumption by the infected devices leads to higher electricity usage. An unexpected spike in electric power consumption can also be a possible indicator of devices being infected by cryptojacking malware

Application Security Tips

With ever-growing challenges of cyber security risks, business applications are exposed to numerous attack vectors on a continuous basis. Being exposed to a vulnerability may disrupt confidentiality, integrity and availability of an application and its digital content. This emphasizes on the importance of application security.

Here are top tips about application security:

  • Assume That Infrastructure Is Insecure: As most cloud providers are opaque in terms of security practices, so it is advisable for application developers to implement enough security measures in the application to suffice its security requirements, without relying on the environment. Also, at the time of development, it is often unknown where the application will be deployed or what environment will the application operate in, so it is safe to assume that the environment will be insecure and rely on in built safety features of the application.
  • Secure Each Application Component: It is important to analyze every component of the application to determine the security measures it would require. Some application components such as program execution resources may require intrusion detection & prevention systems, while others such as database or storage may require access controls to prevent unauthorized elements from accessing the data. In addition to securing each application component, the firewall access should be constricted once the application moves to final production so that only appropriate traffic sources can access application resources.
  • Automate Installation & Configuration Of Security Components: Manual installation & configuration processes are susceptible to human error and may be bypassed in case of urgency and business pressure. Automated installation & configuration of security components ensures that the recommended measures are implemented consistently.
  • Test The Security Measures: Do not overlook inspection and validation of implemented security measures. Make it a point to include penetration testing in security testing protocols to gain valuable feedback on security issues that need to be addressed. Organizations may seek assistance from external parties to have an impartial evaluation of the application security and identify security gaps that may not be spotted in internal environment.
  • Focus On Security Monitoring: Configure the security settings to generate critical alerts. It is important to attain correct configuration so that important alerts are not hidden in a blizzard of unimportant data. This requires continuous assessment & configuration updates and use of tools to send detected anomalies to target staff for timely action.
