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

Cyber Security Concerns Of Smartphone Users

As the ‘Work From Home’ and ‘Bring Your Own Device’ culture has gained popularity, organizations have increased their attention towards mobile security. Most employees routinely access organizational data from their personal mobile devices, cyber criminals also try to gain on this opportunity. So, organizations have to keep their employees informed about major cyber security concerns that can be woven around smartphones.

Here are some major cyber security concerns of smartphone users:

  • Data Leakage: Data leakage refers to unauthorized transfer of data from within an organization’s systems to an external destination or recipient. It is one of the most bothersome cyber security threats for enterprises. In order to combat the issue of data leakage, organizations need to implement an app vetting process that does not overwhelm the administrator and does not frustrate the users as well. However, this doesn’t help in taking care of data leakage resulting from user error such as transferring company files onto public cloud, copying confidential information to a wrong place, forwarding an email to unintended recipient, etc.
  • Social Engineering: It is a manipulation technique that exploits user error to gain private information, unauthorized access, etc. These scams are also known as ‘human hacking’ scams because these scams work by luring unsuspecting users into exposing data, spreading malware infections, or giving access to restricted systems. Social engineering scams usually aim at theft of information as well as sabotaging organization’s reputation by disrupting or corrupting data. Common examples of social engineering attacks include phishing attacks, baiting attacks, physical breach, pre-texting attacks, access tail-gaiting attacks, quid pro quo attacks, scareware attacks, etc.
  • Wi-Fi Interference: A mobile device is secure only in case the network through which data is transmitted is secure. Cyber criminals find an array of ways to intercept the transmission. Some of the tactics include setting up fake Wi-Fi networks, intercepting communications transferred across public networks, etc. Organizations can combat this issue by motivating users to download and make use of VPN.
  • Cryptojacking Attacks: Cryptojacking is a type of attack where cyber criminals use victim’s device for mining cryptocurrency without victim’s knowledge. The cryptomining process relies on the user’s resources such as mobile device processor, network, data, storage, etc. This reduces the performance level of the mobile device.
