Hackers can utilize your mobile device for malicious purposes, which could lead to permanent harm to its hardware. Is there a way to detect this seemingly stealthy assault?

To put it simply, the global market cap of all cryptocurrency assets is in the trillions. It’s only going to grow in the future years as more and more digital currencies emerge.

On the other side, fraudsters are continuously coming up with new ways to exploit flaws in consumer products to make money, and the anonymity crypto gives has made it incredibly attractive to them. Phones with internet access are included in this category.

The Cryptojacking Phenomenon: What Is It? Just how does it function on mobile devices?

A form of cyberattack known as “cryptojacking” occurs when a malicious actor takes control of a user’s device and puts it to work mining cryptocurrency. Without your knowledge or permission, the computing capability of your device may be hijacked and utilized to generate crypto for another party by solving cryptographic equations.

Smartphones now have more processing power than supercomputers had even a decade ago, making them a viable option for cryptocurrency mining. This has inevitably made them a favorite target for cryptojacking assaults.

Mobile cryptocurrency mining is possible with both iOS and Android devices. It’s worth noting, though, that Android devices are significantly more susceptible to assaults of any kind than iPhones, especially non-jailbroken iPhones.

Cryptojackers are a growing threat, but how do they manage to infect mobile devices, which are typically more secure than desktop computers?

The most common route for a cryptojacker to infect your mobile device is through the downloading of files from questionable sources. When you avoid utilizing a reputable app store in favor of downloading a file from some sketchy website.

However, attackers can compromise even trusted programs. If they can break in, hackers can inject malicious code and exploit the app to spread malware of various kinds, including cryptojacking malware. Of course, mining malware can also be embedded within a website or ad, concealed within a phishing link, or delivered by email.

As soon as a cryptojacker gains access to your mobile device, it will begin secretly mining cryptocurrency. And it would almost certainly be mining Monero, a cryptocurrency that is notoriously anonymous and challenging to track. One such instance occurred in 2021 when the superhero picture Spider-Man: No Way Home was released, and a threat actor used a file that appeared to be a download of the film but was actually a Monero miner.

Top Indicators That Your Mobile Device Is Infected With Crypto Malware

Different components of your smartphone could be damaged or even rendered useless if infected with a cryptovirus. If your phone is being used to mine bitcoin, you’ll be able to know right away. Listed below are five potential red flags or warning indications.

  • The Temperature Is Rising

Your phone seems to be heating up more quickly than usual? Is it getting uncomfortable to hold, even when you’re not using power-hungry apps? If you set it down, will it still be hot when you pick it up again? If you answered yes to any of these questions, it’s possible that your computer is being utilized for cryptocurrency mining.

  • The battery has a shorter lifespan.

There’s obviously something wrong if you’re having to charge your phone more frequently than usual because the battery life is so much lower than it used to be. And yes, crypto-malware might be the problem.

  • User Experience Is Laggy.

Do even the most basic operations, like setting an alarm or adjusting the volume, cause your smartphone’s UI to stutter and slow down? That’s a warning indication, and it could indicate that a cryptojacker is already present on your device.

  • Applications Are Slow and Frequently Freeze

The frequent occurrence of app crashes, unresponsiveness, freezing, or lag is another red flag that your smartphone is infected with cryptojacking malware. This is because crypto miners consume all of the CPU power.

  • This keyboard is temperamental

Although it may not make sense at first, problems with the keyboard are frequently caused by malicious software. You may have a cryptocurrency miner on your phone if you experience unusual delays in the appearance of the keyboard or other unexpected typing lags.

Any drastic change in your smartphone’s usual operation is usually indicative of a serious problem. Overheating, slowness, crashes, and other problems are common side effects of cryptojacking. There are, however, measures you can take to avoid this.

Mobile Cryptojacking Prevention.

To begin, it’s best to stick to official app stores like Google Play and Apple’s App Store. Even if you have access to such a device, you should exercise caution and conduct some background reading on any software you plan to install. This involves the most fundamental of safeguards, such as checking out customer reviews and researching the manufacturer.

Second, even if the sender’s email address looks safe, you should never click on a link in an unsolicited email. And if you ever have any doubts, run it via one of the many available link checker tools.

While it is essential to keep your operating system up-to-date and install security patches as they become available, you can take additional steps to protect yourself against malware by installing security apps and switching to a private and secure browser.

And if you do end yourself downloading a cryptojacker, take swift action. Starting with either a manual or software removal of the malware is the first recommended step. If it doesn’t work, you could try resetting it to factory settings. But remember, this is a full software restore, so unless you have a backup, you will lose access to everything on your phone. That option should be your very last resort.

Toughen Up Your Smartphone’s Defenses Against Cybercriminals

Malware that steals cryptocurrency, or cryptojacking, will continue to be a problem for a long time. It stands to reason that as smartphone processing power increases, the volume of cryptocurrency that can be mined increases, and the prevalence of such assaults increases as well.

The importance of keeping your smartphone safe, it seems, has never been higher. However, there are numerous options for doing so, including a plethora of free apps that can streamline the process significantly.
