In 2019, Symantec discovered eight separate apps available in the Microsoft Store that would secretly mine cryptocurrency with the resources of whoever downloaded them. The apps supposedly came from three different developers, although Symantec suspects that the same individual or organization was behind them all. Krebs highlighted the fact that Coinhive generally didn’t respond to complaints from site visitors who were having their resources hijacked on hacked websites.

Why cryptojacking is popular

Government websites and more than 4,000 others worldwide were exploited by cryptojacking viruses. The malware is also capable of using scanning tools to identify other exposed Docker daemon APIs in order to expand its cryptojacking operations further. Bitcoin’s success inspired dozens of other cryptocurrencies that operate in more or less the same way. Today, people all over the world use cryptocurrencies to buy things, sell things, and make investments. We’ll personalize the session to your org’s data security needs and answer any questions.

• An alternative cryptojacking approach is sometimes called drive-by cryptomining.
• And Symantec found that the prevalence of cryptojacking changes as the value of cryptocurrencies fluctuates—something to bear in mind during a crypto bull run.
• It was relatively simple to hack vulnerable sites and insert the Coinhive script onto them, with any Monero mined by the site’s visitors going straight to the wallets of the attackers.
• Often attackers will use the initially compromised system to move their cryptojacking laterally into other network devices.
• Cryptojacking is a form of malicious cryptomining that allows cybercriminals to mine cryptocurrency using another entity’s computing power.
• One of the top symptoms of cryptojacking is a decrease in performance in your computing devices.

How to prevent cryptojacking

It actually opens up a new and legitimate opportunity for websites to raise revenue. This approach is expensive, both in terms of the electricity it uses, and the amount of equipment it requires. A lot of people want to make money through cryptomining, but either don’t have the finances to get started or simply don’t want to pay. However, with a little ingenuity and a skewed moral compass, there is another way – cryptojacking. A single hijacked device won’t make an attacker a whole lot of cash, but if they target thousands or millions of computers, tablets, smartphones and IoT devices, it can be a lucrative moneymaker. This term, a portmanteau of ‘cryptocurrency’ and ‘hijacking,’ succinctly describes the stealthy and unauthorized mining operations.

• The larger cryptocurrencies use teams of miners running dedicated computer rigs to complete the necessary mathematical calculations.
• Runtime Application Self-Protection (RASP) – Real-time attack detection and prevention from your application runtime environment goes wherever your applications go.
• In some instances, this can allow hackers to benefit from the huge computing resources of large server farms practically for free.
• It can be a very lucrative business – mining thousands or millions in cryptocurrencies, often without the targets ever knowing.
• Vlad’s love for technology and writing created rich soil for his interest in cybersecurity to sprout into a full-on passion.Before becoming a Security Analyst, he covered tech and security topics.
• The other approach to cryptojacking can yield significantly higher hash rates — and revenues for attackers.

How to Protect Yourself from Cryptojacking in the Browser

The resource-intensive process of cryptojacking can cause computing devices to overheat. Also related to overheating devices are fans that run longer than they should in an attempt to cool down the system. Here are some of the methods you can use to detect cryptojacking before it’s too late. After being executed, the cryptomining script runs in background, without the knowledge of the user. Cryptocurrency was an accidental invention in 2009 by Satoshi Nakamoto (a pseudonym), who’s intent was to create a centralized cash system. Unable to achieve this, Nakamoto instead developed a digital cash system that was based on the accuracy and transparency of accounts, balances, and recording of transactions to prevent double-spending.

When a crook can mine for cryptocurrency on a seemingly limitless pool of free compute resources from victim machines, the upside for them is huge. Cryptojacking only exists with cryptocurrencies What is cryptojacking that use the proof-of-work consensus protocol. This subset of coins uses computational power to verify transactions and secure the network, and by doing that, they are rewarded with coins.

Bitcoin was the first cryptocurrency created in 2009, and the first instance of blockchain technology ever used. People are increasingly trying to sneak cryptocurrency miners into legitimate-seeming software. Google had to remove Android apps with cryptocurrency miners hidden in them from the Google Play Store, and Apple has removed Mac apps with cryptocurrency miners from the Mac App Store.

In 2018, a cybersecurity firm called RedLock posted a report that detailed how cybercriminals had infiltrated Tesla’s AWS cloud infrastructure and used it to mine cryptocurrency. In a more general sense, once various cryptojacking scripts became popular, antivirus programs and adblockers began to block them. This meant that a smaller portion of site visitors would lend their resources to cryptojacking scripts, decreasing the pool of targets that either site owners or cybercriminals could make money from.
