What is Illicit Cryptocurrency Mining?

In addition to high resource usage, overheating is another sign of cryptojacking. Although not as effective as a JavaScript blocker at removing malicious code, ad-blockers should prevent most malicious advertising code running on your device. Browser Plug-ins such as AdBlock, uBlock, AdGuard, etc. are good choices.

Normally, this is a sign to free up some storage space or request a new device/component from the IT department. However, an unusually slow laptop can also be the sign of something more sinister – cryptojacking.

While there is no definitive way to gauge how much cryptocurrency is mined by hackers through cryptojacking, Securus has found that the practice is common and shows no signs of slowing down. Regardless of the method used, the code runs sophisticated mathematical algorithms on the victim’s computer for cryptocurrency transactions and sends the results to a server controlled by the hacker. Cybercriminals employ this tactic to compel users to pay the ransom using specific online payment methods, such as cryptocurrencies in order to obtain the decryption key. If users fail to pay promptly their data will be lost permanently, or the ransom amount will increase rapidly.

We know that keeping an eye on tools like IPSs, firewalling, and endpoint protection network-wide sounds like a lot. However, Network Security Monitoring can be easily outsourced and is much more affordable than suffering an attack! Our security analysts can monitor your network from afar and immediately notify you should anything untoward happen. You see, not all intrusion attempts counted by the threat network are malicious – some are simply times where devices and networks have been innocently scanned for or “pinged”. A UK security researcher has discovered that cyber criminals have been using public sector websites, including that of the UK’s Information Commissioner’s Office for cryptojacking.

Known Cryptojacking Threats

It is an online threat that hides on a computer or mobile device and uses the machine’s hardware resources to mine cryptocurrency without paying for electricity and other mining resources. Getting infected with this type of malware requires just one click on a malicious link in an email or website, and it loads cryptomining code directly on the computer or mobile device. A legitimate way to mine cryptocurrency is to use a farm of computers with groups of people and share the rewards. In a cryptojacking attack, an attacker uses malware or malicious JavaScript pages to use third-party computers to mine for the attacker.

• When an attacker obtains the private key, they can drain the user’s cryptocurrency account and transfer funds to an attacker’s account.
• FIM – File integrity monitoring can help organisations to identify deviations from a ‘known good’ baseline, to detect unauthorised file changes that could indicate a cryptojacking attack.
• The technique of threat actors hosting cryptocurrency mining malware on GitHub was first reported by Avast in 2018 (see report).
• Cybercriminals continuously modify code and come up with new ways to embed those updated scripts onto your computers.
• While it’s not strictly new, it was recently discovered to be exploiting Microsoft Exchange vulnerabilities used in the Hafnium attacks to deploy malware and harvest credentials and then utilising the infected devices to mine Monero.

The cryptojacking software aims to use just enough processing power of the infected host machine to mine the cryptocurrency without slowing that machine too much that the user suspects foul play. Hackers have found they can make easy money by stealing the computing resources from victims computers and using that power for the mining. This https://www.tokenexus.com/what-is-an-energi-coin-and-what-are-the-most-important-advantages-of-it/ method is called cryptojacking, and we will cover this exploit next. The actual process of secure cryptocurrency transactions is a resource-intensive process using encrypted wallets and keys. Also, every time a cryptocurrency transaction occurs, the blockchain must be time-stamped and updated to verify the authenticity of the information.

Cyber Security Trends: Top 5 Threats to Watch Out for This Year

Credential stealing is popular to gain access to a system and install background processes that steal cryptocurrency. The PowerGhost malware steals Windows credentials and then uses the popular EternalBlue exploit to spread to other Windows machines. It attempts to disable antivirus software along with any competing cryptomining software. To be the first to solve a mathematical problem, miners need powerful computing resources.

The AppCheck web application vulnerability scanner has a full native understanding of web application logic, including Single Page Applications (SPAs), and renders and evaluates them in the exact same way as a user web browser does. This includes all client-side JavaScript, allowing it to be evaluated and analysed. Our custom JavaScript Crypto Miner detection module works by loading each page within a sandboxed web browser and then detecting attempts by the browser to communicate with Crypto Mining services.
