Before long, people started to look for new ways to mine cryptocurrency, and cryptojacking was born. Instead of paying for an expensive mining computer, hackers infect regular computers and use them as a network to do their bidding. Unlike traditional currencies, cryptocurrencies like bitcoin aren’t backed by a specific government or bank. It is decentralized and managed in multiple duplicate databases simultaneously across a network of millions of computers that belong to no one person or organization. It uses encryption to control the creation of new coins and verify the transfer of funds. All the while, the cryptocurrency and its owners remain completely anonymous.

Why do some miners cryptojack?

This helped it to slip past enterprise networks, which would just see a seemingly harmless JPEG, rather than the dangerous EXE. It spread rapidly by scanning for a wide variety of vulnerabilities, including MySQL, MS-SQL, Telnet, SSH, RDP and more. The Kobe Bryant wallpaper scheme and the MyKingz What is cryptojacking botnet had something a little unusual in common – they both used celebrity images to spread their attacks at some stage. Despite this, many of the other elements in the attacks were quite different. This meant that Coinhive would receive 100 percent instead, essentially tripling its profits.

tips to prevent cryptojacking attacks

If an attacker can take advantage of a security hole or trick you into installing their malware, they can run a mining script as a background process on your computer—whether it’s a Windows PC, Mac, or Linux system. Attackers have tried to sneak cryptocurrency miners into mobile apps, too—especially Android apps. Hackers use these resources to both steal cryptocurrency from other digital wallets and to allow hijacked computers to do the work so they can mine valuable coins. Browser extensions can help with avoiding websites that host the crypto mining code.2.

• This can involve alterations to help slip it past the latest detection and prevention methods, such as antivirus programs or ad blockers.
• Evolving tools like cloud monitoring and container runtime security scanning can offer additional visibility into cloud environments that may be impacted by unauthorized cryptominers.
• This prevents malicious users from trying to spend bitcoins twice and creates a permanent record of all transactions on a distributed and decentralized ledger.
• While much of this article has taken a negative tone toward cryptojacking, the technique itself isn’t inherently bad.
• Cryptojacking is the unauthorized use of someone else’s compute resources to mine cryptocurrency.
• However, an all-around cybersecurity program is a more comprehensive solution.

Once access is gained, hackers siphon unlimited CPU resources for cryptomining, resulting in a huge increase in account costs. Using this method, hackers can significantly accelerate their efforts of cryptojacking to illicitly mine for currency.
