- Browser-based attacks show a 47% increase in sophistication through WebAssembly exploitation
- File-based crypto jacking increasingly targets enterprise systems through supply chain vulnerabilities
- Cloud infrastructure attacks demonstrate advanced persistent threat (APT) characteristics with long-term resource consumption
Cryptojacking remains a trending nuisance as unauthorized Cryptocurrency mining targets individual clients and organizations. These attacks extend their resource usage strategy and method of eluding security measures to a higher level.
Browser-Based Cryptojacking: Script Injection Vectors
In the context of cryptojacking, smart web browsers mean the use of JavaScript code injection into websites where unsuspecting users login to mine cryptocurrencies during their sessions. These scripts employ WebAssembly to increase mining efficiency and try to hide from detection with the help of slowed CPU usage as well as selective execution of the code.
File-Based Cryptojacking: System-Level Exploitation
File-based attacks infect a system via conventional malware propagation paths, wherein steadfast mining at the system level is attained. These implementations, as a rule, use privileged processes for system access while the consumption of resources is masked through complex process concealment techniques.
Cloud Cryptojacking: Infrastructure Compromise
Container breaches and serverless computing platform exploitation are some of the most common cloud infrastructure attacks that use compromised credentials or misconfigured services. These operations are used for building the mining process in several instances while trying to keep the consumption of resources within characteristic limits.
Security researchers document multiple detection evasion techniques employed across these attack vectors. Browser-based attacks implement selective execution based on system monitoring presence. File-based implementations utilize rootkit techniques to conceal mining processes.

Thus, detection strategies in organizations occur by way of monitoring existing resources and analyzing the behavior of networks. Security teams use EDR solutions to notice the activity of potentially malicious processes on the devices of their organization. To achieve this, cloud service providers make improvements in the level of authentication mechanisms to increase security controls. There has been a shift in the strategies attackers use when attacking cryptocurrency mining as seen above.
