Combatting Cryptojacking Threats Effectively

Guarding your digital frontier from cryptojacking


Combatting cryptojacking threats effectively.

What is Cryptojacking? Cryptojacking is a type of cyberattack where unauthorized individuals exploit a victim's computing resources (like CPU and GPU power) to mine cryptocurrency. This is done without the knowledge or consent of the device owner, leading to reduced device performance, increased power consumption, and potential hardware damages.

  • Our advanced DNS filtering blocks known malicious domains, thwarting cryptojacking scripts from compromising your resources.
Improved Incident Response

Smart Threat Detection

  • With AI and ML-driven capabilities, We identify suspicious DNS patterns, giving early warnings for potential cryptojacking attempts.
Optimized Network Infrastructure

Customized Security Zones

  • Our Response Policy Zone (RPZ) blocks or redirects requests to cryptojacking domains, ensuring robust protection.
Business Agility and Resilience

Content-Aware Filtering

  • Beyond domains, We inspect DNS request content for cryptojacking indicators, enhancing your defense. By utilizing our comprehensive solutions, you fortify your defenses against cryptojacking.
Real-World Examples of Cryptojacking
  • Coinhive: Launched in 2017, Coinhive provided a script that website owners could embed on their sites to mine the Monero cryptocurrency using the computational power of site visitors. Although presented as an alternative to traditional advertising, it was quickly adopted by attackers who embedded the script in compromised websites, effectively turning visitors into unsuspecting miners.
  • Smominru: This botnet infected over half a million machines, primarily in Russia, India, and Taiwan, and mined Monero. It exploited a Windows vulnerability and became one of the largest cryptojacking campaigns known.
  • Docker Instances: In 2019, hackers targeted misconfigured Docker instances to deploy a cryptojacking malware, leveraging them to mine Monero.
How TCPWave Can Prevent Cryptojacking
  • Advanced DNS Filtering: Our DDI solutions incorporate advanced DNS filtering. Since many cryptojacking scripts like Coinhive operate through specific domains, We can block requests to known malicious domains associated with cryptojacking, preventing the script from being downloaded and executed.
  • AI and ML-Driven Threat Detection: With its integrated artificial intelligence (AI) and machine learning (ML) capabilities, We can identify unusual patterns in DNS requests, providing an early warning system against potential cryptojacking attempts. For instance, a sudden surge in requests to a new, unclassified domain associated with crypto mining can trigger alerts.
  • RPZ (Response Policy Zone): Our Response Policy Zone (RPZ) can be configured to block or redirect requests to known cryptojacking domains. This ensures that even if a user inadvertently clicks on a malicious link or visits a compromised website, the cryptojacking script won't be able to make the necessary DNS requests to start its operation.
Enhanced Security Measures and Awareness
  • Content Filtering: Beyond just domain-based blocking, Our solutions can inspect the content of DNS requests and responses for patterns associated with cryptojacking, adding an extra layer of defense.
  • Continuous Updates: The world of cybersecurity is dynamic, with new threats emerging daily. We continuously update its threat intelligence databases, ensuring that even the newest cryptojacking domains are identified and blocked.
  • Network Monitoring and Forensics: Our comprehensive network monitoring tools can detect unusual spikes in CPU or GPU usage, which are often indicators of cryptojacking activities. By promptly alerting IT teams, swift action can be taken.
  • Education and Awareness: While technology plays a pivotal role, user awareness is crucial in cybersecurity. We can assist organizations in educating their employees about the risks of cryptojacking, making them less susceptible to tactics like phishing emails that may contain cryptojacking codes.
Content Filtering:
  • Identifying Unusual Patterns: Through continuous analysis of DNS requests, Our AI and ML algorithms are adept at recognizing patterns that deviate from the norm. These deviations encompass not only known threats but also novel and evolving cryptojacking techniques.
  • Early Warning System: We act as an early warning system, continuously monitoring network traffic and DNS requests. It scrutinizes traffic for patterns, behaviors, and anomalies that suggest potential cryptojacking attempts. This vigilant monitoring extends beyond typical security measures, enabling the identification of subtle indicators.
  • Rapid Cryptojacking Alerts: Our AI and ML algorithms swiftly detect unusual DNS requests to crypto mining domains, triggering instant alerts. IT teams respond promptly, preventing cryptojacking and safeguarding network and device integrity.

In conclusion: Cryptojacking represents a stealthy and potent threat in the digital age, leveraging the resources of unsuspecting users for illicit gains. However, with robust solutions like those offered by us, organizations can shield themselves effectively against such threats. By combining advanced technology with proactive threat intelligence and user awareness, We ensure that your security is never compromised.
