A recent report by Wiz Threat Research highlights a widespread cryptojacking campaign targeting publicly exposed DevOps web servers, including Nomad, Consul, Docker, and Gitea applications. Attackers exploit misconfigurations in these tools to deploy cryptocurrency miners, consuming system resources and increasing operational costs.

You Should Know: How to Detect and Prevent Cryptojacking Attacks
1. Check for Unusual CPU Usage
Cryptojacking malware often spikes CPU usage. Monitor your systems with:
top -o %CPU Linux/macOS Get-Process | Sort-Object CPU -Descending PowerShell
2. Identify Suspicious Containers (Docker)
Attackers often deploy miners via Docker. List running containers:
docker ps docker stats Monitor resource usage
3. Scan for Cryptominer Processes
Common miners like `XMRig` can be detected via:
ps aux | grep -i "xmrig|minerd|cpuminer"
4. Secure Exposed APIs (Nomad/Consul)
Ensure Nomad and Consul APIs are not publicly accessible. Use firewall rules:
ufw deny 4646 Nomad default port ufw deny 8500 Consul HTTP API
5. Monitor Network Traffic
Detect connections to known mining pools:
netstat -tulnp | grep -E "xmrig|minexmr|monero"
6. Patch and Update DevOps Tools
Ensure all tools are updated:
docker update --all Update all containers consul version Check Consul version
7. Use Security Tools for Detection
- Falco (Runtime Security)
falco -r cryptojacking_rules.yaml
- Wazuh (Endpoint Monitoring)
wazuh-logtest -f /var/ossec/logs/alerts.log
What Undercode Say
Cryptojacking remains a stealthy yet costly threat, especially in misconfigured DevOps environments. Attackers exploit automation tools to mine cryptocurrency silently. Regular audits, network monitoring, and strict access controls are essential.
Expected Output:
- High CPU usage alerts
- Unauthorized Docker containers
- Connections to mining pools (e.g.,
minexmr.com) - Unpatched DevOps tools (Nomad, Consul, Gitea)
Prediction
As cloud-native adoption grows, cryptojacking attacks will increasingly target Kubernetes, serverless functions, and CI/CD pipelines. Zero-trust security models will become critical.
