Cryptojacking occurs when hackers stealthily install cryptocurrency mining software (like Monero miners) on your hardware or cloud servers. While it rarely steals data, it is a severe resource drain. It causes servers to overheat, slows business-critical applications to a crawl, and can cause monthly cloud computing bills (AWS/Azure) to skyrocket by thousands of dollars overnight.
Warning Signs Your Business May Be Affected
- Server or workstation fans running at maximum speed constantly.
- CPU usage pinned at 90-100% with no legitimate intensive applications running.
- Battery draining incredibly fast on laptops.
- Shocking spikes in AWS/Azure/GCP computing bills.
- Antivirus alerts for "CoinMiner" or "Riskware.Miner".
How SystemHelpDesk Protects Your Business
Cloud Posture Management. We lock down cloud IAM roles to prevent unauthorized spinning up of massive compute instances.
Endpoint Resource Monitoring. We alert on sustained, unusual CPU spikes across the fleet.
Browser Protection. We block in-browser JavaScript miners (WebAssembly) that run when visiting compromised sites.
What To Do Right Now If You Suspect Infection (Troubleshooting & Removal)
-
Kill the Process: Use Task Manager (or
topon Linux) to identify and kill the high-CPU process. - Check Persistence: Miners almost always set up a Scheduled Task or cron job to restart. You must find and delete it.
- Audit Cloud Keys: If this happened in AWS/Azure, immediately rotate all access keys and review CloudTrail logs.
- Contact Support: Call SystemHelpDesk at 855-783-7555 for a full forensic sweep to ensure the miner wasn't dropped by a backdoor.
How We Help You Recover
We completely isolate the threat, conduct deep forensic analysis to identify the root cause, and rebuild affected systems from trusted baselines. We ensure the attacker's persistence mechanisms are eradicated so your business can return to normal operations safely.
Frequently Asked Questions
Is this a serious threat?
Yes. These classifications represent critical breaches of your security perimeter. Immediate response is required to prevent data loss or ransomware deployment.
Can I just run antivirus?
Standard antivirus is often insufficient for advanced threats, which employ evasion techniques or rootkit functionality. A coordinated incident response is safer.
How do I prevent this?
Strict application whitelisting, mandatory Multi-Factor Authentication (MFA), robust EDR monitoring, and continuous employee training form the bedrock of prevention.
