I’m looking for an experienced Linux incident response / sysadmin to help with a server issue.
A Linux server previously had an xmrig miner infection. Most artefacts have been removed, but something on the system is still intermittently attempting to download a miner script via wget.
The application code has been thoroughly checked and appears clean. This looks like a system-level persistence issue (cron, systemd service/timer, user-level service, SSH abuse, etc.).
What I’m looking for: • Identify and remove the persistence mechanism • Confirm whether there is any evidence of data access/exfiltration • Advise whether the server is safe to keep or if a rebuild is recommended
Context: • Ubuntu server • Node.js / Next.js app • PM2 • auditd already enabled • Sensitive app secrets will be rotated after the work
Credentials WILL be checked prior to work commencing
