Security IOC alert for Linux/VPS administrators

We have identified the same previously undocumented-looking Linux malware/persistence pattern on 4 of 6 VPS servers during an incident investigation.

Observed indicators:

• systemd service: httpdconfchecker.service
• executable: /usr/sbin/httpdconfchecker
• fake Apache binary: /usr/bin/apache
• execution: /usr/bin/apache --config=/dev/shm/httpd.json
• fake Apache binary identified internally as XMRig 6.26.0
• downloader observed contacting:
https://d4.appdeploy.online/cx.gz
• suspicious root SSH authorized-key comment:
H

Known SHA-256 samples:

httpdconfchecker
160e76f2608252de0432ff285b54f48d43b6c83893cccd85a5d5ea5a5f569136

fake /usr/bin/apache / XMRig
ff6cb4f217b2cfb3fb730f6d8e165be441c70bcb8c1a5d3d14c62639f96c9aad

One affected system showed the service being created on 2026-09-05 at approximately 22:13 CEST.

If you administer Linux VPSes, please check for:

systemctl status httpdconfchecker

ls -l /usr/sbin/httpdconfchecker /usr/bin/apache

grep -R "httpdconfchecker" /etc/systemd/system

and inspect /root/.ssh/authorized_keys for unfamiliar keys.

We are reporting the samples and IOCs to the hosting provider and malware-analysis platforms. The common initial-access vector is still under investigation.

Please share if you observe the same indicators so the campaign can be mapped quickly.
