All Cases
4 publishedTriple-Server XWorm Infection: Tracing the Full Attack Chain
A customer accused us of installing malware after all three of his servers were infected with XWorm RAT — cryptocurrency clipboard addresses were being silently replaced. Our engineer traced the entry vector to Linken Sphere 2 through PowerShell event logs and VirusTotal analysis.
The Double-IP Routing Conflict: SSH Restored in 31 Minutes
Adding a second IPv4 to a VPS triggered asymmetric routing, cutting off SSH, WinSCP, and the management panel entirely. With critical data on the line and no reboot permitted, our engineer applied policy-based routing at the kernel level — zero data loss.
VPS OBS Streaming: From 403 to RTMP + AutoDJ in 7 Days
A customer set out to build a WebTV platform on a single VPS. Over seven days, our engineers resolved SSL misconfiguration, deployed Nginx RTMP with OBS ingest and HLS playback, fixed the multi-worker /stat reporting bug, enabled WebDAV PUT uploads, and deployed a Node.js AutoDJ controller for 24/7 automated broadcasting — all without a single server reset.
How We Cut ASP.NET Core Latency from 17s to Under 1s
An ASP.NET Core API responded instantly on localhost but took 13–17 seconds externally. Two root causes were uncovered — a rogue IIS module adding 9 seconds, followed by 3 seconds of architectural pipeline overhead. Our engineers eliminated both, achieving a 0.9s TTFB with no data loss and no OS reload.
