While the file properties state the file is developed by 'Microsoft Corporation', this is not the case and it is designed just to look like a legitimate Microsoft system file. The application sysnetwk.exe, “Windows System Network Core Module” by Lei Qing has been detected as a potentially unwanted program by 1 anti-malware scanner with very strong indications that the file is a potential threat. This executable runs as a local area network (LAN) Internet proxy server listening on port 8080 and has the ability to intercept and modify all inbound and outbound Internet traffic on the local host.
