VShell configuration

Read from the file without running it. Endpoints are where the sample is configured to connect. An endpoint is listed on this site only if the scanner confirmed it separately. A VShell loader’s only configuration is the address and port it calls. The listener key (vkey) and the salt arrive from the listener when the loader connects, so only sandbox runs that reached a live listener show them.

Pivots: other samples whose configuration carries the same value. A shared value is not evidence of a single operator.
