A marked day is a UTC day the feed listed this address. The feed keeps a listener for up to 90 days after its last confirmation, so a listed day is not a confirmation. A listener no longer in the feed is drawn to its last confirmation.

Clustering values from these files’ configurations. A value marked shared recurs in configurations across more than three unrelated networks. It is not evidence of a single operator.

vkey = salt · sharedqwe123qwe · 1 file

3 of the 4 files are VShell loaders whose configuration was read from the file. 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.
