# scope: asn 3527 — https://publicmosaic.com/asn/3527
# rev:2 — alert tcp on address and port; alert tls with tls.cert_fingerprint only where the full
#   certificate SHA-256 is published. REPLACE any rev:1 file (every rule was alert tls) rather than
#   loading it beside this one: a same-sid different-text pair is a duplicate Suricata refuses.
# live set only — archived episodes omitted: 0
# Rules may lag a withdrawal by up to five minutes (edge cache); the hub page is authoritative.
