The certificate names above are what the certificate ASSERTS, not proof this host owns them — a self-signed certificate can claim any subject, so treat a familiar name here as an impersonation attempt rather than an identity.

payload sha-256ef3e5c7b4e471d628b0d12c535ed0134385aba3803b076109d9000d4f5cc454d

The payload hash is the SHA-256 of the file this listener served when it was scanned. A host can change what it serves at any time, so this identifies a sample to look up or analyse rather than describing what it serves now. Only the response’s Content-Type claimed a download — no executable magic bytes were seen — so the bytes behind this hash are unverified.
