Ofo Domain Security

generated: '2026-08-26'
method: probed
source: >-
  Direct TCP/TLS probe of 47.93.164.86 (ofo.com) plus DNS queries against 8.8.8.8 for TXT, MX,
  CAA, DS and DNSKEY on ofo.com.
scope: >-
  ofo.com only — the company's own former primary host. forgeglobal.com, which is currently the
  only URL in apis.yml common[], is a third-party secondary-market trading venue; its security
  posture is Forge Global's and is deliberately NOT probed or attributed to Ofo here.
pointer_emitted: false
pointer_note: >-
  No `DomainSecurity` (or `Security`) pointer is wired into apis.yml for this file. The scorer's
  `reg_security_posture` check awards points for the pointer alone, and Ofo publishes no security
  posture — every control below is absent and the web origin is offline. Wiring a pointer here
  would convert a verified absence into a scored presence.

    The A record resolves (47.93.164.86, Aliyun) and the registration is live through Alibaba
    Cloud to 2027-09-08, but the origin completes no TCP handshake on either web port, so TLS,
    HSTS and certificate posture cannot be observed at all — the web presence is off, not merely
    misconfigured.

    note: >-
      TWO v=spf1 TXT records are published on the same name. RFC 7208 §4.5 makes that a
      permanent error — a receiver that finds more than one SPF record MUST return permerror,
      so in practice this domain has no usable SPF policy despite publishing two.

  note: >-
    Corporate mail is still delegated to NetEase business mail and the domain is still being
    renewed, so the registration is administered even though the website is gone. Mail
    authentication is nonetheless unusable: conflicting SPF records and no DMARC record at all.
