Bitcoin.org 發出了有點摸不著頭緒的警告：「0.13.0 Binary Safety Warning」。
Bitcoin.org has reason to suspect that the binaries for the upcoming Bitcoin Core release will likely be targeted by state sponsored attackers. As a website, Bitcoin.org does not have the necessary technical resources to guarantee that we can defend ourselves from attackers of this calibre.
而且直接是點名可能是針對中國區的用戶：
We ask the Bitcoin community, and in particular the Chinese Bitcoin community to be extra vigilant when downloading binaries from our website.
由於 Bitcoin.org 全站走 HTTPS，這是在暗示會出現「不小心發出 Bitcoin.org 的 SSL certificate」的事情？另外官方也建議使用 PGP public key 驗證：
We strongly recommend that you download that key, which should have a fingerprint of 01EA5486DE18A882D4C2684590C8019E36C2E964. You should securely verify the signature and hashes before running any Bitcoin Core binaries. This is the safest and most secure way of being confident that the binaries you’re running are the same ones created by the Core Developers.
來拿板凳蹲著看，順便拉一張目前 certificate 看到的資訊，目前是從 RapidSSL SHA256 CA - G3 簽出來：
