0.13.0 Binary Safety Warning
17 August 2016
Summary

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. We ask the Bitcoin community, and in
particular the Chinese Bitcoin community to be extra vigilant when
downloading binaries from our website.

In such a situation, not being careful before you download binaries
could cause you to lose all your coins. This malicious software might
also cause your computer to participate in attacks against the Bitcoin
network. We
believe Chinese services such as pools and exchanges are
most at risk here due to the origin of the attackers.
Mitigation

The hashes of Bitcoin Core binaries are cryptographically signed with this key.

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.
