Update Bitcoin.org is warning that the Bitcoin Core, the as-close-to-official-as-it-gets version of Blockchain consolidation software and Bitcoin wallets, may become the target for an attack.
“Bitcoin.org has reason to suspect that the binaries for the upcoming Bitcoin Core release [version 0.13.0] will likely be targeted by state sponsored attackers,” the organisation says in a post that does not elaborate which state may be be behind the threat or the nature of any attack.
“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.”
The warning makes oblique references to China, saying “We believe Chinese services such as pools and exchanges are most at risk here due to the origin of the attackers.”
The potential problems with Bitcoin Core mean “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.”
A suggested defence is to employ only the key used to sign Bitcoin Core hashes.
