Luke Dash Jr

Bitcoin core developer Luke Dashjr experienced a significant loss at the start of the new year, reportedly losing over 200 BTC in a hack. Dashjr revealed on Twitter that his PGP key was compromised, leading to the theft of many bitcoins. The stolen bitcoins were transferred to a wallet address using the Bitcoin mixer CoinJoin in four transactions, totaling approximately 216.93 BTC, equivalent to $3.6 million. In November, Dashjr's server was accessed by an unknown individual using new malware/backdoors, and on Christmas day, the server was reaccessed, resulting in the successful theft of over 200 Bitcoins. Binance CEO CZ expressed sympathy and pledged to freeze the funds if they come to Binance, sparking discussions in the crypto community about the risks and challenges of self-custody.

It's well known that I run Gentoo on a Talos II with everything self compiled

they got it all, including a brand new 2FA I made the same day.

(Besides, as someone already pointed out, the wallets weren't on my main system.)

Talos II? It seems likely you were a victim of CVE-2019-15847 : The random number generator of Power9 (DARN instruction) was broken with GCC ->

If your main system (Talos II) was using a weak RNG then your private ssh keys could be compromised relatively easy, allowing the bad guys to get access to any device where you had ssh access. Once they got access they could have installed any backdoor or malicious software.

This exchange or platform is based in United States, or the incident targeted people primarily in United States.

The background of the exchange platform, service, or individuals involved, as it would have been seen or understood at the time of the events.

  • Known history of when and how the service was started.
  • What problems does the company or service claim to solve?
  • What marketing materials were used by the firm or business?
  • Audits performed, and excerpts that may have been included.
  • Business registration documents shown (fake or legitimate).
  • How were people recruited to participate?
  • Public warnings and announcements prior to the event.

Don't Include:

  • Any wording which directly states or implies that the business is/was illegitimate, or that a vulnerability existed.
  • Anything that wasn't reasonably knowable at the time of the event.

There could be more than one section here. If the same platform is involved with multiple incidents, then it can be linked to a main article page.

The Reality

This sections is included if a case involved deception or information that was unknown at the time. Examples include:

  • When the service was actually started (if different than the "official story").
  • Who actually ran a service and their own personal history.
  • How the service was structured behind the scenes. (For example, there was no "trading bot".)
  • Details of what audits reported and how vulnerabilities were missed during auditing.
