The breach went unnoticed for more than four years and eclipses the recent $1.5 billion Bybit breach.<\/p>\n<p>Lubian, once a top-10 Bitcoin mining pool that controlled nearly 6% of the global hash rate, abruptly shut down in early 2021. At the time, the crypto community attributed the exit to tightening regulations in China and Iran, where many of Lubian\u2019s mining machines were believed to operate. <\/p>\n<p>Arkham\u2019s findings now point to a devastating security failure as the real cause. The firm believes the hack stemmed from weak private key generation methods.<\/p>\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\">\n<div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">BREAKING: ARKHAM UNCOVERS $3.5B HEIST \u2013 THE LARGEST EVER<\/p>\n<p>LuBian was a Chinese mining pool with facilities in China &amp; Iran.

In a desperate recovery effort, Lubian issued over 1,500 small Bitcoin transactions containing pleas for the return of the stolen assets. The pool also moved its remaining 11,880 BTC into designated recovery wallets.<\/p>\n<p>The hacker has not attempted to cash out the stolen coins, which remain idle apart from a 2024 consolidation into a new wallet address.
