- LuBian’s weak encryption gave a hacker full entry to 127,000 Bitcoins with out alert
- A gaming PC and time had been all of the hacker wanted to breach crypto's “most secure” platform
- Over 5,000 wallets compromised and no alarms triggered as billions silently vanished
What started as a silent infiltration into one of many world’s largest cryptocurrency mining swimming pools has now been confirmed as the most important crypto theft in historical past.
The LuBian mining pool, as soon as a dominant power within the Bitcoin community, quietly misplaced over 127,000 Bitcoins in 2020.
The breach was solely uncovered in 2025 by Arkham Intelligence, revealing a staggering $14.5 billion value of stolen belongings that had remained untouched and undetected for half a decade.
A historic breach hidden in plain sight
In contrast, the LuBian hack, valued at round $3.5 billion when it occurred, has since ballooned to $14.5 billion because of the rise in Bitcoin costs.
Regardless of the passage of time, the hacker has held onto all of the stolen funds, with no indicators of large-scale laundering or spending.
Arkham’s investigation means that the LuBian breach probably exploited a elementary weak point within the platform’s safety structure.

Its personal key technology reportedly relied on solely 32 bits of entropy, a dangerously low customary by cryptographic norms, and which allowed the attacker to deploy brute-force assaults with nothing greater than a gaming PC and persistence.
The implication is vital digital belongings had been being guarded with the digital equal of a paper lock.
The hacker, who reportedly compromised over 5,000 wallets, used the vulnerability to entry and siphon almost all of LuBian’s Bitcoin holdings.
The mining pool itself disappeared from the community in 2021, only some months after the theft.
LuBian had as soon as boasted of being the “most secure high-yielding mining pool,” a declare now overshadowed by its catastrophic collapse.
This incident calls consideration to the broader challenge of cyber hygiene inside crypto infrastructure.
Using complete safety suites, sturdy encryption strategies, and superior firewall protections needs to be non-negotiable – but even amongst top-tier gamers, vital oversights stay alarmingly widespread.
The shortage of transparency across the breach till 2025 additionally raises questions on what number of comparable assaults might have gone unnoticed.
The hacker has now been arrested, however the LuBian case is a reminder of the implications of weak digital safety.
It additionally exhibits how simply id theft and systemic failures can converge within the largely unregulated world of cryptocurrency.
