Despite the scale of the breach, SBI Crypto has yet to release an official statement about the attack.
ZachXBT linked the attack to North Korea-backed attackers.
Over the past years, North Korean hackers have intensified their focus on crypto-related exploits as sanctions restrict the regime’s access to traditional financial systems.
This figure is more than the $1.3 billion attributed to the attackers the previous year, highlighting their growing reliance on blockchain-based thefts as revenue streams.
SBI Crypto operates as part of SBI Group, Japan’s largest digital asset conglomerate.
The company also maintains a strong presence on the Bitcoin Cash network, controlling over 21% of its computing share with 900.67 PH/s. Blocks were last mined on that chain just hours before the incident.
It also maintains smaller operations in Litecoin with 3.92 TH/s, most recently finding a block two days ago.
