Cryptocurrency exchange Bitget says the hackers who stole roughly $351.6 million in digital assets from its systems used techniques that closely resemble those of known North Korean threat actors.
“Based on IP behavior patterns and on-chain analysis, the attack method in this incident is highly consistent with known patterns of North Korean hacker organizations,” Bitget CEO Gracy Chen said in a Friday post on X.
Chen’s post did not name a specific threat group, and Bitget has not detailed the evidence behind its assessment. She said the incident has been reported to the relevant authorities.
Founded in 2018, Bitget runs a centralized exchange for spot and derivatives crypto trading. It also offers Bitget Wallet, a self-custodial wallet that the company says runs on separate infrastructure and was not affected.
Bitget said its security systems caught the unauthorized transfers on September 24. The funds came from a small number of the exchange’s hot wallets. According to the company, its cold wallets were not touched.
The stolen funds include ETH, XRP, BNB, AVAX, USDT and USDC, spread across several blockchains. XRP accounts for the largest loss on a single chain. According to Chen, some blockchain foundations have frozen wallet addresses linked to the attacker.
The company hasn’t yet worked out how the attacker got in. However, it said the hacker compromised a critical backend system in its wallet infrastructure and abused it to get fraudulent transfers approved. Bitget said private keys were not compromised.
Mandiant and blockchain security firm SlowMist are helping with the investigation.
North Korean state-sponsored hackers have stolen billions of dollars’ worth of cryptocurrency in recent years. The FBI blamed North Korea for the February 2025 heist in which roughly $1.5 billion was stolen from Bybit.
