AI summary of the source article
Layer-1 blockchain Qubic suspended network operations after attackers drained 1,404 wallets of 2.94 trillion QU tokens, worth up to $1.4 million. The exploit stemmed from insufficient randomness in wallet seed generation on certain Apple-device configurations.
Why it matters
The incident also raises broader questions about wallet security across cryptocurrency networks. Although blockchain consensus mechanisms can remain uncompromised, weaknesses in wallet software can still expose user funds to theft.
Key facts
- Attackers drained approximately 2.94 trillion QU tokens ($1.3 million to $1.4 million) from 1,404 addresses on October 17–18, 2026.
- The vulnerability was caused by insufficient randomness during wallet seed generation across specific Apple-device wallet creation methods.
- Qubic halted its network, leaving 87.1% of stolen tokens immobilized on-chain, while MEXC froze the receiving account holding the remaining 12.9%.
