🚨 Real Case Alert | $27 Million Painful Lesson: How Malware Breached Top Multi-Signature Protection
💸 Event Core
According to reports, a high-net-worth user Babur lost approximately $27 million in cryptocurrency assets due to executing a malicious file that infected his device. The attackers stole the signature keys required for his Ethereum Safe multi-signature wallet.
🔍 Attack Deep Dive
This was not a simple phishing attempt, but a targeted advanced attack:
Breaking through ultimate defenses: The attack specifically targeted the Safe multi-signature wallet that requires multiple private keys to co-sign, which is one of the 'ultimate defense' solutions for personal assets.
Precision key theft: The malware did not directly steal funds but lurked and located the multi-signature private key files stored on the device, achieving a 'coup de grâce'.
Cross-chain asset transfer: After obtaining the keys, the attackers quickly transferred assets across both Ethereum and Solana chains, increasing tracking difficulty.
💡 Core Security Insights
Hardware isolation is the only answer: For multi-signature wallets managing ultra-high-value assets, each private key must be generated and stored by completely offline hardware wallets, and must never be kept on any connected device.
"Multi-signature" does not equal "absolute security": If all signing devices are exposed to the same network risks (such as being infected by the same malware), the defense significance of multi-signature will be nullified.
Beware of advanced social engineering: The attack began with a "malicious file", which is highly likely to be a highly customized spear-phishing attack.
