This article examines the fundamentals of protecting assets in the age of AI-related crypto-asset risks, drawing on information-leak incidents at Japanese companies. It focuses on practical measures such as managing keys for self-custody wallets and conducting routine checks.
Among the risks surrounding crypto assets in the age of AI are the leakage of personal information and the resulting expansion of fraud. As information-leak incidents at Japanese companies continue, users need to remain alert to multiple points of entry, including fake emails, fake websites and account takeovers.
Regarding crypto-asset storage, assets held on an exchange are managed by the service provider, while users manage the private keys in self-custody wallets. A basic understanding is required of how to handle recovery phrases, the importance of never giving private keys to third parties and the difficulty of reversing transfers.
According to a report by CertiK, there were 344 crypto-asset and blockchain-related security incidents, with total losses exceeding $1.3 billion. The six main risks are fake websites and impersonation, account and key compromise, excessive approval permissions, operator compromise, DeFi design risks and misuse of personal information.
Practical measures for beginners include checking points of entry, enabling multifactor authentication on accounts, strictly protecting private keys and recovery phrases, reviewing transfer details in advance, separating assets by purpose and limiting publicly available information. As a daily habit, it is important to review permission displays and approval histories on screen.
Looking ahead, the Blockchain Promotion Association plans to hold seminars on the latest security trends, and efforts to share CertiK’s expertise are expected to continue.
