Token Avica dựa trên Solana giảm 49% sau vụ tấn công vào cơ sở hạ tầng Rain

The Huoxing Finance report states that Rain, a Solana-based crypto debit card infrastructure, was hacked due to vulnerabilities in outdated smart contracts, resulting in the theft of approximately $1.1 million. The token AVICI of the affected crypto bank Avici plunged from its 24-hour high of $0.43 to a historic low of $0.217, a drop of 49%, before recovering to around $0.378. Avici confirmed that the attack only affected the contract managing funds for card top-ups and spending; its self-custodied wallets remained unaffected, and it pledged to fully reimburse affected balances. In this incident, 1,685 Avici users lost approximately $500,800; another crypto bank, Tria, also had 636 users affected, with losses exceeding $430,000. The discrepancy between the $1.1 million tracked on-chain and Avici’s reported losses indicates that other protocols supported by Rain were also compromised. Transaction data shows the attacker repeatedly submitted signed authorizations to add themselves as administrator of the card collateral accounts and withdraw balances; the stolen stablecoins were exchanged for SOL, bridged to Ethereum, and ultimately funneled into the mixer Tornado Cash. Avici has filed a report with the FBI’s Internet Crime Complaint Center. This incident also exposes custody transfer issues underlying some self-custodied crypto cards: although users control their wallets, funds used for spending are transferred to third-party contracts.
