Odaily Planet Daily reports: The Sandbox has released a post-incident analysis report regarding the vulnerability incident on August 22. The report reveals that the attacker exploited vulnerabilities in cross-chain configuration contracts on Base and the BNB Smart Chain (BSC), stealing 14,742,341.84 SAND tokens from the Ethereum treasury—approximately 0.5% of the maximum supply—with an estimated economic impact of $1.4968 million, of which approximately $987,000 was actually retained by the attacker. The Ethereum mainnet and Polygon network were unaffected. Until further notice, do not purchase or send SAND on Base or BNB Smart Chain. Contracts deployed on Base and BNB Smart Chain have been permanently disabled and will not be reactivated. The Sandbox stated that its team has reported the attacker’s wallet addresses to blockchain analysis firms TRM Labs and Chainalysis, and has directly communicated with relevant exchanges. The Sandbox has also announced a compensation plan: wallets that legally held cross-chain SAND on Base or BSC prior to the incident will be compensated at a 1:1 ratio with Ethereum-based SAND. Compensation funds will be drawn from The Sandbox treasury without minting new tokens; the claims process will open within the next two weeks and remain open for an additional two weeks.
