Apriori, a trading infrastructure project backed by YZi Labs, has reportedly suffered a suspected Sybil attack during its recent token airdrop. Approximately 80% of the airdropped tokens were claimed by a cluster of 5,800 wallets, which were deployed and funded with BNB before the airdrop conditions were publicly announced. This has raised concerns about potential insider information leaks. The market capitalization of Apriori's APR token currently stands at approximately $93 million, marking a 60% decline from its peak on the first day of trading.
