What happened
FFIST's _airdrop() function used predictable randomness via manipulable parameters (last airdrop address, block number). Fixed airdrop amounts (1 token) created pool imbalances, collapsing FFIST price to $1 and allowing attackers to swap small token amounts for disproportionate USD value.
