Forensic narrative
The loss of today's HundredFinance hack is ~$7m.The root cause appears the attacker donates 200 WBTC to inflate hWBTC's exchange rate so that even a tiny amount (2 wei) of hWBTC can basically drain current lending pools. Attack method (per SlowMist): Contract Vulnerability. Reported loss: $ 7,000,000.
