Bitfinex Thwarts $15 Billion XRP Attack Exploiting Partial Payment Loophole
• Nearly $15 billion worth of XRP moved in failed exploit attempt on Bitfinex exchange • Transaction aimed to trick Bitfinex into thinking it received funds, possibly enabling a hack • Bitfinex systems flagged it as a "partial payment," an XRP Ledger feature reducing received amount • Attack failed since Bitfinex properly handled transaction data showing real amount delivered • Partial payments are a known attack vector if institutions assume Amount field is always full amount
