The Exploit: How It Happened
On October 26, 2020, attackers executed a sophisticated economic exploit on Harvest Finance. By manipulating the prices of stablecoins in Curve Finance's Y pool, they were able to withdraw more assets than they deposited, effectively draining funds from Harvest's liquidity pools. The attackers utilized flash loans to amplify their impact, a tactic that has become increasingly common in DeFi exploits. thecyberpost.com+5Ripple Coin News+5copyright Briefing+5BitcoinWorld+3copyright Briefing+3Ripple Coin News+3
In total, the hackers stole $13 million in USD Coin (USDC) and $11 million in Tether (USDT). Interestingly, they returned $2.5 million shortly after the attack, though the reasons for this partial restitution remain unclear. thecyberpost.com+1ZDNET+1Ripple Coin News+2ZDNET+2thecyberpost.com+2
Immediate Aftermath: Market Reaction and Platform Response
The impact of the exploit was immediate and severe. Harvest Finance's native token, FARM, plummeted by 65% within an hour, reflecting a loss of investor confidence. Additionally, the platform's total value locked (TVL) dropped from over $1 billion to approximately $673 million as users withdrew their funds en masse.
