<p>Socket, a key player in <a href="https://coinpedia.org/news/wise-lending-falls-prey-to-flash-loan-hack-a-464000-defi-breach/">decentralized finance (DeFi)</a>, encountered a major setback recently, grappling with a security breach that led to losses exceeding $3.3 million. This breach, linked to a vulnerability in user input validation, has sent ripples through the DeFi community, prompting a reevaluation of security measures. </p> 
<p>Needless to say, the blow is huge and many are left impacted and shocked. Here’s what you need to know. </p> 
<h2 class="wp-block-heading" id="h-understanding-the-breach">Understanding the Breach </h2> 
<p>Blockchain security firm PeckShield highlighted the breach, attributing it to a crucial flaw in Socket’s user input validation system. The vulnerability surfaced in wallets that had generously granted infinite approvals to Socket contracts, providing an opportunity for exploitation.</p> 
<p>Upon investigation, the flaw was traced back to a specific route added just days before the attack. Exploiting this vulnerability, attackers executed unauthorized fund transfers, causing financial havoc.</p>
