Understanding the Sturdy Finance Exploit

The Sturdy Finance hack, which unfolded recently, wasn't a simple case of password theft or a server intrusion. Decentralized lending platform Sturdy Finance has suffered a major security breach resulting in the loss of approximately $800,000 worth of ether (ETH). The attack, executed by an unidentified individual, exploited a reentrancy vulnerability within the system, ultimately manipulating a faulty priceInstead, it leveraged a more intricate weakness in the protocol's smart contract code. Attacker drains $800K from DeFi protocol Sturdy Finance cointelegraph.com, UTC cointelegraph.comThe attack centered around two key vulnerabilities: a reentrancy vulnerability and a faulty price oracle.Let's break down what these terms mean in the context of DeFi.

What is a Reentrancy Vulnerability?

A reentrancy vulnerability occurs when a smart contract calls another external contract function before it has finished updating its own internal state. Decentralized finance (DeFi) protocol Sturdy Finance has lost 442 Ether (ETH), worth almost $800,000 when writing, to a security exploit. The attacker exploited a vulnerability that eventually Attacker drains $800K from DeFi protocol Sturdy FinanceImagine a scenario where you're withdrawing funds from a bank.Before the bank confirms your withdrawal and updates your balance, an attacker can re-enter the withdrawal function multiple times, draining more funds than they should be able to.This is essentially what happened with Sturdy Finance.The attacker exploited this flaw to repeatedly call the withdrawal function before the system could properly update its records.

The Role of a Faulty Price Oracle

Price oracles are essential components of DeFi platforms.They provide real-time price feeds for various crypto assets, enabling lending, borrowing, and trading functionalities.However, if an oracle is inaccurate or susceptible to manipulation, it can create opportunities for attackers.In the case of Sturdy Finance, the attacker managed to manipulate the price oracle, making it appear as though they were entitled to withdraw more funds than they actually had. Liquidations in Decentralized Finance (DeFi) are both a blessing and a curse whereas liquidations prevent lenders from capital loss, they simultaneously lead to liquidation spirals and system-wide failures.This manipulation, combined with the reentrancy vulnerability, allowed them to drain a significant amount of ETH from the protocol.It's crucial to use reputable and reliable price oracles to mitigate this kind of risk.

Essentially, the attacker combined these two vulnerabilities – the reentrancy flaw and the faulty price oracle – in a sophisticated attack strategy to siphon off approximately 442 ETH, valued at around $800,000 at the time of the exploit. The lending platform responded by pausing all markets and assuring its community that no additional funds were at risk.The attacker then sent the stolen funds to Tornado Cash, a cryptocurrency mixer, likely in an attempt to obscure the origin of the funds and hinder traceability.

Immediate Response and Mitigation Efforts
