The exploit allowed the attacker to bypass the adapter\u2019s authentication checks, execute arbitrary calls, and drain collateral from the affected wallets.<\/p>\n<p>SlowMist estimated the direct loss at about 114.09 ETH. It said roughly 1,300 WETH of debt was also repaid during the attack to unlock collateral tied to the positions.<\/p>\n<p>Aave founder Stani Kulechov said the incident did not involve Aave v3\u2019s core smart contracts. He said:<\/p>\n<blockquote>\n<p>\u201cThis is not Aave v3 contract, it\u2019s third party external adapter built on top of Aave, zero effect on Aave v3.\u201d<\/p>\n<\/blockquote>\n<p>The distinction is significant for Aave, the largest decentralized lending protocol, with more than $33 billion in total value locked. The exploit affected infrastructure layered on top of Aave.<\/p>\n<h2>Fake Safe bypass opened access to collateral<\/h2>\n<p>SlowMist traced the vulnerability to the FlashLoopAdapter\u2019s <code dir=\"ltr\">open()<\/code> and <code dir=\"ltr\">close()<\/code> functions, which checked whether the calling Safe had enabled the adapter as a module.<\/p>\n<p>That verification could be spoofed.<\/p>\n<aside id=\"cs-inline-newsletter-1\" class=\"cs-inline-newsletter\" data-inline-newsletter=\"\" data-newsletter-placement=\"article-midpoint\" data-newsletter-pending-label=\"Joining\u2026\" data-newsletter-pending-status=\"Joining The Catalyst\u2026\" data-newsletter-email-required-message=\"Before sending, please provide your email address.\" aria-labelledby=\"cs-inline-newsletter-1-title\" aria-describedby=\"cs-inline-newsletter-1-copy\">\n<div class=\"cs-inline-newsletter__inner\">\n<div class=\"cs-inline-newsletter__content\"> <span class=\"cs-inline-newsletter__eyebrow\"> <i class=\"fa-regular fa-envelope\" aria-hidden=\"true\"\/> The Catalyst <\/span><\/p>\n<h2 id=\"cs-inline-newsletter-1-title\" class=\"cs-inline-newsletter__title\">What\u2019s moving crypto.

The adapter then accepted the forged authentication and proceeded to its internal swap function.<\/p>\n<p>The more serious weakness came next. The adapter allowed the caller to specify both the router and calldata used in an external contract call.<\/p>\n<p>The attacker pointed the router back at the victim Safe and supplied instructions invoking Safe\u2019s <code dir=\"ltr\">execTransactionFromModule<\/code> function. Because the FlashLoopAdapter was already enabled as a module on the affected wallets, that call gave the attacker a path to execute transactions through the victims\u2019 Safes.<\/p>\n<p>SlowMist said the technique was used to withdraw weETH and collateral associated with Aave positions from two multisig wallets.<\/p>\n<p>The incident highlights a recurring risk in decentralized finance: protocol security can remain intact while integrations built around it create separate attack surfaces.<\/p>\n<p>For Aave, the immediate exposure appears contained to users of the vulnerable adapter. The next question is whether other wallets enabled the same module and whether the adapter\u2019s developers identify additional affected positions before attackers can reuse the same authentication flaw.<\/p>\n<\/div>\n<p>Crime,Featured,Hacks,Lending,Aave,ETHAave,ETH#Crypto #hackers #exploit #thirdparty #Aave #tool #steal #ETH1790969568<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A third-party lending adapter built on Aave was exploited to steal about 114 ETH, worth over $300,000, while the protocol itself remained unaffected.
