<p>Decentralized exchange <a href="https://www.cryptopolitan.com/dydxs-9m-hack-risk-management-under-scrutiny/" rel="noopener noreferrer nofollow">dYdX</a> has released a post-mortem report regarding a “targeted attack” on its v3 platform in November, resulting in a $9 million loss in its insurance fund, equivalent to approximately 40% of the total fund. The exchange’s investigation has identified the attacker’s identity, and legal actions are being considered against the perpetrator.</p>
<h2 class="wp-block-heading" id="dydx-attacker-s-strategy-and-impact">dYdX attacker’s strategy and impact</h2>
<p>The attacker executed a significant number of 5x leveraged long positions in YFI-USD (Yearn Finance’s native token) across over 100 wallets. By acquiring spot YFI tokens using various addresses, the attacker triggered a 215% surge in the token’s price.&nbsp;</p>
<p>Subsequently, the attacker reinvested their unrealized profits into additional YFI-USD positions, eventually reaching approximately $50 million.</p>
<p>To counteract the attacker’s actions, dYdX adjusted the YFI-USD market’s initial margin requirement while reducing the base and incremental position sizes. However, the attacker persisted, and on November 17, YFI’s price experienced a sudden drop of nearly 30% within an hour.&nbsp;</p>
<p>Despite the plummeting value of their holdings, the attacker failed to close their positions. The exchange’s insurance fund automatically compensated for the losses incurred by the attacker.</p>
<p>In a similar strategy employed a week before the YFI incident, the attacker targeted SUSHI-USD, extracting approximately $5 million in profits.&nbsp;</p>
<p>However, dYdX preemptively increased the initial margin requirement for SUSHI-USD to 100%, thwarting further attempts by the attacker.</p>
<h2 class="wp-block-heading" id="customer-funds-remain-unaffected">Customer funds remain unaffected</h2>
<p>dYdX has <a href="https://dydx.exchange/blog/sushi-yfi-incident" rel="noopener noreferrer nofollow" target="_blank">clarified</a> that no customer funds were impacted by these attacks. Furthermore, it suggested that the attacker did not successfully profit from manipulating the YFI market.</p>
<p>In response to these orchestrated attacks, dYdX has implemented various security enhancements. The exchange has updated its v3 trading platform to include improved open-interest monitoring and alerting mechanisms.&nbsp;</p>
<p>Additionally, the upgraded v4 chain, designed to mitigate risks similar to the November incident, incorporates a new software feature that automatically adjusts the initial margin fraction in response to abnormal price movements.</p>
<h2 class="wp-block-heading" id="future-outlook">Future outlook</h2>
<p>While dYdX continues to communicate with the attacker and explore potential legal actions, it remains committed to bolstering its security measures to safeguard its users and assets.&nbsp;</p>
<p>The exchange’s proactive approach in enhancing its platform’s security and risk management capabilities is aimed at preventing future exploits.</p>
