Decentralized Exchange dYdX Publishes Post-Mortem on Targeted Attack
dYdX, a decentralized exchange, has released a post-mortem report on a “targeted attack” that took place on its v3 platform in November. The attack resulted in a loss of $9 million from dYdX’s insurance fund, representing around 40% of the total fund. According to the report, dYdX has identified the attacker and is in contact with them while exploring legal options.
The Attacker’s Strategy
The attacker opened multiple 5x leveraged long positions in YFI-USD using over 100 wallets. This caused the price of YFI tokens to surge by 215%. The attacker then used their unrealized profits to create more YFI-USD positions, reaching a maximum of $50 million. However, when the YFI price dropped significantly, the attacker failed to close their positions, resulting in losses compensated by dYdX’s insurance fund.
Previous Attack and Prevention Measures
Prior to the YFI incident, the attacker targeted SUSHI-USD using a similar strategy but was unable to withdraw significant profits due to dYdX raising the initial margin requirement. No customer funds were impacted by these attacks. In response to these incidents, dYdX has updated its v3 trading platform for improved open-interest monitoring and alerting. Additionally, the upcoming v4 chain includes features designed to prevent similar risks.
Hot Take: Protecting Against Targeted Attacks
dYdX’s post-mortem report sheds light on the targeted attack it experienced in November. By identifying the attacker and exploring legal options, dYdX is taking steps towards accountability and safeguarding its platform. The attacker’s strategy of leveraging YFI tokens resulted in significant losses compensated by the insurance fund. To prevent future attacks, dYdX has implemented enhanced monitoring and alerting systems on its v3 platform and is preparing to launch the upgraded v4 chain with additional risk prevention features. These measures aim to protect users from orchestrated attacks and maintain the security of decentralized exchanges.
