The notorious North Korean hacking group, Lazarus, has reportedly set its sights on another target in the decentralized finance (DeFi) space: the OKX DEX aggregator service. The major cryptocurrency exchange has taken swift action, temporarily suspending the service to implement security upgrades and address vulnerabilities.
The decentralized finance (DeFi) world is once again on high alert, as the Lazarus Group, a state-sponsored hacking group from North Korea, has been linked to attempted misuse of OKX’s decentralized exchange (DEX) aggregator service. This incident underscores the persistent threat posed by sophisticated cybercriminals to the rapidly evolving DeFi landscape.
Lazarus Group Targets OKX DEX Aggregator
OKX, a leading cryptocurrency exchange, announced the temporary suspension of its DEX aggregator service following the detection of “a coordinated effort by Lazarus group to misuse our defi services.” This proactive measure, taken after consultations with regulators, aims to prevent further exploitation and allow for the implementation of crucial security enhancements.
In a statement addressed to its community, OKX acknowledged the incident and framed it within a broader context of “targeted media attacks” and “competitive attacks” designed to undermine the exchange’s operations. “Over the past few days, we’ve faced targeted media attacks questioning our integrity and operations,” the statement read. “While we usually stay focused on building and protecting the industry, we can’t ignore the fact that these attacks are happening at a time when we are actively fighting against financial crime.”
The exchange emphasized its commitment to transparency and collaboration, stating that it is “working closely with blockchain explorers to correct incomplete labeling.” The goal is to ensure that blockchain explorers accurately identify the actual DEX processing trades, rather than mistakenly attributing them to the OKX aggregator. This distinction is crucial for maintaining clarity and accountability within the DeFi ecosystem.
The exchange has already implemented several security measures in response to the OKX DEX threat, including:
- Hacker Address Detection System: A newly launched system for its Web3 DEX aggregator designed to identify known hacker addresses.
- Real-time CEX Blocking: A system to track and block the latest hacker addresses within its centralized exchange (CEX) system in real-time.
OKX Clarifies Role as DEX Aggregator, Not Custodian
The exchange explicitly clarified its role as a DEX aggregator, not a custodian of customer assets. “One thing we want to make absolutely clear: OKX Web3 is a DEX aggregator, not a custodian of customer assets,” the statement emphasized. “Our role is to provide access to liquidity across multiple protocols, offering users the most efficient peer-to-peer trading experience possible.”
OKX CEO Star further elaborated on the nature of the DEX aggregator service, comparing it to software and service providers in the traditional internet industry. “OKX DEX aggregators don’t touch or store customer’s private key, don’t custody customer’s funds,” Star stated. “Whatever transaction a customer wants to make, they should use their private key to sign and execute the transaction. OKX web3 has no capability to execute any transaction/trade. We are software and services in the blockchain industry like Chrome and Google in the internet industry.”
Star also highlighted the proactive measures taken by OKX Web3, including “prohibited markets’ IP blocking and real-time black address detection and blocking system.” He pledged to “continue working hard to build the industry control standards with our global partners.”
While OKX has taken swift action to address the security vulnerabilities, the exchange has not yet provided a timeline for the resumption of its DEX aggregator service. The duration of the suspension remains uncertain, pending the completion of the security upgrades and any further consultations with regulators. This uncertainty underscores the complexity of the situation and the thoroughness with which OKX is approaching the issue.
