OKX to restart DEX with anti-abuse upgrades after Lazarus ‘misuse’

Crypto exchange OKX has brought its decentralized exchange (DEX) aggregator back online with new security upgrades after it was paused in March to prevent further misuse by the North Korean hacking crew, the Lazarus Group.

OKX founder and CEO Star Xu said in a May 4 statement to X that the DEX aggregator, OKX Web3, will resume with several new features, including a “real-time abuse detecting and blocking system.”

A DEX aggregator is a service that pulls data from multiple decentralized exchanges and market makers and then presents it to users to assist with trading. Xu says, “OKX Web3 is a browser and search engine for blockchain.”

At the same time, OKX said in a May 4 statement that the latest upgrade includes other new security measures to identify suspicious or fraudulent onchain activity from hackers and other bad actors.

“Our dynamic database of suspect addresses blocks hackers and bad actors real-time, while proactive alerts warn you about risky transactions,” the exchange said.

“We’re audited and verified by leading blockchain security firms like CertiK, Hacken and SlowMist, and infrastructure tested through our bug bounty program.”

Another feature added to the onchain analysis tool categorizes wallet holders by identifying them as possible whales or snipers.
