TLDR
- Ripple confirmed it is sharing internal threat intelligence on North Korean operatives with crypto firms through Crypto ISAC.
- The company said attackers infiltrated firms by gaining employee trust rather than exploiting smart contract vulnerabilities.
- The Drift breach resulted in a $285 million loss after operatives deployed malware on trusted devices.
- The Kelp bridge exploit drained $292 million in ETH and was publicly attributed to the Lazarus Group.
- An attorney served restraining notices on Arbitrum DAO over 30,765 ETH linked to the Kelp exploit.
Ripple has begun sharing its internal intelligence on North Korean cyber actors with crypto companies. The company confirmed the move on Monday alongside Crypto ISAC. The decision follows two major exploits that drained over $500 million in April.
Ripple Expands Intelligence Sharing With Crypto ISAC
Ripple said it will provide Crypto ISAC with detailed profiles linked to North Korean operatives. The shared data includes LinkedIn accounts, email addresses, phone numbers, and location records. The company aims to help firms identify repeat infiltration attempts across the sector.
The strongest security posture in crypto is a shared one.
A threat actor who fails a background check at one company will apply to three more that same week. Without shared intelligence, every company starts from zero.

Crypto ISAC coordinates threat intelligence among digital asset companies. Ripple stated that attackers often apply to several firms within days. “A threat actor who fails a background check at one company will apply to three more that same week,” Ripple wrote on X.
The company said internal systems failed to detect the Drift breach because attackers already had trusted access. North Korean operatives reportedly built relationships with contributors for months. They then deployed malware and extracted private keys without triggering alarms.
Ripple and Crypto ISAC described the Drift case as a human infiltration operation. They said attackers did not exploit a smart contract flaw. Instead, they compromised employee devices and transferred $285 million once access was secured.
Industry data shows that DeFi exploits between 2022 and 2024 focused on code vulnerabilities. However, firms have tightened smart contract security in recent years. As a result, attackers shifted tactics from software flaws to social engineering campaigns.
Ripple said shared intelligence will allow companies to cross-check suspicious applicants. The company believes shared data can reduce repeated infiltration attempts. “The strongest security posture in crypto is a shared one,” Ripple posted.
Legal Disputes Follow April Exploits Linked to Lazarus Group
The April Drift breach and the Kelp bridge exploit both targeted ether assets. The Kelp exploit drained $292 million in ETH. Authorities publicly attributed both attacks to Lazarus Group operatives.
On Monday, an attorney for victims of North Korean terrorism served restraining notices on Arbitrum DAO. The filing claims that 30,765 ETH frozen after the Kelp exploit constitutes North Korean property. The attorney cited U.S. enforcement law in the submission.
Arbitrum DAO froze the ether following the exploit. However, lending platform Aave disputed the restraining notice. Aave argued in support of Arbitrum that stolen assets do not confer lawful ownership.
“A thief does not gain lawful ownership of stolen property simply by taking it,” Aave stated in its filing. The dispute now centers on whether frozen ETH can qualify as North Korean property. The combined April losses from Drift and Kelp exceed $500 million.
Ripple confirmed that it will continue supplying intelligence feeds to Crypto ISAC. The company said it will update member firms as new data emerges. Crypto ISAC did not disclose how many firms currently access the shared intelligence network.
