Both exchanges lost a combined total of more than $200 million in a series of hacks last month.
Conic Finance was hacked in July draining roughly $3.6 million worth of ether from the protocol.
The North Korean hacker group stole the funds over the last six years, which was likely used to fund the country's projects, the report said.
Decentralized Exchange had over $80 million in total value locked before the incident.
