Rhea Finance

In April, $805 million was lost through DeFi hacks targeting platforms like Kelp Dao, Drift Protocol, and Grinex. Attacks involved methods such as social engineering and domain hijacking, with North Korea-backed Lazarus Group suspected as the primary threat actor.

Rhea Finance's post-mortem report revealed exploit losses of $18.4 million, more than double initial estimates. The attacker used a 'deliberately constructed swap route' to open numerous margin trading positions.

At least a dozen crypto entities have been attacked since the Drift Protocol hack, with Rhea Finance and the Russia-linked Grinex exchange recently targeted in attacks totaling $21 million.
