Rhea Finance and the Russia-linked Grinex exchange were hacked for a combined $21 million over the past two days.
At least 12 DeFi protocols and crypto businesses have been attacked in just over two weeks since the $280 million Drift Protocol exploit on April 1.
Attacks aimed at crypto protocols or companies since the start of April include CoW Swap, Hyperbridge, Bybit, Dango, Silo Finance, BSC TMM, Aethir, MONA, Zerion and, most recently, Rhea Finance and the Grinex exchange.
The Drift Protocol was hit with one of the largest exploits this year on April 1, losing around $280 million in a long-running social engineering attack suspected to involve North Korean-affiliated actors.
