According to PeckShield, an unknown actor manipulated the price of the hWBTC token to drain the lending pool:
“The main reason is that the attacker sacrificed 200 WBTC to pump the exchange rate of hWBTC, so that even a tiny amount (2 Wei) could drain the current lending pools.”
The project team said they had contacted the hacker and were engaging with cybersecurity firms. According to the developers, they aim to reach an agreement with the attacker.
Further details about the incident were promised later.
Earlier, in March 2022, unknown attacked the Agave and Hundred Finance protocols. The total loss amounted to $11 million.
