In recent developments within the cryptocurrency sphere, money laundering activities have once again come to light. Following previous maneuvers, Penpie Hacker successfully transferred 5,600 ETH (approximately $13,440,000) through the Tornado Cash platform. This action underscores the hacker's determination to utilize sophisticated techniques to evade tracking and regulation. It is noteworthy that last March, a hacker stole assets worth $197 million from Euler Finance, while the hacker mentioned in this context returned the stolen assets on April 4th. However, whether the commended hacker involved in this new development is connected to the past incident remains unclear as of now. These events have reignited public concerns regarding cryptocurrency security and compliance.
