The news of the security breach quickly circulated within the cryptocurrency community, sparking discussions on various platforms. Users began addressing the attack, with notable mentions on social media platforms indicating the severity of the incident. Data from analytics platform Whale Alert shed light on the magnitude of the breach, reporting a transfer of 4,502 Bitcoin valued at $308,948,771 USD from an undisclosed wallet to a new unknown destination.
