Control is Key: Guard Your Access

Hackers exploited a flaw in SkyMavis's decentralized control by identifying a fifth validating computer that was temporarily accessible due to an oversight in access management. SkyMavis had outsourced five of its nine validating computers, losing direct control, which created a vulnerability. The hackers recognized this weakness and capitalized on the access to execute their plan, demonstrating the critical importance of maintaining strict control and oversight in security systems to prevent unauthorized access.
