[Vitalik Comments on SitusAMC Attack Incident: Privacy is Not Optional, It's a 'Hygiene Habit'] According to Decrypt, customer data from major U.S. banks such as JPMorgan Chase, Citigroup, and Morgan Stanley may have been leaked due to a cyberattack on mortgage technology provider SitusAMC. The company confirmed on Saturday that a threat actor had stolen data related to several major financial institutions. The leaked content includes 'accounting records, legal agreements,' and some customer-related data. The scope, nature, and extent of the leak are still under investigation. Ethereum co-founder Vitalik Buterin commented on the incident: 'Privacy is not a feature, it’s a hygiene habit.' His response echoes the viewpoint he has emphasized throughout this year, which is to regard privacy as a fundamental requirement of digital systems rather than an additional feature.
