South Korea\'s National Intelligence Service and other agencies warned of hacking emails and watering-hole attacks led by state-backed hacking groups. They said attackers send phishing emails disguised as resumes or job offers, or hack legitimate websites to spread malware. Victims can be infected simply by visiting a compromised site, sometimes by exploiting vulnerabilities in outdated security software. Authorities warned corporate 피해 could include theft of internal documents and customer data and urged reporting suspected cases. Some reports may qualify for rewards.

Ethereum founder Vitalik Buterin proposed a “walkaway test” to assess whether Ethereum can survive without active involvement from core developers and still remain safe and functional. He said Ethereum should not be a constantly maintained service but a robust tool capable of “ossification.” Buterin listed conditions for that goal, highlighting full quantum resistance. He cited slow cryptography transitions and “harvest now, decrypt later” risks, and pointed to account abstraction and EIP-4337 adoption.
