Summary

Wayne Exposes Weak Keys

Independent researcher Wayne uncovered weak cryptographic keys, possibly using AI-assisted techniques.
The weak keys originated from a key-generation ceremony on 30 April 2025 that produced an extra key set.
Two security audits missed the flaw, raising questions about auditor effectiveness.
CERT-In issued mitigation guidance, forming a team to probe the root cause.
State Bank of India said 3,897 customer records appeared on the dark web on October 21.

History

Historical Context

After the 2011 DigiNotar breach—where attackers issued over 531,000 fake certificates, prompting Google, Mozilla, Apple and Microsoft to revoke its root—global regulators tightened CA audits. That legacy shaped today’s CERT-In probe of eMudra’s April 30 2025 key-generation flaw, which produced eight weak intermediate certificates and triggered browser blocks and a 20% BSE plunge.
