Mozilla and Google blocked eight weak intermediate keys on October 17; those CAs issued no end-entity certificates, while about 30,000 others need migration.

eMudhra’s board approved a voluntary exit from the global SSL/TLS certificate business after weak private keys were found in eight intermediate CA certificates. Researcher Wayne showed control of the keys on October 17, and Mozilla recovered them, confirming flawed generation from a lack of randomness. Google and Mozilla blocked the affected TLS keys that day and moved to distrust emSign ECC Root CA – G3. The company says infrastructure was not compromised. CERT-In reported no confirmed malicious exploitation as of October 21.

Unconfirmed: CERT-In said confirmed malicious exploitation was not established as of October 21, and eMudhra says its infrastructure was not compromised.

Key facts
  • CERT-In said the affected P-384 private keys had values smaller than 256.
  • Six certificates supported TLS and two supported code signing.
  • eMudhra revoked the affected CA certificates within 14 hours of discovery.
  • Chrome’s root-store change was expected to reach devices on October 27.
  • Global SSL/TLS is about 1% of revenue; G1 RSA roots stay during the transition.

What to do
  1. 1.Update browsers and trust stores, and review certificate chains.
  2. 2.Replace affected certificates, including bundles in apps, containers, and devices.
  3. 3.Do not assume a browser update covers every system that stores certificates.
