Briefings

Eight intermediate TLS certificates issued by India-based eMudhra Limited were compromised, allowing anyone to mint trusted credentials for any site. As of late morning Tuesday, major browsers and apps blocked these keys, but the threat persists due to the difficulty of updating other Internet components like Linux distributions and IoT devices. An informal advisory from eMudhra stated 'We have a problem here - Wayne.'

Key points

• Eight intermediate TLS certificates issued by eMudhra Limited were compromised, enabling anyone to mint trusted credentials for any site on the Internet.
• Major browsers and apps blocked all eight compromised intermediate certificates as of late morning Tuesday, but the threat remains active due to the difficulty of updating other Internet components.

Context

This incident involves eight intermediate TLS certificates from eMudhra Limited, a certificate authority based in India. The compromised keys allow unauthorized sites to be trusted globally, requiring immediate action from major tech providers.

Limitations

No certificate transparency logs were available to track the issuance of these compromised keys. The threat is ongoing because updating other Internet components like Linux distributions and IoT devices is difficult and time-consuming.
