eMudhra Share Price Hits 20% Lower Circuit; Addresses Distrust of Global TLS Intermediate and Root CA

On October 21, 2026, eMudhra Limited issued a statement regarding the distrust of certain intermediate Certificate Authorities (CAs) in its global TLS business, as per the exchange filings.  

The company confirmed that its India DSC and eSign operations remain unaffected. 

Details of the Incident 

The issue involves 8 intermediate CAs from eMudhra's Global TLS business, created under its ECC root during a Key Generation Ceremony (KGC) on April 30, 2025. A flaw in the KGC led to the creation of weak keys, which were published to browser root stores.  

An independent researcher discovered that these weak keys could be reverse-engineered using AI-assisted techniques, leading to the distrust by major root programs like Apple, Google, Microsoft, and Mozilla. 

Infrastructure and Data Integrity 

eMudhra has confirmed that its infrastructure was not compromised, and no data breach occurred. All security controls, both physical and logical, remain intact. The incident does not affect eMudhra's India DSC and eSign businesses, as these operate on separate infrastructure from the global TLS business. 

Commercial Impact and Customer Support 

The affected global TLS business constitutes a small portion of eMudhra's operations, accounting for approximately 1% of the company's revenue. Despite the limited financial impact, there may be reputational risks.  

eMudhra is actively working with affected customers to provide replacement certificates and ensure uninterrupted services. The company is also collaborating with root programs and conducting a root-cause investigation.
