EMudhra Intermediate CA Compromise

Eight eMudhra intermediate CA certificates have been compromised, potentially allowing attackers to impersonate any website or service. Major browser and operating system providers (Mozilla, Microsoft, Apple, Chrome) have blocked the certificates since October 17-20, 2026, and users are advised to update their browsers and operating systems immediately. Developers should also update affected software packages including Go, Python certifi, Rust libraries, and Node.js to patch the vulnerability.
