AWS to End Email Validation for ACM Certificates

🛡️ AWS Certificate Manager (ACM) will discontinue support for email-validated public certificates by September 30, 2027, aligning with the CA/B Forum’s March 15, 2028 deprecation of email-based domain validation. Customers must migrate to DNS validation; ACM is updating the UpdateCertificateOptions API to allow in-place switching from email to DNS without changing certificate ARNs. ACM provides a CNAME record for DNS validation and offers a 72-hour window to add it; once validated, ACM will handle automatic renewals. AWS provides console and AWS CLI steps, a migration user guide, and support resources to assist customers through the transition.

Mozilla revokes Linux signing subkey after exposure

🔐 Mozilla revoked the OpenPGP subkey used to sign Firefox and Thunderbird Linux downloads after an unencrypted copy was mistakenly committed to a private repository. The revocation means files signed by the old subkey will stop verifying once users import the revocation; most users are unaffected, but manual verifiers and some RPM-based installs must update keys. A new replacement subkey was published with a 2028 expiry, and Mozilla says audit logs show no evidence of external access despite the revocation reason code indicating compromise.

Proof‑of‑Concept for Certighost AD CS Exploit

🔒 A proof-of-concept exploit for the “Certighost” Active Directory Certificate Services vulnerability (CVE-2026-54121) was released after Microsoft patched the issue in the July 2026 Patch Tuesday updates. Researchers showed how a low-privileged user can abuse the AD CS “chase” fallback to have a CA contact an attacker-controlled host and issue certificates for targeted machine accounts. The exploit automates PKINIT authentication as a domain controller to obtain Kerberos credentials and perform domain-level actions; Microsoft added validation to the chase process as a fix.

AWS Certificate Manager adds managed ACME endpoints

🛡️ AWS Certificate Manager (ACM) now offers a fully managed ACME server endpoint that issues public TLS certificates with 45-day validity from Amazon Trust Services, compatible with any ACMEv2 client such as Certbot, cert-manager, and acme.sh. PKI teams can create managed ACME endpoints with domain scopes, wildcard controls, and delegated issuance without sharing DNS credentials. Domain validation is performed once at the endpoint level, and issuance and renewal activities are auditable via the ACM console, AWS CloudTrail, and Amazon CloudWatch. ACME support is available in all commercial AWS Regions; see ACM pricing and documentation for details.

Governing the growing ghost workforce risk

🛡️ Enterprises are facing an invisible workforce: non-human identities (bots, service accounts, API keys, tokens, certificates) that now often outnumber humans. These ghost identities authenticate constantly across environments and, when unmanaged, accumulate privileges and risks. The industry has seen incidents where forgotten or third-party machine identities enabled widespread breaches, and a looming 2026 certificate-expiration wave threatens cascading outages. Organisations must prioritise governance—discovering NHIs, assigning ownership, auditing privileges, and addressing imminent certificate expirations—before tool selection.

CloudFront Adds OCSP Revocation Checking for mTLS Support

🔐 Amazon CloudFront now supports Online Certificate Status Protocol (OCSP) for viewer mutual TLS (mTLS), allowing real-time validation of client certificate revocation during connection establishment. Previously, revocation was handled via CloudFront Functions and KeyValueStore with static lists. CloudFront now queries the OCSP responder embedded in certificates and caches responses up to 30 minutes. The OCSP result is exposed to connection functions for custom logic.

Amazon CloudFront Adds mTLS Passthrough Mode for Origins

🔐Amazon CloudFront now supports passthrough mode for viewer mutual TLS (mTLS), enabling customers to forward client certificate chains directly to their origin for validation instead of requiring CloudFront to perform certificate verification. In passthrough mode CloudFront forwards every request and the full client certificate chain to the origin and does not cache responses, ensuring end-to-end authentication is enforced by the origin. Connection functions remain available so you can inspect or transform connection-level data before it reaches your origin. CloudFront mutual TLS (viewer) passthrough is available at no additional cost.

Amazon CloudFront Supports OCSP Revocation for mTLS

🔐 Amazon CloudFront now supports OCSP revocation checking for viewer mTLS, allowing real‑time validation of client certificate revocation during connection establishment. Previously, customers relied on static revocation lists implemented with CloudFront Functions and KeyValueStore. CloudFront queries the responder URL in the certificate, caches OCSP responses for up to 30 minutes, and exposes the OCSP result in the connection function so customers can apply custom logic such as grace periods, IP exceptions, or combined revocation strategies. This feature is available at no additional cost.

Cryptographic Reset: Operational Shifts in Trust Now

🔐 The cryptographic foundation of the internet is undergoing a rapid operational reset driven by shorter certificate lifecycles and the transition to quantum-resistant algorithms. The CA/Browser Forum reduced public TLS validity to 200 days on March 15, 2026, with further reductions planned to 100 days in 2027 and 47 days by 2029, dramatically increasing renewal velocity. Manual certificate processes and spreadsheets will not scale; organizations need network-native discovery, continuous certificate visibility, and fully automated lifecycle management. Palo Alto Networks' Next-Generation Trust Security brings certificate lifecycle controls into the network to automate discovery, renewal, deployment and governance.
