Hijacked .gh, .sl and .as registries handed attackers HTTPS certificates for Google domains

Attackers who hijacked the operators of three country-code domains obtained HTTPS certificates for Google domains, Google disclosed. The company says the issuing CAs did nothing wrong, so its defence came after issuance, and it cannot promise it found every affected domain.

GoodBarber serves on-device iOS web content from a fixed https origin through iOS 17's proxy API

GoodBarber now serves on-device web content in its iOS apps from https://secure.internal, through a WKWebsiteDataStore proxy API added in iOS 17. A fixed name gives the company's token issuer one origin to allowlist, where the old loopback server needed a wildcard that matched any port on the phone.

Under US Treasury sanctions, certificate authorities drop Russian and Iranian banks and state bodies

Russian banks moved to a state-run CA in August after GlobalSign mass-revoked its Russian customers' TLS certificates under May's US Treasury sanctions. Their customers now carry the problem, since Western browsers typically do not trust state-run CAs.

Cloudflare plans to become a public certificate authority and issue post-quantum Merkle Tree Certificates from early 2027. Sites it fronts will manage both kinds from one system, so the planning work falls on old devices that will never add a new root.

Porting OAuth2 Proxy to Gateway API moves the login redirect into a Traefik-specific CRD

A guide rebuilding browser OIDC login off ingress-nginx keeps its Gateway and HTTPRoute objects intact and hands the 401-to-302 step to two Traefik middlewares. Swap the controller and that half gets rewritten.

Configuration closes two of the three plaintext hops in "TLS everywhere"

The ingress-to-pod hop needs one nginx annotation and a pod that can serve TLS; the database hop needs one client flag. Pod-to-pod is the hop the dev.to inventory can only close with a mesh, and that is where the money goes.

An attacker hijacked Hetzner routing for 33 hours to push malicious Virtualizor updates

The hijacker forged Hetzner as the origin so origin validation passed, held the prefix from Friday night into Sunday morning, and Softaculous has no logs of any of it because none of the diverted traffic reached its servers.

nginx quietly skips OCSP stapling until a resolver appears in scope

The dangerous nginx bugs are the ones that emit no runtime signal at all, so the only artefact carrying the evidence is the config text itself. Stapling with no resolver in scope is the cleanest case of the class.
