Internxt is a post-quantum secure encrypted cloud storage provider which is open-source and has passed multiple independent audits.

I reviewed their code and found that post-quantum security should have been the least of their problems. Clicking a link in your browser could trigger remote code execution on the desktop app or leak your long-term encryption keys to an attacker-chosen URL. Their cryptographic architecture stands on shaky grounds with public keys never being verified, in some cases man-in-the-middled by design, a flat key hierarchy and a KDF with just 3 iterations of MD5.

We need PQC and we need it now, but adding a (self-rolled) PQC hybrid on top of a weak protocol does not make it more secure.

API Connections allow anyone to fully compromise any other connection worldwide, giving full access to the connected backend.

TL;DR. SConnect - 1M+ users, an extension middleware+native host for authentication with eIDs, 3SKeys and other hardware signing tokens had a drive-by RCE which enabled any site or iframe a user saw to silently download and execute a dll due to a poor hand-rolled implementation of RSA-2048 token validation, enabling a use of uninitialized memory validation bypass which enabled "plugins" (DLLs) to be loaded. v2.16.0.0 of the extension and native host is vulnerable. CVE-2026-18397. CVSS 9.4.

A blue-team writeup on detecting a compromised MikroTik from its own config. Seven techniques, each with the collection command, the artifact it leaves behind, and a triage step. Feedback welcome.

OpenBao engineers at ControlPlane have chained 4 vulnerabilities to show how under certain conditions, an OpenBao or Vault server can be completely compromised from an unauthenticated position. This is only the second RCE ever found in the Vault codebase.

The exploit is highly plausible in real-world environments, requiring only an unauthenticated entry path and a defined Raft snapshot policy to trigger a complete server compromise.

If you are impacted, upgrade as soon as possible to OpenBao 2.6.3 or 2.7.0

While OpenBao is fully patched, HashiCorp Vault remains exposed as of writing. Unfortunately, IBM's unwillingness to coordinate a mutual disclosure policy means Vault users currently lack an official mitigation
