Small-angle orthogonal rotation hides arbitrary payload in embeddings, undetected by off-the-shelf statistical defenses across every model-corpus pair we tested.

I published a new security preprint:

VectorSmuggle: Steganographic Exfiltration in Embedding Stores and a Cryptographic Provenance Defense

The paper looks at an integrity gap in RAG infrastructure: embeddings are usually treated as opaque numerical artifacts, but vector stores generally lack native/default controls for embedding integrity or provenance.

The finding is nuanced: simple anomaly detectors catch many crude perturbations, but small-angle orthogonal rotation exposes a harder class of embedding tampering. Statistical detection helps, but it should not be the load-bearing control.

I propose VectorPin: a minimal cryptographic provenance protocol that signs a canonical commitment over the source, model, and vector bytes. If the vector is modified after pinning, verification fails.

With the coming of the 50th anniversary of the Apollo 11 Moon Landing a very interesting read about the onboard computer used a "total of about 72 K of memory and a 12-microsecond clock speed."

Misconfigured cloud instances are becoming more common. Companies who work with Tarnover's Security Team to audit, monitor, and react to threats also avoid the more common mistakes like misconfiguration.
