VectorSmuggle: Steganographic Exfiltration in Embedding Stores and a Cryptographic Provenance Defense
Steganographic exfiltration attacks succeed on embedding stores via retrieval-preserving perturbations such as small-angle orthogonal rotation, but an Ed25519-based provenance signature closes the attack class.
