  • Engineer — Learn: Researchers demonstrate 100% success rate for steganography-based indirect prompt injection against undefended MCP pipelines and propose a provenance-binding defense using HMAC labels and taint tracking — worth reading if you’re designing or reviewing agentic AI architectures today, but no active exploitation and no patch to apply.
  • SOC/IR — Learn: The attack class (steganographic trust laundering across agent boundaries) is novel and lacks any published IOCs, detection surface, or ATT&CK mapping yet — file for future detection work as MCP-based workflows become operationally common.
  • Leader — Skip
