Yellow Teams Bring AI Offense and Defense Into One Security Function

Yellow Teams Bring AI Offense and Defense Into One Security Function

FIRST LOOK ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 5.5 Dark Reading

Yellow teams are an emerging security practice in which engineers build both offensive and defensive AI tools to stress-test AI capabilities and expose vulnerabilities before adversaries do. This dual-role model compresses the feedback loop between red and blue functions, but it also concentrates privileged knowledge of exploitable AI weaknesses in a small group with broad system access. Defenders should assess the insider-risk and knowledge-management implications of consolidating offensive AI tooling within a single team.

Amazon Bedrock Prompt Injection Traverses Agent Hierarchies

Amazon Bedrock Prompt Injection Traverses Agent Hierarchies

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.5 Palo Alto Unit 42

Unit 42 researchers conducted red-team analysis of Amazon Bedrock's multi-agent collaboration framework, demonstrating how attackers can systematically exploit prompt injection to traverse agent hierarchies, extract system instructions, and invoke tools with attacker-controlled inputs. The research reveals that multi-agent architectures introduce compounded attack surfaces through inter-agent communication channels, though no underlying Bedrock vulnerabilities were identified. Properly configured Guardrails and pre-processing stages effectively mitigate the demonstrated attack chains.
