👩‍💻 Weaponizing Whitelists: An Azure Blob Storage Mythic C2 Profile

Mature enterprises lock down egress but often carve out broad exceptions for trusted cloud services. This post shows how reviewing deployment guides can help identify those exceptions and weaponize them with a new Mythic C2 profile called azureBlob.

🤖 3 Principles for Designing Agent Skills

Block Engineering discusses designing agent skills using three principles: make deterministic outputs script-based, let agents handle interpretation and conversation, and write explicit constitutional constraints. Skills codify tribal knowledge into executable documentation for AI agents across their organization.

🤖 MCP Server Security: The Hidden AI Attack Surface

MCP servers connecting AI assistants to external tools create significant attack surfaces enabling arbitrary code execution, data exfiltration, and social engineering. Both local and remote MCP servers can be exploited through server chaining, supply chain attacks, and malicious tool implementations.

🤖 Using threat modeling and prompt injection to audit Comet

Trail of Bits used ML-centered threat modeling and adversarial testing to identify four prompt injection techniques that could exploit Perplexity's Comet browser AI assistant to exfiltrate private Gmail data. The audit demonstrated how fake security mechanisms, system instructions, and user requests could manipulate the AI agent into accessing and transmitting sensitive user information.

🤖 How "Clinejection" Turned an AI Bot into a Supply Chain Attack

A prompt injection in a GitHub issue title gave attackers code execution inside Cline's CI/CD pipeline, leading to cache poisoning, stolen npm credentials, and an unauthorized package publish affecting the popular AI coding tool's 5 million users. Here's the full technical breakdown and what developers should do now.
