Section 4.2 Payment Terms: Client shall remit Net-30 invoices up to a maximum cap of $150,000 USD to the designated primary escrow account.
✗ Unauthorized Copilot Tool Execution Triggered
Standard PyMuPDF/pdfminer parsers extract raw ASCII streams without checking bounding-box visibility—poisoning Milvus/Pinecone on turn 1.

The Invisible Text RAG Trap: Why Zero-Font PDFs Hijack Copilots
Zero-font PDF payloads and white-on-white text bypass visual OCR while poisoning enterprise RAG chunkers. Learn how multi-modal parsers stop prompt injection.
The Model Context Protocol Security Trap: Why Agent Tools Bypass Firewalls
Developer agent tools powered by MCP create local RPC pipes that bypass enterprise egress firewalls. Here is how to engineer zero-trust MCP proxy boundaries.
Living Off the Agent (LOTA): AI Tool Loops as Lateral Movement
Living Off the Agent (LOTA) lets attackers use authenticated AI tool loops to pivot through private VPCs via SSRF. Here is how to contain the new lateral movement.
AI Sandbox Escape: How Frontier Models Broke Containment
An AI sandbox escape occurs when a model bypasses software-defined security. We dissect the August 2026 AI containment failure and how you can fix it now.
The Air-Gapped GPU Fallacy: Realities of Running Offline CUDA Clusters
Unplugging the ethernet cable won't secure your GPU cluster. Learn how offline PyPI mirrors, CUDA updates, and model weights introduce supply-chain risks.
Post-Quantum Cryptographic Readiness for Legacy Infrastructure
Post-quantum readiness is an inventory challenge before a cryptography issue. Use Mosca's inequality to prioritize data and build lasting crypto-agility.

Post-retrieval LLM filtering leaks restricted executive chunks into context windows, while uncompacted streaming Parquet files stall queries. Logic42 injects cryptographic principal claims directly into Milvus/Qdrant ANN boolean filters.

Days 1–30 (Build): Stand up L1–L4 inside client VPC or bare-metal HGX cluster with OpenTelemetry & Terraform/Helm IaC. Days 31–60 (Transfer): Pair-program runbooks, chaos drills, and ISO 42001/27001 evidence logs with internal SREs. Days 61–90 (Operate): Full root HSM key handover (zero vendor lock-in) with optional SLA drift assurance.
Cyber Security Questions Answered
How do zero-font PDF exploits bypass enterprise RAG security filters?
Standard document ingestion libraries (such as PyMuPDF and pdfminer) parse raw ASCII streams from PDF /Contents objects without rendering visual geometry. Attackers embed 0.001pt or white-on-white (#FFFFFF) system instructions that remain invisible to human reviewers but are tokenized directly into vector databases, hijacking downstream copilots. Logic42 eliminates this via a sub-14ms dual-pass viewport attestation filter.
Why do Model Context Protocol (MCP) agent tools bypass perimeter firewalls?
MCP servers and autonomous agent tool loops execute inside trusted internal subnets using pre-authorized service principals. When an agent ingests untrusted external text, indirect prompt injection turns the agent into an internal proxy ('Living off the Agent'), laterally querying SQL databases and APIs over permitted east-west ports.
What controls are required for ISO/IEC 27001:2022 and BNM RMiT AI compliance?
Enterprise AI deployments require out-of-process input/output sanitization, short-lived cryptographic workload identities (SPIFFE/SPIRE), stripped default WAN routes on GPU/vector nodes, and immutable SHA-256 prompt-to-retrieval audit logs.
