🟡 SIMULATED SCENARIO / THREAT MODEL

Is it possible to analyze Corporate Espionage without triggering the target's WAF/IDS? (Case Study 8)

When LATAM Expansion Teams deploy AI-driven market analytics, they become prime targets for corporate espionage. Adversaries use TCP fragmentation and HTTP request smuggling to bypass WAF/IDS, extracting proprietary models. Under the EU AI Act (Regulation (EU) 2024/1689, Article 9), organizations must guarantee the integrity and security of high-risk AI systems. But how do we prove the breach in a court of law without exposing the raw PII captured during the exfiltration?

Forensic Proof: The Tribunal de CPUs

To establish legal standing, we cannot rely on standard SIEM alerts, as the IDS was evaded. The evasion introduced a 45ms latency spike and exploited a CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N vulnerability in the reassembly engine. Instead, we utilize the Tribunal de CPUs, a Certus Engine construct that validates hardware-level execution states via secure enclaves. By analyzing the CPU cache side-channels, we can reconstruct the exact memory pages accessed by the espionage payload.

| Artifact Type | Technical Signature | Legal Admissibility | |---|---|---| | Memory Dump | SHA-256 Hash | High (Chain of Custody) | | Network PCAP | TCP Fragment Overlap | Medium (Requires Context) | | Enclave Log | Tribunal de CPUs Attestation | Absolute |

Extracting Evidence with PII-Zero

During forensic extraction, the PII-Zero protocol ensures that no personally identifiable data is exposed to the legal discovery team. PII-Zero applies deterministic tokenization at the memory page level before the hash is generated for the Tribunal.

import hashlib
# PII-Zero deterministic masking before hashing
def generate_forensic_hash(memory_page):
    masked_page = pii_zero_mask(memory_page)
    return hashlib.sha256(masked_page).hexdigest()

Suricata Evasion Signatures

The adversary used Suricata SID 2800001 evasion techniques, specifically manipulating TCP segmentation offsets to hide the payload boundary.

# Extracting fragmented packets from PCAP
tcpdump -r espionage_capture.pcap 'tcp[tcpflags] & (tcp-push) != 0' -w fragments.pcap

Conclusão

Proving corporate espionage without triggering IDS requires shifting the forensic paradigm from network perimeter logs to hardware-level attestation via the Tribunal de CPUs, ensuring EU AI Act compliance while preserving data sovereignty through PII-Zero.
