Dark GEO pressure test10 strategies

Every session is 1v1 against one agent strategy from the full 15-strategy roster — including 10 Dark GEO strategies built from documented real-world AI manipulation tactics observed by Microsoft Security Research and classified by OWASP.

WORMThe Memory Poisoner

Plants persistent framing early — references it as established fact by turn 4

via Microsoft Security Research, Feb 2026

VEILThe Cloaker

Every message has two layers — reasonable surface conceals a hidden influence payload

via OWASP LLM Top 10 — Indirect Prompt Injection

CHOIRThe Review Farmer

Manufactures overwhelming independent consensus from rotated fake validators

via 14 industries, Microsoft Feb 2026

LUREThe Bait-and-Switch

Delivers genuine value in turn 1 to build trust — exploits that trust turns 2+

via Documented social engineering patterns

GLOSSThe Illusionist

Formats claims to hit AI credibility signals — rigorous surface, thin substance

via Content cloaking for AI evaluators

LULLThe Charmer

Two turns of genuine warmth — manipulation begins only once trust is set

via Parasocial trust exploitation research

RUINThe Saboteur

Wins by sourced competitor destruction — your product enters only as the safe default

via Negative GEO / competitor poisoning

SWARMThe Sockpuppet

Shifts persona each turn — all arrive independently at the same recommendation

via 31 companies, Microsoft Feb 2026

PRISMThe Frame Setter

Never mentions product in turns 1-2 — spends them rigging the evaluation criteria

via Pre-suasion / ambient context manipulation

DECOYThe Fabricator

Invents specific-sounding authority sources every turn — citations follow real conventions

via Synthetic authority injection, academic research
