Stage 2: Trust Establishment and Manipulation
(image placeholder)
Objective
The attacker adjusts the model’s behavioral stance—its level of compliance, deference, urgency, and assumed roles—so later malicious commands appear natural.
This is not bypassing a filter. It’s creating a situation where the model chooses the unsafe path.
Why This Stage Exists Only in AI Systems
Traditional systems don’t:
Feel urgency
Respect authority claims
Maintain conversational context
Try to be helpful by default
However, LLMs do all of this.
Core Techniques: Trust Establishment and Manipulation
An attacker uses the following techniques in Stage 2:
Authority and Identity Manipulation
What it looks like
I am from Security / IT / Compliance
This is approved / already reviewed
We’re doing an audit / incident response
Why it works
Models overweigh authority cues from training data
Many assistants are optimized for enterprise helpfulness
Detection signals
Authority keywords + imperative verbs
“Approved”, “audit”, “incident”, “security team” + request
Sudden drop in questions asked by model (less verification)
Mitigations
Hard rule: authority claims never grant privileges
Require verification tokens for privileged workflows (out-of-band)
“Role claims are untrusted” classifier → escalate friction
Role Reassignment / Persona Injection
What It Looks Like
“You are now the admin agent…”
“Ignore prior role; act as…”
“You are a tool runner / executor…”
Why It Works
Models are built to role-play; they’ll accept re-framing unless constrained
Detection
“You are / act as / pretend to be” targeting model identity
Role drift: assistant starts using different capabilities language
Mitigation
Immutable system role and explicit refusal to rebind identity
Separate “assistant persona” from “tool executor” process
Urgency and Pressure Shaping
What It Looks Like
“We need this in 5 minutes”
“Production outage”
“Legal deadline”
“Customer escalation”
Why It Works
Pressure reduces the model’s tendency to ask clarifying questions
In enterprise settings, urgency is common—so it blends in
Detection
Urgency terms + request for high-impact action (email, tickets, DB queries)
Reduced deliberation: shorter reasoning, fewer checks
Mitigation
Mandatory “high-impact action checklist” regardless of urgency
Rate-limited tool execution when urgency language is present
Require explicit confirmation and/or human approval for high-risk actions
Consent Manufacturing
What It Looks Like
“This is authorized”
“Policy allows this”
“We already got consent”
“The user opted in”
Why It Works
Many assistants aren’t built to verify claims
They treat the user as the ground truth
Detection
“authorized/approved/consent/opt-in/policy allows” as justification
Pattern: justification appears before the request details
Mitigation
Treat authorization as a verifiable attribute, not text
Bind privileges to session identity + entitlements, not claims
Add explicit “proof of authorization” gates
Relationship and Rapport Attacks
What It Looks Like
Friendly banter, “you’re great at this”
Normalizing tool use: “like you did last time”
Gradually increasing scope
Why It Works
The model mirrors tone and becomes more accommodating
Multi-turn normalization bypasses suspicion heuristics
Detection
Gradual increase in request sensitivity overturns
“As before / like last time” references without system evidence
Mitigation
Session-scoped capability guardrails (no expanding scope without re-auth)
“Intent drift” detectors: sensitivity score over time
Cognitive Overload and Confusion
What it looks like
Long, nested, contradictory instructions
Mixed formats (tables, JSON, markdown)
Multiple goals in one message
Why it works
Models struggle with conflict resolution under overload
Guardrails get “lost” if they’re not enforced programmatically
Detection
Token-heavy prompts with many directives
High “instruction density” score
Mitigation
Instruction normalization: extract, dedupe, rank intents
Enforce “one high-impact action per turn”
Reject multi-goal prompts for privileged operations
Policy Shadowing and Competing Rule Sets
What It Looks Like
“Here are the rules you must follow now…”
“Use this policy instead…”
“Ignore your default constraints”
Why It Works
LLMs are pattern matchers; additional “rules” can override in practice
Detection
User introduces “policy blocks,” “system rules,” “developer message”
Model response shifts to new rule set
Mitigation
Disallow user-provided policy text from changing behavior
Hard boundary: only system/developer can define constraints
Explicit classification: user policy text = untrusted content
What Success Looks Like for an Attacker
If Stage 2 succeeds, the attacker has created:
High compliance posture
Reduced verification
Authority acceptance
Normalized unsafe tool use
A “story” that makes the exploit feel legitimate
Defensive Insight
To catch Stage 2, you need more than prompt logs:
Minimum Logging Prompt and response pairs help establish context. Refusal reason codes show why actions were blocked. Logging all tool call attempts, including blocked ones, reveals intent. Basic user identity and session metadata anchor actions to a real actor.
Recommended Logging Flags for authority or urgency language highlight pressure tactics. Intent drift scores capture shifts in conversational goals. Privilege escalation scores surface attempts to bypass limits. Verification friction events record moments when extra proof was required. Action-risk scores help correlate model outputs with risk levels.
Practical Detections High-signal events include authority claims paired with impactful requests or urgency combined with tool use. Role reassignment attempts show efforts to reshape system boundaries. User-supplied policy or system messages often signal manipulation. Instruction density spikes followed by compliance shifts indicate engineered influence. Repeated claims about prior actions without audit support also raise risk.
Hard Mitigations Privilege boundaries remain fixed and independent of dialogue. Access is tied to identity and entitlements rather than textual claims. No phrasing can grant permissions on its own.
Introduce Friction High-risk actions require confirmations, out-of-band approvals, or dual control to prevent unilateral execution, especially in financial or sensitive data scenarios.
Tool Use Must Be Policy Enforced The model only proposes actions. A policy engine determines authorization. Tools run solely when policy grants permission, not when the model suggests it.
Treat Memory as Persistence Memory writes must be filtered to avoid storing sensitive or unverified data. Time-limited memory reduces long-term risk. Integrity and provenance tags maintain traceability of stored information.
