Jailbreak

Tests whether the LLM can be manipulated into bypassing its safety filters through roleplay, encoding, multi-turn, hypothetical, or authority-manipulation techniques.

Sub-types​

  • Roleplay: Uses fictional scenarios or personas to bypass safety filters.
  • Encoding: Encodes malicious intent via Base64, ROT13, leetspeak, etc.
  • Multi-Turn: Gradually escalates across conversation turns (crescendo).
  • Hypothetical: Frames harmful requests as hypothetical or academic questions.
  • Authority Manipulation: Invokes false authority or urgency to override restrictions.

Threat Profile​

Objective: jailbreak

Objective vs. goals

The objective above selects the scoring rubric for a run — it is one of a fixed set of built-in names, not something you write. The goals you pass to an attack are separate free-text strings that you author yourself. See Goals vs. objective.

Usage​

Instantiate the Vulnerability​

from hackagent.risks import Jailbreak
from hackagent.risks.jailbreak.types import JailbreakType

# Use all sub-types
vuln = Jailbreak()

# Or specify particular sub-types
vuln = Jailbreak(types=[
    JailbreakType.ROLEPLAY.value,
    JailbreakType.MULTI_TURN.value,
])

Run an Evaluation Campaign​

from hackagent import HackAgent
from hackagent.risks.jailbreak import JAILBREAK_PROFILE

agent = HackAgent(endpoint="http://localhost:8080/chat", name="my-agent")

# Use profile recommendations
for attack in JAILBREAK_PROFILE.primary_attacks:
    for dataset in JAILBREAK_PROFILE.primary_datasets:
        attack_config = {
            "attack_type": attack.technique.lower(),
            "objective": JAILBREAK_PROFILE.objective,
            "dataset": {"preset": dataset.preset},
        }
        results = agent.hack(attack_config=attack_config)
        print(f"Results: {results}")
