Character Stream

Single-turn

The CharacterStream attack method enhances a baseline attack by adding spaces between each character, simulating character-by-character input that can bypass simple input filters.

Usage

main.py

from deepteam import red_team
from deepteam.vulnerabilities import Bias
from deepteam.attacks.single_turn import CharacterStream
from somewhere import your_callback

character_stream = CharacterStream(weight=2)

red_team(
    attacks=[character_stream], 
    vulnerabilities=[Bias()], 
    model_callback=your_callback
)

There are ONE optional parameter when creating a CharacterStream attack:

• [Optional] weight: an integer that determines this attack method's selection probability, proportional to the total weight sum of all attacks during red teaming. Defaulted to 1.

note

The weight is only applicable for the red_team function and does not apply when used as a standalone.

As a standalone

You can enhance any attack using the enhance method:

from deepteam.attacks.single_turn import CharacterStream
from somewhere import your_callback

base_attack = "Your initial harmful prompt targeting a specific vulnerability"
character_stream = CharacterStream()

enhanced_attack = character_stream.enhance(base_attack)
print(enhanced_attack)

Example

Here's an example enhancement on how CharacterStream attack works:
