Introduction

Existing reference-based phishing detectors:

• ❌ Rely on a limited reference list which cannot adapt to temporal (e.g. emerging cryptocurrency brands) and regional (e.g. local brands) interests
• ❌ Unable to address logo-less phishing webpages
• ❌ Use un-interactable benchmark datasets as the test environment

In this work, we propose a framework called DynaPhish, as a complementary module for all reference-based phishing detectors. Our contributions lie in three folds:

• ✅ We perform on-the-fly knowledge expansion of the reference list automatically. Meanwhile, we use the popularity-based validation mechanism to ensure the benignity of added reference.
• ✅ We are the first to introduce the behavioral intention, which makes phishing decisions via observing the suspicious behaviors during the login action
• ✅ We publish DynaPD, which includes 6K clean and live phishing kits that are safe and interactable. Download from here: DynaPD. Visit the online demo here: DynaPD Dataset Demo.

Framework

Project Structure

We include the knowledge expansion part in this repository.

|_ knowledge_expansion: Knowledge Expansion Module
  |_ brand_knowledge_online.py: Knowledge Expansion Class

Setup

Tested on Ubuntu, CUDA 11

1. Install the required packages by

conda create -n dynaphish python=3.10
conda activate dynaphish
pip install -r requirements.txt
pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 torchaudio==0.11.0 --extra-index-url https://download.pytorch.org/whl/cu113
pip install --no-build-isolation git+https://github.com/facebookresearch/detectron2.git
cd knowledge_expansion/phishintention
chmod +x setup.sh
./setup.sh

2. Create a google cloud service account, set the billing details

• Create a project, enable "Custom Search API", "Cloud Vision API"
• For "Custom Search API", get the API Key and Search Engine ID following this guide.
• Create a blank txt file in the directory knowledge_expansion/api_key.txt, copy and paste your API Key and Search Engine ID into the txt file like the following:

   [YOUR_API_KEY]
   [YOUR_SEARCH_ENGINE_ID]
  

• Create service account and create key follow this guide, save the JSON to knowledge_expansion/discoverylabel.json

  {
    "type": "service_account",
    "project_id": "PROJECT_ID",
    "private_key_id": "KEY_ID",
    "private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE_KEY\n-----END PRIVATE KEY-----\n",
    "client_email": "SERVICE_ACCOUNT_EMAIL",
    "client_id": "CLIENT_ID",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/SERVICE_ACCOUNT_EMAIL"
  }
  

3. Knowledge expansion

conda activate dynaphish
python knowledge_expansion/main.py --folder [folder_to_test, e.g. datasets/test_sites]
