Наверняка вы замечали, что в Python есть удобная функция для получения переменной окружения
os.getenv(NAME)
И её "сестра" для создания или изменения переменных окружения
os.putenv(NAME, VALUE)
Но почему-то putenv() не работает как должно. Энвайромент не обновляется!
os.putenv('MYVAR', '1')
print(os.getenv('MYVAR'))
... и ничего 😴
Почему так?
На самом деле энвайромент обновляется, но это значение не добавляется в словарь os.environ.
Откройте исходник функции os.getenv(). Это просто шорткат для os.environ.get()
В то время как putenv() это built-in С-функция.
Словарь os.environ (или точней класс из MutableMapping) создаётся из энвайромента в момент инициализации. Функция putenv() самостоятельно его не изменяет.
В тоже время, когда вы создаёте или изменяете ключ в os.environ, автоматически вызывается putenv() в методе __setitem__().
То есть, технически putenv() всё делает верно, но в os.environ это не отражается. Можно проверить так:
>>> os.putenv('MYVAR', '123')
>>> os.system('python -c "import os;print(os.getenv(\'MYVAR\'))"')
123
Я объявил переменную в текущем процессе и вызвал дочерний процесс, который её унаследовал и получил в составе os.environ.
Аналогично при удалении переменной вызывается еще одна built-in функция unsetenv(), удаляющая переменную из системы.
Итого
▫️ Удобней всего явно обновлять переменные через os.environ
▫️ Есть способ неявно создать/удалить переменную через putenv/unsetenv, что не повлияет на os.environ но изменит энвайромент и передаст изменения сабпроцессам. Но так лучше не делать!
▫️os.environ это просто обертка для built-in функций putenv() и unsetenv().

The attack used social engineering to mimic #WhatsApp. Meta is acting against an Italian firm linked to the spyware.

Alhamdulillah, I finished writing this book in few days.
I wrote this book to help my friends:
Nurkhankyzy Aiya, Acute myeloid leukemia (AML).
and all those children who are fighting for their lives.
Why is the book called that? AIYA MMD - means Attack and Introduction or (Android and IOS), start Your Adventure in Mobile Malware Development. also AIYA means AIYA Nurkhankyzy.
I will be very happy if this book helps at least one person to gain knowledge and learn the science of cybersecurity. The book is mostly practice oriented.
Of course the book is not as big as my previous works, this is because firstly I needed to urgently start a fundraising campaign for the Aiya and secondly many things remain confidential (NDA)
Mobile malware - it's a constantly evolving battlefield. What you learned here is just the beginning. Tools change, defenses adapt, but the mindset stays the same: think like the adversary to build stronger defenses.
This book is dedicated to my wife, Laura, and my children, Yerzhan and Munira. I would like to express my deep gratitude to my friends and colleagues.
Special thanks to #Russian#hacking#community, Medet Turin 2600.kz, BlackIce #hackerspace from Almaty (Kazakhstan) and my friends from Middle East countries: Kingdom of Bahrain, Kingdom of Saudi Arabia, UAE.
All examples are practical cases for educational and research purposes only.
