PyPI Package Disguised as Instagram Growth Tool Harvests User Credentials
A deceptive PyPI package posing as an Instagram growth tool collects user credentials and sends them to third-party bot services.
This is generic support library for doing token-based authentication. You might use it to build a login system using bearer tokens, two-legged oauth, or MAC Access authentication.
Given a server-side master secret, you can serialize a dict of data into an opaque, unforgeable authentication token::
token = tokenlib.make_token({"userid": 42}, secret="I_LIKE_UNICORNS") print token eyJzYWx0IjogImY0NTU5NCIsICJleHBpcmVzIjogMTMyOTg3NTI2Ny4xNDQ5MzUsICJ1c2VyaWQiOiA0Mn0miXCe4NQQtXTE8NXSGcsL6dzSuQ==
Later, you can use the same secret to verify the token and extract the embedded data::
>>> data = tokenlib.parse_token(token, secret="I_LIKE_UNICORNS")
>>> print data
{u'userid': 42, u'expires': 1329875384.073159, u'salt': u'1c033f'}
Notice that the data includes an expiry time. If you try to parse an expired token, it will fail::
>>> # Use now=XXX to simulate a time in the future.
>>> tokenlib.parse_token(token, secret="I_LIKE_UNICORNS", now=9999999999)
Traceback (most recent call last):
...
ValueError: token has expired
Likewise, it will fail if the token was constructed with a non-matching secret key::
>>> tokenlib.parse_token(token, secret="I_HATE_UNICORNS")
Traceback (most recent call last):
...
ValueError: token has invalid signature
Each token also has an associated "token secret". This is a secret key that can be shared with the consumer of the token to enable authentication schemes such as MAC Access Authentication of Two-Legged OAuth::
>>> key = tokenlib.get_token_secret(token, secret="I_LIKE_UNICORNS")
>>> print key

For applications that are using the same settings over and over again, you will probably want to create a TokenManager object rather than using the module-level convenience functions::
>>> manager = tokenlib.TokenManager(secret="I_LIKE_UNICORNS")
>>> data = manager.parse_token(token)
>>> print data
{u'userid': 42, u'expires': 1329875384.073159, u'salt': u'1c033f'}
This will let you customize e.g. the token expiry timeout or hash module without repeating the settings in each call.
