The default (or widely used) PRNG implemented by most popular languages is not cryptographically secure. Here is some collections of some predictors. Feel free to send PR if you have some predictors not in this repo.

If we have 624 output of mt19937, we could recover the whole state of mt19937.
Also, if we have 0, 1, 397 -th output of mt19937, we could predict the 624-th output of mt19937.
For PHP, if we have 0, 397 -th output of mt19937, we could recover the whole state of mt19937. See this post.
A predictor could be found in mt19937/predictor.py
Just like mt19937, but we only need 312 output of mt19937_64 to recover the whole state of mt19937_64.
Also, if we have 0, 1, 156 -th output of mt19937_64, we could predict the 312-th output of mt19937_64.
A predictor could be found in mt19937_64/predictor.py
