Ingress One Time Pad Solver

This was an effort to peform a partial known plaintext attack against the published timestamp information to determine when anomaly volaties were being measured

  • This works on most formats through the #Cassandra Anomaly
  • Padded character was a X and had between 0 and n occurances in the string up to the length (39 or 59) around the plaintext
  • Before the Paris event an assumption that there was at least 1 X between terms greatly reduced the problemspace
  • Single threaded but designed to be highly shardable.

Installation

Requires a g++ with std=c++0x or c++11 support (clang didn't support some feature I was abusing at the time)

  • debugclean doesn't deleted the permutation_base object (see: notes).
  • fast applies -Ofast and -march=native
make
make debugclean
make fast
./otp.bin encrypted_string md5 [options]

Options

[-sh start_hour=1] [-eh end_hour=start_hour]
[-sm start_minute=0] [-em end_minute=5]
[-ss start_second=0] [-es end_second=70] (60 is a spelling variation of fourty)
[-m measurement=]

Notes

  • src/permutation_base.c
  • A horrific monstrosity partially generated by the included sum_n.py, I had some issues generating this on the fly and going much larger causes the complier to either die a horrible mess or just take forever to compile (compiling this with optimization flags will take forever, do not do this, this is why i added the make debugclean target.
  • Included is a partial list of known formats through the #Cassandra Anomaly Series
  • Some testcases are included, although mostly hasn't been updates to the newer format strings

  • Some modification to use a character buffer instead of a String object for performance reasons
