From book 2:

We multiplied all the chapter numbers together to get 6469693230 (http://104.131.44.161/6469693230.html, you were here for that)
We waited for the timer, when it ended we got this:

```
Once so popular,
But Insecurity took him over,
Once he was broken,
Only the bad guys liked him,
Now we are all going old here,
This is a perfect fit.

SEEK AND YOU WILL BE FOUND
7879
```

That led us to MD5, a method of Hashing that used to be considered secure, but no longer is.
We took only the chapters that were ciphered, multiplied there numbers together, got 312455. We put that into MD5 and found an IRC channel with the same name.

The IRC channel's Topic was:
```
Every thousandth prime is the way, but don’t forget to do something useful. Trying is the road. 140 Characters is your hint.
```

We basically went through every thousandth prime converting it to base64 until we reached the 969 thousandth prime, which when converted to base64 is MTQ5NzE3NDE
That led us to this twitter account:
https://twitter.com/MTQ5NzE3NDE

There were tweeted a series of numbers, these corresponded with frequencies of the tones made when you press certain numbers on a telephone. We translated that to a phone number, which when called gave us this message:

```
Very well. Maybe you should make the insecure secure again. Find it in the Known Web and your journey continues
```

So we went back to the number we'd turned into MD5 (a now insecure form of hashing) and put it into a more secure form, SHA-256. That led us to another web page:

(At the time the link on 7879 was not there)
Then we got the tweet `Let s do the talking, then say our name`
We tried entering various numbers after calling the phone number, somebody found that pressing Pound (#) after it finished it's first message, gave a second message:

```
Time Machine, a  Firetruck, R2-D2, and of course the Apollo Lunar Module. 6 letters from this place are the next key
```

(At this point the link appeared on the web page, leading to an encrypted hex matrix)

All 4 of those things are things that have been put ontop of The Great Dome at MIT as pranks.
The Great Dome has the letters MCMXVI (1916 in roman numerals)
Those 6 letters were the encryption key to decrypt the Hex matrix from the link.

That gave us a passage from the bible, specifically Genesis 11:9

```
Therefore its name was called Babel, because there the LORD confused the language of the whole earth; and from there the LORD scattered them abroad over the face of the whole earth.
```

Then, whilst checking all of 7879's known accounts on websites for clues, we found a new post on github:

https://github.com/7879/11.9

And that's where we are now
