# Find Cell

I lost my phone while I was travelling back to home but I was able to get back my eNB ID, MCC and MNC could you help me catch the tower it was last found. Note: decimal value upto 1 digit

So firstly, after seeing what they have said about the `eNB ID`, `MCC`, and `MNC`, I decided to look up what they meant, so :

* `eNB ID` : used to identify an EnodeB uniquely
* `MCC` : mobile country code
* `MNC` : mobile network code

You can distinguish which one is which by knowing that the `MCC` and `MNC` are both 3 digits so `81097` must be the `eNB ID`

We can use the `MCC` and `MNC` to find out that the cell tower is in the US, and that its provider is AT\&T. Now we need to triangulate the cell tower so after a bit of googling I found a website called cellmapper.net, where you can specify the `eNB ID`, `MNC` and `MCC`, so finally you get the latlong coordinates by clicking on the location, which are `32.8464489` and `-24.554806.`

### Flag:

Because we know that the briefing says the format is `darkCTF{latitude, longtitude}` to 1 decimal place we know that the flag is `DarkCTF{38.4, 24.5}`

The rounding is very odd
