# [Mailfoguess](https://github.com/WildSiphon/Mailfoguess)

**OSINT tool** to **guess** and **verify** (experimental) the **email address of a person** from  information such as firstname, middlename, lastname, username...

## <img src="https://github.githubassets.com/images/icons/emoji/unicode/1f4a1.png" alt="bulb" style="zoom:33%;" /> The script

### Operation

An email address is made up from **local-part**, the symbol **@**, and a **domain**. This script does :

- **Create *a lot* of possible local-part** from informations given and following generation level 
- **Add @domain to all local-part** respecting the conditions of creation of mail of these domains
- Optional: **Verify these mails** (only for "gmail","laposte","protonmail","yahoo")

**WARNING: Mailfoguess uses [holehe](https://github.com/megadose/holehe) to verify the generated mails. It can lead to false results due to rate limit or else.**

python script to guess the potentials email adress of someone

optional arguments:
  -h, --help            show this help message and exit

Target:

Output:
  Select how the data will be displayed and/or saved

--print, -P           print generated informations on screen (local-part, emails and verified emails)
  --output [OUTPUT_LOCATION], -O [OUTPUT_LOCATION]
                        choose output location (default is "./output")
  --nb-localparts [NB_PRINT_LOCALPARTS]
                        set the maximum of local-part printed when informations are displayed (default is 20)
  --nb-emails [NB_PRINT_EMAILS]
                        set the maximum of emails printed per domain when informations are displayed (default is 4)
  --nb-verified [NB_PRINT_VERIFIED]
                        set the maximum of verified emails printed per domain when informations are displayed (default is all)
```

### No interactions mod

You enter the *No interactions mod* when you specify the parameters in the command line.

#### EXAMPLE

```bash
~$ python3 mailfoguess.py -f Pierre -l Croce --print --yes
```

![demo](https://raw.githubusercontent.com/WildSiphon/Mailfoguess/main/assets/demo.gif)

### Interactions mod

You enter *Interactions mod* when no indication are provided to generate potentials emails.

#### EXAMPLE

```bash
$ python3 mailfoguess.py
$ python3 mailfoguess.py --level high
$ python3 mailfoguess.py --yes
```

![interactions_mod](https://raw.githubusercontent.com/WildSiphon/Mailfoguess/main/assets/interactions_mod.png)

You will get the same result after this part.

### Caution

Generating email address is very fast but the verification part can last a long time. For example the command below, (a very bad realistic test case), took me almost 6 hours to verify the 10 000 email address generated from 2300 local-part.

```bash
~$ python3 mailfoguess.py -f Bill -m "The Gater" -l Gates -u billythekid -n 1955 --level max --yes
```

If the verification is to long for you, you can at any time press `[ctrl+c]` to stop the script. This will save all the data so you can resume the verification using the `–resume` or `-r` options.

Results are displayed in console, but everything is recorded and stored by default in `./output/` in a `json` file.

## <img src="https://github.githubassets.com/images/icons/emoji/unicode/1f39a.png" alt="level_slider" style="zoom:33%;" />Generation level

*Each level includes the previous ones.*

### Processing each part

Creating lists of names based on given informations:

| Level | Consequences |
| ----------- | ------------------------------------------------------------ |
| **Minimal** | Process with an *empty name* **If name is not composed**: - Process with *the name* **If name is composed**: - Process with *each part of the name separately* + Skipping *particles* (2 letters word) in all the names except in usernames - Process with *the all name separated by each separator* Example: Jean-Michel -> `"", jean, michel, jean-michel, jean.michel, jean_michel, jeanmichel` de Bauvoir -> `"", bauvoir, de-bauvoir, de.bauvoir, de_bauvoir, debauvoir` |
| **Low** | Process with the *vowelless lastname where all consecutives consonants are unique* Example: Cadillac -> `cdlc` |
| **High** | Process with the *vowelless lastname* Example: Cadillac -> `cdllc` |
| **Maximal** | |

### Generating local-part

| Minimal | Low | High | Maximal |
| :----------------------------------------------------------- | ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ |
| user first first ° last first ° lini first ° middle ° last first ° middle ° lini fini ° last fini ° middle ° last last | first ° middle first ° mini fini ° middle middle middle ° last middle ° lini last ° first last ° fini last ° middle last ° first ° middle last ° fini ° middle lini ° first ° middle lini ° first lini ° middle | first ° last ° middle first ° last ° mini first ° lini ° middle middle ° first middle ° fini mini ° first mini ° last last ° mini last ° middle ° first last ° mini ° first lini ° middle ° first | first ° mini ° last middle ° first ° last middle ° last ° first middle ° first ° lini middle ° lini ° first mini ° first ° last mini ° last ° first last ° first ° mini |

+ **first,middle,last,user** represents **firstname,middlename,lastname,username**
+ **fini,mini,lini** represents the initials of **f**irstname, **m**iddlename or **l**astname
  + If the name is composed, the initials are the concatenation of all initials' part
+ **°** represent a **separator** (by default they are `'', '-', '.', '_'`)

## <img src="https://github.githubassets.com/images/icons/emoji/unicode/1f4dd.png" alt="memo" style="zoom:33%;" /> Stuff to add

+ Colors in the printed output (feel free to help me with that)
+ ~~Creation of email~~
+ ~~Verification on email~~
+ Add options to change separators 
+ Add options to choose providers to use
+ Option to choose a country to define the list of domains
+ ~~Possibility to stop and resume the script~~
