### DomainKeys Identified Mail (DKIM)
You must **configure a DKIM for the new domain**. If you don't know what is a DMARC record [**read this page**](../../network-services-pentesting/pentesting-smtp/#dkim).
This tutorial is based on: [https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy](https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy)
{% hint style="info" %}
You need to concatenate both B64 values that the DKIM key generates:
```
v=DKIM1; h=sha256; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA0wPibdqPtzYk81njjQCrChIcHzxOp8a1wjbsoNtka2X9QXCZs+iXkvw++QsWDtdYu3q0Ofnr0Yd/TmG/Y2bBGoEgeE+YTUG2aEgw8Xx42NLJq2D1pB2lRQPW4IxefROnXu5HfKSm7dyzML1gZ1U0pR5X4IZCH0wOPhIq326QjxJZm79E1nTh3xj" "Y9N/Dt3+fVnIbMupzXE216TdFuifKM6Tl6O/axNsbswMS1TH812euno8xRpsdXJzFlB9q3VbMkVWig4P538mHolGzudEBg563vv66U8D7uuzGYxYT4WS8NVm3QBMg0QKPWZaKp+bADLkOSB9J2nUpk4Aj9KB5swIDAQAB
```
{% endhint %}
### Test your email configuration score
You can do that using [https://www.mail-tester.com/](https://www.mail-tester.com)\
Just access the page and send an email to the address they give you:
```bash
echo "This is the body of the email" | mail -s "This is the subject line" test-iimosa79z@srv1.mail-tester.com
```
You can also c**heck your email configuration** sending an email to `check-auth@verifier.port25.com` and **reading the response** (for this you will need to **open** port **25** and see the response in the file _/var/mail/root_ if you send the email a as root).\
Check that you pass all the tests:
```bash
==========================================================
Summary of Results
==========================================================
SPF check: pass
DomainKeys check: neutral
DKIM check: pass
Sender-ID check: pass
SpamAssassin check: ham
```
Alternatively, you can send a **message to a Gmail address that you control**, **view** the received **email’s headers** in your Gmail inbox, `dkim=pass` should be present in the `Authentication-Results` header field.
```
Authentication-Results: mx.google.com;
spf=pass (google.com: domain of contact@example.com designates --- as permitted sender) smtp.mail=contact@example.com;
dkim=pass header.i=@example.com;
```
### Removing from Spamhouse Blacklist
The page www.mail-tester.com can indicate you if you your domain is being blocked by spamhouse. You can request your domain/IP to be removed at: [https://www.spamhaus.org/lookup/](https://www.spamhaus.org/lookup/)
### Removing from Microsoft Blacklist
You can request your domain/IP to be removed at [https://sender.office.com/](https://sender.office.com).
## Create & Launch GoPhish Campaign
### Sending Profile
* Set some **name to identify** the sender profile
* Decide from which account are you going to send the phishing emails. Suggestions: _noreply, support, servicedesk, salesforce..._
* You can leave blank the username and password, but make sure to check the Ignore Certificate Errors
 (1) (2) (1) (1) (2) (2) (3) (3) (5) (3) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1) (1).png>)
{% hint style="info" %}
It's recommended to use the "**Send Test Email**" functionality to test that everything is working.\
I would recommend to **send the test emails to 10min mails addresses** in order to avoid getting blacklisted making tests.
{% endhint %}
### Email Template
* Set some **name to identify** the template
* Then write a **subject** (nothing estrange, just something you could expect to read in a regular email)
* Make sure you have checked "**Add Tracking Image**"
* Write the **email template** (you can use variables like in the following example):
```markup
Dear {{.FirstName}} {{.LastName}},
As you may be aware, due to the large number of employees working from home, the "PLATFORM NAME" platform is being migrated to a new domain with an improved and more secure version. To finalize account migration, please use the following link to log into the new HR portal and move your account to the new site: "PLATFORM NAME" login portal
Please Note: We require all users to move their accounts by 04/01/2021. Failure to confirm account migration may prevent you from logging into the application after the migration process is complete.
Regards,
WRITE HERE SOME SIGNATURE OF SOMEONE FROM THE COMPANY
{{.Tracker}}
```
Note that **in order to increase the credibility of the email**, it's recommended to use some signature from an email from the client. Suggestions:
* Send an email to a **non existent address** and check if the response has any signature.
* Search for **public emails** like info@ex.com or press@ex.com or public@ex.com and send them an email and wait for the response.
* Try to contact **some valid discovered** email and wait for the response

{% hint style="info" %}
The Email Template also allows to **attach files to send**. If you would also like to steal NTLM challenges using some specially crafted files/documents [read this page](../../windows-hardening/ntlm/places-to-steal-ntlm-creds.md).
{% endhint %}
### Landing Page
* Write a **name**
* **Write the HTML code** of the web page. Note that you can **import** web pages.
* Mark **Capture Submitted Data** and **Capture Passwords**
* Set a **redirection**
.png>)
{% hint style="info" %}
Usually you will need to modify the HTML code of the page and make some tests in local (maybe using some Apache server) **until you like the results.** Then, write that HTML code in the box.\
Note that if you need to **use some static resources** for the HTML (maybe some CSS and JS pages) you can save them in _**/opt/gophish/static/endpoint**_ and then access them from _**/static/\**_
{% endhint %}
{% hint style="info" %}
For the redirection you could **redirect the users to the legit main web page** of the victim, or redirect them to _/static/migration.html_ for example, put some **spinning wheel (**[**https://loading.io/**](https://loading.io)**) for 5 seconds and then indicate that the process was successful**.
{% endhint %}
### Users & Groups
* Set a name
* **Import the data** (note that in order to use the template for the example you need the firstname, last name and email address of each user)
.png>)
### Campaign
Finally, create a campaign selecting a name, the email template, the landing page, the URL, the sending profile and the group. Note that the URL will be the link sent to the victims
Note that the **Sending Profile allow to send a test email to see how will the final phishing email looks like**:
.png>)
{% hint style="info" %}
I would recommend to **send the test emails to 10min mails addresses** in order to avoid getting blacklisted making tests.
{% endhint %}
Once everything is ready, just launch the campaign!
## Website Cloning
If for any reason you want to clone the website check the following page:
{% content-ref url="clone-a-website.md" %}
[clone-a-website.md](clone-a-website.md)
{% endcontent-ref %}
## Backdoored Documents & Files
In some phishing assessments (mainly for Red Teams) you will want to also **send files containing some kind of backdoor** (maybe a C2 or maybe just something that will trigger an authentication).\
Check out the following page for some examples:
{% content-ref url="phishing-documents.md" %}
[phishing-documents.md](phishing-documents.md)
{% endcontent-ref %}
## Phishing MFA
### Via Proxy MitM
The previous attack is pretty clever as you are faking a real website and gathering the information set by the user. Unfortunately, if the user didn't put the correct password or if the application you faked is configured with 2FA, **this information won't allow you to impersonate the tricked user**.
This is where tools like [**evilginx2**](https://github.com/kgretzky/evilginx2) or [**CredSniper**](https://github.com/ustayready/CredSniper) are useful. This tool will allow you to generate a MitM like attack. Basically, the attacks works in the following way:
1. You **impersonate the login** form of the real webpage.
2. The user **send** his **credentials** to your fake page and the tool send those to the real webpage, **checking if the credentials work**.
3. If the account is configured with **2FA**, the MitM page will ask for it and once the **user introduces** it the tool will send it to the real web page.
4. Once the user is authenticated you (as attacker) will have **captured the credentials, the 2FA, the cookie and any information** of every interaction your while the tool is performing a MitM.
### Via VNC
What if instead of **sending the victim to a malicious page** with the same looks as the original one, you send him to a **VNC session with a browser connected to the real web page**? You will be able to see what he does, steal the password, the MFA used, the cookies...\
You can do this with [**EvilnVNC**](https://github.com/JoelGMSec/EvilnoVNC)
## Detecting the detection
Obviously one of the best ways to know if you have been busted is to **search your domain inside blacklists**. If it appears listed, somehow your domain was detected as suspicions.\
One easy way to check if you domain appears in any blacklist is to use [https://malwareworld.com/](https://malwareworld.com)
However, there are other ways to know if the victim is **actively looking for suspicions phishing activity in the wild** as explained in:
{% content-ref url="detecting-phising.md" %}
[detecting-phising.md](detecting-phising.md)
{% endcontent-ref %}
You can **buy a domain with a very similar name** to the victims domain **and/or generate a certificate** for a **subdomain** of a domain controlled by you **containing** the **keyword** of the victim's domain. If the **victim** perform any kind of **DNS or HTTP interaction** with them, you will know that **he is actively looking** for suspicious domains and you will need to be very stealth.
### Evaluate the phishing
Use [**Phishious** ](https://github.com/Rices/Phishious)to evaluate if your email is going to end in the spam folder or if it's going to be blocked or successful.
