Frequently Asked Questions... with answers!

What is emailSpoofTest.com and what is it used for?

EmailSpoofTest.com is the only safe, easy, and private email self-penetration testing platform with tools needed to test and validate the security of any email system.

The concept: is to send yourself phishing & fraud emails using all the possible ways hackers can fake email; to test if an email system will drop the fraud email or allow fraud email in. If you get any of the clearly marked test emails, there are instructions inside with hints on how to correct the configuration.

 

Why is there a need for emailSpoofTest.com?

We found that even the advanced and carefully configured email security systems have security controls that are misconfigured or simply do not work

Ransomware is initialized by email fraud

Penetration tests are complicated, expensive, and exposes flaws to a 3rd party

DNS can expire and change -DNS is often changed by multiple groups within a company causing email security holes that go unnoticed without testing. Also, DNS can expire, changing your environment leaving exposure.


Cloud email changes -IP changes, DNS changes, gateway changes… we find that cloud email environments with shared IP spaces like Gsuite or M365 need the most work out of the box and require ongoing security control validation
Email security & detection mechanisms are dynamic and change constantly -this means you need to be checking for the latest BEC and phish-kit attacks often

Email Definitions
 
Email 1 is a clean passing email from emailspooftest.com.

Email 2 is from a disallowed subdomain of emailspooftest.com. You should not get email 0a.
Severity: Critical

DNS settings for emailSpoofTest.com

DMARC = Quarantine | Relaxed SPF | Relaxed DKIM  [v=DMARC1; p=quarantine; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=r; aspf=s; sp=reject] SPF = Allow MX, deny others  [v=spf1 mx include:secureserver.net -all] DKIM = email not signed [selector = a1, v=DKIM1; k=rsa; p=ZW1...]

*common scenario for businesses that are using all anti-fraud measures
Fix: set your inbound email inspection servers to check DMARC for subdomains

Email 3 is from badDMARC.com and checks if DMARC, SPF, and DKIM protections are protecting you from emails that impersonate the most secure firms like banks or governments. 

Email 4 is from a subdomain of badDMARC.com.

BadDMARC.com email test simulates spoofing a domain fully leveraging anti-fraud protection; strict SPF, strict DKIM, requiring DMARC alignemnt. If SPF, DKIM, and DMARC protections are working on your mail servers this email should not get to your inbox or spam.
Severity: Critical

DNS settings for badDMARC.com

DMARC = Reject | Strict SPF | Strict DKIM  [v=DMARC1; p=reject; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=s; aspf=s; sp=reject] SPF = Deny all senders  [v=spf1 -all] DKIM = email not signed [selector = default, v=DKIM1; k=rsa; p=MIIB...]

*common scenario for businesses that are using all anti-fraud measures

Fix: Turn on DMARC alignment controls for your inbound email inspection gateways.

 

Email E5 is from badDKIM.com and checks DKIM enforcement to simulate spoofing an email that only relies on DMARC alignment of DKIM for anti-fraud. If DKIM and DMARC protections are enforced (required in high security environments) this email should not get to your inbox or spam. Use this to test email security policy by adding this to your "Force DKIM" policy. 

Email E6 is from a subdomain of badDKIM.com.
Severity: Moderate

DNS settings for badDKIM.com

DMARC = Reject | Relaxed SPF | Strict DKIM [v=DMARC1; p=reject; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=s; aspf=r; sp=reject] SPF = Not configured (Neutral) DKIM = email not signed (Selector = default) [selector = default, v=DKIM1; k=rsa; p=MIIB...]

*common scenario for businesses that cannot implement SPF due to email complexity

Fix: On your inbound email inspection gateways set DMARC alignment for DKIM restrictions to deny email without a DKIM signature for domains that require DKIM via DMARC.

 

Email 7 is from badSPF.com which simulates spoofing an email from a disallowed mail server. If SPF protections are working properly this email should not get to your inbox or spam.

Email E8 is a subdomain of badSPF.com.
Severity: High

DNS settings for badSPF.com

DMARC = None | Strict SPF | Relaxed DKIM [v=DMARC1; p=none; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=r; aspf=s; sp=reject] SPF = Reject all [v=spf1 -all] DKIM = email not signed (Selector = default) selector = default, v=DKIM1; k=rsa; p=MIIB...]

*common scenario for businesses that cannot implement DKIM on every email or only have SPF configured

Fix: Set your email inspection gateways to reject email from servers that fail SPF checks. In some systems the setting may be enabled but the emails are not rejected, in about %40 of the inspection gateways we notice you may need to toggle the setting to get it to work. Always test security!

 

Email E9 tests spoofing internal mail from the outside. It sends a mail from you to you but from our servers. If internal authentication is properly set this email should not get to your inbox. 
Severity: Critical

Fix: On your inbound email gateways, only allow specific IP addresses to send mail from internal domains. This is typically a "relay" setting. 

Email E10 is sent from a non-existing domain "garbage000f.com". If this email gets to your inbox your email system does not perform reverse DNS lookups.
Severity: Critical

Fix: On your inbound email gateways,
enable DNS lookups. Tip: If you host your own gateways make sure you have enough resources, test first.
