CanIBeSpoofed: The Free Email Spoofing Tool

Scan your SPF and DMARC records to detect if they're vulnerable to email spoofing. CanIBeSpoofed uses 14 distinct checks to determine if a domain is vulnerable and what the level of exposure is.

Analyze your email supply chain with our email spoofing tool

CanIBeSpoofed - Overview

Magnification tool

Email Spoofing Discovery

With our proprietary analysis engine, you can test and identify SPF & DMARC configurations that can facilitate email spoofing.

Deep-dive into the features of our email spoofing tool

CanIBeSpoofed - Features

Our email spoofing tool performs 14 different SPF and DMARC configuration checks to ensure that your domain is protected from email spoofing and spam.

Some of these checks include verifying that your domain has an SPF record in place, ensuring that the 'all' mechanism is set correctly, and checking for insecure DMARC policies. We also identify vulnerabilities such as non-existent sub-domain records and partial DMARC coverage. With our expert checks, you can be confident that your domain is fully protected against email attacks and will not be flagged as spam by email receivers.

Improve your email security protections with the proprietary techniques that our email spoofing tool uses to identify and analyze your email gateway, spam filter, and malware filter technologies.

We can detect vulnerabilities in these filtering technologies by analyzing bounce responses. We support a comprehensive list of technologies, including Cisco IronPort, Sophos PureMessage, Sophos ESA, Trustwave SEG, Exchange Antispam Protection, Exchange Online Protection, Proofpoint SEG, FireEye MX, FireEye ETP Cloud, Forcepoint SEG, Forcepoint Cloud, Trend Micro HES, Symantec MessageLabs, Mimecast SEG, Clearswift SEG, Google Mail Protection, Yahoo Mail Protection, and Barracuda Email Security.

Improve your email security with our recursive SPF record querying service. Our email spoofing tool identifies all email sender IP addresses by querying your SPF record and all its lookups. We also collate IP ownership information, providing a reliable mechanism to see who operates your downstream mail sender infrastructure.

Elevate your email security with our advanced email sender supply chain visualization capabilities. Our email spoofing tool pulls near-exact geolocation information and presents it in both a tabular format and a world map visualization.

This valuable information helps you identify geolocation motivated risks, enabling you to make informed decisions. For example, if you're a Federal Government Agency, it's best to avoid using email infrastructure owned by a hostile nation's ISP and operated out of that nation.

Improve your email security with our comprehensive IP-driven blocklist identifier.

Our email spoofing tool identifies IPs associated with unsolicited bulk emails, spam operations, and spam services (i.e., Low Reputation Senders), snowshoe spam, which actively attempts to evade spam detection (i.e., Low Reputation Senders), hijacked endpoints infected by illegal third-party exploits, including open proxies (HTTP, socks, AnalogX, wingate, etc.), worms/viruses with built-in spam engines, and other types of trojan-horse exploits.

We also identify end-user (non-MTA) addresses that are dynamically allocated to residential users (i.e., Low Reputation Senders).

What is CanIBeSpoofed?

CanIBeSpoofed was the first tool that CanIPhish created, predating the Cloud Platform we offer today. It was built to provide businesses with not only an email spoofing tool but a single tool to understand the entire email landscape of a given domain.

CanIBeSpoofed does this by passively analyzing DNS records and actively interrogating email infrastructure to discover weaknesses that may expose a business to unnecessary risks.

CanIBeSpoofed is freely accessible, open-sourced on GitHub, and has deep integrations into the CanIPhish Cloud Platform. For example, if you need to see historical search data, then this can be viewed under your account dashboard. CanIPhish additionally maintains a view of every search performed and uses this for security research on the absence of security controls at scale.
