DMARC is a global standard for email authentication. It allows senders to verify that the email really comes from whom it claims to come from. This helps curb spam and phishing attacks, which are among the most prevalent cybercrimes of today. Gmail, Yahoo, and many other large email providers have implemented DMARC and praised its benefits in recent years.
If your company's domain name is bankofamerica.com, you do not want a cyber attacker to be able to send emails under that domain. This puts your brand reputation at risk and could potentially spread financial malware. The DMARC standard prevents this by checking whether emails are sent from an expected IP address or domain. It specifies how domains can be contacted if there are authentication or migration issues and provides forensic information so senders can monitor email traffic and quarantine suspicious emails.
What is a Phishing Attack?
Phishing is an attempt by cybercriminals to trick victims into giving away sensitive information such as credit card numbers and passwords via fake websites and bogus emails. Phishing is a form of social engineering. It is also one of the most common methods cybercriminals use to infiltrate businesses and compromise their sensitive data.
Domain spoofing is a precursor to most phishing attacks used to spoof emails. In this process, an attacker spoofs a legitimate email address or domain name and sends fake emails containing phishing links and ransomware to the company's clientele. The unsuspecting recipient believes the spoofed email is from a company they know and trust and ends up sharing their corporate or banking information with the attacker, thereby getting phished. This affects the reputation of businesses and leads to the loss of prospects and customers.
DMARC can help minimize direct-domain spoofing attempts, which indirectly also cuts down on phishing attacks perpetrated via spoofed company domains.
How to Identify a Phishing Email Sent from a Spoofed Domain?
Spoofing is not a new threat. Email spoofing is a deceptive tactic used by attackers to manipulate both the identity of the sender of an email message and the apparent origin of that message. Most spoofing attacks either use forged header information or create a fake sender email address.
Recipients can detect phishing emails sent from a spoofed company domain by examining the email header information, such as the "from:" address and "return-path" address, and verifying that they match. While the email "From" address is a visible header, the "return-path" address is usually not immediately visible, and upon inspecting, it can help receivers detect the original identity of the attacker.
For example:
A phishing email sent from a spoofed domain will most likely have its From: address as: marketing@company.com, which looks authentic to the untrained eye of the receiver who is familiar with the services of the said company. However, on inspecting the Return-path address, the receiver will realize that the email is not from where the sender claims it to be,
Domain owners can also detect and identify domain spoofing and impersonation attempts by deploying a DMARC report analyzer at their organization. PowerDMARC's DMARC report analyzer allows domain owners to:
- Receive and read their DMARC reports on a well-organized dashboard, across a single pane of glass, instead of having to read individual reports sent to them on their email or web server.
- Organizations' DMARC data is organized and assorted into convenient viewing formats such as per result, per sending source, per country, per organization, detailed stats, and geolocation.
- Difficult-to-read XML files containing DMARC aggregate data is parsed into simpler and easily readable documents.
- Domain owners can export the data in the form of scheduled PDF reports to share with employees for awareness and inspection.
- Forensic information on malicious sending sources providing granular details on the origin and location of these forged addresses so they can be easily reported and taken down.
How to Reduce Email Phishing with DMARC?
A DMARC policy mode of p=reject can be an effective solution in combating a wide range of cyberattacks, including direct-domain spoofing and email phishing.
DMARC helps verify the origin of emails and block out fake emails from being received and opened. However, in reality, a limited number of businesses have actually adopted the protocol, and an even smaller population has implemented it correctly.
PowerDMARC's DMARC analyzer aids organizations in achieving DMARC enforcement the right way! While a DMARC reject policy, when taken lightly, can lead to the loss of legitimate emails, hosted DMARC services ensure improvement in email deliverability and reduced email phishing attacks over a period of time.
PowerDMARC's DMARC analyzer helps organizations safely upgrade their DMARC policy from monitoring only to p=reject, so they can enjoy the benefits of email authentication without worrying about the consequences.
Additionally, when you are on p=reject, you can avail of the benefits of visual identification with BIMI, by attaching your unique brand logo to specific outgoing emails that reach your clients.
