DMARC is a worldwide standard for email authentication. It allows senders to verify that the email is from who it claims to be. This helps curb spam and phishing attacks, which are among the most prevalent cybercrimes today. Gmail, Yahoo, and many other major email providers have implemented DMARC and praised its benefits in recent years.
If your business domain name is bankofamerica.com, you don’t want a cyber attacker to be able to send emails under that domain. This puts your brand’s 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 in the event of 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 cyber criminals to trick victims into divulging sensitive information such as credit card numbers and passwords through fake websites and e-mails. Phishing is a form of social engineering. It is also one of the most common methods used by cyber criminals to infiltrate companies and compromise their sensitive data.
Domain spoofing is a precursor to most phishing attacks used to spoof email. In this process, an attacker spoofs a legitimate email address or domain name and sends fake emails containing phishing links and ransomware to corporate customers. The unsuspecting recipient thinks the spoofed email is from a company they know and trust and ends up sharing their business or banking information with the attacker, thus getting phished. This affects the reputation of businesses and results in the loss of leads and customers.
DMARC can help minimize direct domain spoofing attempts, which indirectly also reduces phishing attacks perpetrated through spoofed corporate domains.
How to identify a phishing email sent from a spoofed domain?
Identity theft 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 and the apparent origin of that message. Most identity theft attacks use forged header information or create a bogus sender email address.
Recipients can detect phishing emails sent from a spoofed corporate domain by examining the email header information, such as “from:” address and address. “Return path”, and checking that they match. While the “From” email address is a visible header, the “Return Path” address is usually not immediately visible and, upon inspection, can help recipients detect the. original identity of the attacker.
A phishing email sent from a spoofed domain will most likely have its From: address like: [email protected], which seems authentic to the untrained eye of the receiver who knows the services of the said company. However, by inspecting the return path address, the recipient will realize that the email is not from where the sender claims it came from,
Domain owners can also detect and identify domain spoofing and impersonation attempts by deploying a DMARC report analyzer in their organization. PowerDMARC DMARC Report Analyzer allows domain owners to:
- Receive and read their DMARC reports on a well-organized dashboard, all on one pane of glass, instead of having to read individual reports sent to them on their email or web server.
- DMARC data for organizations is organized and sorted in convenient viewing formats such as by result, by mailing source, by country, by organization, detailed statistics and geolocation.
- Hard-to-read XML files containing aggregated DMARC data are parsed into simpler, easily readable documents.
- Domain owners can export the data as scheduled PDF reports to share with employees for awareness and inspection.
- Forensic information on malicious sending sources providing granular details of the origin and location of these spoofed addresses so that they can be easily reported and removed.
How to reduce email phishing with DMARC?
A DMARC policy mode of p = reject can be an effective solution to combat a wide range of cyber attacks, including direct domain spoofing and email phishing.
DMARC makes it possible to verify the origin of e-mails and to block the reception and opening of fake e-mails. However, in reality, a limited number of companies have actually adopted the protocol, and an even smaller population has successfully implemented it.
PowerDMARC DMARC Analyzer helps organizations apply DMARC the right way! While a DMARC reject policy, when taken lightly, can result in the loss of legitimate emails, hosted DMARC services ensure improved email deliverability and reduced phishing attacks. by email over a period of time.
PowerDMARC’s DMARC Analyzer helps organizations securely upgrade their monitoring-only DMARC policy to p = reject, so they can enjoy the benefits of email authentication without worrying about the consequences.
In addition, when you are on p = reject, you can enjoy the benefits of visual identification with BIMI, by attaching your unique brand logo to specific outgoing emails that reach your customers.
