Another day, another cyber threat. With DMARC policy a hot topic in cybersecurity, opportunist hackers in North Korea are making headlines as they exploit weak email security.
The U.S. government recently issued a strong warning about email phishing cybercrime, reinforcing the importance of robust cybersecurity. On May 2nd, 2024, agencies, including the FBI, the Department of State, and the National Security Agency (NSA), raised awareness of North Korean cybercriminals exploiting weak email security.
North Korean hackers have successfully launched widespread spear phishing attacks by taking advantage of weak or poorly configured Domain-based Message Authentication, Reporting, and Conformance (DMARC) policies.
Spear phishing attacks are targeted, sophisticated attacks aimed at individuals and organisations. Therefore, they can present as authentic and be challenging to detect as fake or malicious.
Whether impersonating a CEO or requesting urgent financial transfers, spear phishing aims to deceive recipients and fool them into revealing sensitive information or allowing access to private networks and devices.
So, what does a DMARC policy do?
A DMARC policy enhances email security by checking emails and confirming their authenticity based on the domain they came from.
The DMARC policy allows domain owners to set instructions for email receivers, allowing senders to choose whether to monitor, quarantine, or reject emails that fail authentication checks.
DMARC can seem like a complicated area of email safeguarding. In February 2024, Google changed its DMARC policy statement to "p=quarantine," meaning that emails failing to pass DMARC will automatically be sent to spam.
DMARC policies play a vital role in helping organisations reduce the risk of phishing attacks, highlighting potential threats, and giving insight into email authentication failure.
That said, the new policy means businesses need to proactively authenticate their email domain to avoid having their emails sent to spam by default.
Businesses must proactively protect their domain from spoofing and mitigate phishing attacks. Having an active and up-to-date DMARC policy for your business and setting it to 'reject' adds an essential layer of protection. However, for many, DMARC is a complex thing to navigate.
