Ransomware has become a commonplace threat faced by victims of industrial espionage and other cybercrimes. In the simplest terms, a ransomware encrypts all of a user’s data and demands payment in exchange for restoring access. Once the ransom is paid, the information is restored but with barriers raised around the encrypted data. This latter aspect is what makes DMARC such a effective defense mechanism. Unlike other anti-spyware solutions that rely on signatures or other technology to detect and block incoming attacks, DMARC employs a artificial intelligence powered and The inability to access your files and data after an attack makes traditional anti-virus products ineffective. Even the most sophisticated anti-virus programs can fail to detect subtle changes that could take you months to notice. In this post, we'll show you how we prevent data loss due to ransomware and identify the most effective DMARC protection with real-world results.

We'll also provide guidance on how to keep your business data safe even when it's not under the control of an effective anti-virus solution. If you’ve ever been inside of a cyber space, then you know the feeling of helplessness and frustration. You can’t do anything about it, and there isn’t much you can do about it unless you are willing to risk everything. If you are in a position where you could be affected by a cyber-attack, then it is in your best interest to take proactive measures. What that means is implementing measures like detecting when your computer is being used for online activity, and then blocking all access to that computer until it has been properly disinfected. Once that has happened, running the vehicle control software as well as disabling any signals that could help the infection occur can prevent further damage to your computer system and data.

The Role of DMARC in ransomware protection

There are some loitering misconceptions that DMARC is a matter of choice and has to do more with optional email compliance. That it’s fine even if you don’t implement DMARC. While DMARC can validate the standards compliance of emails, it extends way beyond email spam verification to prevent serious domain spoofing attacks and preventing phishing attacks. Email security is so important and DMARC has been working towards improving cyber security standards in the email industry for quite some time now. It's important to remember that DMARC isn't a mechanism for you to opt-in to receive emails containing malware or other potentially unwanted material (like links to scams). You should always be careful when downloading software or opening emails from unknown sources. Also, be sure to change your password immediately after receiving any suspicious emails or visiting unfamiliar websites.

How can DMARC Protect against Ransomware?

A ransomware is a piece of malicious code that encrypts all the files on the infected system, effectively locking a person out of his own system. In return for the decrypting key, the hacker asks for large sums of money. Ransomware is a growing problem in the today’s modern world. Businesses have been hit by these attacks and now are facing a difficult decision: pay the ransom or close down their company.

Here’s how ransomware infection becomes a big problem because of not implementing DMARC:

  • When DMARC email authentication is not active, hackers can send fraud emails posing as you to your customers, partners, and internal team members.
  • Fraudulent email messages pass through without getting flagged, effectively delivering ransomware attachments to others. Because the intended victims falsely think the email is from you, they open it, inviting disaster.
  • Ransomware spreads rapidly. If a ransomware is spread within an organization, all connected systems are endangered. Imagine the panic if your personal data was held hostage. Now think of the scale of disruption when an entire organization faces the same issue.
  • On the other hand, if the ransomware was delivered to outsiders, say your partners or end-customers, then your reputation gets tarnished. Sometimes, that may hit your business objectives more than the monetary losses of paying the ransom.

Ransomware has become a major threat to digital organizations, and especially to those who generate or store sensitive data. It's the type of cyber attack that affects your business without any reason given, and it's the most profitable attack vector for attackers because it gets access to your secrets and financial info without you even knowing it. The good news is you can still protect yourself and your business from this attack while making a pay-off to the criminals. This post will show you how with DMARC (Data Security Policy and Awareness), and public-key cryptography (PKI), we can achieve complete and total digital security.

How can implementing DMARC prevent ransomware attacks?

Email remains the number one vector for spreading malware like ransomware, through phishing attempts. Phishing, in turn, relies greatly on domain spoofing, a cyber attack in which the hacker sends emails by ‘borrowing’ your valid domain.

When you implement DMARC, however, you can effectively block all emails that don’t originate from your valid channels. This reduces the risk of such borrowed domains being used to deliver emails. Flagged emails will never reach their intended recipients.

Naturally, a good DMARC service won’t just block flagged emails and leave you to guess for yourself how many and when they were triggered. So, along with implementing DMARC, you also need a reporting tool that will provide with useful insights into your email traffic.

A DMARC Monitoring software is useful because it provides:

  • Frequent and regular monitoring across your email domains.
  • Easy to digest reports which give you actionable steps along with historic and real-time views of data.
  • Proper handling of DMARC data, including DMARC records Generate , SPF records, and   DKIM configurations.

DMARC really acts as the first line of defense in ransomware protection, by protecting your domain from being spoofed, and also alerting you to heightened spoofing activity. Implementing DMARC with Logic is a guided, 3-month process in which we handhold you to achieve the best DMARC configuration to reject all flagged emails, so as to prevent the spread of ransomware and other dangerous email-borne threats.
