Business email compromise is the leading cyber threat for Australian businesses.

Thirty-four per cent of all attacks on businesses come through the inbox.

Email security software validating files shared through Microsoft Teams

Protect More Than Just Email

Your inbox isn’t your only vulnerability.

File-sharing services like SharePoint and Microsoft Teams are attack vectors too.

If one of your staff accounts is compromised, an adversary could use those channels to send malicious files that help them gain access to your network.

Our email security software can be deployed across all common file-sharing and chat programs – ideal for keeping all your comms clean and phishing-free.

Email Security FAQs

What’s a DKIM and a DMARC?

DomainKeys Identified Mail (DKIM) is a type of email authentication. It lets email servers check whether an email that says it came from your domain actually came from your domain. DKIM has 2 parts:

  • a DKIM record, which is stored in your domain’s DNS records (known as a public key)
  • a DKIM header, which is attached to emails sent from your domain (known as a private key).

When a server receives an email from your domain, it checks the DKIM header in your email against the DKIM record. If the DKIM header is verified, the server will consider the email authentic and let it through.

For example, an adversary might try to send a phishing email from ‘hi@itleaders.com.au’. They could set their ‘From:’ field to hi@itleaders.com.au and simply send out the email. If our domain didn’t have a DKIM record, email servers couldn’t confirm whether the email actually came from us or not – the adversary would successfully impersonate us.

Domain-based Message Authentication Reporting and Conformance (DMARC) is a protocol for handling emails that fail to pass DKIM and other checks. Your IT team can set your DMARC policy to mark failed emails as spam, for example, or quarantine them in a separate folder.

Do I need multi-factor authentication for our emails?

Yes, you should have multi-factor authentication (MFA) for all email logins. It’s required to meet all cyber security standards. Without MFA, any kind of password compromise means that an adversary can easily access your email and, from there, infiltrate your network.

What’s spoofing?

‘Spoofing’ occurs when an adversary impersonates someone else over email. For example, someone could pretend to be a supplier you work with, a colleague, or even software support. In a spoofing attack, the impersonated account isn’t actually compromised – the email just appears to be from that person (normally by using a very similar email address or fake sender name).

One of the more recent spoofing methods targeting Microsoft 365 users is the Direct Send exploit. Adversaries use 365’s Direct Send feature, which lets internal emails pass between 365 apps without verification, to mimic emails from real people in your organisation. In many cases, the spoofed emails actually seem to come from the recipient themselves (normally, with a malicious file or link attached that the recipient then clicks out of curiosity).

Like many successful cyber attacks, spoofing is relatively simple – and that’s exactly why it works. The best way to keep your people safe is to invest in good email security and ongoing cyber awareness training.

How can I stop business email compromise attacks?

You can’t stop email phishing and other types of BEC attacks. If you run a business, you’ll almost certainly be targeted by scammers – in some cases, multiple times each day. You can, though, implement countermeasures that keep you and your people safe.

Here’s a brief overview of defences you should have in place.

  1. Have your IT partner install and configure an anti-phishing program like Check Point or SentinelOne.
  2. Set up an approved supplier list and a purchase order system.
  3. Create an SOP for confirming new or changed bank accounts for suppliers and parties you hold funds for (such as law firm clients).
  4. Have your IT partner deliver ongoing cyber awareness training and BEC testing to your staff.

What are the signs of business email compromise?

If you receive an email with one of the following signs, it could be a phishing email.

  • The email contains an invoice from an unknown supplier.
  • The email is from a real supplier, but contains an invoice for work/products you haven’t requested.
  • The email contains an invoice from a real supplier, but with bank details that are different to past invoices.
  • The email is from someone you know, but includes unusual attachments or links.
  • The email contains any of the following red flags:
    • It comes from an authority figure like an executive or HR (such as a request to review an attached document, make an unexpected payment, or fill out a survey).
    • It’s designed to invoke urgency (such as a high-priority request sent late Friday or a reminder to jump on a video call that starts in 5 minutes).
    • It offers freebies or discounts (such as free gift cards from management or half-price coffee at the on-site cafeteria).
    • It deliberately induces fear (such as a threat of legal action for non-payment of an invoice).
  • The email is unexpected (like a software notification you shouldn’t receive or a marketing newsletter you didn’t sign up for).

You can read more about the different phishing styles (and how to prevent them) in ‘Six Signs of Business Email Compromise to Watch For’.
