How Cyber Insurance Saved This Small Business

The following story is based on a real-life insurance claim experienced by a professional services client with Cyber Insurance arranged by Aon. All names have been anonymised for privacy reasons.

An 8-person professional services firm in New Zealand, focused on providing excellent service to its clients, suddenly found itself facing a business email compromise event targeting their administration/accounts manager. 

The threat actor gained unauthorised access to the business’s mailbox, leading to a significant breach. 

The breach was discovered when approximately 400 clients of the firm received emails with "overdue statements" featuring altered bank information. A vigilant client, using an alternative communication method, contacted the firm to verify the bank change. This alert prompted the firm to recognise the breach, and they immediately notified their cyber insurance provider, who immediately activated incident response support that included:

•    IT support: To triage, contain, and remove the threat actor’s presence from the compromised mailbox.

•    Client notification: To reach out to all 400 clients to inform them of the manipulated statements and to prevent any payments to the threat actor.

•    IT forensics: To conduct a thorough scan of the breached mailbox to identify that sensitive personal information, including ID documents and financial information, had been accessed and some of it exfiltrated.

•    Legal support: To provide advice regarding the privacy breach and assist in notifying the Office of the Privacy Commissioner and the victims of the breach.

•    ID monitoring and protection: To offer services to the victims to monitor for any publication of their information on the web or dark web.


The financial impact

The total cost of the cyber claim amounted to $73,000. This figure, while significant, was mitigated by the timely intervention and support provided by the insurer. Without cyber insurance, the financial impact could have severely affected the firm’s ability to operate effectively.


The true value of cyber insurance

This case highlights the importance of cyber insurance for small businesses. The insurance coverage and vendor support allowed the firm to manage the breach effectively, minimising potential financial losses and reputational damage. The incident underscores the need for robust cyber security measures and the value of having a responsive insurance partner.
