The Big Target on Cyber Insurers‘ Backs

Here at IntSights, a Rapid7 company, our goal is to equip organizations around the world with an understanding of the threats facing them in today’s cyber threat landscape. Most recently, we took a focused look at the insurance industry — a highly targeted vertical due to the amount of personally identifiable information (PII) these organizations hold. We’ve collected our findings in the “2022 Insurance Industry Cyber Threat Landscape Report,“ which you can read in full right now.

While conducting this research, one key takeaway caught my eye: the big target on cyber insurers‘ backs. Some of these organizations provide cyber insurance coverage for businesses, so in the event of a breach that imposes significant costs on a targeted business, that business is not 100% financially liable.

According to our cyber threat intelligence research, cyber insurance providers are even more appealing targets for bad actors in an industry already full of appealing targets. That begged the question: Why are cyber insurers so highly targeted? And what can they do to protect themselves in the face of these threats?

Cyber insurance providers are data goldmines

Typically, bad actors are angling to breach insurance companies to access PII or to collect policyholder details that they can use for insurance fraud. However, when hackers target cyber insurers, they’re seeking even more specific types of data, such as cyber insurance policy details and information outlining the security standards cyber insurance clients follow.

Why is this the case? A ransomware operation could, for example, leverage this information to build a list of potential targets covered under a cyber insurance policy. Some cyber insurance providers will pay an insured victim’s ransom, and if this is stated in the policy, these clients will bump up on the list of high-value targets, because the bad actors may assume they’re more likely to pay a ransom.

Knowledge of the security standards cyber insurers require their customers to fulfill is also dangerous in the wrong hands. It can help attackers craft their techniques to evade victims‘ security measures. For example, they may completely avoid strongly defended points of entry and instead target areas of the perimeter with weaker protections. While not a guaranteed path to success, it gives bad actors more information to work with, and that’s never a good thing.

These are very real — and unique — threats facing the cyber insurance segment, and we’ve seen a few breaches like this play out already. In 2021, CNA Financial

, a leading US insurance company that provides cyber insurance policies, suffered a cyberattack and reportedly

paid a ransom of $40 million USD to ransomware operators.

Other cyber insurance companies that experienced breaches include Tokio Marine Insurance Singapore

in August 2021 and global cyber insurer AXA in May 2021. The AXA breach

happened shortly after it announced it would stop reimbursing new French customers for ransom payments after ransomware attacks. This was in response to claims by French officials that cyber insurance coverage of ransom payments encouraged more ransomware attacks and higher ransom demands. The attackers may have aimed to punish AXA for this decision, just going to show that the French officials may have been correct in their claim.

How cyber insurers can better protect their data

To defend themselves and their clients against ransomware attacks and data breaches, cyber insurers can follow a few simple steps:

  • Avoid publicly identifying specific customers by name for any reason. For example, it’s common practice to list the names of your biggest brands or enterprise clients on your website. However, this may make your business more appealing to hackers. They may view your organization as a gateway to gain access to your clients — if they can break through your security perimeter, they may get an even larger payload of data from the clients that can foot more expensive ransoms.
  • Refrain from listing any details about the cyber insurance policies you provide. If you publish information about how much your policy compensates the insured in the event of a ransomware attack or security breach, bad actors can use this data to calculate an optimal ransom amount that’s high enough to maximize profit but low enough for victims to accept. As such, your policy details will need extra protection, including encryption and network segmentation.
  • Scrutinize public-facing web applications and other infrastructure, like automated quote tools. Misconfiguration
  • of these applications and bugs can inadvertently expose customer data. Hackers will often target these types of online portals and tools to learn more about a cyber insurer’s policies, and in some cases, they can even gain access to the information they store, which can then be exploited.
  • Finally, employ rigorous cyber threat intelligence. A key component of any risk management and cybersecurity strategy, threat intelligence can help cyber insurance providers understand the types of data that bad actors hope to steal from them, the methods they may use to obtain it, and even the ransomware operators targeting them. These insights can help your team shore up security against impending threats and remediate malicious actions faster in the event of a breach.

By following these recommendations, cyber insurance providers around the world can better protect their data as well as the sensitive information of their partners, clients, and customers. Because of all the valuable data these organizations house, the target on their backs won’t go away, so the best defensive strategy is a proactive one. Comprehensive cyber threat intelligence can play a critical role there.
