To further our commitment, we’ve adopted a proactive approach to help insurers understand their exposures and craft strategies to mitigate losses.

Guidewire Cyence Takes Action

When a cyber vulnerability is identified by a credible source (such as NIST), the Guidewire Cyence team works to reverse-engineer the identified vulnerability, but for a different reason from the hackers. By understanding the mechanism, our engineers isolate the publicly observable characteristics of a firm’s cyber profile that suggest its susceptibility to such a vulnerability. We leverage a custom assessment tool that collates these characteristics from our data collection engine and identifies the affected firms.

In a recent Cyber Bulletin, we informed our customers of the following vulnerabilities that were recently discovered in commonly used hardware and software. Guidewire Cyence customers could then determine if these vulnerabilities impacted the companies in their portfolios and contact their affected policyholders to inform them of the patches and other safety workarounds.

Zyxel NAS and Firewall Vulnerability

A vulnerability was discovered on Zyxel NAS (Network Attached Storage) and firewall products. This vulnerability could allow attackers to remotely execute code on a vulnerable device.

Zyxel released patches for devices that are in their warranty and support period, but the vulnerability also affects unpatched devices that are no longer under warranty. Guidewire Cyence identified 126 companies in the Guidewire Cyence database that could be impacted for this reason.

Microsoft Exchange Server Vulnerability

A vulnerability was discovered in Microsoft Exchange Server that could allow an attacker to run arbitrary code on the server, thereby fully compromising the server.

The vulnerability exists in Microsoft Exchange Server 2010, 2013, 2016, and 2019. Although Microsoft has released program updates that eliminate the vulnerability, Guidewire Cyence has identified 591 companies in the Guidewire Cyence database that use this software and could be vulnerable.

Apache Tomcat Vulnerability

A vulnerability was discovered in Apache Tomcat that could allow an attacker to perform the following actions:

  • Install and execute programs
  • View, change, and delete files
  • Create new accounts with full user rights

The vulnerability exists in all supported versions of Tomcat. The Apache Software Foundation has released updated versions that eliminate the vulnerability. Guidewire Cyence identified 619 companies in the Guidewire Cyence database that use this software and could be vulnerable.
