It has been more than a year since I last shared Preempt Inspector statistics. Last time we shared Preempt Inspector statistics we found some alarming numbers. With the end of 2018 approaching, I would like to share with you key findings from Preempt Inspector [a free security tool available to download here] to help you focus on the most important security issues you might be facing.
In July, media reported that SingHealth, Singapore’s largest health organization, was breached with 1.5 million medical records stolen. The stolen records included those of Singapore’s prime minister Lee Hsien Loong. Consequently, a special inquiry had taken place, revealing that SingHealth had several security gaps and vulnerabilities which could have easily been exploited by attackers, including a local administrator account with a very weak password (P@ssw0rd). In fact, one of the ways which enabled the attackers to move laterally in the network was by using compromised Citrix local accounts.

We recently reviewed a customer’s network and found that 85%(!) of all users in the network had some unnecessary administrative privilege. The excessive privilege stemmed from an indirect inclusion in a protected admin group. Most Active Directory audit systems easily alert on excessive privileges, but will often miss users who have elevated domain privileges directly through domain discretionary access control list (DACL) configuration. We refer to these users as stealthy admins.
This past March we announced Preempt Inspector, a free app for password strength assessment. The App provided administrators with a better understanding of their AD configuration, especially difficult to estimate parameters, such as duplicate and weak passwords. We analyzed the anonymous data we received from the app, and found some worrying trends, like that 1 in 5 enterprise passwords can be easily compromised.
