In today’s blog post, we will be going over how to create honey folders with no additional tooling.
Cyber Deception allows for the placement of traps with no business value, “normal” is defined as no interaction.
Its value lies in being probed, attacked, or compromised.
Any interaction is abnormal and thus actionable.
We will be leveraging a Desktop.ini file, which provides us with the ability to load icons from a remote location.
NOTE: To enable this feature, you have to create the value `”EnableShellShortcutIconRemotePath”=dword:00000001`
in the registry key `[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Explorer]`
STEPS:
1. Create the Desktop.ini file with the following content:
NOTE: Adjust the domain name to your use case; the domain does not have to exist.
You can encode information in the domain name such as an ID for the honey folder and client information using environment variables.
2. Give the folder and the Desktop.ini file the system attribute:
You might also want to make the Desktop.ini file hidden. In this case you would use the following command:
After completing these steps, every time someone opens the folder that contains the honey folder, a DNS request will be made.
To have the DNS request logged, you should include the following in your Sysmon configuration under Event ID 22.
After ingesting the Sysmon logs into your SIEM you have a high-fidelity detection mechanism, if implemented correctly, with almost zero false positives.
User vulnerabilities, threat hunting and MDATP
For almost every organization security is important, no matter that we are talking about physical security or digital. This fact won’t be written over neither the type of the organization/company nor the size of it. In the digital world often we make the mistake that we lay back behind the safety of firewall, antivirus and email filers. And not caring about the education of our employees in information security.
Transforming Splunk to a semi-SOAR platform
SOAR (Security Orchestration, Automation and Response) is a solution stack of compatible software programs that allow an organization to collect data about security threats from multiple sources and respond to low-level security events without human assistance. The goal of using a SOAR stack is to improve the efficiency of physical and digital security operations.
