Into The Weeds: How We Run Detonate

To automate this process and test our protections at scale, we built Detonate, a system that is used by security research engineers to measure the efficacy of our Elastic Security solution in an automated fashion.

What is Detonate?

What does it help us with?

Measuring Efficacy

Supporting existing protections

Threat research

Evaluating new protections

Click, Click… Boom! Automating Protections Testing with Detonate

ICEDID is known to pack its payloads using custom file formats and a custom encryption scheme. We are releasing a set of tools to automate the unpacking process and help analysts and the community respond to ICEDID.

Environment setup

Unpacking the fake GZip

Decrypting the core binary and configuration files

Reading the configuration

Rebuilding the core binary for static analysis

Executing the core binary (Windows only)

Unpacking and rebuilding payloads from the rebuilt core binary
