Unpacking ICEDID

This report is a hands-on technical tutorial from Elastic Security Labs that analyzes an ICEDID 'fake GZip' variant: it demonstrates extracting and decrypting the embedded configuration and custom PE core, rebuilding and loading the core, and unpacking embedded payloads (browser hook binaries). The write-up includes the sample hash, discovered C2 domains, usage of released tooling (nightMARE and multiple Python scripts), and recommendations and warnings for safe analysis in isolated environments.
