Unpacking ICEDID

Elastic Security Labs released analysis tools and open source utilities to unpack ICEDID, a malware family that steals credentials and banking information using custom file formats and encryption. The research covers the GZip variant execution chain, including extraction of encrypted payloads, decryption, core binary reconstruction, and analysis of embedded modules such as browser hooking capabilities. Practitioners can now use the released nightMARE library and Python scripts to automate malware unpacking and enable faster incident response.

Why it matters: Security analysts and incident response teams handling ICEDID samples can now rapidly extract, decrypt, and analyze payloads without manual reverse engineering, reducing time to identify command and control (C2) domains, configuration data, and secondary malware like DarkVNC or Cobalt Strike.
