![]() We’re releasing nightMARE because it is required for this ICEDID analysis, but stay tuned - more to come as we continue to develop and mature this framework. git clone Īll tools in this tutorial use the nightMARE module, this library implements different algorithms we need for unpacking the various payloads embedded within ICEDID. ![]() In order to use the tools, clone the Elastic Security Lab release repository and install the nightMARE module. Read ICEDID configuration file contained in the fake GZip Gzip_variant/extract_payload_from_core.pyĮxtract and decrypt payloads from the rebuilt ICEDID core binary Malware can be designed to evade detection and infect other systems, so it's important to take all necessary precautions and use specialized tools to protect yourself and your systems.ĥ4d064799115f302a66220b3d0920c1158608a5ba76277666c4ac532b53e855f Environment setupįor this tutorial, we’re using Windows 10 and Python 3.10.Įlastic Security Labs is releasing a set of tools to automate the unpacking process and help analysts and the community respond to ICEDID.Įxtract payloads from ICEDID fake GZip file In this tutorial, we will introduce these tools by unpacking a recent ICEDID sample starting with downloading a copy of the fake GZip binary:Īnalyzing malware can be dangerous to systems and should only be attempted by experienced professionals in a controlled environment, like an isolated virtual machine or analysis sandbox. Following our latest ICEDID research that covers the GZip variant execution chain. ICEDID is known to pack its payloads using custom file formats and a custom encryption scheme. Regular industry reporting, including research publications like this one, help mitigate this threat. ![]() ![]() ICEDID has been linked to the distribution of several distinct malware families including DarkVNC and COBALT STRIKE. ICEDID has always been a prevalent family but achieved even more growth since EMOTET’s temporary disruption in early 2021. ICEDID is a malware family discoveredin 2017 by IBM X-force researchers and is associated with the theft of login credentials, banking information, and other personal information. ![]()
