Automating Malware Deobfuscation with Binary Ninja Writing a Static Unpacker This section will teach participants how to automate unpacking and decryption of malware samples. This will be accomplished using the Qakbot sample as an example. The Qakbot sample is packed (obfuscated using an external program that “unpacks itself”) and therefore we will perform multiple hands-on exercises to automate the extraction of Qakbot from its packed form using Binary Ninja, PEFile and Binary Refinery. + The first exercise will teach attendees how to use Binary Ninja to identify the encryption algorithm used by the first stage of the packer and how to extract key information to decrypt the second stage. +The next exercise will teach attendees how to use PEFile to extract an embedded resource from the packed binary. Once extracted, the resource will then be decrypted using the key information from the first exercise The next exercise will teach attendees how to use Binary Refinery to carve binary files from the decrypted resource Code Slides Workshop Manual

SCCMSecrets.py A python utility that builds upon existing SCCM research. It goes beyond NAA credentials extraction, and aims to provide a comprehensive approach regarding SCCM policies exploitation. The tool can be executed from various levels of privileges, and will attempt to uncover potential misconfigurations related to policies distribution. It will dump the content of all secret policies encountered as well as collection variables, in addition to package scripts hosted on the distribution points. Finally, it can be used throughout the intrusion process by configuring it to impersonate legitimate SCCM clients, in order to pivot across device collections. For more details regarding the tool and its usage, see the associated article at: https://www.synacktiv.com/publications/sccmsecretspy-exploiting-sccm-policies-distribution-for-credentials-harvesting-initial P.S. Another tool allowing to dump SCCM distribution point resources via HTTP: https://github.com/badsectorlabs/sccm-http-looter

themida-unmutate A Python 3 tool to statically deobfuscate functions protected by Themida, WinLicense and Code Virtualizer 3.x's mutation-based obfuscation. The tool has been tested on Themida up to version 3.1.9. It's expected to work on WinLicense and Code Virtualizer as well. https://github.com/ergrelet/themida-unmutate A Binary Ninja plugin is also available here. #unpacking #packer
