HashtagMarkus / msfvenom-reverse-tcp-WaitForSingleObject.md
Created November 30, 2020 00:10 — forked from mgeeky/msfvenom-reverse-tcp-WaitForSingleObject.md
(OSCE/CTP, Module #3: Backdooring PE Files) Document explaining how to locate WaitForSingleObject(..., INFINITE) within msfvenom's (4.12.23-dev) generated payload and how to fix the payload's glitches.

Looking for WaitForSingleObject call within modern msfvenom generated payload.

Abstract

This is a document explaining how to locate WaitForSingleObject(..., INFINITE) within msfvenom's (4.12.23-dev) generated payload and how to fix the payload's glitches. It goes through the analysis of a windows/shell_reverse_tcp payload, touching issues like stack alignment, WaitForSingleObject locating & patching. It has been written when I realised there are many topics on the Offensive-Security OSCE/CTP forums touching problem of finding this particular Windows API. Since RE is one of my stronger FU's I decided to write down my explanation of the subject.

Example creation of the first Titan graph
graph = TitanFactory.open('conf/titan-cassandra-solr.properties')
GraphOfTheGodsFactory.load(graph)
g = graph.traversal()
// find hercules
hercules = g.V().has('name', 'hercules').next()
// find parents name of hercules
g.V(hercules).out('father', 'mother').values('name')
// find all places within the given circle
g.E().has('place', geoWithin(Geoshape.circle(37.97, 23.72, 50)))
