Regshot is a very useful tool which takes a snapshot of registry and then takes a second snapshot after the malware is run and then it will compare the two registry snapshots and shows the difference. You can use compare strings to compare the strings for the process on disk vs in memory to confirm if there has been any process replacement in memory.ĭependency walker can be used in process explorer, this is useful when you find a process and want to know which dll’s it calls However, it’s useless if an attacker uses process replacement. Which is useful if you suspect that a process has been hijacked by malware. You can use the Verify option to verify if a process is legit in terms of the signature from the manufacturer of the software to see if the signatures match. Its used to list active processes, DLLs loaded by a process, various process properties, and overall system information. Process Explorer is an extremely powerful task manager for performing dynamic analysis.
You can also filter on individual system calls such as WriteFile or other suspicious calls. You can set procmon to filter on one executable running on the system. Procmon monitors all system calls it can gather as soon as it is run because procmon uses RAM to log events until is is told to stop capturing, it can crash a virtual machine using all available memory, to avoid this run procmon for limited periods. This tool can miss device driver activity.
It combines the legacy tools: FileMon and RegMon Process monitor (procmon) is an advanced monitoring tool for Windows that provides a way to monitor registry, file systems, network, process, and thread activity.
To run a dll file you can convert it to a portal executable using runddl32.exe Procmon Here are those notes on Chapter 3 Basic Dynamic Analysis.ĭynamic analysis actually runs the malware on a live system (generally disconnected from the internet) exe files not working on Windows 7 so instead I decided to do some notes on the chapter instead. Sadly, I was unable to do the exercises due to the. Practical Malware Analysis Chapter 3 Notes
