Echo Up

Drop a File
From Just the Shell.

No outbound, no SMB, no curl. Echo Up turns the file on your laptop into a single command you paste into the shell you already have. The remote machine reconstructs it from nothing but what you typed.

Neuron Echo Up
The Problem

Your Kit Is on the
Wrong Side of the Connection.

You have a shell on a target box. No outbound, no SMB, no curl. You need to drop a file on disk and the network will not help.

The work that mattered is already done. You picked the path, stayed quiet, got the shell.

Now your kit is on the wrong side of the connection. The recon scripts, the beacon, the obfuscated payload, all sitting on your laptop while the box that needs them sits behind a firewall that will not let it reach back.

Open a side channel and you light up every detection your client paid for.

The Solution

Echo Up. Built Into Neuron.

Echo Up turns any file into a paste-ready command for the shell context you are already in. Base64 under the hood, so binaries work the same as scripts. No callback, no staging server, no new traffic for the SOC to flag.

Bash, CMD, and PowerShell Base64 Modes

Pick the shell you are in. The output is tuned to its quoting rules and its base64 decoder. Binaries reconstruct the same as scripts.

No Callback, No Staging Server

The file moves through the shell you already have. Nothing new goes on the wire. No second-stage download for the SOC to flag.

Shell Escaping Handled For You

Quotes, newlines, backslashes, and dollar signs are escaped to match the target shell. The command you paste is the command that runs.

Quoted-Echo Variants for Stripped-Down Boxes

When base64 is not on the target, fall back to single-quoted, double-quoted, or no-quote echo chains. Multi-line for readability, single-line when you need one paste.

Load a Local File. Destination Auto-Fills.

Drag in the recon script, the beacon, the payload. The destination filename pre-populates. Switch the encoding mode and the command regenerates in place.

One-Click Copy Into Your Shell

Hit Copy. Switch to your shell. Paste. The remote machine reconstructs the file from nothing but what you typed.

How It Works

Load. Pick. Paste.

Three steps from the file on your laptop to the file on the target.

1

Load the File Into Echo Up

Choose a file from your machine or paste contents directly. The destination filename fills in automatically.

2

Pick Bash, CMD, or PowerShell

Match the shell you are in. Quoted-echo fallbacks are there for targets without a base64 decoder.

3

Paste Into Your Shell

Copy the generated command, paste it into the shell you already have, and the file lands on the remote box.
