To install Raccine, run the following command from the command line or from PowerShell:
To upgrade Raccine, run the following command from the command line or from PowerShell:
To uninstall Raccine, run the following command from the command line or from PowerShell:
Deployment Method:
This applies to both open source and commercial editions of Chocolatey.
1. Enter Your Internal Repository Url
(this should look similar to https://community.chocolatey.org/api/v2/)
2. Setup Your Environment
1. Ensure you are set for organizational deployment
Please see the organizational deployment guide
2. Get the package into your environment
Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)-
Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the package and push it to a repository Download
-
Open Source
-
Download the package:
Download - Follow manual internalization instructions
-
-
Package Internalizer (C4B)
-
Run: (additional options)
choco download raccine --internalize --source=https://community.chocolatey.org/api/v2/
-
For package and dependencies run:
choco push --source="'INTERNAL REPO URL'"
- Automate package internalization
-
Run: (additional options)
3. Copy Your Script
choco upgrade raccine -y --source="'INTERNAL REPO URL'" [other options]
See options you can pass to upgrade.
See best practices for scripting.
Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.
If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:
choco upgrade raccine -y --source="'INTERNAL REPO URL'"
$exitCode = $LASTEXITCODE
Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
Exit 0
}
Exit $exitCode

Raccine
A Simple Ransomware Protection
Why
We see ransomware delete all shadow copies using vssadmin
pretty often. What if we could just intercept that request and kill the invoking process? Let's try to create a simple vaccine.
How it works
We register a debugger for vssadmin.exe
(and wmic.exe
), which is our compiled raccine.exe
. Raccine is a binary, that first collects all PIDs of the parent processes and then tries to kill all parent processes.
Avantages:
- The method is rather generic
- We don't have to replace a system file (
vssadmin.exe
orwmic.exe
), which could lead to integrity problems and could break our raccination on each patch day - Flexible YARA rule scanning of command line params for malicious activity
- The changes are easy to undo
- Runs on Windows 7 / Windows 2008 R2 or higher
- No running executable or additional service required (agent-less)
Disadvantages / Blind Spots:
- The legitimate use of
vssadmin.exe delete shadows
(or any other blacklisted combination) isn't possible anymore - It even kills the processes that tried to invoke
vssadmin.exe delete shadows
, which could be a backup process - This won't catch methods in which the malicious process isn't one of the processes in the tree that has invoked
vssadmin.exe
(e.g. viaschtasks
)
Example
Emotet without Raccine - Link
Emotet with Raccine - Link (ignore the process activity that is related to the Raccine installation)
The infection gets nipped in the bud.
Warning !!!
USE IT AT YOUR OWN RISK!
You won't be able to run commands that use the blacklisted commands on a raccinated machine anymore until your apply the uninstall patch raccine-reg-patch-uninstall.reg
. This could break various backup solutions that run that specific command during their work. It will not only block that request but kills all processes in that tree including the backup solution and its invoking process.
If you have a solid security monitoring that logs all process executions, you could check your logs to see if vssadmin.exe delete shadows
, vssadmin.exe resize shadowstorage ...
or the other blocked command lines are frequently or sporadically used for legitimate purposes in which case you should refrain from using Raccine.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
Chocolatey Pro provides runtime protection from possible malware.
