## VirusTotal and Whitelisting setup
|
|
|
|
Setting up VirusTotal hash submissions and whitelisting:
|
|
|
|
The hash checker requires Post-VirusTotal:
|
|
|
|
- https://github.com/darkoperator/Posh-VirusTotal
|
|
|
|
It also requires a VirusTotal API key:
|
|
|
|
- https://www.virustotal.com/en/documentation/public-api/
|
|
|
|
Then configure your VirusTotal API key:
|
|
```powershell
|
|
set-VTAPIKey -APIKey <API Key>
|
|
```
|
|
The script assumes a personal API key, and waits 15 seconds between submissions.
|
|
|
|
## Generating a Whitelist
|
|
|
|
Install hashdeep: https://github.com/jessek/hashdeep/releases
|
|
|
|
Generate your own whitelist on Windows:
|
|
|
|
```
|
|
hashdeep.exe -r / -c md5,sha1,sha56 > raw-hashes.csv
|
|
```
|
|
Note that hashdeep, etc., has a dumb recursive design (from the manpage):
|
|
|
|
> Enables recursive mode. All subdirectories are traversed. Please note that recursive mode cannot be used to examine all files of a given file extension. For example, calling hashdeep -r *.txt will examine all files in directories that end in .txt. Move file to Unix/Linux, remove Windows carriage returns, grab EXEs and DLLs, make CSV.
|
|
|
|
On Linux/Unix: take the raw CSV, remove the carriage returns, select DLLs, EXEs and SYS files, grab the 2nd field to the end, and create a new whitelist:
|
|
```
|
|
cat raw-hashes.csv | tr -d '\r' | egrep "\.dll$|\.exe$|\.sys$" | cut -d, -f2- > file-whitelist.csv
|
|
```
|
|
|
|
Add this entry to the first line of the file (only sha256 and path are currently needed)
|
|
```
|
|
md5,sha1,sha256,path
|
|
```
|
