YARA and Script Library

Hello,we have many times request from customer to prolong backup images from 6 months to 1 year.I know, some complicated things like restore VM and provide backup again with 1 year or export this image, map to backup job and setup copy job with one year.Does exist any command in PowerShell to change expiration date?thank you

Hello Community!Your input is needed. Almost two years ago, I created a PowerShell script that checks if one of the scanned files matches a SHA256 value by comparing the values to a list of known hash values. It only searched in specific directories.What would be better than using file-level restore? Right, Data Integration API!Since version 12.3.1, Veeam offers the possibility of working with the Data Integration API via the REST API. To improve the whole thing, I have created a Python script that scans the mounted backup file system for suspicious files by comparing their hash values against known threats stored in a local database. The database uses data from Malware Bazaar and the LOLBAS project (“Living Off The Land Binaries and Scripts”), a catalog with legitima

Hi All,Wasnt sure where to post this so adding it here.Had a requirement recently to automate the process of adding YARA rules and found that ransomware.live has a great list! fantastic resources for those that havent looked at it yet.leveraging their API, I basically pull the rules and then copy them to the VBR server, pretty simple but hopefully going to improve it as things move on but figured id share with the wider team.https://homelabpro.xyz/posts/2025-05-09-dynamically-download-yara-rules/

Backups store important data, and if they are not protected, anyone who gets access can read them. Encrypting backups ensures that if someone gains access to backup files, they remain unreadable without the proper encryption key.Checking if backup jobs are configured to encrypt the backup data can sometimes be difficult, especially if there are many backup jobs. To simplify this process, I created a PowerShell script that helps to check the backup job encryption configuration settings quickly. The script retrieves information for the following Veeam backup job types:VMware Backup Agent Backup File Backup Object Storage BackupPowerShell sample output for Jobtype “File Backup”The output displays details such as the repository name and path, the encryption status (Encry

Hello everyone. Last time we explored how to identify basic file Indicators of Compromise (IoCs), develop YARA rules to detect malicious actors, and incorporate these rules into Veeam Backup & Replication to identify potential malware in our backups.Taking it a step further, today we will explore how to automatically generate YARA rules using YarGen. YarGenYarGen is a tool that generates YARA rules from a specified malware file. It identifies unique strings within the malware and excludes those prevalent in non-malicious files. This is achieved using YarGen's comprehensive database of strings and opcodes typically found in non-malicious files. Essentially, it creates YARA rules from strings in malware files while discarding those also present in goodware files

Hello together,before you update VEEAM to Version 12 using VMware vCenter/ESXi please check VMs HardDisks for duplicate UUID. In Version 11 this was never a problem. In the new Version VEEAM checks the UUID and backup will fail.VMware has no problem with that most time. But they know the Problem - https://kb.vmware.com/s/article/2006865This command will find any HardDisk with duplicate UUID - please note that this is VMware PowerCLI commandGet-VM | Get-HardDisk | Select @{N='VM';E={$_.Parent.Name}}, @{N='Uuid';E={$_.ExtensionData.Backing.Uuid}} | Group-Object -Property Uuid | ?{ $_.Count -gt 1 }As Service Provider such changes in VEEAM are a total disaster!!

Veeam Backup & Replication 12.3 – A big release with many new functions. Let me show you some of the exciting new possibilities with REST API. And yes, I have also created some scripts 😉Scanning Backups & Veeam Threat HunterVeeam Backup & Replication offers various methods of scanning backups for malware. The Secure Restore feature allows for malware scanning during recovery, preventing the reintroduction of infected files. The Scan Backup functionality will enable you to check backups for malware on-demand.

Starting with Veeam Backup & Replication 12.3, it is possible to exclude specific events from being sent to the Syslog server. This can be done manually per event, or you can import an XML file with the events to be filtered.Handling this task and finding the necessary information can be time-consuming. Executing this task manually is “boring” and error-prone, so I created a simple PowerShell script to make the process easier by generating an XML file based on your chosen filters. Whether filtering by event IDs, categories, or specific filter types like Info, Warning, or Error, this script makes this task more fun.🕺🏿💃🏽For more details and examples of usage, check out the

Hello Community!It's been two years since I published a script for a OneDrive for Business file check in this community. And even back then I had the code ready that also checks recovered files for possible malware. Of course, Microsoft 365 also has certain mechanisms, which are documented here.Trust is good, control is betterI have now taken up my idea again and packed it into a new script. The script restores files from the lastest OneDrive for Business restore point and scans them for threats using Windows

Hi everyone, I'm using Veeam for quite a while now but recently we added some NetApp ONTAP devices to the storage infrastructure. And for each also a NAS Filer object under unstructured data. I can select a NAS Filer and create a file backup job easily. But I want to automate this if possible.I can use Get-NetAppHost to get the ONTAP device and then use Get-VBRUnstructuredServer combined with Get-VBRNASServerPath but I can't link it all together… Also, when I look at an already configured job I cannot reverse engineer this to usable PS code.Can someone point me in the right direction to create a file backup job of a share on a NAS filer with PowerShell?

Inherency:Since we bill by actual disk usage for our client utilizing CloudConnect, the existing reports are non-functional for reporting and billing (They report pre-deduplication/reflink data).  It took a while to figure out, but there is a way to calculate actual disk space used on a per directory on an immutable repository.Solution:Using: https://community.veeam.com/blogs-and-podcasts-57/check-reflink-and-spared-space-on-xfs-repositories-244 I have extrapolated a script that will give the disk usage of each folder (IE: client) on an immutable repo.  This isn't "Data used"; that is what Veeam reports.  This is "Disk Used".  The actual size on disk after reflinks (duplicated data is only counted once). A note about this script; it appears that the original blog entr

Hello, As you may know I have been working for some time with several tools to document or diagram the Veeam Backup & Replica Infrastructure. In the latest version of Veeam.Diagrammer the ability to generate a diagram of the infrastructure has been added. Here is the link:https://techmyth.blog/posts/veeam-diagraming-infra/ Greetings from the Caribbean :)

Since this is modifying the firewall, you might lock yourself out remotely if you are executing the steps incorrectly or you have a slightly different setupIf you are running RHEL or any experimental derivative (in my case Rocky 8.8), you can use firewalld to configure the firewall. Firewalld uses zones in which you can allow ports or services based on the incoming interface or IP sources. By default, all the traffic is “allowed” based on the rules in the public zone (or better the interfaces are by default assigned to the public zone). You can test this with# What is the default zonefirewall-cmd --get-default-zone# What are the active zones, by default only the public zonefirewall-cmd --get-active-zones# List all the rules in the publi

Hello everyone, First of all, I would like to ask my community because I am not fully familiar with Yara rules. When scanning for Malware Detection with Yara rules, can you see which files have Malware in which locations with Yara Rules? When I do a direct Malware scan, if there is malware, it shows the machine under the malware tab but does not give details. What can I do for more details here Hello everyone,

This is me being a bit lazy, so apologize in advance. Does anyone have a script, or know of a VBR type report which retrieves change rate for VMs in a Backup Job? Obviously I know about VONE, but we don’t use that (maybe I can do a temp 30-day trial install...but would like something a bit quicker and temporary). I’ve run into a situation since last wk where 1 or a few VMs in a job have changed the backup rate significantly since last wk, by almost 10-fold, causing me to run out of space not only on this Job Repo, but my storage array! I’m trying to work through it, but would like to know the culprit(s) to let the app owners know to chill! haha There was a couple app VMs with updates, etc since last wk, so I have an idea a little bit of what’s going on. But, I’d like to pinpoint things a bit better.Thank you Community!

With the release of the version 8 of VB 365, some additional permissions are needed on the registred app. Nothing to think about when you’re deploying a new app, but when you’re upgrading, you coudl re-use the existing app and extend it with the new requirements. I’m not a programmer, but I’ve tried to setup a small powershell script that based on your Application ID adds the necessary rights and also adds the app to the Global Reader role.Feel free to check and modify it !

Could anyone help for the following scenario . [Veeam.Backup.Core.CBackupSession]::GetAll() For the above command do we have any commands as the above one not fetching all backup session ids done for particular location.

We have a Veeam AWS Appliance in its own backup account on the latest version, 7.1.08We are backing up more than 200 AWS accounts. I am looking for a Terraform code that, when included in creating a new AWS Account, automatically imports the account to the Veeam appliance. I looked into the Veeam Hub and did not find any. The only Terraform code I found was for deploying the Veeam AWS Appliance.Does anyone have the Terraform code, or is this possible with Veeam AWS Appliance?Thanks,Zahra   

Hello,These last few weeks I have had the time to give some attention to the AsBuiltReport.Veeam.VB365 report. This time a lot of improvements and new sessions were added to collect much more information about the Veeam Backup for Microsoft 365 infrastructure. Here I provide you with the changes:https://github.com/AsBuiltReport/AsBuiltReport.Veeam.VB365/releases/tag/v0.3.0 Now the reason for writing this post is to share with all of you about a project I have been working on in my spare time and it is about Diagramming the Veeam infrastructure. In this new version of the AsBuiltReport.Veeam.VB365 report I added the ability to create a simple diagram of the deployed VB365 components. This tool uses Graphviz a

Hi Community,after Rick's announcement (thanks for the initiative), I couldn't resist creating another script for the community.As documented, you can add one YARA rule file to the scan process. But what if you want to use multiple YARA rules? Of course you could work with a so-called index file, which refers to the individual YARA rules, but this brings a problem with it, because the YARA rules are stored on the VBR server, but the scan process provides the backups on the mount server and only one YARA rule can be used (This is a topic for another blog post - stay tuned).  What if we would like to use all YARA rules from Rick's Top 10 Ransomw
