Relevance of CTF to real hacking

CTF is recommend here.

https://www.reddit.com/r/hacking/comments/a3oicn/how_to_start_hacking_the_ultimate_two_path_guide/

But it is not clear how relevant it is to real hacking. For example, it mentions reverse engineering below. How important it is to participate in rev CTF? It seems to be most of the CTF are made up. Do they really reflect the vulnerabilities binaries in real applications have?

https://youtu.be/8ev9ZX9J45A?t=105

​

It also mentions, pwn, crypto, web, misc in the video. It seems the only thing relevant is web.

​

Could anybody explain why the CTF matters for real applications? Thanks.

SMTP enumeration - where am I going wrong?

I'm learning about some recon elements of a hacking strategy, with OSINT as my objective. I understand the principal of SMTP enumeration to identify email addresses that exist on a domain.

I'm figuring out how to use smtp-user-enum - the form that is pre-installed in Kali. I've troubleshot mostly everything and got the tool to work, but the results are weird. I'm running it against a mail server that I have permission to do so, and on which I know some of the existing email addresses. I created a short users.txt file containing some of the known users and some that definitely are not users.

When I run
smtp-user-enum -M VRFY -U user.txt -t <ip
Ir sets off scanning and then returns a line for every user in my wordlist:
<ip: <userexists


This is regardless of whether or not there is such a user exists. I get the same is I use
-u <single
and also if I use
-D <target
It just keeps telling me that everything I am checking for exists.

Am I missing something obvious?

Invoke-SocksProxy - Socks Proxy, And Reverse Socks Server Using Powershell
http://www.kitploit.com/2021/03/invoke-socksproxy-socks-proxy-and.html

Creates a local or "reverse" Socks (https://www.kitploit.com/search/label/Socks) proxy using powershell. The local proxy is a simple Socks 4/5 proxy. The reverse (https://www.kitploit.com/search/label/Reverse) proxy creates a tcp tunnel by initiating outbond SSL connections that can go through the system's proxy. The tunnel can then be used as a socks proxy on the remote (https://www.kitploit.com/search/label/Remote) host to pivot into the local host's network.
Examples

Local
Create a Socks 4/5 proxy on port 1080: Import-Module .\Invoke-SocksProxy.psm1
Invoke-SocksProxy -bindPort 1080
Increase the maximum number of threads from 200 to 400 Import-Module .\Invoke-SocksProxy.psm1
Invoke-SocksProxy -threads 400

Reverse
Create a "reverse" Socks 4/5 proxy on port 1080 of a remote host: # On the remote host:
# Generate a private key and self signed cert
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout private.key -out cert.pem

# Get the certificate fingerprint (https://www.kitploit.com/search/label/Fingerprint) to verify it:
openssl x509 -in cert.pem -noout -sha1 -fingerprint | cut -d "=" -f 2 | tr -d ":"

# Start the handler
python ReverseSocksProxyHandler.py 443 1080 ./cert.pem ./private.key

# On the local host:
Import-Module .\Invoke-SocksProxy.psm1
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130

# Go through the system proxy:
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -useSystemProxy

# Validate certificate
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -certFingerprint '93061FDB30D69A435ACF96430744C5CC5473D44E'

# Give up after a number of fail ed connections to the handler:
Invoke-ReverseSocksProxy -remotePort 443 -remoteHost 192.168.49.130 -maxRetries 10

Limitations
This is only a subset of the Socks 4 and 5 protocols: It does not support authentication, It does not support UDP or bind (https://www.kitploit.com/search/label/BIND) requests. When the Socks Proxy runs out of available threads, new connections cannot be established until a thread is freed. New features will be implemented in the future. PR are welcome.

How to farm views on sermon audio

I want to screw with my pastor and make it look like our live stream has 100+ viewers. I have no idea how to do it, though I’d imagine you can make a server run multiple views at a time. Does anyone know how to do this?
