How would a port scan get through nat? Is it happening in JS?

When can #Firefox get this feature? I had no idea #portscanning from the web was a thing. That's far too invasive. Is there a sane way to set this up locally #Linux with #iptables?

RHC CyberPills: oggi scopriamo cos'è il port-scanning.

Il port scanning è una tecnica utilizzata dagli #amministratori di #rete e dagli #hacker (sia etici che criminali) per scoprire quali porte di un #sistema #informatico sono aperte e quali #servizi o #applicazioni si stanno utilizzando.

In pratica, il #portscanning consiste nell'invio di #pacchetti di dati verso le porte del #sistema, al fine di verificare se esse sono aperte o chiuse.

Questa tecnica può essere utilizzata per #identificare potenziali punti deboli della #sicurezza della rete, ma anche per scopi #malevoli, come individuare porte aperte su un sistema per sfruttarle e infiltrarsi nel sistema stesso.

Nmap, or Network Mapper, is a powerful tool for network discovery and security auditing. It works by sending a series of packets to target hosts and analyzing the responses to determine the host's operating system, open ports, and other information.

[ #AdventOfCyber2022 #tryhackme] Day 4

In Day 4 Tasks, we learn on how to do #scanning

Scanning is procedure to identify living hosts, ports, and services running on specify target.

There are 2 types of scan based on their intrusiveness:
1. #passivescan
Passive scan is scanning without touching/interacting directly with the target device. The scan usually done being capturing packages using #wireshark. However, the information you can get are fairly limited.

2. #activescanning
Active scan is scanning that interacting directly with the target service, usually by sending pocket to specific asset. The scanning will immediately do a deep scan to get a lot of information from the target.

Several #scanning techniques:
1. #networkscanning
The scan that aimed to map the entire network of the target. When an attacker has mapped the entire network of their target, they can launch #exploit through the weakness of enemy network.

2. #portscanning
The scan that aimed to look for any open port that capable of sending and retrieving request/data.

3. #vulnerabilityscanning
The scan that aimed to identify what kind of #vulnerability existed on the network that may threaten the system.

Tools to do scanning:
1. #nmap
NMAP is one of the most popular tool used for scanning a network. It can be used to scan open ports, open #networkprotocols , open #services, running #operatingsystem, etc.

2. #nikto
Nikto is a open source that can be used to identify #website for #vulnerability. It allows to search a #website for their subdomains, outdated servers, #debug messages, and many more.
