HOW TO DOMINATE A COUNTRY.

WHAT ARE YOU ?We are:• Security Researchers• Security enthusiasts• Students, corporate sheep (read: auditors),

programmers, pentesters• Beer lovers We are not:• Lulzsec• Anonymous• Hacking group• And no we wont help you hack you girlfriends facebook!

• Ok… that depends on the amount of beer involved!

WHO ARE YOU ?

• Tiago Henriques• Team founder and leader @ PTCoreSec• Pentester/Researcher @ 7Elements• @Balgan

• Tiago Martins• Team vice-founder @ PTCoreSec• Researcher • @Gank_101

• Filipe Reis• Programmer @ PTCoreSec• Intern @ Layer8• @fjdreis

WHO ARE YOU ?

TOPICS

WE ARE NOT

RESPONSIBLE FOR ANY ILLEGAL ACTS OR ACTIONS PRACTICED BY YOU OR ANYONE THAT LEARNS SOMETHING FROM TODAY’S PRESENTATION.

CAUSING CHAOS.

Q:If you guys were an attacker that was out to cause real damage or get profit, how would you go on about it ?A:This is what we would do, control as many machines in that country, penetrate critical systems and get as much intel/info as possible.

CAUSING CHAOS.

And that’s what we are gonna talk about today!

HOW IT ALL GOT STARTED

We’re hackers! We love knowing how to break things and how others would go on about breaking things!

The difference between us and others is simple:

• We want to break things legally and find a way to fix things.• We want to learn about new things and help people.

PORT SCANNING….

HOW IT ALL GOT STARTED

We saw some talks that really inspired us given by two great people

HD Moore Fyodor

HOWEVER…We also ran into a bit of a problem…

Portscanning might or might not be illegal in Portugal!

No one is actually sure, and we talked with multiple people:• Police• Sysadmins• Researchers• Security professionals

WHAT TO DO ?• So, if you can’t port scan, how do u find out what ur enemies attack

surface is ?

• How do u know out if the entire infrastructure u rely on everyday is vulnerable or safe?

• Security by obscurity? Right that works well….

But like I said before…we’re hackers, so we hacked the law and rules and bent them to our favor!

WHAT TO DO ?

• Port scanning isn’t illegal in 2 nice places! Sweden and USA!

• So we got 2 friends of ours who knew nothing of portscanning and wanted to learn, taught them how to portscan the big internets, and then they sent the raw results to us…

PORT SCANNING

• Tools of the trade:• Nmap• Wkhtmltoimage• Python• Scapy• Linux• NodeJS• MongoDB• C• Redbull + Lots of nights awake +

Frustration

PORT SCANNING - PROCESS

1. Get Portugal’s CIDRs

2. Decide on a set of services you consider important

3. Check which ip’s have those port’s open

4. Check versions running of those services

Actual scanning.


1. Get Portugal’s CIDRsThere are two places where you can get these:

• http://software77.net/geo-ip/

• ftp://ftp.ripe.net/pub/stats/ripencc/delegated-ripencc-latest2.80.0.0/145.43.0.0/185.44.192.0/205.158.0.0/185.159.216.0/215.172.144.0/2131.22.128.0/1737.28.192.0/1837.189.0.0/1646.50.0.0/1746.182.32.0/2146.189.128.0/1762.28.0.0/1662.48.128.0/18

http://software77.net/geo-ip/

ftp://ftp.ripe.net/pub/stats/ripencc/delegated-ripencc-latest


2. Decide on a set of services you consider importantID Port Number TCP/UDP Service

1 80TCP http2 443TCP https3 8080TCP http alternative4 21TCP FTP5 22TCP SSH6 23TCP Telnet7 53UDP DNS8 445TCP Samba9 139TCP Samba

3. Check which ip’s have those port’s open

4. Check versions running of those services

This is where it get’s tricky!

PORT SCANNING - PROCESS• Portugal on the internet….

5,822,240 allocated ip’s

Dynamic ips

GPRS

PORT SCANNING - PROCESS• So as we mentioned, we devided the actual scanning into two parts!

And you might be wondering why…

Common nmap scan for TCP

nmap -iL ipswithftp -oA port21-FTP-with-Services -sS -sV -p21 -T5 -PN

The problem of this, is that DNS resolution and –sV (Service detection) are very slow.

So how do we solve this problem? We obviously want the domains the ips are associated with, and the versions of the services running.

PORT SCANNING - PROCESS• Do the fast things on the 6 mil ips and then do the slow stuff merely

on the ips that are running the service we want to analyse.• nmap -iL CIDRSPT.txt -oA port21-FTP -sS -p21

-T5 -PN --host-timeout 1501 –min-hostgroup 400 --min-parallelism 10 -n

• Then we will have the list of ips that have FTP running on port 21 on 3 files:

• Port21-FTP.xml• Port21-FTP.gnmap• Port21-FTP.nmap

• Extract ips from gnmap:

cat port21-FTP.gnmap | grep -w "21/open" | awk '{print $2}' > IPSWITHFTP.TXT

PORT SCANNING - PROCESS• Do the show things only the ips that have our service running.

• nmap -iL IPSWITHFTP.txt -oA port21-FTP-FINAL -sV -p21 -T5 -PN --host-timeout 1501 –min-hostgroup 400 --min-parallelism 10

• Then we will have the list of ips that have FTP running on port 21 AND the version of those services on 3 files:

• Port21-FTP-FINAL.xml• Port21-FTP-FINAL.gnmap• Port21-FTP-FINAL.nmap

PORT SCANNING - PROCESS• However…we still have UDP… and let me tell u….


Nmap also has a UDP mode… -sU however it doesn’t work very well without -sV (read: its shit!), when testing it on our lab we noticed that most of the times nmap wasn’t able to detect if there was a service running or not.

The reason for this is: “UDP scanning is slow as open/filtered ports typically don't respond so nmap has to time out and then retransmit whilst closed ports will send a ICMP port unreachable error, which systems typically rate limit.”

When we started, it took us around 4 Weeks to scan UDP on the entire country on 1 port….

PORT SCANNING - PROCESSSolution ?

SCAPY!

Service running on port:11111

Server

Client


Result of that script ?On lab testing….


Result of that script ?On internet testing….


When we started, it took us around +4 Weeks to scan UDP on the entire country on 1 port using NMap…. -We took this as a baseline first run to improve…

Our second run, we used python+scapy and it went down!! 1 week – well not bad for a second run, but 1 week for a port ?

Our third run, we used python+multithreading fu + scapy + blackmamba – 3 days – and this was the best we brought it down to without bringing in the big guns (read: “asking HD Moore for help”)

Forth run – C

Yup entire .pt (1 port ) scanned in 4 minutes and 45 seconds.

PORT SCANNING - END

So we had our kick ass friends, send us our kick ass raw results… now what do we do with them ?

PORT SCANNING - END

Terminals are fun, BUT we want an easier way to look at our data…

So…. We wrote a tool:Presenting for the first time: Nmap Query Center!

PORT SCANNING - END

DEMO TIME!

Mongo DB NodeJS

ExpressSocket.ioNodeJS

Scan Importer

Nmap Minion

Store processed scan data

Process raw nmap data to json so we can better process the information

Show all the pretty data to the client

Nmap scans run here

PORT SCANNING - END

Well that’s it folks…Thank you for coming

PORT SCANNING – END

Just kidding! We did promise a few more things didn’t we ?

PORT SCANNING – THE PROJECT

While we were preparing for codebits…

We received something in the mail….


Raspi


And it got us thinking…

Port scanning, doesn’t require a great CPU, nor a huge amount of ram…


So we decided to create a distributed port scanning project…


We grabbed the

And added a custom set of scripts to it…


PORT SCANNING – HOW DOES IT WORK?

Step 1 – PTCoreSec admins request a job (scan) on the backend.

Step 2 – Server side checks current number of live raspi minions.

Step 3 – Server divides de CIDRS by the different clients and sends them over.

Step 4 – Clients (minions) do the scans and XMLRPC send them back to the server.

Step 5 – Server imports these scans into the MongoDB backend.

I ASK ONLY ONE THING OF U

Leave your whitehats at home, and

SHODAN

SHODAN is a search engine that lets you find specific computers (routers, servers, etc.) using a variety of filters. Some have also described it as a public port scan directory or a search engine of banners.

Another way of putting it would be:

Is the

Of these

Now combine this:

With these:

And you get a lot of these

Also if you do anything ilegal and get caught, you’ll get one of these:

SHODAN

Now its when u ask

SHODAN

Accessing that website will give u a bar, where you can type queries and obtain results.

Your queries, can ask for PORTS, Countries, strings contained in the banners, and all sorts of other things

Following is a sample set of queries that can lead to some interesting results:

If you want to quickly check for stuff (web related) that has no authentication, use NMAP!

A LITTLE TIP…

First, let’s get wkhtmltoimage:

wget http://wkhtmltopdf.googlecode.com/files/wkhtmltoimage-0.11.0_rc1-static-i386.tar.bz2tar -jxvf wkhtmltoimage-0.11.0_rc1-static-i386.tar.bz2cp wkhtmltoimage-i386 /usr/local/bin/

Next, let’s get and install the Nmap module:git clone git://github.com/SpiderLabs/Nmap-Tools.gitcd Nmap-Tools/NSE/cp http-screenshot.nse /usr/local/share/nmap/scripts/nmap --script-updatedb

A LITTLE TIP…

Then, do your shodan search and use:

A LITTLE TIP…

This automatically exports a list of ips u can import into nmap

Then…A LITTLE TIP…

And nmap, will automatically take screen shots of the first pages that appear and store them, then u just need to look at those!

A LITTLE TIP…

To end…

OPEN PORTS!

SCARY SHIT!

DEFACE 1 SCARY?

NO!

SCARY SHIT!

DEFACE 2 SCARY?

Well… disturbing, scary? Not so much!

SCARY SHIT!

SCARY SHIT!

SCARY SHIT!

SHODAN – THE BAD PART

• Imports nmap scans from their servers on a rotational basis, so its not always 100% updated! Confirmed this by correlating some of the shodan results with our personal results!

• For example on mysql servers, Shodan would find 785, where our results showed 3000+

SHODAN – THE GOOD PART

• Good querying system

• If port scanning is illegal in your country, you’re out of trouble if u use shodan, because ur just querying data acquired by them.
