About
A raccoon is a tool made for reconnaissance and information gathering with an emphasis on simplicity.
It will do everything from fetching DNS records, retrieving WHOIS information, obtaining TLS data, detecting WAF presence and up to threaded dir busting and subdomain enumeration. Every scan outputs to a corresponding file.
As most of Raccoon's scans are independent and do not rely on each other's results, it utilizes Python's asyncio to run most scans asynchronously.
Raccoon supports Tor/proxy for anonymous routing. It uses default wordlists (for URL fuzzing and subdomain discovery) from the amazing SecLists repository but different lists can be passed as arguments.
For more options - see "Usage".

Installation
For the latest stable version:

pip install raccoon-scanner

Or clone the GitHub repository for the latest features and changes:

git clone https://github.com/evyatarmeged/Raccoon.git
cd Raccoon
python raccoon_src/main.py

Prerequisites
Raccoon uses Nmap to scan ports as well as utilizes some other Nmap scripts and features. It is mandatory that you have it installed before running Raccoon.
OpenSSL is also used for TLS/SSL scans and should be installed as well.

We found out that many TLS implementations are still vulnerable to different variations of a 19-year old Bleichenbacher's attack. Since Hanno argued to have an attack name, we called it ROBOT: https://robotattack.org

Given the new attack variants, we released a new version of TLS-Attacker 2.2, which covers our vulnerabilities.

Bleichenbacher's attack from 1998

In 1998, Daniel Bleichenbacher discovered that the error messages given by SSL servers for errors in the PKCS #1 1.5 padding allow an adversary to execute an adaptive-chosen ciphertext attack. This attack also belongs to the category of padding oracle attacks. By performing the attack, the adversary exploits different responses returned by the server that decrypts the requests and validates the PKCS#1 1.5 padding. Given such a server, the attacker can use it as an oracle and decrypt ciphertexts.

We refer to one of our previous blog posts for more details.

OK, so what is new in our research?

In our research we performed scans of several well-known hosts and found out many of them are vulnerable to different forms of the attack. In the original paper, an oracle was constructed from a server that responded with different TLS alert messages. In 2014, further side-channels like timings were exploited. However, all the previous studies have considered mostly open source implementations. Only a few vulnerabilities have been found.

In our scans we could identify more than seven vulnerable products and open source software implementations, including F5, Radware, Cisco, Erlang, Bouncy Castle, or WolfSSL. We identified new side-channels triggered by incomplete protocol flows or TCP socket states.

For example, some F5 products would respond to a malformed ciphertext located in the ClientKeyExchange message with a TLS alert 40 (handshake failure) but allow connections to timeout if the decryption was successful. We could observe this behaviour only when sending incomplete TLS handshakes missing ChangeCipherSpec and Finished messages.

See our paper for more interesting results.

Release of TLS-Attacker 2.2

These new findings motivated us to implement the complete detection of Bleichenbacher attacks in our TLS-Attacker. Before our research, TLS-Attacker had implemented a basic Bleichenbacher attack evaluation with full TLS protocol flows. We extended this evaluation with shortened protocol flows with missing ChangeCipherSpec and Finished messages, and implemented an oracle detection based on TCP timeouts and duplicated TLS alerts. In addition, Robert (@ic0ns) added many fixes and merged features like replay attacks on 0-RTT in TLS 1.3.

You can find the newest version release here: https://github.com/RUB-NDS/TLS-Attacker/releases/tag/v2.2

TLS-Attacker allows you to automatically send differently formatted PKCS#1 encrypted messages and observe the server behavior:

$ java -jar Attacks.jar bleichenbacher -connect [host]:[port]

In case the server responds with different error messages, it is most likely vulnerable. The following example provides an example of a vulnerable server detection output:

14:12:42 [main] CONSOLE attacks.impl.Attacker - A server is considered vulnerable to this attack if it responds differently to the test vectors.
14:12:42 [main] CONSOLE attacks.impl.Attacker - A server is considered secure if it always responds the same way.
14:12:49 [main] CONSOLE attacks.impl.Attacker - Found a difference in responses in the Complete TLS protocol flow with CCS and Finished messages.
14:12:49 [main] CONSOLE attacks.impl.Attacker - The server seems to respond with different record contents.
14:12:49 [main] INFO  attacks.Main - Vulnerable:true

In this case TLS-Attacker identified that sending different PKCS#1 messages results in different server responses (the record contents are different).

Network Mapping (NMAP)

Basically NMAP stands for Network Mapping. A free open source tool used for scanning ports, service detection, operating system detection and IP address detection of the targeted machine. Moreover, it performs a quick and efficient scanning a large number of machines in a single session to gathered information about ports and system connected to the network. It can be used over UNIX, LINUX and Windows.

There are some terminologies which we should understand directly whenever we heard like Open ports, Filtered ports and Unfiltered ports.

Open Ports means the target machine accepts incoming request on that port cause these ports are used to accept packets due to the configuration of TCP and UDP.

Filtered ports means the ports are usually opened but due to firewall or network filtering the nmap doesn't detect the open ports.

Unfiltered means the nmap is unable to determine whether the port is open or filtered while the port is accessible.

Types Of NMAP Scan

Scan Type	Description
Null Scan	This scan is performed by both an ethical hackers and black hat hackers. This scan is used to identify the TCP port whether it is open or closed. Moreover, it only works over UNIX based systems.
TCP connect	The attacker makes a full TCP connection to the target system. There's an opportunity to connect the specifically port which you want to connect with. SYN/ACK signal observed for open ports while RST/ACK signal observed for closed ports.
ACK scan	Discovering the state of firewall with the help ACK scan whether it is stateful or stateless. This scan is typically used for the detection of filtered ports if ports are filtered. Moreover, it only works over the UNIX based systems.
Windows scan	This type of scan is similar to the ACK scan but there is ability to detect an open ports as well filtered ports.
SYN stealth scan	This malicious attack is mostly performed by attacker to detect the communication ports without making full connection to the network. This is also known as half-open scanning.

All NMAP Commands

-sT	TCP connect scan
-sS	SYN scan

-oX	XML output
-oG	Greppable output
-oA	All output
-T Paranoid	Serial scan; 300 sec between scans
-T Sneaky	Serial scan; 15 sec between scans
-T Polite	Serial scan; .4 sec between scans
-T Normal	Parallel scan
-T Aggressive	Parallel scan, 300 sec timeout, and 1.25 sec/probe
-T Insane	Parallel scan, 75 sec timeout, and .3 sec/probe

How to Scan

You can perform nmap scanning over the windows command prompt followed by the syntax below. For example, If you wanna scan the host with the IP address 192.168.2.1 using a TCP connect scan type, enter this command:

nmap 192.168.2.1 –sT

nmap -sT 192.168.2.1
