Simply run those from the litefuzz root and it should save you a lot of time and help enable some of what's needed for automated deployments.

Event Viewer -> Windows Logs -> Applicationto see crashes. optionsThere are a ton of different options and features to take advantage of various target scenarios. The following is a brief explanation and some examples to help understand how to use them. crash directory-olets you specify a crash directory other than the default, which is the crashes/ in the local path. One can use this to manage crash folders for several concurrent fuzzing runs for different apps at the same time. insulate mode-uinsulates the target application from the normal fuzzing process, eg. execs or sending packets over and over and checking for crashes. Instead, this mode was made for interactive client applications, eg. Postman where you can script inside the application to repeat connections for client fuzzing. The target is ran inside of a debugger, the fuzzer is paused to get the user time to click a few buttons or sets the target's config to make it run automatically, user resumes and now you are fuzzing interactive network clients. litefuzz -lk -c "/snap/postman/140/usr/share/Postman/_Postman" -i input/http_responses -a tcp://localhost:8080 -u -n 100000 -zInsulate mode + refresh can be used for interactive clients, eg. run FileZilla in a debugger, but keep hitting F5 to make it reconnect to the server for each new iteration. Also, fuzzing local CLI/GUI servers are only started and ran once inside a debugger to make the process a little more efficient. --keyalso allows you to send keys while fuzzing interactive targets, such as fuzzing FileZilla's parsing of FTP server responses by sending "refre[...]___________________________

How does UDP Flood on webservers work?
I am very likely to have misunderstood something here, since I don't know much about web in general. But shouldn't a UDP flood only work if the victim ports, which receive the UDP traffic aren't blocking all udp data. Doesn't that mean UDP flood only works, when there's a port/service on that webservers, which allows UDP data like a videochat or sth. In conclusion: when there's a webserver that doesn't use UDP at all, isn't it immune to UDP flood attacks?
Probably a lot wrong here, so please go soft on me >~

Wifi-Framework : For Creating Proof-Of-Concepts, Automated Experiments, Test Suites, Fuzzers, And More…
Wifi-Framework is a framework to more easily perform Wi-Fi experiments. It can be used to create fuzzers, implement new attacks, create proof-of-concepts to test for vulnerabilities, automate experiments, implement test suites, and so on.
The main advantage of the framework is that it allows you to reuse Wi-Fi functionality of Linux to more easily implement attacks and/or tests. For instance, the framework can connect to (protected) Wi-Fi networks for you and can broadcast beacons for you when testing clients. In general, any Wi-Fi functionality of Linux can be reused to more quickly implement attacks/tests. The framework accomplishes this by executing test cases on top of the hostap user space daemon.
https://blogger.googleusercontent.com/img/a/AVvXsEi27NzKEWwoQn_Wm7MQ2kEms5PkICD7q5ajoQtftXY4WudUUBqbIvkToXH9TUSLTEJDVa2ZNemv6bZYm6_OEzqw45lCfIZ3Bpt1qpyQDzzAvzRL-j0O9RSJlJTUuaUFuran8f5TQptPNUI5E2lyM_x3MV4dJTP73PYKkeRopUeYVQmMkPsJCPI-uLpF=s1000
If you are new to performing Wi-Fi experiments on Linux it is highly recommended to first read the libwifi Linux Tutorial. When you are implementing basic Wi-Fi attacks without the need to reuse Linux functionality, then the framework provides limited advantages and you can instead consider directly implementing attacks in Scapy and optionally use the libwifi library. Usage
To use the framework:
* Install it by running
* Read the usage tutorial. Example
Say you want to test whether a client ever encrypts frames using an all-zero key. This can happen during a key reinstallation attack. By using the framework you do not need to reimplement all functionality of an access point, but only need to write the following test case:
class ExampleKrackZerokey(Test):
name = “example-krack-zero-key”
kind = Test.Authenticator
def init(self):
super().init([
# Replay 4-Way Handshake Message 3/4.
Action( trigger=Trigger.Connected, action=Action.Function ),
# Receive all frames and search for one encrypted with an all-zero key.
Action( trigger=Trigger.NoTrigger, action=Action.Receive ),
# When we receive such a frame, we can terminate the test.
Action( trigger=Trigger.Received, action=Action.Terminate )
])
def resend(self, station):
# Resend 4-Way Handshake Message 3/4.
station.wpaspy_command(“RESEND_M3 ” + station.clientmac )
def receive(self, station, frame):
if frame[Dot11].addr2 != station.clientmac or not frame.haslayer(Dot11CCMP):
return False
# Check if CCMP-encrypted frame can be decrypted using an all-zero key
plaintext = decrypt_ccmp(frame.getlayer(Dot11), tk=b”\x00″*16)
if plaintext is None: return False
# We received a valid plaintext frame!
log(STATUS,’Client encrypted a frame with an all-zero key!’, color=”green”)
return True
The above test case will create an access point that clients can connect to. After the client connects, a new 3rd message in the 4-way handshake will be sent to the client. A vulnerable client will then start using an all-zero encryption key, which the test case automatically detects.
You can run the above test case using simulated Wi-Fi radios as follows:
./setup/setup-hwsim.sh 4
source setup/venv/bin/activate
./run.py wlan1 example-krack-zero-key
You can connect to the created access point to test it (network
./hostap.py wlan2
By changing the network configuration this AP can easily be configured to use WPA2 or WPA3 and/or can be configured to use enterprise authentication, without making any changes to the test case that we wrote! Additional benefits of using the framework in this example are:
* No need to manually broadcast beacons
* The authentication and association stage [...]
