joana&pedro: Scanning TLS Server Configurations With Burp Suite

In this post, we present our new Burp Suite extension "TLS-Attacker".
Using this extension penetration testers and security researchers can assess the security of TLS server configurations directly from within Burp Suite.
The extension is based on the TLS-Attacker framework and the TLS-Scanner, both of which are developed by the Chair for Network and Data Security.

You can find the latest release of our extension at: https://github.com/RUB-NDS/TLS-Attacker-BurpExtension/releases

TLS-Scanner

Thanks to the seamless integration of the TLS-Scanner into the BurpSuite, the penetration tester only needs to configure a single parameter: the host to be scanned. After clicking the Scan button, the extension runs the default checks and responds with a report that allows penetration testers to quickly determine potential issues in the server's TLS configuration. Basic tests check the supported cipher suites and protocol versions. In addition, several known attacks on TLS are automatically evaluated, including Bleichenbacher's attack, Padding Oracles, and Invalid Curve attacks.

Furthermore, the extension allows fine-tuning for the configuration of the underlying TLS-Scanner. The two parameters parallelProbes and overallThreads can be used to improve the scan performance (at the cost of increased network load and resource usage).

It is also possible to configure the granularity of the scan using Scan Detail and Danger Level. The level of detail contained in the returned scan report can also be controlled using the Report Detail setting.

Please refer to the GitHub repositories linked above for further details on configuration and usage of TLS-Scanner.

Scan History

If several hosts are scanned, the Scan History tab keeps track of the preformed scans and is a useful tool when comparing the results of subsequent scans.

Additional functions will follow in later versions

Currently, we are working on integrating an at-a-glance rating mechanism to allow for easily estimating the security of a scanned host's TLS configuration.

This is a combined work of Nurullah Erinola, Nils Engelbertz, David Herring, Juraj Somorovsky, Vladislav Mladenov, and Robert Merget. The research was supported by the European Commission through the FutureTrust project (grant 700542-Future-Trust-H2020-DS-2015-1).

If you would like to learn more about TLS, Juraj and Robert will give a TLS Training at Ruhrsec on the 27th of May 2019. There are still a few seats left.

Quando eu te falei em amor

Quando os meus olhos te tocaram
Eu senti que encontrara
A outra, metade de mim
Tive medo de acordar
Como se vivesse um sonho
Que não pensei em realizar
E a força do desejo
Faz me chegar perto de ti

Quando eu te falei em amor
Tu sorriste para mim
E o mundo ficou bem melhor
Quando eu te falei em amor
Nos sentimos os dois
Que o amanha vem depois
E não no fim

Estas linhas que hoje escrevo
São do livro da memória
Do que eu sinto por ti
E tudo o que tu me das
É parte da história que eu ainda não vivi
E a força do desejo
Faz me chegar de ti

Quando eu te falei em amor
Tu sorriste para mim
E o mundo ficou bem melhor
Quando eu te falei em amor
Nos sentimos os dois
Que o amanha vem depois e não no fim

Collide

The dawn is breaking
A light shining through
You're barely waking
And I'm tangled up in you
Yeah

But I'm open, you're closed
Where I follow, you'll go
I worry I won't see your face
Light up again

Even the best fall down sometimes
Even the wrong words seem to rhyme
Out of the doubt that fills my mind
I somehow find, you and I collide

I'm quiet, you know
You make a first impression
I've found I'm scared to know
I'm always on your mind

Even the best fall down sometimes
Even the stars refuse to shine
Out of the back you fall in time
I somehow find, you and I collide

Don't stop here
I've lost my place
I'm close behind

Even the best fall down sometimes
Even the wrong words seem to rhyme
Out of the doubt that fills your mind

You finally find, you and I collide
You finally find You and I collide
You finally findYou and I collide

Everything

You're a falling star, You're the get away
car.
You're the line in the sand when I go too
far.
You're the swimming pool, on an August day.
And You're the perfect thing to see.

And you play it coy, but it's kinda cute.
Ah, When you smile at me you know exactly what you
do.
Baby don't pretend, that you don't know it's
true.
Cause you can see it when I look at you.

And in this crazy life, and through these crazy
times
It's you, it's you, You make me sing.
You're every line, you're every word, you're
everything.

You're a carousel, you're a wishing well,
And you light me up, when you ring my bell.
You're a mystery, you're from outer space,
You're every minute of my everyday.

And I can't believe, uh that I'm your man,
And I get to kiss you baby just because I
can.
Whatever comes our way, ah we'll see it
through,
And you know that's what our love can do.

And in this crazy life, and through these crazy
times
It's you, it's you, You make me sing
You're every line, you're every word, you're
everything.

So, La, La, La, La, La, La, La
So, La, La, La, La, La, La, La

And in this crazy life, and through these crazy
times
It's you, it's you, You make me sing.
You're every line, you're every word, you're
everything.
You're every song, and I sing along.
Cause you're my everything.
yeah, yeah

So, La, La, La, La, La, La, La
So, La, La, La, La, La, La, La
