ERNW Hardening Repository

Today we started publishing several of our hardening documents to a dedicated GitHub repository — and we’re quite excited about it! It took a while to develop a suitable markdown template to support all the requirements you have when you write a hardening guide, but we’re online now!

At the moment, only a few hardening guides are online, but that should continuously increase in the future.

Click here for the GitHub ERNW Hardening Repository!

Cheers,

Matthias

Some Notes on Utilizing Telco Networks for Penetration Tests

After a couple of years in pentesting Telco Networks, I’d like to give you some insight into our pentesting methodology and setup we are using for testing “Mobile and Telecommunication Devices”. I am not talking about pentesting professional providers’ equipment (as in previous blogposts), it is about pentesting of devices that have a modem in place like a lot of IoT devices (you know about the fridge having a GSM Modem, right?) do.

Introduction of a new hardware guy

Hi folks!

We couldn’t be more proud to welcome such a predestined #1 hardware hacking victim, than VICTor is!
Before Brian and I gave a lecture on hardware hacking last week at DHBW Mosbach, we felt, that we needed a custom victim which is fully documented and provides a good “hackability” to the students.
Surely we could also have used some cheap $wifi_ap, but here’s the thing: Would you really want to use a device which you don’t really know? Mostly, there’s a massive lack of documentation regarding the SoCs used…not to mention the unavailability of schematics and layouts.
As we wanted to teach students the basics of hardware hacking effectively, we decided to create something by ourselves.

Introducing VICTor...

Review about the System and Security Info iOS App from SektionEins GmbH

Dear readers of Insinuator,

Today I want to give a little review about the latest app released by SektionEins called “System and Security Info” due to its recent media appearance. So first of all the app can be obtained via the Apple App store for 0,99€ at the time this article was written. This article will try to answer two basic questions: for whom (or “which groups of people”) is this app helpful, and which security features does this app actually has. The design of the app is straight forward and pretty minimalistic with a clean and modern design. The first page of the Application called “Overview” provides nothing more than the current CPU usage of the device, with detailed subdivision in User, Idle, Total and Load. The next section provides an overview about the used RAM divided into Wire, Active RAM usage, Inactive RAM usage, “other”, free and the total amount of the device’s ram. The next option shows the used and unused part of the devices available storage, with “used”, “free” and total amount of space. While these features can be handled with several other (free and open source) applications I won’t write a comment wether it  these components make sense.

Check your SAP landscape for default Solution Manager users

This is a guest post from Joris van de Vis @jvis,  on his upcoming Troopers talk. Additional credits go to: Robin Vleeschhouwer, and Fred van de Langenberg.


 

Picture1

As presented at Troopers this year, ERP-SEC research has uncovered a set of potential default accounts related to the use of SAP Solution Manager. These default accounts might pose a big risk to your SAP supported business as some of them have wide authorisations. It is therefore important to check if they exist in your landscape and change the default passwords.

Cloud Security & Trust

Hi,

I gave a presentation on Cloud Security, Compliance & Trust the other day. The basic message was to look beyond the Cloud buzzword and see the actual technologies which are used, understand which security principles still apply and which need to be re-thought, giving a rough direction about regulatory compliance in Cloud environments (which of course is non-binding, as I’m not a lawyer), and the importance of trust evaluations (especially) when it comes to Cloud services.
