Hack a BT Low Energy (BLE) butt plug

Butt plug – Hush by Lovesense

Few weeks ago I bought a Bluetooth Low Energy (BLE) butt plug to test the (in)security of BLE protocol.

This caught my attention after researchers told us that a lot of sex toys use this protocol to allow remote control that is insecure by design.

The great Simone evilsocket Margaritelli wrote a BLE scanner called BLEAH (get it on github) and a wonderful post on how to use it to hack BLE devices. I strongly suggest you to read the post before moving on. Continue reading “Hack a BT Low Energy (BLE) butt plug”

MineMeld: threat intelligence automation – search received IoC events with Splunk [4]

This post is the fourth of a series on Threat Intelligence Automation topic.
Post 1: Architecture and Hardening of MineMeld
Post 2: Foundation: write a custom prototype and SOC integration
Post 3: Export internal IoC to the community

After having laid the foundations for building a community with the previous posts, it’s now time to make some advanced analysis of the received IoC.
In post 2 I integrated MineMeld output nodes into Splunk SOC near-real-time engine to automate SOC IoC access detection. This configuration strengthens the analysis and response capabilities of our SOC.

With this post I show you how to integrate MineMeld miners IoC events (update and withdraw of remote IoC) into Splunk engine so you can use Splunk search advanced features to have a deeper look into the IoC received from the miners.
This is also an important information for a SOC because if you have an IoC hit the first think to do is to understand where the IoC come from, if it was sent by more than one source etc

MineMeld: threat intelligence automation – export internal IoC to the community [3]

This post is the third of a series on Threat Intelligence Automation topic.
Post 1: Architecture and Hardening of MineMeld
Post 2: Foundation: write a custom prototype and SOC integration
Post 4: Search received IoC events with Splunk

After building the architecture and integrating the InfoSec feeds from italian CERT-PA into MineMeld and the near-real-time SOC engine, it’s time to put another brick to build an effective community: export internal IoC to the community in a standard format so authorized parties can get it and use them as they want.

The ultimate goal is to build a community that can share IoC using a standard language and a transport mechanism (STIX/TAXXI) getting data from heterogeneous sources (more integration examples in next posts) and injecting data into the community network.

So let’s start with the configuration steps. Continue reading “MineMeld: threat intelligence automation – export internal IoC to the community [3]”

MineMeld: threat intelligence automation – foundation: write a custom prototype and SOC integration (Splunk) [2]

Minemeld Integration
Minemeld Integration

On the first post of my threat intelligence automation jurney I wrote why I choosed MineMeld, the architecture implemented and the hardening steps. One of the goals is to connect MineMeld to heterogeneous external sources to get IoC (Indicators of Compromise) and integrate it into our i-SOC (Information Security Operation Center) near-real-time engine to get evidences of security events to be analyzed by i-SOC analysts.

In this post I show the foundation of the threat intelligence automation model: how I wrote a custom prototype to get the InfoSec feeds from italian CERT-PA (Public Administration – italian web site) and how I integrated these feeds into Splunk near-real-time engine.
I started with this integration because InfoSec has very good feeds (IP, URLs, domains) that are not just copy&paste from OSINT sources but are often updated and automatically analyzed to check that IoC are still “alive”.

This page and this page give you all the information needed to understand how MineMeld works, so RTFM before moving on 😉 Continue reading “MineMeld: threat intelligence automation – foundation: write a custom prototype and SOC integration (Splunk) [2]”

Last slide at my HackInBo talk (italian) was about how to automatically integrate threat intelligence feeds into our near-real-time Information Security Operation Center (i-SOC) SPLUNK engine to reduce the time spent by SOC security analysts on IoC (Indicators of Compromise) analysis.

Threat Intelligence question from #HiB17

At the time I was testing an open source project from PaloAlto: MineMeld. It was the right choice; after extensive tests MineMeld now help me to solve the challenges I had in the past while playing with IoC coming from various threat intelligence sources: collection automation, unduplication, aging and SOC integration.

MineMeld can also share our internal IoC to the italian infosec community we are now building from the ground. We are working hard on this and I’m really confident we will succeed (want to join? DM me on twitter or in the comments). Continue reading “MineMeld: threat intelligence automation – architecture and hardening [1]”

The WannaCry journey from a SOC point of view – internal sinkholing of killswitch servers

[ see also: The WannaCry journey from a SOC point of view ]

In the previous post I described how our Security Operation Center managed the WannaCry news.

We also made a lot of side activities in the past hours and one of these was to implement an internal sinkholing of the killswitch servers in case some clients where infected; with a working local sinkholing we where able to avoid the ransomware spreading in case of infection.

How? Let me explain.
