This article introduces you to MQTT protocol widely used in IoT.
MQTT is a publish/subscribe (pubsub) wire protocol designed with small devices in mind. Pubsub systems work like a message bus. You send a message to a topic, and any software with a subscription for that topic gets a copy of your message. As a sender you just provide your information to a set of topics and listen for any other topics you might care about.

    Hacking the IoT with MQTT
    In this post i will talk about the MQTT protocol and some security concerns related to it.

    MQTT official note about security (from mqtt.org):

    You can pass a user name and password with an MQTT packet in V3.1 of the protocol. Encryption across the network can be handled with SSL, independently of the MQTT protocol itself (it is worth noting that SSL is not the lightest of protocols, and does add significant network overhead). Additional security can be added by an application encrypting data that it sends and receives, but this is not something built-in to the protocol, in order to keep it simple and lightweight.

    Clients can authenticate to the MQTT Broker sending a user name and password with the CONNECT packet.
