Session Title | The Great Hotel Hack: Adventures in attacking hospitality industry

"Ever wondered your presence exposed to an unknown entity even when you are promised for full security and discretion in a hotel? Well, it would be scary to know that the hospitality industry is a prime board nowadays for cyber threats as hotels offer many opportunities for hackers and other cybercriminals to target them and therefore resulting in data breaches. Not just important credit card details are a prime reason, but also an overload of guest data, including emails, passport details, home addresses and more. Marriot International where 500 million guests' private information was compromised sets for one of the best examples. Besides data compromise, surgical strikes have been conducted by threat actors against targeted guests at luxury hotels in Asia and the United States. The advanced persistent threat campaign called Darkhotel infected wifi-networks at luxury hotels, prompted the victim to download the malware and thus, succeeded in specifically targeting traveling business executives in a variety of industries and all its prevalence seems to have no end yet.

For a broader look, this time a popular internet gateway device for visitor based networks commonly installed in hotels, malls and other places that provides guests temporary access to Wi-Fi was examined. To see, how the guests and the hotels both have a serious stake in this, we will discourse about the working of guest Wi-Fi systems, different use cases and their attack surfaces: device exploitation, network traffic hi-jacking, accessing guest's details and more. Common attacks and their corresponding defenses will be discussed. This talk will contain demos of attacks to reveal how the remote exploitation of such a device puts millions of guests at risk.
