This is the story of how the security of OT devices in the field can be modernized virtual isolation in the cloud, adding both authentication and encryption into the mix. Bill Moore, founder and CEO of Xona, explains how you can virtualize the OT network and interact with it, adding 2FA and encryption to legacy systems already in the field. 

This is the story of the secret life of cellular chips and why we need to mitigate against the unintended access they provide. Deral Heiland, Principal Security Research for IoT at Rapid 7, describes a research project he presented at the IoT Village at DEF CON 32 where they compiled AT command manuals from various vendors, discovering unexpected functionalities, such as internal web services.

When we think of IoT, we first think of our smart light bulbs, our smart TVs, our smart baby monitors. However, we don't typically associate IoT with high-performance race cars, and yet they collect terabytes of data each race. Austin Allen, Director of Solutions Architecture at Airlock Digital, discusses the growing presence of smart devices and the responsibility of securing them—should it be the developers who write the code, or the individuals who implement it?

What would happen if your GPS signal were jammed? It would impact more than just navigation – you'd also lose access to financial data and power. Joe Marshall, Senior IoT Strategist and Threat Researcher at Cisco Talos, discusses an innovative solution to maintain the country's power grid operations in the event of GPS jamming, whether it's a precautionary measure or an act of war.

Cybercriminal tactics against ICS include direct threats against individuals for MFA credentials, sometimes escalating to physical violence if they won’t share. Jim Coyle, US Public Sector CTO for Lookout, warns about the increasing use of Android in critical Industrial Control Systems (ICS), such as HVAC systems, and how stealing MFA tokens from mobile devices could affect critical services like healthcare, finance, and water supply, depending on the goals of the attackers.

If smart buildings are vulnerable to hacking, what about smart offices? Even devices like printers and lighting systems could give an attacker a way in. John Terrill, CSO at Phosphorus, recalls a moment while working at a hedge fund when he found himself in a room filled with priceless art. He realized that the security cameras safeguarding these artworks were operating on outdated software, potentially containing known vulnerabilities.

If you are in IT, you are probably not thinking about the risks associated with the Otis Elevator or the Coke machine. Maybe you should. Chester Wisnieski, the director and global field CTO at Sophos, points out that IoT devices, big and small, create an outsized threat to any organization. And that’s why IoT vendors need to secure these devices, even if they only “phone home” for more Coke. If they’re on your network, they need to be secured.

Political hacktivism once mainly focused on website defacement. Now it has shifted to targeting physical devices, affecting critical infrastructure such as water treatment plants. At Black Hat USA 2024, Noam Moshe from Claroty highlighted how the HMIs in PLC devices from Israeli manufacturers may be susceptible to political attacks by nation-state actors using unknown vulnerabilities in the PComm protocol.

What if you could build your own embedded security tools, glitching devices for a fraction of the cost that you might expect. Like having a $150,000 laser setup for less than $500. A talk at Black Hat USA 2024 says you can. Sam Beaumont (Panth13r), Director of Transportation, mobility and cyber physical systems at NetSPI, and Larry Trowell (patch), Director of hardware embedded systems at NetSPI, along with a team of others, say that you can. Their talk, Laser Beams & Light Streams: Letting Hackers Go Pew Pew, Building Affordable Light-Based Hardware Security Tooling, should be a wake up call for all IoT and OT device vendors who should defend our IoT and OT devices, even against the unlikely attacks. Because soon enough, those attacks will become likely.

Too few vulnerabilities in industrial control systems (ICS) are assigned CVEs because of client non-disclosure agreements. This results in repeatedly discovering the same vulnerabilities for different clients, especially in critical infrastructure. Don C. Weber from IOActive shares his experiences as an ICS security professional and suggests improvements, including following the SANS best practices for ICS security..
