EPS. 10 – Cell Phone WiFi
Sophisticated attackers seek to inflict damage on a geography they are unhappy with for some reason. The attackers create a useful, attractive, free cell phone app. The attackers use targeted social media attacks to persuade office workers at critical infrastructure sites in the
offending geography to download the free app. The app runs continuously in the background of the cell phone. While at their critical infrastructure workplaces, the app instructs the phone to periodically scan for Wi-Fi networks and report such networks to a command and control center. The attackers again, use social media, social engineering and phishing attacks to impersonate insiders at their target organizations, and extract passwords for the Wi-Fi networks. Several of these password protected networks are part of critical infrastructure industrial control systems. The attackers log into these networks using the compromised cell phones and carry out reconnaissance by remote control until they find computer components vulnerable to simple denial of service attacks, such as erasing hard drives or SYN floods. The attackers compromise plant operations, triggering an unplanned shutdown. They then disconnect from the Wi-Fi networks, and then repeat this attack periodically
THE TOP 20 CYBERATTACKS ON INDUSTRIAL CONTROL SYSTEMS
These Top 20 attacks have been selected to represent cyber threats to industrial sites across a wide range of circumstances, consequences and sophistication. No industrial operation is free of risk, and different industrial enterprises may legitimately have different “appetites” for certain types of risks. In this series we show how to use the Top 20 Cyberattacks to compare the strength of two security postures at a hypothetical water treatment plant: Defence in depth 2013 (software based security) vs. that same security posture plus a unidirectional security gateway device providing hardware-enfonced security). We ask the question, does either defensive posture reliably defeat each attack? Over the course of 20 episodes we build a score card that can be used to easily communicate risk reduction benefits to business decision-makers who are not familiar with cyber-security.
