Smart Buildings Under Siege: Are You Ready for the Siegeware Showdown?
I have to admit, even though it has been around since 2019, this is a new one for me. However, based on the description of #Siegeware, I came to the conclusion that I had seen one firsthand. I have even published articles and done presentations on this incident that required 92 days to recover from ransomware/equipment destruction. After reading the definition, I realized it was a Siegeware attack.
What is Siegeware?
Siegeware is a type of ransomware that specifically targets smart buildings and their control systems. In a siegeware attack, cybercriminals gain control over a building's critical systems, such as heating, ventilation, air conditioning (HVAC), lighting, security, and fire alarms. They then demand a ransom to restore control to the building's owners or operators.
The term "siegeware" reflects the idea of holding a building "under siege" by taking over its automated systems and disrupting its normal operations until the ransom is paid. The first notable discussions about siegeware appeared around 2019.
What Systems are Targeted?
Siegeware attacks on building control systems can take various forms, depending on the specific vulnerabilities and systems targeted. Some common types are:
Ransom Demands and Threats
Control Over Systems
Attackers often demonstrate control over building systems to intimidate victims before issuing ransom demands.
Issuing Ransom Demands
Ransom demands typically follow the demonstration of control, pressuring victims to comply to avoid disruption.
Escalation of Threats
If the ransom is not paid, threats may escalate, risking further disruption or making buildings uninhabitable.
Potential Legal Repercussions
Legal Consequences of Attacks
Building owners may face lawsuits and high fines due to siegeware attacks, impacting their financial stability.
Reputational Damage
Attacks can lead to reputational damage, affecting customer trust and long-term business relationships.
Safety Hazards
If siegeware attacks create safety hazards for occupants, building owners may face severe legal liabilities.

1 个月Fred, unfortunately and unless action is taken, siegeware will be a continuing trend, particularly to hold at risk and for ransom facilities that support reindustrialization of America, data centers, hospitals, transportation hubs, food storage, and supply chain exchange points.
