Robert M. Lee, chief executive officer of the industrial cybersecurity firm Dragos Inc., said companies and cyber professionals need to be on guard against an attack. “I would advise analysts to place a particular focus on looking for the tactics, techniques, and procedures of groups that have been shown to operate in the interests of the Iranian state,” Lee said. “For companies that have yet to make proper investments into the cybersecurity of their business, there is not much that can be done quickly in situations like this.”
