An attempted cyberattack against the network equipment of the Auly Chlorine Distillation Station which supplies liquid chlorine to water  and wastewater treatment facilities in  23 provinces of Ukraine, as well as Moldova and Belarus. Over the course of several minutes, the company’s technological process control systems and the systems for detecting signs of emergencies were being attacked by the VPNFilter malware. If not foiled, the malware could exfiltrate credentials, monitor equipment, and could render an infected device completely inoperable.
