of use. As a result, infected users could not actually send the required payment confirmation to the perpetrator. Additionally, if the computer's filesystem was FAT based, the MFT encryption sequence was skipped, and only the ransomware's message was displayed, allowing data to be recovered trivially. Microsoft had already released patches for supported versions of Windows in March 2017 to address the EternalBlue vulnerability. This was followed by patches for unsupported versions of Windows (such as Windows XP) in May 2017, in the direct wake of WannaCry. Wired believed that "based on the extent of damage Petya has caused so far, though, it appears that many companies have put off patching, despite the clear and potentially devastating threat of a similar ransomware spread." Some enterprises may consider it too disruptive to install updates on certain systems, either due to possible downtime or compatibility concerns, which can be problematic in some environments. Impact In a report published by Wired, a White House assessment pegged the total damages brought about by NotPetya to more than $10 billion. This was confirmed by former Homeland Security advisor Tom Bossert, who at the time of the attack was the most senior cybersecurity focused official in the US government. During the attack initiated on 27 June 2017, the radiation monitoring system at Ukraine's Chernobyl Nuclear Power Plant went offline. Several Ukrainian ministries, banks and metro systems were also affected. It is said to have been the most destructive cyberattack ever. Among those affected elsewhere included British advertising company WPP, Maersk Line, American pharmaceutical company Merck & Co. (internationally doing business as MSD), Russian oil company Rosneft (its oil production was unaffected), multinational law firm DLA Piper, French construction company Saint-Gobain and its retail and subsidiary outlets in Estonia, British consumer goods company Reckitt Benckiser, German personal care company Beiersdorf, German logistics company DHL, United States food company Mondelez International, and American hospital operator Heritage Valley Health System. The Cadbury's Chocolate Factory in Hobart, Tasmania, is the first company in Australia to be affected by Petya. On 28 June 2017, JNPT, India's largest container port, had reportedly been affected, with all operations coming to a standstill. Princeton Community Hospital in rural West Virginia will scrap and replace its entire computer network on its path to recovery. The business interruption to Maersk, the world's largest container ship and supply vessel operator, was estimated between $200m and $300m in lost
