From a blog post by Microsoft: On June 27, 2017 reports of a ransomware infection began spreading across Europe. We saw the first infections in Ukraine, where more than 12,500 machines encountered the threat. We then observed infections in another 64 countries, including Belgium, Brazil, Germany, Russia, and the United States. The new ransomware has worm capabilities, which allows it to move laterally across infected networks. Based on our investigation, this new ransomware shares similar codes and is a new variant of Ransom:Win32/Petya. This new strain of ransomware, however, is more sophisticated. […] Initial infection appears to involve a software supply-chain threat involving the Ukrainian company M.E.Doc, which develops tax accounting software, MEDoc. Although this vector was speculated at length by news media and security researchers — including Ukraine’s own Cyber Police — there was only circumstantial evidence for this vector. Microsoft now has evidence that a few active infections of the ransomware initially started from the legitimate MEDoc updater process. A New York Times reports how rest of the world is dealing with Petya. From the article: A fuller picture of the impact will probably emerge in the coming days. But companies and government offices worldwide appeared less affected than the WannaCry attack, notably in places like China, which was hard hit in May. Reports from Asia suggested that many of the companies hit were the local arms of European and American companies struck on Tuesday. In Mumbai, India, a port terminal operated by A.P. Moller-Maersk, the Danish shipping giant, was shut after it disclosed that it had been hit by the malware. In a statement, Indian port authorities said they were taking steps to relieve congestion, such as finding places to park stranded cargo. The attack shut the terminal down on Tuesday afternoon. On the Australian island of Tasmania, computers in a Cadbury chocolate factory owned by Mondelez International, the American food company, displayed the ransomware message, according to the local news media.
