The ransomware was called Petya and the updated version Petrwrap.”Andrei Barysevich, a spokesman for security firm Recorded Future, told the BBC that it had seen the malware for sale on many forums over the last 12 months.”It only costs $28 (£22) on the forums,” he said. “But we are not sure if they used the latest version or a new variant of it.Mr Barysevich said the attacks would not stop because cyber-thieves found them too lucrative. “A South Korean hosting firm just paid $1m to get their data back and that’s a huge incentive,” he said. “It’s the biggest incentive you could offer to a cyber-criminal.”Network downOthers reporting problems include the Ukrainian central bank, the aircraft manufacturer Antonov, and two postal services.Russian oil producer Rosneft and Danish shipping company Maersk also say they face disruption, including its offices in the UK and Ireland.”We can confirm that Maersk IT systems are down across multiple sites and business units due to a cyber-attack,” the Copenhagen-headquartered firm said via Twitter.”We continue to assess the situation. The safety of our employees, our operations and customers’ business is our top priority.”
Spanish media reports that the offices of large multinationals such as food giant Mondelez and legal firm DLA Piper have suffered attacks.And French construction materials company St Gobain has said that it is also fallen victim.The attacks come two months after another global ransomware assault, known as Wannacry, which caused major problems for the UK’s National Health Service.
Ukraine seems to have been particularly badly hit this time round.Reports suggest that the Kiev metro system has stopped accepting payment cards while several chains of petrol stations have suspended operations.Ukraine’s deputy prime minister has tweeted a picture appearing to show government systems have been affected.His caption reads: “Ta-daaa! Network is down at the Cabinet of Minister’s secretariat.”
