“For this neglect, the people in this case will face criminal responsibility.”
In a separate interview with Reuters, the father and daughter team who run Intellect Service said they were not responsible.
“What has been established in these days, when no one slept and only worked? We studied and analysed our product for signs of hacking – it is not infected with a virus and everything is fine, it is safe,” said Olesya Linnik, managing partner at Intellect Service.
“The update package, which was sent out long before the virus was spread, we checked it 100 times and everything is fine.”
Security experts, including Microsoft, Cisco and Symantec, said that they all have evidence that the malware was spread via an update to the tax software program MeDoc.
It is believed that around 80% of companies in Ukraine use the software, which allows clients to send and discuss financial documents internally as well as file them with the government’s tax department.
Ukraine police said that the family could face criminal charges if it is confirmed that they knew about the infection but took no action.
