KIEV, July 4 (Reuters) - Ukrainian police have seized the computer servers of Ukrainian accounting software firm M.E.Doc as part of an investigation into last week's cyber attack, Cyber Police Chief Serhiy Demedyuk told Reuters on Tuesday.
Ukrainian officials and security firms have said some of the initial infections occurred when malware was transmitted via a malicious update issued by M.E.Doc, which is Ukraine's most popular accounting software.
M.E.Doc's developers told Reuters on Monday their servers were not compromised by the hackers and that updates it issued to clients were not infected. They were not immediately available for comment on Tuesday. (Reporting by Pavel Polityuk; Writing by Jack Stubbs; Editing by Matthias Williams)
