KYIV (Reuters) - Hackers who launched strikes against Ukrainian government websites appear to have used the software administration rights of a third party company that developed the sites, a top Ukrainian security official told Reuters on Friday.

Serhiy Demedyuk, the deputy secretary of the national security and defence council, said Ukraine was working to establish who obtained such access, whether it was done externally or through an insider.
