Ukraine says Russian state hackers using new viruses for attacks

KIEV (Reuters) - State-sponsored Russian hackers are using a new type of virus designed to attack critical Ukrainian infrastructure such as the power grid and financial system, a senior Ukrainian state security official said on Wednesday.

Called "telebots", the new viruses are not like ordinary malware, designed for example to steal personal data, but are tailor-made to attack specific institutions, Oleksandr Tkachuk, Ukraine's security service chief of staff, said at a televised news conference.
