Ukrainian hacker sentenced in US to 41 months in prison

Worsening tensions: The attack on public and financial websites could be coming from Russia.

A Ukrainian who administered two online hacking forums was sentenced on Feb 16 to 41 months in prison for using more than 13,000 computers to steal log-in and credit card data, US prosecutors said.

Sergey Vovnenko, whose aliases included "Flycracker" and "Darklife", was sentenced by US District Judge Esther Salas in Newark, New Jersey, after pleading guilty last year to aggravated identity theft and conspiracy to commit wire fraud.
