KYIV (Reuters) -Ukraine's biggest mobile operator Kyivstar said on Wednesday it had restored all services within the country and abroad a week after a massive cyber attack damaged IT infrastructure and affected air raid alert systems in some parts of the country.
Services of the company, which counts more than half of Ukraine's population as mobile subscribers, were knocked out after hackers used an employee's compromised account to carry out the attack.
