In retaliation for a cyber attack by Russia against the Ukrainian telecom giant Kyivstar, hackers associated with Ukraine's primary intelligence agency have infiltrated the computer systems of a Moscow-based internet provider, Reuters reports.

The hackers, allegedly linked to Ukraine's spy agency, erased 20 terabytes of data from M9 Telecom, a relatively small Russian internet and TV provider, resulting in some Moscow residents experiencing internet service disruptions.

Despite the hacking group's assertion that the company's website had been destroyed, the extent of the successful breach could not be independently verified by Reuters.
