MOSCOW, July 28 (Reuters) - The Kremlin on Monday called

reports of a cyberattack attack on Russian flag carrier

Aeroflot's internal systems worrying and said it wanted more

information about the situation.

Aeroflot said on Monday that it had cancelled up

to 50 flights after reporting a failure in its information

systems. A pro-Ukrainian hacking group called Silent Crow

claimed responsibility for the attack.

"The information we read in the public domain is quite

alarming," Kremlin spokesman Dmitry Peskov told reporters.

"The threat of hacking is a threat that remains for all

large companies that provide services to the public. We will, of

course, (seek to) clarify this information and wait for the

relevant explanations."
