Russian airline Aeroflot was forced to cancel more than 50 round-trip flights on Monday, disrupting travel across the world's biggest country, as two pro-Ukraine hacking groups claimed to have inflicted a crippling cyberattack.

A cyberattack on Russian airline Aeroflot has caused a major outage, leading to over 100 flight cancellations and delays.

The hack may have been part of a campaign to disrupt the sense of normalcy Russians have mostly enjoyed since the start of the war.
