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.

Russia's national airline, Aeroflot, said it had cancelled dozens of flights after pro-Ukrainian hackers claimed an attack on the carrier's IT systems. A statement from hacking group Silent Crow said it carried out the attack with the help of a Belarusian group Cyberpartisans.

Russian airline Aeroflot cancelled nearly 50 flights on the morning of 28 July due to a malfunction in its information systems. Pro-Ukrainian hacker groups Silent Crow and Cyber Partisans BY have claimed responsibility.
