Two pro-Ukraine hacking groups claimed to have carried out a year-long operation to penetrate Aeroflot's network

Russian airline Aeroflot cancelled dozens more flights on Tuesday but said it had now stabilised its schedule after a major cyberattack a day earlier, and the transport ministry said the issue had been resolved.

Russian prosecutor said it opened a criminal investigation into the cyberattack targeting Aeroflot, the largest airline in Russia.
