Attackers say they hitc 7,000 servers, extracted data on passengers and employees and gained control over the personal computers of staff.
Russian airline Aeroflot has cancelled dozens of flights after a major cyber-attack on Monday.
According to Reuters, the airline has stabilised its schedule after two pro-Ukraine hacking groups claimed on Monday to have carried out a year-long operation to penetrate Aeroflot's network.
The groups said they had crippled 7,000 servers, extracted data on passengers and employees and gained control over the personal computers of staff, including senior managers.
While Aeroflot has not provided specifics amid ongoing efforts to immediately restore impacted systems, such an incident was purported to have been conducted by pro-Ukrainian hacktivist operation Silent Crow and the Belarusian Cyber-Partisans.
