New submitter Pravetz-82 shares a report from Politico: A cyberattack on Russian state-owned flagship carrier Aeroflot caused a mass outage to the company's computer systems on Monday, Russia's prosecutor's office said, forcing the airline to cancel more than 100 flights and delay others. Ukrainian hacker group Silent Crow and Belarusian hacker activist group the Belarus Cyber-Partisans, which opposes the rule of Belarusian President Alexander Lukashenko, claimed responsibility for the cyberattack. Images shared on social media showed hundreds of delayed passengers crowding Moscow's Sheremetyevo airport, where Aeroflot is based. The outage also disrupted flights operated by Aeroflot's subsidiaries, Rossiya and Pobeda. While most of the flights affected were domestic, the disruption also led to cancellations for some international flights to Belarus, Armenia and Uzbekistan. Silent Crow claimed it had accessed Aeroflot's corporate network for a year, copying customer and internal data, including audio recordings of phone calls, data from the company's own surveillance on employees and other intercepted communications. "All of these resources are now inaccessible or destroyed and restoring them will possibly require tens of millions of dollars. The damage is strategic," the channel purporting to be the Silent Crow group wrote on Telegram. There was no way to independently verify its claims. The same channel also shared screenshots that appeared to show Aeroflot's internal IT systems, and insinuated that Silent Crow could begin sharing the data it had seized in the coming days. "The personal data of all Russians who have ever flown with Aeroflot have now also gone on a trip -- albeit without luggage and to the same destination," it said. The Belarus Cyber-Partisans told The Associated Press that they had hoped to "deliver a crushing blow." Russia's Prosecutor's Office said it had opened a criminal investigation. Meanwhile, Kremlin spokesperson Dmitry Peskov called reports of the cyberattack "quite alarming," adding that "the hacker threat is a threat that remains for all large companies providing services to the general public."Read more of this story at Slashdot.
