The metropolitan prosecutor’s office has filed an appeal against the decision made by the Khoroshevsky court regarding the selection of a preventive measure for the CEO of Siren-Travel JSC, Igor Roitman, and Alexander Kalchuk. The top managers of Leonardo are being accused of unlawfully impacting the critical information infrastructure of the Russian Federation, a violation under part 5 of article 274.1 of the Criminal Code of the Russian Federation.
On April 5, the court decided not to send Igor Roitman and Alexander Kalchuk to the pre-trial detention center as requested by the investigation. Instead, they were placed under restrictions until June 4.
Specifically, Roitman and Kalchuk are prohibited from leaving their homes between 18:00 to 8:00, communicating with witnesses in the case, and visiting the Siren-Radel office. They are only allowed to use communication tools, including the Internet, to interact with their defense attorneys, the investigation team, and emergency services.
Prior to this decision, the investigation had requested custody for the accused, but the court opted for a less severe preventive measure. Igor Roitman and Alexander Kalchuk were then released from the courtroom.
In early April, the Siren-Rodel office on Leningradsky Prospekt underwent searches conducted by the Ministry of Internal Affairs, the FSB, and the Russian Guard. Sources familiar with the situation revealed that the law enforcement actions were related to hacker attacks on the IT infrastructure of the Russian ticket reservation system, which Siren-Rodel had experienced the previous fall. The company had reported these incidents to law enforcement agencies in relation to information security breaches and had fully cooperated by providing access to all relevant documents and data for the investigation. As part of their inquiries, experts examined the company’s equipment to identify system vulnerabilities and seized documentation leading to the subsequent detainment of Roitman and Kalchuk.
In September 2023, the Leonardo reservation system, developed by Sirena-Travel, was targeted by a massive hacker attack. This attack resulted in disruptions to the registration processes for passengers of various airlines including Aeroflot, Russia, Azur Air, Victory, and Ural Airlines. The disruptions were attributed to a large-scale DDOS attack originating from overseas according to Rostec officials.
