Date: 13 DEC 2023
The cyberattack on Kyivstar, Ukraine's largest telecommunications provider, on December 12, 2023, coinciding with a massive airstrike involving a combination of missiles and drones, represents a complex and concerning escalation in hybrid warfare tactics. This incident highlights the integration of conventional military strikes with cyber warfare, underscoring the evolving nature of modern conflicts.
In the case of Kyivstar, the cyberattack led to significant service disruptions for approximately 25 million users. This impact is particularly critical considering the vital role of telecommunications in disseminating air attack alerts, thereby directly affecting the safety and security of millions of individuals. The decision by Kyivstar's operators to shut down the system to prevent further damage, while necessary, exacerbated the challenge of maintaining effective communication during a time of crisis.
As of December 13, 2023, the situation remains precarious with the roaming network offline and only limited access to landline services. The uncertainty regarding the timeline for full restoration of services adds to the complexity of the situation. While Kyivstar officials have assured that personal data of users has not been compromised, the overall impact of the cyberattack, combined with the physical airstrikes, creates a multifaceted security challenge.
The attribution of the cyberattack is still under investigation. Although a self-proclaimed Pro-Russian 'hacktivist' group has claimed responsibility, Ukrainian officials suggest the involvement of Russian security services. This ambiguity in attribution is a common characteristic of cyber warfare, often leading to challenges in formulating appropriate responses and strategies for prevention and retaliation.
From a risk management perspective, this incident underscores the importance of integrating emergency and contingency communications resources and planning is a critical aspect of risk management, particularly in the context of hybrid threats, as exemplified by the cyberattack on Kyivstar amidst physical military strikes.
For organizations operating in regions with heightened risk profiles, such as Ukraine, a comprehensive approach that integrates cybersecurity with traditional security measures is essential to mitigate the risks associated with such hybrid warfare tactics.
Infrastructure and Utilities
The cyberattack has led to the deprivation of internet, navigation, communication, and ATM services for more than 25 million Ukrainian citizens. Although it is reported to have no direct impact on the military, the compromise of public safety is evident as Kyivstar, responsible for disseminating Air Attack Alerts to a significant portion of the population, faces disruptions. Business and financial hubs have reported substantial service disruptions owing to internet outages and communication restrictions, with some banks noting a loss of ATM services.
National and International Response
Ukraine's state cybersecurity agency (SSSCIP) stated that "relevant services," including Ukraine's computer emergency response team (CERT-UA), are actively investigating the incident. Kyivstar parent company, Netherlands-based VEON, confirmed in a news release that the incident was indeed a "hacker attack." and confirmed that they are working with international law enforcement agencies to identify those responsible for the attack.
Kyivstar CEO confirmed that hackers had penetrated "a part of the operator's internal systems." The company is working to implement "duplicate systems" to address the breach. The decision to completely shut down the Kyivstar system was a collaborative effort between Ukrainian security forces and the operator, aimed at "localizing" the impact of the cyberattack. Kyivstar hopes to have restored landline services by the end of 13 December with other services restored in the coming days.
The impact on air attack alarms has been addressed in the short term by the use of loud speakers to relay warnings to the public, however many citizens have been changing to Vodafone to provide alternative connectivity.
Kyivstar verified that hackers have previously attempted to target the company, but this marks the first instance of them successfully disrupting services. While cyber attacks on Ukrainian infrastructure are a common occurrence, the majority are inconsequential, with services either unaffected or quickly restored. In the initial stages of the Russian invasion in February 2022, ViaSat experienced a cyber attack that disabled thousands of satellite internet modems throughout Europe, leading to significant communication losses across Ukraine.
In light of the increasing cyber threats in the region, it is imperative for both organizations and individuals who are operating, journeying, or living within the vicinity to exercise heightened vigilance in their digital security measures. This encompasses a comprehensive approach to protecting sensitive data and information resources from potential breaches.
To enhance preparedness, all organizations with operations and personnel in Ukraine are strongly encouraged to rigorously update their existing communication contingency plans. This should include regular reviews and revisions to ensure that emergency protocols are robust and can withstand the challenges posed by cyber threats. Additionally, there is an emphasis on bolstering security awareness across all levels of operation. Personnel should be committed to continuous education and training in cybersecurity best practices, thus fostering a culture of proactive defense against cyber incursions.
In anticipation of possible disruptions to standard communication channels due to cyber attacks, it is advisable to explore and implement alternative communication methods. This could involve investing in satellite communication devices that provide reliable connectivity independent of terrestrial networks. Furthermore, securing additional SIM cards or engaging alternate cellular data providers can offer valuable redundancy. Specifically, acquiring Vodafone SIM cards has been identified as a prudent strategy for maintaining uninterrupted network access. These SIM cards can serve as an effective backup network option, ensuring that communication remains possible even in the event of targeted cyber attacks on primary service providers.
By taking a few of the above precautionary steps, organizations and individuals can significantly mitigate the risk of cyber threats, and conflict-initiated service interruptions, and take steps to ensure the continuity of their operations and personal safety in an increasingly digitally reliant world.
Cyber Safety Guidelines for Personnel
Despite the recent cyber attacks being aimed against national infrastructure, individuals and companies working in Ukraine are advised to continue taking measures to safeguard against cyber attacks and service interruptions and should consider implementing the following cybersecurity measures:
Employee Training: Conduct regular cybersecurity awareness training for staff to educate them about potential threats, phishing attacks, and safe online practices. Awareness is often considered the first line of defense in cybersecurity.
