What do you think happens when a major airline’s IT systems are completely dismantled by hackers? The implications can be significant, not just for the company but for travelers and the broader aviation industry as well. In this article, we’re going to delve into the recent cyber attack that allegedly destroyed Aeroflot Airlines’ IT infrastructure. Let’s break down the details and understand what this means for everyone involved.

The Attack: Overview and Impact
In July 2025, Aeroflot Airlines, one of the oldest airlines in the world, became the target of a cyber attack that has left its operations severely impaired. Pro-Ukraine hackers, known as “Silent Crow” and “Cyber Partisans BY,” claimed responsibility for a year-long operation that culminated in the assault on the airline’s IT systems. They allege that they accessed critical systems and caused extensive damage, including the loss of thousands of servers and sensitive data.
On July 27, 2025, the hackers activated a “wiper” payload that effectively destroyed around 7,000 servers, impacting vital operations like flight scheduling and internal communications. By the following morning, Aeroflot faced operational paralysis, canceling numerous flights and affecting numerous passengers.
Timeline of the Attack
Understanding the timeline of events is crucial in grasping the scope and scale of this cyber incident. Let’s take a look at the specific milestones that marked this breach:
Mid-2024
The attackers initially gained access to Aeroflot’s corporate network around mid-2024, employing techniques such as targeted phishing and exploiting zero-day vulnerabilities. Gradually, they escalated their access through various system layers, setting the stage for further infiltration.
Spring 2025
By Spring 2025, the hacktivist groups had achieved Tier-0 access, a critical level that allows administrative control over essential systems, including booking and communication platforms. At this point, the hackers had exfiltrated approximately 12 TB of databases, 8 TB of file shares, and 2 TB of email stores.
July 27-28, 2025: The Strike
The coordinated attack peaked on the night of July 27, when the wiper payload was launched. This action effectively erased vast quantities of critical information from 122 VMware ESXi hosts. As a direct result, approximately 7,000 physical and virtual servers were rendered inoperable.
On July 28, Aeroflot publicly acknowledged an “information-system failure” as they struggled to manage the fallout. The repercussions were immediate and widespread.
Key Events Summary
| Date/Time | Milestone/Impact |
|---|---|
| Mid-2024 | Initial access gained through phishing and zero-day exploits. Establishment of persistent access. |
| Spring 2025 | Escalation to Tier-0 level. Administrative control gained. |
| July 27, 2025 | Wiper payload activated, erasing approximately 7,000 servers. |
| July 28, 2025 | First public statement issued, 42 flights canceled as the airline begins to realize the extent of the failure. |
Details of the Breach
The depth of information compromised during this breach is staggering. The hackers claimed they accessed many core systems within Aeroflot’s IT environment. Let’s break this down further.
Critical Systems Compromised
The attackers reportedly breached several essential platforms, including:
- Sabre: A major global distribution system used for airline reservations.
- Sirax: A system used for ticketing and inventory.
- SharePoint: Utilized for document management and team collaboration.
- Exchange: Microsoft’s email server, which handles internal communications.
- CRM: Systems that manage Aeroflot’s customer relationships.
- ERP: Enterprise Resource Planning systems critical for operational efficiency.
Gaining access to these systems allowed hackers to gather sensitive data, including historical flight databases, personally identifiable information (PII), and a treasure trove of internal communications.
Data Loss Estimates
As stated earlier, the hackers managed to exfiltrate around 20-22 TB of data before the destructive payload was executed. This scale of data loss represents not just a logistical nightmare but also raises serious concerns over data privacy.
Consequences for Aeroflot
The ramifications of this cyber attack are profound, not just from a technical standpoint but also in terms of business operations and public confidence.
Operational Shutdown
The immediate response from Aeroflot involved canceling a significant number of domestic and regional flights. Within hours, the airline reported that 42 flights had been grounded, which quickly escalated to 49. The sheer number of stranded travelers at Moscow’s Sheremetyevo Airport reflects the chaos caused by this incident.
Financial Impact
From a financial perspective, the impact has already been felt on the Moscow Exchange, where Aeroflot’s stock price dropped by over 4% immediately after the attack. Security analysts believe the recovery cost could run into “tens of millions of dollars,” as rebuilding critical infrastructure and implementing more robust cybersecurity measures will be a gargantuan task.
Legal and Regulatory Scrutiny
Following the attack, the Russian Prosecutor General’s office launched a criminal investigation under Article 272 for “unauthorized access.” This legal inquiry has implications not just for the attackers, but also for Aeroflot as they may face intense scrutiny regarding their data security practices.
Broader Implications for the Aviation Industry
The stakes extend beyond Aeroflot. The aviation sector as a whole must consider the broader implications of such attacks, especially in light of ongoing geopolitical tensions.
Cybersecurity in Aviation
Airlines globally are now reevaluating their cybersecurity protocols. With the rise in digital threats, the definition of operational resilience needs to be rethought, ensuring that systems can recover quickly from similar attacks. The recently demonstrated vulnerabilities also highlight the necessity for governmental and industry-wide standards for cybersecurity in aviation.
Geopolitical Considerations
This incident must also be viewed in the context of the ongoing conflict between Russia and Ukraine. The hacktivist groups’ statements suggest that their motivations are tied to the geopolitical landscape. As such, it raises questions about the ethics and legality of cyber warfare and what boundaries, if any, exist.
Moving Forward: What Can Be Done?
Given the lessons learned from the Aeroflot incident, it is imperative that organizations, especially those in high-risk sectors like aviation, adopt more stringent cybersecurity measures. Here are some best practices:
Enhanced Employee Training
Phishing attacks were central to how the attackers initially gained access. Regular training sessions to keep employees vigilant against social engineering tactics can mitigate risks.
Zero Trust Architecture
Moving away from traditional security models towards a Zero Trust Architecture can greatly enhance security posture. This approach assumes that threats could exist both outside and inside the company and enforces strict access controls.
Regular Security Audits
Conducting regular security audits and penetration testing can identify vulnerabilities before they are exploited. Organizations can better prepare themselves by staying ahead of potential threats.
Incident Response Planning
Having a comprehensive incident response plan is vital. By preparing for potential breaches, companies can reduce recovery time significantly. This includes understanding key contacts, protocols for public communication, and recovery steps.
Investment in Cybersecurity
Finally, organizations must see cybersecurity not just as a cost but an essential investment. Whether through technology or training, the value lies in safeguarding not only company assets but also customer trust.
Conclusion
The cyber attack on Aeroflot Airlines serves as a stark reminder of the vulnerabilities that exist in today’s digital landscape. As you observe the unfolding consequences, consider how all organizations—especially those integral to the global infrastructure—must fortify their defenses against ever-evolving threats. By learning from such incidents and implementing robust security measures, we can hope to mitigate future risks and ensure a safer digital environment for everyone.
