When we think of a "cyberattack," we often picture hackers targeting sensitive information from individuals and businesses. However, it's not something we usually associate with the aviation industry or the disruption of airport systems. Unfortunately, on August 24, 2024, that reality became all too clear as a cyberattack struck Sea-Tac Airport, impacting not only the operations of the facility but also the travelers relying on its services. In this blog, we will discuss what transpired during the attack and identify those responsible. We’ll also provide an update on the situation, detect vulnerabilities that may have led to the breach, and outline the current solutions being implemented to enhance security.
What Happened:
What initially appeared to be simple system outages soon escalated into a significant cybersecurity incident—a ransomware attack targeting Sea-Tac Airport Systems. The attackers are identified as the Rhysida group. This incident affected multiple services, including passenger display boards, Wi-Fi, check-in kiosks, ticketing, baggage handling, and reserved parking. Additionally, it impacted the airport's flySEA mobile app and the Port of Seattle website. Travelers encountered handwritten signs and boards at baggage claim and ticket counters to help guide them.
Who’s Responsible?
The Rhysida ransomware gang is a relatively new group of cybercriminals known for their sophisticated ransomware attacks. They utilize advanced tactics, such as phishing and exploiting vulnerabilities, to gain unauthorized access to networks. Operating on the dark web, they promote their capabilities and negotiate ransom payments with victims. Their targets span various sectors, including healthcare, finance, and transportation, highlighting the increasing trend of ransomware attacks on critical infrastructure. In the case of the Sea-Tac attack, they likely employed these same methods to breach the airport's systems.
Potential Weak Points:
Here are potential weak points that may have been exploited:
- Weak Password Hygiene: Poor password practices can leave systems dangerously exposed, making it easier for attackers to gain unauthorized access.
- Insufficient Employee Training: A lack of comprehensive training can leave employees vulnerable to social engineering tactics, increasing the risk of falling victim to phishing and other attacks.
- Communication Breakdowns: Ineffective communication within teams can hinder timely responses to threats, allowing attacks to escalate unchecked.
The Update:
As of September 11, flight and baggage information displays are now showing the schedules for all airlines throughout the SEA Airport terminal. Travelers can once again enjoy their usual experience at SEA, with Wi-Fi restored, displays operational, and all check-in and ticketing systems fully functional. Recent updates indicate that the attackers demanded $6 million in bitcoin for the stolen documents, which they have since released on the dark web (Sept. 16th). Sea-Tac refused to entertain the ransom offer. Lance Lyttle, the port’s managing director of aviation reports that “On Monday, they posted on their dark website a copy of eight files stolen from Port systems and are seeking 100 bitcoin to buy the data,”. What the documents were has not been disclosed yet, and the airport will contact any individuals whose personal information could have potentially been stolen.
Contingency Response Plan:
- Restoring and rebuilding systems
- Taking additional steps to enhance existing controls
- Strengthening identity management protocols
- Improving authentication protocols
- Enhancing monitoring of the IT environment
