The Port of Seattle, which also operates the Seattle-Tacoma International Airport, reported a potential cyberattack that disrupted its systems. The port first noted the outages on Saturday morning through social media, with the airport subsequently posting about experiencing certain system outages "indicating a possible cyberattack." Late Saturday evening, the airport confirmed ongoing issues: "There is not an estimated time for return and Port teams continue to work to restore full service."

The Port of Seattle, including SEA Airport, continues to experience system outages. There is no estimated timeframe for restoration, with Port teams working tirelessly to regain full service.

As of Sunday morning Pacific time, the Port of Seattle’s public-facing web infrastructure—comprising its website and other online services—remained offline or partially operational, according to a TechCrunch review of its DNS records. Earlier this year, during the Biden administration, the U.S. government issued an executive order aimed at enhancing cybersecurity measures for ports.

This incident follows less than a month after a CrowdStrike software update caused a global IT outage, resulting in flight cancellations and delays across the skies. Additional details about the nature of the potential cyberattack are still under investigation.


Background on Cybersecurity Measures

The Port of Seattle has been actively working to strengthen its cybersecurity protocols following this incident. Earlier this year, during the Biden administration, the U.S. government issued an executive order designed to improve the cybersecurity resilience of ports and other critical infrastructure.

The Impact of Previous Incidents

Prior to this event, the port had already faced challenges in 2023 when aCrowdStrike software update caused widespread disruptions. This incident underscored the importance of robust cybersecurity measures for protecting sensitive systems and ensuring smooth operations at critical facilities like airports and seaports.

Response from Airport Authority

The Seattle-Tacoma International Airport has been closely monitoring the situation and has taken steps to mitigate the impact on travelers. The airport encourages passengers to use airline apps for boarding passes and baggage tags, as well as to allow extra time when approaching their gates. Updates will be provided through official channels as more information becomes available.

Public Reaction

The incident has sparked concerns about the port’s ability to protect its systems from cyber threats. Many onlookers have expressed skepticism about whether such a large-scale cyberattack is feasible, given the port’s limited resources and expertise in cybersecurity.

Lessons Learned

This incident serves as a reminder of the potential risks posed by cyberattacks on critical infrastructure. While the immediate impact has been significant, ongoing efforts to enhance security measures will help mitigate future disruptions.
