Just a week after the Port of Barcelona was disrupted by a cyberattack, the Port of San Diego is announcing similar news, ZDNet reports.

In a statement yesterday on the Port’s website, Randa Coniglio, CEO for the Port of San Diego, said, “Port employees are currently at work but have limited functionality, which may have temporary impacts on service to the public, especially in the areas of park permits, public records requests, and business services.”

According to The San Diego Union-Tribune, The Port of San Diego is responsible for 34 miles of property along San Diego Bay and includes the San Diego Harbor Police Department, which was also impacted. Disruptions first began to be reported on Tuesday. While investigations continue, alternative systems are being used.

In addition to Barcelona and San Diego, ZDNet notes that a ransomware attack also was reported in Long Beach in July. It was said to have affected Long Beach Port, and ended up being limited to the internal network of China Ocean Shipping Company (COSCO).

“With three disruptive cyber-attacks reported by three ports in two months, some might wonder if a threat group isn’t targeting ports intentionally. This isn’t a surprise, as ports handle a huge amount of business, and any disturbance can lead to serious financial losses,” reports ZDNet. Interestingly, one of the first organizations to sound the alarm as NotPetya was unleashed was global shipping company Maersk.
