The Port of Houston thwarted an attempted cyberattack last month, officials from the facility confirmed on Thursday.
"The Port of Houston Authority (Port Houston) successfully defended itself against a cybersecurity attack in August," port officials said in a statement. "Port Houston followed its Facilities Security Plan in doing so, as guided under the Maritime Transportation Security Act (MTSA), and no operational data or systems were impacted as a result."
The port authority did not provide further details about the attempted hack. The hackers attempted to breach computer systems by exploiting a password management service called ManageEngine ADSelfService Plus, the Associated Press reported.
