Officials announced the U.S. weather network was breached late September, forcing cybersecurity teams to temporarily cut off access to the data critical for disaster planning, aviation and shipping, reported the Washington Post.
Reports state Chinese hackers are allegedly behind the incident, although the National Oceanic and Atmospheric Administration (NOAA) did not discuss the suspected source of the attack.
In a statement released Wednesday, NOAA said it implemented incident response immediately after the attack was recognized and all systems have since been restored.
“The unscheduled maintenance impacts were temporary and all services have been fully restored,” said NOAA Spokesman Scott Smullen. “These effects did not prevent us from delivering forecasts to the public.”
It is still unclear whether the compromise affected classified information, however, the agency noted further investigation of the incident is underway.
The news of NOAA’s breach follows the recent announcement of a similar incident involving the U.S. Postal Service, which confirmed on Monday its computer networks had been compromised. China was also suspected to stand behind the attack.
The breach exposed the personal information of all 800,000 employees, including names, social security numbers, phone numbers, addresses and dates of employment, as well some information of customers who contacted the USPS call center between Jan. 1 and Aug. 16.
The American Postal Workers Union (APWU) has reportedly filed charges against the Postal Service for failing to consult with the group prior to announcing the breach.
