The defence ministry’s statement came in the wake of a report by the onet.pl website warning of “a massive leak of army data,” the state PAP news agency reported.
In an article published on Friday, onet.pl said that files with “over 1.7 million records listing Polish Armed Forces assets" including armaments had been leaked online.
The website claimed that the leak, confirmed by two independent sources inside Poland’s security services, included information “of extreme value” to foreign intelligence agencies.
Onet.pl quoted a cybersecurity expert as saying that the record had already been downloaded by users from about a dozen countries, including Russia and China.
Meanwhile, a group of opposition lawmakers asked the central auditing office NIK to investigate the matter, public broadcaster Polish Radio’s IAR news agency reported.
'Publicly available information only'
In a statement issued in response to the report, the Polish defence ministry said that “the publication of the data does not pose a risk to the security of the state or the functioning of the Polish Armed Forces.”
“Upon verification of the matter by the security services, we would like to inform you that the catalogue found online … was being operated by the Support Inspectorate (IW), which is responsible for the Polish Army’s purchases,” the statement said.
“The database contains publicly available information only,” the Polish defence ministry added, as quoted by the PAP news agency.
Defence Minister Mariusz Błaszczak said in a Twitter post that "no secret information has been leaked" that could compromise national security.
"Poland is safe," he tweeted.
