A cyberspying operation targeting key Russian institutions has been uncovered by the country's domestic intelligence service FSB, the agency reported Saturday.
The hacking attack focused on about 20 institutions belonging to the Russian government, scientific institutes, military facilities and defence companies, it reported.
The report comes just days after Russian computer criminals were accused of hacking into the computers of the US Democratic Party, unearthing party documents that resulted in the party's chairwoman stepping down.
The software used in the hacking attack was very similar to that used in other "notable cases of cyberespionage," said the FSB.
The agency said all targets had been notified, the security gaps plugged and any consequences minimized. No further details were offered.
