Invalid Date, RUSSIAN spies reportedly hacked Microsoft and infiltrated a US nuclear weapons stockpile as part of a nine-month "virtual invasion" by Moscow. The malware used in the breach - which poses a "grave threat" to America - was "isolated to business networks only” and has not affected US national security, an Energy Department spokeswoman said on Friday. 19 19 Hackers used various techniques, including the corruption of updates from network management app SolarWinds. The SolarWinds hack may have impacted thousands of companies and government agencies, the DHS revealed. According to CISA, not all networks were hacked, but everyone should take the hack as no one is safe - even if the organizations used older versions of the SolarWinds software.
