FireEye, a cybersecurity firm, revealed last week that unknown parties had penetrated its network and that its clients, including the US Government, were at risk. Bruce Schneier has technical details about the attack. Former Homeland Security Adviser Thomas Bossert lays out the scope of it:
The attackers gained access to SolarWinds software before updates of that software were made available to its customers. Unsuspecting customers then downloaded a corrupted version of the software, which included a hidden back door that gave hackers access to the victim’s network.
This is what is called a supply-chain attack, meaning the pathway into the target networks relies on access to a supplier. Supply-chain attacks require significant resources and sometimes years to execute. They are almost always the product of a nation-state. Evidence in the SolarWinds attack points to the Russian intelligence agency known as the S.V.R., whose tradecraft is among the most advanced in the world.
According to SolarWinds S.E.C. filings, the malware was on the software from March to June. The number of organizations that downloaded the corrupted update could be as many as 18,000, which includes most federal government unclassified networks and more than 425 Fortune 500 companies.
The magnitude of this ongoing attack is hard to overstate.
The Russians have had access to a considerable number of important and sensitive networks for six to nine months. The Russian S.V.R. will surely have used its access to further exploit and gain administrative control over the networks it considered priority targets. For those targets, the hackers will have long ago moved past their entry point, covered their tracks and gained what experts call “persistent access,” meaning the ability to infiltrate and control networks in a way that is hard to detect or remove.
The logical conclusion is that we must act as if the Russian government has control of all the networks it has penetrated.
Now, if only we had an administration that believed its experts and a majority party in the Senate that would pass a Defense Reauthorization Bill...
