Solorigate: SolarWinds Orion Compromise Overview - Security Boulevard

SBN Solorigate: SolarWinds Orion Compromise Overview

On 13th December 2020, it came to light SolarWinds IT systems were compromised by hackers between March 2020 and June 2020. SolarWinds provides software to help organisations manage their IT networking infrastructure. The attackers exploited their SolarWinds IT access to covertly insert a vulnerability, coined ‘Solorigate’ or ‘Sunburst’, within the SolarWinds Orion platform software builds. 
The following SolarWinds Orion versions are considered to be compromised. 
  • Orion Platform 2019.4 HF5, version 2019.4.5200.9083
  • Orion Platform 2020.2 RC1, version 2020.2.100.12219
  • Orion Platform 2020.2 RC2, version 2020.2.5200.12394
  • Orion Platform 2020.2, 2020.2 HF1, version 2020.2.5300.12432
The vulnerability within these ‘tainted’ SolarWinds Orion versions permits an attacker to compromise the server on which the SolarWinds Orion product is installed and runs.  Given that SolarWinds is a popular network traffic monitoring product, thousands of organisations are said to be impacted by a potential hidden ‘backdoor’ into their internal networks, which is open to be exploited by malicious hackers, granting them remote access to their internal IT systems and confidential data.  Organisations with the compromised versions of SolarWinds Orion present should immediately disconnect the software’s host server from their network, and conduct a digital forensic investigation to determine if their IT systems were remotely compromised.
How to Update SolarWinds Orion to a Safe Version

Upgrading to Orion Platform version 2020.2.1 HF 2 ensures the platform is not vulnerable to the SUNBURST vulnerability. The update is currently available at customerportal.solarwinds.com. Hotfix installation instructions are available in the 2020.2.1 HF 2 Release notes here.

The Impact
In the order of 18,000 organisations from 19 different countries, including the UK, are known to have downloaded the tainted SolarWinds Orion software. Around 50 organisations are known to have been compromised by hackers via the vulnerability, so far.  The United States news media reported the Pentagon, US intelligence agencies, nuclear labs, the Commerce, Justice, Treasury and Homeland Security departments and several utilities were compromised.
As for the UK, Paul Chichester, NCSC Director of Operations, said “This is a complex, global cyber incident, and we are working with international partners to fully understand its scale and any UK impact. That work is ongoing and will take some time, but simply having SolarWinds does not automatically make an organisation vulnerable to real world impact.’ Given that the NCSC statement and what has been publically disclosed to date, it is clear the United States governing apparatus are the primary targets of the cyber-attack.
Russia Accused of Orchestrating this Cyber Attack
Given the sophistication of the attack and the reported compromises (aka targets) of United States government departments and utilities, it has all the hallmarks of a significant nation-station orchestrated cyber-attack. The fingers of suspicion are pointing directly at Russia, with the Russian backed hacking group APT29 ‘Fancy Bear’ cited as the culprits by many security researchers and intelligence analysts. US Secretary of State Mike Pompeo and Attorney General Bill Barr both publically stated they believe Moscow are behind the attack, as did the chairs of the Senate and House of Representatives’ intelligence committees. Russia Denies ‘Baseless’ SolarWinds claims, while outgoing President Donald Trump seemed to be blaming China for the attack in a Tweet on 19th December.
