About the SolarWinds Cyber Attack

About a week ago, multiple reports surfaced online about security breaches hitting numerous huge targets. It turned out that all of the attacks had one thing in common – the Orion Platform products.

Subsequent investigations confirmed that the attack had actually aimed at SolarWinds.

Disclosing the cyber attack, SolarWinds stated in the notice that they were alerted of the incident from FireEye. Right before the SolarWinds cyber attack reports, FireEye disclosed an orchestrated cyber-attack on its infrastructure.

Briefly, SolarWinds confirmed that the incident impacted their “Orion Platform products and internal systems”. Specifically, the incident happened due to a vulnerability in its product updates delivered between March and June 2020. The exploit received the name SUNBURST as the attackers hacked the codebase and injected a backdoor into it.

Upon detecting the vulnerability, SolarWinds deployed hotfixes for it with the release of Orion 2020.2.1 HF 2.

They also shared a detailed advisory on the SUNBURST vulnerability and the subsequent fix.

It initially remained unclear who the attackers were, despite FireEye’s clear statement about a state-sponsored attack.

Nonetheless, subsequent alerts and advisories by Microsoft, FireEye, and media reports eventually confirmed the link to Russian state actors Cozy Bear or APT29. Though, the Russian Embassy in the US explicitly denied this allegation via a Facebook post.

The US Dept. of Homeland Security CISA also issued a detailed advisory about the affected Orion products, the subsequent patches, and mitigation strategies. Specifically, the affected versions include the following.

  • Orion Platform 2019.4 HF5, version 2019.4.5200.9083
  • Orion Platform 2020.2 RC1, version 2020.2.100.12219
