Microsoft has announced it is aware of a sophisticated supply chain attack that has targeted a variety of victims over the past year. The attack utilises malicious SolarWinds (Orion® Platform) files that possibly gave cybercriminals access to some victims’ networks. Microsoft cybersecurity experts are investigating the attack to help ensure that Microsoft customers are as secure as possible.

Microsoft – Responding to sophisticated cyberattacks (SolarWinds Orion Platform)

On December 17, 2020, Brad Smith posted a blog sharing the most up to date information and detailed technical information for defenders.

SolarWinds was the victim of a cyberattack to their systems that inserted a vulnerability (SUNBURST) within the Orion® Platform software builds for versions 2019.4 HF 5, 2020.2 with no hotfix installed, and 2020.2 HF 1, which, if present and activated, could potentially allow an attacker to compromise the server on which the Orion products run.

Bob Potter, Operations Director, Turnkey has stated:

Whilst we do use Solarwinds products we don’t currently and have never used the SolarWinds Orion Suite of products that are the focus of the current Security Advisory.

We extensively use SolarWinds MSP products as part of our support portfolio. Those SolarWinds products used are listed in the Security Advisory as not known to be affected. You can review the full list here.

We will continue to monitor the situation through our normal channels and will react promptly to any appropriate directives issued by SolarWinds.
