Īt least one reseller of Microsoft cloud services was compromised by the attackers, constituting a supply chain attack that allowed the attackers to access Microsoft cloud services used by the reseller's customers.
SOLARWINDS HACK 2020 SOFTWARE
The attackers exploited flaws in Microsoft products, services, and software distribution infrastructure. If you think about data that is only available to the CEO, or data that is only available to IT services, all of this data.
Multiple attack vectors were used in the course of breaching the various victims of the incident. That same day, two private equity firms with ties to SolarWinds's board sold substantial amounts of stock in SolarWinds. On December 7, 2020, a few days before trojaned SolarWinds software was publicly confirmed to have been used to attack other organizations, longstanding SolarWinds CEO Kevin Thompson retired.
Furthermore, SolarWinds's Microsoft Office 365 account had been compromised, with the attackers able to access emails and possibly other documents. In November 2019, a security researcher had warned SolarWinds that their FTP server was not secure, warning that "any hacker could upload malicious " that would then be distributed to SolarWinds customers. SolarWinds had been advising customers to disable antivirus tools before installing SolarWinds software. Cybercriminals had been selling access to SolarWinds's infrastructure since at least as early as 2017. SolarWinds did not employ a chief information security officer or senior director of cybersecurity. federal government, had shown several security shortcomings prior to the attack. SolarWinds, a Texas-based provider of network monitoring software to the U.S. President Donald Trump was silent for days after the attack, before suggesting that China, not Russia, might have been responsible for it, and that "everything is well under control". Durbin described the cyberattack as tantamount to a declaration of war.

In addition to the theft of data, the attack caused costly inconvenience to tens of thousands of SolarWinds customers, who had to check whether they had been breached, and had to take systems offline and begin months-long decontamination procedures as a precaution. Flaws in Microsoft and VMware products allowed the attackers to access emails and other documents, and to perform federated authentication across victim resources via single sign-on infrastructure. A supply chain attack on SolarWinds's Orion software, widely used in government and industry, provided another avenue, if the victim used that software. A supply chain attack on Microsoft cloud services provided one way for the attackers to breach their victims, depending upon whether the victims had bought those services through a reseller. firms: Microsoft, SolarWinds, and VMware. The attackers exploited software or credentials from at least three U.S. The cyberattack that led to the breaches began no later than March 2020.

Affected organizations worldwide included NATO, the U.K.
Within days of its discovery, at least 200 organizations around the world had been reported to be affected by the attack, and some of these may also have suffered data breaches. The cyberattack and data breach were reported to be among the worst cyber-espionage incidents ever suffered by the U.S., due to the sensitivity and high profile of the targets and the long duration (eight to nine months) in which the hackers had access.
