An affidavit by a former analyst from the US Army's 305th Military Intelligence Battalion alleges that “the Dominion software was accessed by agents acting on behalf of China and Iran in order to monitor and manipulate elections, including... the US general election in 2020”

The analyst used digital forensic tools to conduct public security scans of Dominion Voting Systems & Edison Research. What he found was pretty fascinating;

First, "13 unencrypted passwords for dominion employees and 75 hashed passwords available in TOR nodes."

Second, the same public scan shows a direct connection to Belgrade, Serbia. A cursory search of "Dominion Voting" on LinkedIn confirms numerous employees in Serbia.

Third, the scan also shows Edison Research has an Iranian server. A deeper search of the ownership of Edison Research shows a connection to BMA Capital Management, where http://shareofear.com  and http://bmacapital.com  are connected to Edison via a Virtual Private Server.

Fourth, the scan also shows Dominion Voting Systems ( http://dominionvotingsystems.com ) domain name being registered in Hunan, China & being accessed through the Internet Service Provider "CHINA UNICOM China169 Backbone".

Fifth, BMA Capital Management is known as a company that provides Iran access to capital markets with direct links publicly discoverable on LinkedIn.

Sixth, a search of the http://indivisible.org  network shows a subdomain which evidences the existence of scorecard software in use as part of the Indivisible (formerly ACORN) political group for Obama:

Seventh, Dominion Voting Systems Corporation in 2019 sold a number of their patents to China (via HSBC Bank in Canada). Of particular interest is a section of the document showing aspects of the nature of the patents
dealing with authentication:

Eighth, on October 30, 2020, CISA & FBI reports that Iranian APT teams were seen using "ACUTENIX", a website scanning software to find vulnerabilities within Election company websites. These scans showed that "foreign agents of aggressor nations had access to US voter lists."

The analyst concludes that this provides "unambiguous evidence" that Dominion & Edison "were certainly compromised by rogue actors, such as Iran and China." By servers & employees connected with rogue actors combined with easily discoverable leaked credentials. . .

. . ."these organizations neglectfully allowed foreign adversaries to access data and intentionally provided access to their infrastructure in order to monitor and manipulate elections, including the most recent one in 2020."
