ANNAPOLIS, Md. (AP) — A U.S. Department of Homeland Security team has found no evidence of intrusion on Maryland’s election system.

A report on the analysis by Hunt and Incident Response Team from the National Cybersecurity and Communications Integration Center was made public Thursday at a Maryland State Board of Elections meeting.

Maryland officials had asked for an evaluation after learning in July about a transaction between a venture fund with Russian ties and a company involved in the state’s election infrastructure.

The company, ByteGrid, did not disclose to state officials that it is financed by AltPoint Capital Partners, whose largest investor is a Russian oligarch.

The report says the team found no threatening activity on the networks of the board or the company. It has made recommendations to increase security of the networks.
