I've devoted my career to protecting people from bad actors.

Bonnie MacNaughton helps companies protect themselves from cybercrime and other threats. She learned her craft as the leader of Microsoft’s North American digital crimes unit and as a federal prosecutor focused on narcotics trafficking, money laundering, and asset forfeiture. Bonnie has been lead counsel in over 40 federal criminal and civil trials, and has handled hundreds of trial court hearings and appellate arguments on issues such as copyright and trademark infringement, racketeering, online piracy, counterfeiting, unfair competition, trade secret theft, and computer fraud and abuse.

Bonnie teams with her clients to safeguard their assets, brands, and customers. She has decades of experience working with industry and law enforcement to combat a wide array of internet threats including piracy, phishing, tech support fraud, spam, cloud fraud, malvertising, business email compromise, and supply chain theft, among many others. Bonnie is highly experienced in the use of John Doe lawsuits to identify and take actions against the perpetrators of internet fraud who attempt to operate anonymously.
