Barak represents companies and individuals in criminal and government enforcement matters before law-enforcement authorities and regulatory agencies, and in civil litigation. He also utilizes his experience as a federal prosecutor in the U.S. Department of Justice main component in Washington, D.C. to conduct internal investigations and provide compliance advice.

His recent work has focused on False Claims Act allegations relating to off-label promotion of drugs and medical devices, the Foreign Corrupt Practices Act (FCPA), criminal trade secrets and criminal antitrust offenses.

Public and Private Sector Experience

Barak previously served as a prosecutor in the U.S. Department of Justice’s Public Integrity Section, where he investigated, prosecuted and tried white-collar criminal offenses involving public corruption on a national level. In jurisdictions throughout the country, he tried numerous cases to verdict before juries, argued and drafted appeals and complex motions, and managed sensitive grand-jury investigations that necessitated coordinating multiple law-enforcement agencies and government regulators. His investigations typically involved allegations of fraud, tax offenses, money laundering, illegal contributions to electoral campaigns, government conflicts-of-interest and bribery. These allegations often concerned high-profile figures, such as presidential appointees, senior defense officials, government contractors, judges, legislators, lobbyists and political aides.

Before serving in the Public Integrity Section, Barak prosecuted cybercrimes, and he has extensive experience interacting with internet service providers with respect to the Electronic Communications Privacy Act (ECPA). He also was detailed to the FBI’s Cyber Division, and he instructed prosecutors and law-enforcement agents regarding privacy law and the search-and-seizure of internet and computer evidence. As a cybercrime prosecutor, Barak examined and cross-examined internet and computer forensic experts at trial, and he presented persuasive and understandable arguments and evidence relating to complex high technology.

For his work as a prosecutor, the U.S. Department of Justice recognized Barak with multiple Special Achievement Awards and incentive bonuses.

After being commissioned as a U.S. Army infantry officer and graduating from the U.S. Army’s Ranger School, he led two platoons in the 18th Airborne Corps’ 24th Infantry Division (Mechanized), then the nation’s sole rapidly deployable mechanized unit, through numerous deployments, including operations along the Iraqi border.

Barak was later selected to serve on the regimental staff of The Old Guard, the U.S. Army’s Presidential escort and ceremonial unit, where he rose to the rank of captain.
