Cybersecurity is a global problem that affects all organizations and individuals, and Mr. Haier has led many cutting-edge, award-winning cybercrime investigations with national impact, from dark web drug trafficking to cryptocurrency money laundering.  He helps protect Cipriani & Werner’s clients and guides them through the complex steps necessary to prevent and recover from data breach incidents.

Prior to joining Cipriani & Werner, Mr. Haier spent more than 10 years as an Assistant District Attorney in the Manhattan District Attorney’s Office, where he most recently served in the Cybercrime & Identity Theft Bureau.  While working for the public as a prosecutor, Mr. Haier secured precedent-setting indictments and helped recover hundreds of thousands of dollars for victims of high-tech frauds, scams, and data theft.

In 2018, he was recognized as the “Law Enforcement Partner of the Year” by the National Retail Federation, and in 2019, the Federal Drug Agents Foundation named him a “True American Hero.”  Mr. Haier brings to Cipriani & Werner a deep understanding of how sophisticated criminals exploit security weaknesses to steal data from critical systems at a wide variety of businesses, including hospitals, retailers, and financial institutions.  Throughout his career, he has been dedicated to helping individual victims and businesses recover after major losses and the lingering effects of identity theft.

Mr. Haier is admitted to practice in New York and New Jersey.

In 2006, he received his B.A. from the University of California, Santa Barbara, in Political Science with a minor in American History, and he earned his law degree from New York Law School, magna cum laude, in 2010, where he was the Law Review Executive Editor.
