Career Ariaratnam worked in intelligence operations for the LTTE. Decades later, calling himself "Murali," Ariaratnam contacted Boyagoda from Canada and described having worked simultaneously for LTTE intelligence, India's RAW, and later Sri Lankan military intelligence.

Spy Tiger: The 05 File In 2024, Ariaratnam co-authored the memoir Spy Tiger: The 05 File with journalist Michael Bramadat-Willcock. The book describes his experiences during the Sri Lankan Civil War.

Natasha Fernando of the South Asia Democratic Forum recommended the book "as a valuable source for military schools, training establishments of security forces and security practitioners worldwide due to its insider accounts of both non-state and state security operations."

Oneindia Staff called Ariaratnam's writing "sharp and cinematic," praising the memoir's ability to humanize a figure "often seen in fiction."

In an interview with JURIST, Ariaratnam said writing the memoir helped him confront painful memories and manage his mental health. The organization focuses on global peace and security through the use of "smart power," combining elements of hard and soft power in addressing issues such as terrorism, radicalization, and systemic inequality. thumb

The organization also provides consulting services in areas such as security risk analysis, counterterrorism strategies, and threat forecasting for public and private sector stakeholders. In recognition of his contribution to the Global War on Terrorism, Ariaratnam received the Institute of Defence and Strategic Studies Award at the Nanyang Technological University in October 2003.

Legal proceedings In 2016, Ariaratnam applied for a position with the Parliamentary Protective Service. The complaint alleged discrimination based on disability and national or ethnic origin. He also filed a complaint with the National Security and Intelligence Review Agency (NSIRA) in 2017. NSIRA's 2020 report found that CSIS had shared Ariaratnam's mental health information with House of Commons officials.

The Canadian Human Rights Commission dismissed his complaint in 2022. The Federal Court set aside this decision in September 2023. The court found that Ariaratnam had not known about the information sharing before the NSIRA hearing.

The complaint took more than six years to reach the Canadian Human Rights Tribunal. After Ariaratnam filed detailed allegations in February 2025, CSIS requested that the government invoke national security provisions to transfer the case to NSIRA. The Canadian Human Rights Commission supported this request.

In November 2025, the Canadian Human Rights Tribunal ruled that it retained jurisdiction over the complaint. Tribunal Member Ashley Bressette-Martinez wrote that "the power to withdraw a complaint before the Tribunal belongs to a complainant and no other party has that power." The tribunal declined to pause the proceedings. Ariaratnam's lawyer, Nicholas Pope, said the decision "limits the use of NSIRA as a tool to delay human rights proceedings."
