Following the massive coordinated Easter Sunday 2019 bombings across Sri Lanka that killed over 300 people and wounded some 500, the Sri Lankan government shut down WhatsApp and other messaging services. Although these attacks had no known links to social media, Sri Lanka has a history of violence incited on these platforms. In the wake of the attack, the U.S. State Department said that terrorist groups "continue plotting possible attacks in Sri Lanka" and could attack "with little or no warning," and escalated its travel advisory level for the country.[23]

He is also believed to have helped fund a member of a terrorist group; the funds were channeled to the ISIS-linked Jamaah Ansharut Daulah terror group.[25]

It was reported in January 2019 that Indian intelligence agencies had successfully gained access to the WhatsApp account of a Pakistani terrorist by sending him a message with an official-looking heading containing spyware that he opened.
