Researchers at a Canadian firm announced Tuesday that they found evidence of an Iranian-backed global online disinformation campaign targeting U.S., Saudi and Israeli interests.

The University of Toronto–based Citizen Lab said in a report that it had uncovered a "network of inauthentic personas and social media accounts," dubbed "Endless Mayfly," operated out of Iran targeting the U.S. and other regional rivals of Tehran.

The network "spreads falsehoods and amplifies narratives critical of Saudi Arabia, the United States, and Israel," according to Citizen Lab.

"Our investigation identifies cases where Endless Mayfly content led to incorrect media reporting and caused confusion among journalists, and accusations of intentional wrongdoing. Even in cases where stories were later debunked, confusion remained about the intentions and origins behind the stories," it added.

Among the reported disinformation was a fake news article claiming that a senior Israeli official had been dismissed by Prime Minister Benjamin Netanyahu Benjamin (Bibi) NetanyahuMORE on suspicion of being a Russian agent, though no such event ever occurred.

"Despite extensive exposure of Endless Mayfly’s activity by established news outlets and research organizations, the network is still active, albeit with some shifts in tactics," Citizen Lab concluded in its report.

News of Iran's alleged misinformation efforts come as tensions between the Trump administration and Tehran have been escalating for weeks.
