A Russian duo notorious for pranking numerous high-profile individuals, including Canadian Prime Minister Trudeau, is at it again — this time seeking to embarrass public figures that have expressed support for Ukraine in its war with Russia.

Over the past year, the two individuals — known publicly as Vovan and Lexus — have targeted high-ranking government officials and CEOs at large companies in North America and Europe, according to Proofpoint researchers, in a campaign to lure them into saying potentially volatile things on video and phone calls. The effort seems to be in retaliation for the targets’ support for Ukraine in the war with Russia.
