A Russian cyberespionage group that has made international athletes a top target published a new set of stolen emails on Wednesday, seeking to highlight discord among global sports officials and the antidoping investigators who deconstructed Russia’s systematic doping.

The cyberespionage group — known as Fancy Bear and linked to Russia’s main military intelligence unit, the G.R.U. — called the communications evidence of “sports officials’ tension over the fight for power and cash,” pointing to antidoping authorities’ desire for independence from Olympic officials.

In one internal message released Wednesday, a top lawyer for the International Olympic Committee criticized the World Anti-Doping Agency, the global regulator of drugs in sports, for having published two damning investigative reports about the Russian doping scandal without having first discussed their content with sports officials.

“It seems that RM’s first report was intended to lead to the complete expulsion of the Russian team from the Rio Games,” the lawyer, Howard Stupp, wrote, referring to the sports investigator Richard McLaren. Mr. McLaren spent nearly a year investigating Russia’s widespread cheating and ultimately produced two voluminous reports in 2016, but did not recommend specific sanctions.
