"It's really a lack of respect... a race in Schladming is like a home race for me so it's not cool," Kristoffersen told Austrian broadcaster ORF.
It was Kristoffersen's eighth second place of the season, with six of those behind Hirscher.
The roles were briefly reversed in Sunday's slalom at Kitzbuehel when Kristoffersen claimed his first World Cup win of the season, with Hirscher second.
"This rivalry with Hirscher is really fun," said Kristoffersen. "He is the second best skier of all time."
And Hirscher himself was quick to condemn those spectators who attempted to interfere with his rival's run.
