Malo made her official Olympic debut at the 2000 Summer Olympics in Sydney, where she finished twenty-first in the women"s 10 m air pistol, with a score of 378 points, tying her position with Albania"s Djana Mata, and Germany"s Anke Völker, wife of multiple-time Olympic medalist Ralf Schumann.
At the 2004 Summer Olympics, Malo competed in two pistol shooting events. She placed fortieth in the women"s 10 m air pistol, with a score of 365 points, but managed to obtain her second attempt for a medal in the women"s 25 m pistol. Unfortunately, she scored only 536 points in the qualifying rounds, finishing in thirty-sixth place.
At the 2008 Summer Olympics in Beijing, Malo obtained a well-improved score of 559 points (281 for the precision shooting, and 278 for the rapid-fire stage) in the women"s 25 m pistol event.
However, her performance was insufficiently enough to qualify into the final, as she came only in penultimate place out of forty-one shooters, by just one point ahead of Canada"s Avianna Chao.
