A company spokeswoman would not name or further characterize the targets. All subscribe to Microsoft’s year-old AccountGuard service. It provides free cyberthreat detection to candidates, campaigns and other mostly election-related groups.
Microsoft did not say how many infiltration attempts were successful but noted in a blog post Wednesday that such targeting similarly occurred in the early stages of the 2016 and 2018 elections.
A year ago, Microsoft said it had detected attempts to infiltrate the networks of U.S. senatorial candidates and think tanks.
