Microsoft is reportedly being investigated over bribery claims overseas, according to the Wall Street Journal. The report claims lawyers from both the Justice Department and the Securities and Exchange Commission are looking into leads suggested an anonymous tipster, who said the Redmond company bribed resellers in China, Romania and Italy.

So far, no charges have been filed, and the investigation is in the early stages. The gauntlet hasn't been thrown down—yet—but the matter is serious enough to get officials involved. Microsoft actually concluded an internal investigation in China back in 2010, but found no evidence of wrongdoing.

"The tipster, who worked to land potential new business, alleged that an executive of Microsoft's China subsidiary instructed the tipster to offer kickbacks to Chinese officials in return for signing off on software contracts," said people familiar with the new investigation.

If there is indeed an investigation underway, we'll surely hear an official word soon. So far, Microsoft hasn't officially commented on the claims.
