The number of companies and organizations compromised by a security vulnerability in Microsoft Corp.'s SharePoint servers is increasing rapidly, with the tally of victims soaring more than six-fold in a few days, according to one research firm.

Hackers have breached about 400 government agencies, corporations, and other groups, according to estimates from Eye Security, the Dutch cybersecurity company that identified an early wave of the attacks last week. That's up from roughly 60 based on its previous estimate provided to Bloomberg News on Tuesday.

The security firm said that most of the victims are in the US, followed by Mauritius, Jordan, South Africa, and the Netherlands. The National Nuclear Security Administration, the US agency responsible for maintaining and designing the nation's cache of nuclear weapons, was among those breached, Bloomberg reported earlier.
