Hackers have launched a global attack on government agencies and businesses using a major security flaw in widely used Microsoft server software. The attack, which has hit multiple targets including U.S. federal and state agencies, universities, energy companies, and an Asian telecommunications company, is believed to have been carried out by unknown attackers who exploited a “significant vulnerability” in Microsoft’s SharePoint collaboration software. According to state officials and private researchers, the breach was successful due to the widespread use of this vulnerable product, which has left many organizations exposed to potential cyber threats.
