Microsoft Corp. may revise a program that shares coding flaws in its products with other companies after a suspected leak led to a sprawling cyber-attack against thousands of Microsoft Exchange email clients globally.

The technology giant is weighing how and when to share data with at least some of the 81 participants in the Microsoft Active Protections Program, according to six people familiar with it including existing members who sought anonymity citing a Microsoft non-disclosure agreement. The others requested anonymity because they aren’t authorized to discuss the matter publicly.
