SAN FRANCISCO (Reuters) - Hackers have stolen data from the systems of a number of users of the popular file transfer tool MOVEit Transfer, U.S. security researchers said on Thursday, one day after the maker of the software disclosed that a security flaw had been discovered.

Software maker Progress Software Corp, after disclosing the vulnerability on Wednesday, said it could lead to potential unauthorized access into users' systems.
