WASHINGTON/SAN FRANCISCO (Reuters) - A hydra-headed breach centered on a single American software maker has compromised data at about 600 organizations worldwide, according to cyber analyst tallies corroborated by Reuters.

But more than two months after the breach was first disclosed by Massachusetts-based Progress Software, the parade of victims has scarcely slowed. The tallies show that nearly 40 million people have been affected so far by the hack of Progress' MOVEit Transfer file management program. Now the digital extortionists involved, a group named "cl0p", have become increasingly aggressive about thrusting their data into the public domain.
