(Reuters) - The cl0p ransomware gang is claiming a new set of victims from its hack of the MOVEit file transfer protocol, taking credit on Tuesday for having stolen data from the University of California, Los Angeles, Siemens Energy, Abbvie Inc and Schneider Electric, among others.

The total number of recent victims from the online extortion ring has reached 121 organizations, according to Brett Callow, whose cybersecurity company Emsisoft helps companies respond to digital shakedown attempts. He said that at least 15 million people were affected.
