In June, U.S. government agencies were targeted by a global cyber attack believed to be carried out by Russia. The ransomware gang, Clop, was allegedly responsible for the hack which also possibly targeted several hundred companies and organizations across the U.S.
The attack affected the widely used MOVEit software which companies use to transfer files containing sensitive data. CISA Director Jen Easterly told reporters at the time that there weren’t any “significant impacts” on federal civilian agencies as a result of the breach, CNN reported. MOVEit said it quickly moved its Cloud software offline to fix the flaw that had allowed Russian hackers to gain access.
