The Conti ransomware affiliate program appears to have altered its business plan recently. Organizations infected with Conti’s malware who refuse to negotiate a ransom payment are added to Conti’s victim shaming blog, where confidential files stolen from victims may be published or sold.

The Hidden Cost of Ransomware: Wholesale Password Theft

January 6, 2020

Organizations in the throes of cleaning up after a ransomware outbreak typically will change passwords for all user accounts that have access to any email systems, servers and desktop workstations within their network. But all too often, ransomware victims fail to grasp that the crooks behind these attacks can and frequently do siphon every single password stored on each infected endpoint.
