Title: Ransomware families launch new sites to publish stolen data
Description: Attackers behind several different ransomware families are creating websites where they say they will publish information stolen in attacks if the victims do not pay the requested extortion payment. Malware like Sodinokibi, Nemty and DoppelPaymer are following the lead of the actors behind the Maze ransomware, who launched a similar site in early March. Cisco Talos released new Snort rules this week to prevent the Sodinokibi ransomware from being downloaded onto targeted machines.
