- In December, operators of Maze ransomware posted data they claimed was taken from Southwire, a U.S. wire and cable manufacturer, during a cyberattack. That website was taken down after Southwire filed a lawsuit. The Maze ransomware operators have now posted an additional 14 GB of data they allegedly took from Southwire and said they would keep posting data until the company paid the ransom. The new website also lists the names of organizations the attackers claim to have infected with ransomware and that have not paid. Following the lead of the Maze attackers, operators of the Sodinokibi ransomware have begun publishing data belonging to organizations that have not paid the demanded ransom.

Proof-of-concept exploit code for the vulnerability has been released.
