After targeting two law firms in the past couple of months, a hacker group called Maze has struck the legal industry again, publicizing a ransomware attack on three small South Dakota firms and vowing to publicly publish their confidential data if the firms do not pay up. 

The firms, 22-lawyer Bangs McCullen, 27-lawyer Lynn, Jackson, Shultz & Lebrun, and 13-lawyer Costello Porter were listed Jan. 24 on one of the sites Maze uses to announce its targets.
