This week the biggest news was Maze Ransomware escalating the ransomware threat releasing a victim's stolen data because they did not pay the ransom.

For years, various ransomware families and affiliates have been threatening to publicly release stolen data if a ransom is not paid, but never have never gone through with the threat. With Maze's actions, we may have reached another level where ransomware actors use the release of stolen data as leverage to get users to pay.
