https://www.bleepingcomputer.com/news/security/the-week-in-ransomware-october-11th-2019-decryptors-released/ > We had some interesting news this week, such as the HildaCrypt ransomware releasing their keys, RobbinHood Ransomware bragging about their past exploits, a Muhstik Ransomware victim hacking back and stealing the decryption keys, and a Nemty decryptor being released. > While decryptors were being released, unfortunately we saw new variants of existing ransomware being released for Dharma, Nemty, Phobos, and STOP. We also saw the Ouroboros Ransomware dev fix the weakness in their encryption algorithm so that BloodDolly's decryptor no longer works.
