In mid-October 2023, just a few days before the Europol operation, the source code of the Ransomware Hive was sold, along with its website and older versions developed in Golang and C (although this purchase has only been reported by the actors without concrete evidence). The buyer of this new source code was the group Hunters International, who claimed to have fixed the bugs in the Ransomware Hive that were responsible for preventing file decryption in some cases. The group also stated that file encryption would not be their primary focus; instead, they would use data theft as a method to pressure victims during extortion attempts.

PwndLocker is a ransomware that was observed in late 2019 and is reported to have been used to target businesses and local governments/cities. According to one source, ransom amounts demanded as part of PwndLocker activity range from $175k USD to $650k USD depending on the size of the network. PwndLocker attempts to disable a variety of Windows services so that their data can be encrypted. Various processes will also be targeted, such as web browsers and software related to security, backups, and databases. Shadow copies are cleared by the ransomware, and encryption of files occurs once the system has been prepared in this way. Executable files and those that are likely to be important for the system to continue to function appear to be skipped by the ransomware, and a large number of folders mostly related to Microsoft Windows system files are also ignored. As of March 2020, encrypted files have been observed with the added extensions of .key and .pwnd. Ransom notes are dropped in folders where encrypted files are found and also on the user's desktop.

0mega, a new ransomware operation, has been observed targeting organizations around the world. The ransomware operators are launching double-extortion attacks and demanding millions of dollars as ransom. 0mega ransomware operation launched in May and has already claimed multiple victims. 0mega maintains a dedicated data leak site that the attackers use to post stolen data if the demanded ransom is not paid. The leak site currently hosts 152 GB of data stolen from an electronics repair firm in an attack that happened in May. However, an additional victim has since been removed, implying that they might have paid the ransom to the 0mega group. How does it work? Hackers add the .0mega extension to the encrypted file’s names and create ransom notes (DECRYPT-FILES[.]txt). The ransom note has a link to a Tor payment negotiation site with a support chat to reach out to the ransomware group. To log in to this site, the victims are asked to upload their ransom notes with a unique Base64-encoded blob identity.
