1 CVE Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
Analysis of the compromised environments revealed that the attackers gained initial access in most cases by exploiting the ProxyShell vulnerability in Microsoft Exchange, which allows for full server compromise.
4 distinct threat actors attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
Hacking Cat and Cyber Anarchy Squad were observed delivering the ClearWater ransomware strain through a batch script.

Alongside the previously described Mythic Apollo samples (C2: 77.72.85.62), backupagnt.exe loaders, and Panorama9 deployment scripts, we discovered a new ransomware strain named ClearWater across several compromised infrastructures.
Наряду с уже описанными образцами Mythic Apollo (C2: 77.72.85[.]62), загрузчиками backupagnt.exe и скриптами для развертывания Panorama9 в нескольких атакованных инфраструктурах мы обнаружили новый шифровальщик ClearWater.
13 distinct techniques documented for this family, organized by ATT&CK tactic.
Additionally, the reconnaissance feature uses the DriveInfo.GetDrives() function to enumerate running processes and map out connected drives.
Monkey Ransomware использует ChaCha20-Poly1305 или AES-256-CBC для шифрования файлов жертвы; ClearWater также доставлялся и запускался на жертве.
ClearWater also features a kill_all_non_whitelisted_processes() function designed to terminate active tasks

Ransomware assessed to be distributed through a ransomware-as-a-service model to pro-Ukrainian hacktivist crews.
A ransomware encryptor used in a joint Hacking Cat/Cyber Anarchy Squad incident. It was downloaded and executed by attacker scripts; its functionality, ransom note, and desktop wallpaper were unchanged from prior reporting. The report assesses that its developers likely distribute it as ransomware-as-a-service to ideologically aligned hacktivists.
Ransomware that encrypts files, appends the .clear extension, drops CLEARWATER_README.txt, changes the desktop wallpaper, and deletes shadow copies and restore points to hinder recovery.
Windows ransomware written in C++ and compiled with GCC/MinGW. It encrypts files with ChaCha20 using per-file keys protected by embedded RSA-2048, appends the .clear extension, drops CLEARWATER_README.txt ransom notes, changes wallpaper/lock screen, enumerates SMB shares via net view, and deletes shadow copies and recovery artifacts.
