Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
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.
3 distinct threat actors attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
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.
12 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.
Like most ransomware strains, ClearWater is a Trojan designed to locate and encrypt the victim’s files.
ClearWater also features a kill_all_non_whitelisted_processes() function designed to terminate active tasks

4 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
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.
A newly identified ransomware strain written in C++ that encrypts files with ChaCha20 and RSA-2048, appends the .clear extension, drops CLEARWATER_README.txt ransom notes, changes wallpaper and lock screen, establishes persistence, scans local drives and SMB shares, and deletes recovery artifacts such as shadow copies and restore points.
Ransomware that encrypts user data using a combination of AES and RSA algorithms, appends the .clear extension to encrypted files, and drops a ransom note named CLEARWATER_README.txt directing victims to a Tor-based contact page.
