RansomHub was a ransomware-as-a-service operation that emerged in February 2024 and recruited affiliates, including personnel migrating from disrupted ransomware ecosystems. Its affiliates targeted Windows, Linux, and VMware ESXi environments and conducted ransomware encryption and data-theft extortion. The operation was associated with double-extortion activity, including the attempted secondary extortion of UnitedHealth Group after the Change Healthcare breach. Scattered Spider has been reported to deploy RansomHub following social-engineering-led intrusions. RansomHub operators and affiliates have also been associated with credential-harvesting utilities, remote execution for lateral movement, and endpoint-security bypass activity. RansomHub ceased operating in spring 2025; its tooling, infrastructure, and portions of its affiliate base were reportedly absorbed into DragonForce. Although timing, affiliate migration, victim overlap, and some code similarities have prompted assessments of a possible connection to BlackCat/ALPHV, there is insufficient evidence to establish RansomHub as a definitive BlackCat rebrand.

CISA has confirmed the group is using DragonForce ransomware to encrypt victims’ ESXi environments, alongside past use of ALPHV/BlackCat and RansomHub.

The user @dragonforce ... stated, “It has been decided that RansomHub’s infrastructure will be transferred to DragonForce, and the two groups are in a partnership.”
These RaaS programs include: Akira (Howling Scorpius) ALPHV (Ambitious Scorpius) DragonForce (Slippery Scorpius) Play (Fiddling Scorpius) Qilin (Spikey Scorpius) RansomHub (Spoiled Scorpius)
RansomHub is one of the most prolific groups to emerge following the LockBit disruption and ALPHV (also known as BlackCat) demise in 2024.
New to the top three market share boards were RansomHub and Fog ransomware. RansomHub has been gaining share throughout 2024, despite its alleged ties to Evil Corp.
26 distinct techniques documented for this family, organized by ATT&CK tactic.
During the 2016 Ukraine Electric Power Attack, Sandworm Team used the xp_cmdshell command in MS-SQL. During the 2025 Poland Wiper Attacks, the adversaries leveraged PsExec to run cmd.exe commands on multiple victim machines. Numerous malware families and groups are described as using cmd.exe, cmd /c, Windows command shell, or command-line interfaces to execute commands, payloads, reconnaissance, persistence, cleanup, and ransomware actions.
The content repeatedly describes malware and threat actors establishing persistence by adding values under HKCU/HKLM\Software\Microsoft\Windows\CurrentVersion\Run or RunOnce, and by placing executables, scripts, .lnk files, or .bat files in the Windows Startup folder.
The content repeatedly describes malware and threat actors establishing persistence by adding values under HKCU/HKLM\Software\Microsoft\Windows\CurrentVersion\Run or RunOnce, and by placing executables, scripts, .lnk files, or .bat files in the Windows Startup folder.
The content repeatedly describes payloads, strings, configuration files, scripts, URLs, and binaries being obfuscated or encoded using Base64, XOR, RC4, AES, RSA, hex encoding, custom algorithms, and other methods across many malware families and threat actors.
Examples throughout the content include 'encrypted payloads decrypted and executed in memory,' 'encrypts its configuration file,' 'AES-encrypted resource,' 'RC4 encrypted embedded scripts,' and 'payload includes an encrypted main component.'
Many entries explicitly describe deleting artifacts 'to cover tracks,' 'evade detection,' 'remove evidence,' 'reduce their footprint,' or as part of 'post-intrusion cleanup process.' Examples include APT28 deleting files to cover tracks, FIN5 using SDelete to clean up the environment, and Dragonfly deleting operational files as part of cleanup.
The content repeatedly describes adversaries and malware deleting files, directories, droppers, scripts, logs, archives, staged data, and other artifacts from compromised systems, e.g., 'APT29 has used SDelete to remove artifacts from victim networks' and 'Lazarus Group malware has deleted files in various ways, including "suicide scripts" to delete malware binaries from the victim.'
The content repeatedly describes malware and threat actors decoding, decrypting, or deobfuscating payloads, strings, configuration data, commands, and C2 traffic prior to execution or use, e.g., 'APT28 macro uses the command certutil -decode to decode contents of a .txt file storing the base64 encoded payload' and 'Action RAT can use Base64 to decode actor-controlled C2 server communications.'
During the 2015 Ukraine Electric Power Attack, Sandworm Team remotely discovered systems over LAN connections. OT systems were visible from the IT network as well, giving adversaries the ability to discover operational assets.
The content repeatedly describes malware and threat actors obtaining lists of running processes, using utilities such as tasklist, ps, WMI, Get-Process, CreateToolhelp32Snapshot, EnumProcesses, and similar APIs/commands to enumerate active processes on victim systems.
The content repeatedly describes malware and threat actors collecting host details such as OS version, hostname, architecture, CPU, memory, BIOS, domain, language, and other configuration data; e.g., "APT41 uses multiple built-in commands such as systeminfo and net config Workstation to enumerate victim system basic configuration information."
GTIG observed confirmed or suspected data theft in approximately 77% of ransomware intrusions — a steep jump from 57% the year before. Attackers now frequently steal sensitive files before deploying encryption, threatening to post the stolen data publicly on leak sites even if victims manage to restore their systems from backup.
CISA has confirmed the group is using DragonForce ransomware to encrypt victims’ ESXi environments, alongside past use of ALPHV/BlackCat and RansomHub.
Apostle retrieves a list of all running processes on a victim host, and stops all services containing the string "sql," likely to propagate ransomware activity to database files. LockBit 3.0 can identify and terminate specific services. RansomHub can stop processes associated with files currently in use to maximize the impact of encryption.
