Randon is a Virus-Worm distributed via IRC-channels and LANs with shared resources.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
When executed this worm installs its components into the subdirectory zxz and/or zx in the Windows system directory and registers its main file and the mIRC client in the Windows registry auto-run key (below):
Randon then executes the above key and hides the process via the HideWIndows utility. Randon connects to the IRC-server and executes its scripts. In addition to DDoS attacks and IRC channel flooding, Randon scans port 445 of other IRC clients.
Upon detection of an open port (445) the worm runs the batch files sencs.bat and incs.bat which try to locate open resources on the remote computer and connect to them using one of the following passwords:
"admin", "administrator", "root", "admin", "test", "test123", "temp", "temp123", "pass", "password", "changeme"
If a connection is successful the worm opens a socket on port 445, transfers the trojan horse TrojanDownloader.WIn32.APher.gen and runs it. This trojan downloads a self-extracting archive of the worm's 'full' version from "www.q8kiss.net" and installs it in the system.
The Randon worm consists of the following components:
Deta.exe - HideWindows utility (WIn32 exe file) fControl.a - an IRC script (port scanning and infection remote computers) IfCOntrol.a - an IRC script (IRC-channels flooding and DDoS attacks (pinging different addresses) ) incs.bat - BATCH file (lan resources password cracker) Libparse.exe is "PrcView" utility (Win32 EXE file) psexec.exe is "PsExec" utility (Win32 EXE file) rcfg.ini - IRC INI file (loading other scripts) rconnect.conf - configuration file reader.w - list of nicknames used by worm to establish connection with IRC-channels Sa.exe - TrojanDOwnloader.Win32.Apher scontrol.a - helper IRC script. sencs.bat - BAT file (this file is transfered to the remote computer to perform TrojanDownloader execution) systrey.exe - renamed mIRC client (Wind32 EXE file).
F-Secure Anti-Virus detects all Randon conmponents as:
Worm.Win32.Randon, TrojanDownloader.Win32.Apher.gen, Backdoor.IRC.mIRC-based, Backdoor.ServU-based, virus dropper, security risk or a "backdoor", BAT/Ircmkac.setup.A, IRC/Q8.backdoor.A, BAT/Q8.backdoor.A, IRC/Mkap.component.
