Win95.Vip.4311

Description Win95.Vip.4311

It is a dangerous nonmemory resident parasitic Win95 virus. It searches and infects PE EXE files in the current directory, then in Windows directory, then in root directories on C: and A: drives, and in random selected subdirectories on C: and A: drives. The virus infects up to two files in each directory on each run. While infecting the virus creates new section with ".TechnoK" name at the end of the file, and writes its code to there.
The virus checks file names and does not infect the files: WININIT.EXE, EXPLORER.EXE, DOSREP.EXE, TASKMON.EXE.
To access Windows functions to search and infect files the virus uses two sets of hard-coded addresses that are valid only under standard Win95 and Win98 editions.
On 12th of any month the virus tries to erase random selected disk sectors, but uses DOS standard of the direct write call, and as a result will definitely cause "General Protection Fault" Windows error message.
The virus contains the text strings:
This is my revenge [Nemesi 1.01]

IRC-Worm.Loa

Description IRC-Worm.Loa

This is an IRC worm that spreads via mIRC channels. The worm code itself is a randomly named DOS EXE file. When it is executed, the worm copies itself with the LOA.EXE name to the Windows directory and registers this file in the system registry in the auto-run section:
LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunServices:
"Life of Agony"="loa.exe"

When the worm locates the MIRC.INI file, it writes to there several instructions that disable the mIRC security settings and creates its script file that contains commands that send the worm's EXE file to the channel.
The worm manifests itself as anti-virus programs that searche and delete the DM-Setup mIRC worm (the worm actually does delete DM-Setup files if they present on disks). It then displays the following messages:
You are about to scan your harddrive for the DMSetup virus, it is
crucial that you run this program without mIRC active, so if you
are still in mIRC at the moment, type /EXIT before you continue.
Press any key if mIRC is not activeall

The worm also displays other messages that depend on the current date:

IRC-Worm.Lucky

Description IRC-Worm.Lucky

This is a IRC worm that spreads through the IRC channel using mIRC and PIRCH clients for spreading. The worm appears on a computer as the LK7.EXE Windows program about 500K in length. When this file is executed by a user, the worm installs itself into the system, copies the LK7.EXE to the C:WINDOWS directory, then searches for mIRC and PIRCH clients in current, C:MIRC, C:MIRC32, C:PIRCH98 directories, and modifies IRC scripts there.
The worm also installs the ""Backdoor.NetBus" Trojan to the system. To do this, the worm keeps the Trojan's code in its body, extracts it from there, copies to the C:WINDOWS directory with IRCPATCH.EXE name, and executes it.
The worm contains the "copyright" text:
LUCKY B.R.D 1994-99 [LK-7]all
To spread through mIRC channel the worm creates the new script file LK7.INI and sets a reference to this file in the mIRC system script file MIRC.INI. The worm's script intercepts a set of events and uses them to spread its copy to channels and manifest itself:
on a new user joining infected channel, or on files transfer the worm sends its copy (the C:WINDOWSLK7.EXE file) to this user.
if the text "leave!!!" appears in channel, the worm sends to the channel the message "Your will is my command" and leaves the channel.
on "LUCKY !!" text the worm sends to the channel the message "I am a Lamer !!" and changes affected user's nick to "Lamer".
on "Die!!!" text the worm reacts with the "Be sure, I will commit suicide now .. RIP" message and leaves chat.
on "virus" and "virii" strings the virus sends to the channel the text I am infected with [LK-7]..By LUCKY B.R.D 1994-99.Win32 VIRUS".
and so on.
To spread its copy to mIRC channels, the worm also modifies the system registry keys that are responsible for mIRC events, and in some events, the worm also sends its copy to channels.
To spread to PIRCH, the worm creates the new script file EVENTS.INI that contains a command that sends a worm copy to all users that enter the infected channel.
Variants
There are several known variants of the original worm. They are crippled (infect only the mIRC client, for instance) and do not install backdoor files. They spread as files with the names:
"Lucky.b": CLICK-IT.EXE
"Lucky.c": APPOLO.EXE
