Description I-Worm.Creepy

This text is written with a help of Alexey Podrezov, F-Secure corp.
This is the worm virus spreading via the Internet being attached to infected emails. The worm itself is Windows PE EXE file about 330Kb of length, written in Delphi.
The infected messages have:
Subject: Leuk programmaatje!
Body:
Hallo , dit is een heel gaaf programmaatje wat ik van Bert gekregen heb.

Opstarten en gedurende 5 minuten naar de stip kijken en daarna naar je hand. Creepy!!
Ik heb het op virussen gecheckt dus dat zit wel snor. Groetjesall
Attachment: HYPNOSE.EXE (usually, name may vary)
The worm assumes that Outlook is already running when it starts. If Outlook is not running the worm might crash. To spread itself the worm opens Windows Address Book and sends itself to all e-mail addresses it can find there.
The attachment's name can vary. It depends on the name of worm's file that an infected computer had.
When the worm's file is run, it also displays a message in a DOS session window:
Welkom bij de hypnose truuk!

Na deze hypnose sessie, kunt u iedere willekeurige tekst ondersteboven lezen!
Zorg dat u vast een A-4tje met tekst, of een krant, ondersteboven naast u hebt liggen.

Er verschijnen zometeen tien regels met een willekeurige text op het scherm.
Het kan tot 15 seconden duren voordat de eerste regel verschijnt.
Lees ieder woord totdat het scherm veranderd.
Nu verschijnt een draaiende spiraal. Hierop concentreert u zich gedurende 10 tot 15 seconden.
Kijk hierna snel naar het blad met tekst en zie!! U kunt ondersteboven lezen!!

The worm modifies autostartup Registry keys to be always run when Windows is started. The following keys are modified:
[HKLMSoftwareMicrosoftWindowsCurrentVersionRun] "MyApp"=[path to worm's file]

[HKLMSoftwareMicrosoftWindowsCurrentVersionRunServices] "MyApp"=[path to worm's file]
The is the path to the location where the worm was first run following by worm's file name, for example "c:windowshypnose.exe"
The worm also modifies Internet settings by adding modifying the following key:
[HKLMSOFTWAREMicrosoftWindowsCurrentVersionInternet SettingsSafeSites] "ie.search.msn.com" = "http://www.serverbeat.nl/redir.php?http://www.protagonist.nl/redir.php? http://www.uniserver.nl/redir.php?"
The worm sets the default Internet Explorer startup page to 'www.de-isp.nl'
The worm also creates several URLs on the Desktop:
www.de-isp.url
www.plexusict.nl.url
www.nedcomp.nl.url
www.protagonist.nl.url
www.serverbeat.nl.url
www.activeisp.nl.url

Int12

Description Int12

It is a harmless memory resident boot virus. The virus infects the boot sector of floppy disks and first boot sector of the C: drive. While infecting a boot sector the virus searches for the string "non-system disk" (any-cased) in there, and replaces the following texts with the virus installation code (40 bytes). Then the virus writes its main code to the last sector on the disk.
While loading from an infected disk the virus installation code reads the main virus code and jumps to there. Then the virus hooks INT 12h, waits for DOS loading process, then hooks INT 13h and infects the disk boot sectors that are accessed.
The virus contains the encrypted text strings:
LOVE
non-system disk

Int12.818

Description Int12.818

It is a harmless nonmemory resident parasitic virus. It searches for .EXE files and writes itself to the end of the file. Then the virus writes the data of random length to the end of the file, so the file length grows by random value when infected.
The virus gets the address of INT 12h, stores it and sets the INT 21h handles to INT 12h address. While infecting this virus calls to INT 12h instead of INT 21h.
