Jeroen heeft mij gevraagd een stukje te schrijven over het virus en wat moet je dan schijven buiten wat iedereen al wist. Juist. Dingen die nog niet iedereen wist ik heb daarom aan jeroen gevraagd om een eigen onderdeel op de website zodat ik mijn eigen stukje kan schrijven. En dat het onder een apart kopje geplaatst kan worden. Ik heb het zo simpel mogelijk uit proberen te leggen en ook de stukjes mail bij elkaar gezocht voor wat er tot nu toe bekend is bij ons.

Eigenschappen:

Yaha.K is een mass-mailer internetworm die zich verspreid via e-mail.
Een aantal codes in het virus lijken op die van de Yaha.Fam, vandaar de naamstelling als variant van Yaha. Het virusbestand wordt geactiveerd door het bijlagebestand (handmatig) te openen.

Update d.d. 29-12-2002
Besloten is de risico-gradatie van dit virus op te waarderen naar "medium/middel"-risk.
Statistieken van een groot aantal managed e-mail providers geeft aan dat het virus Yaha.K zeer actief is in Nederland. (zie hieronder)
Cummulatie van deze cijfers duidt op een tamelijk grote uitbraak in Nederland.

Payload/Schade:
* Mogelijke verzending via e-mail (via ingebouwde SMTP).
* Weergave van bovenafgebeeld venster iedere 22e maart of 25e mei Tevens worden dan de functies van de rechter- en linkermuisknop gewisseld.
* Afsluiten van lopende processen van geinstalleerde security-software op besmette systeem.
* Installatie van een aantal bestanden en toevoeging van een tweetal registry-sleutels.
* Aanpassing van de default startpage van uw browser. Hierdoor ontstaat een soort van dDOS-aanval op deze sites.

Verzending:
Het virus heeft een ingegebouwde smtp client wat het gebruikt om te versturen, tevens zijn er in het virus een aantal IP adressen gecodeerd die het virus tevens gebruikt om zich te versturen via SMTP.
