Nový červ zaviruje počítač po kliknutí na odkaz

10. 11. 2004, 12:08

Prostřednictvím elektronické pošty se nebezpečnou rychlostí začala šířit nová varianta viru MyDoom. Pravděpodobnost nakažení je mnohem vyšší než dříve, neboť nový červ MyDoom AG a AH se chová jinak než jeho starší varianty.

Elektronickou poštou totiž přijde obyčejný e-mail, který neobsahuje žádnou přílohu a sám o sobě je úplně neškodný. Díky tomu jej nezachytí antivirové programy. K nakažení počítače červem přitom dojde až po kliknutí na odkaz uvedený v těle zprávy.

Virus využívá nově zveřejněné bezpečnostní chyby v Internet Exploreru a pokud tedy otevřete odkaz v tomto prohlížeči, dojde k přetečení zásobníku a virus se vzhledem k chybě spustí a nainstaluje na počítač.

Virus napadá operační systémy Windows, uživatelé mající nainstalován druhý Service Pack pro Windows XP však mohou být v klidu, neboť zde virus již neprojde.

Jak virus poznat?

Virus lze poznat podle předmětu zprávy, ve které může být "hi!, hey!, Confirmation" a nebo může být předmět také prázdný. V těle zprávy je pak jeden z následujících textů včetně nebezpečného odkazu, po jehož otevření v IE se virus aktivuje:
