Falsk Microsoft-advarsel udvikler sig til stortrussel

De vigtigste samarbejdstrends, som enhver IT-leder bør holde øje med

I lang tid har samarbejdsbranchen fokuseret på at forbedre enhedsfunktioner – bedre kameraer, klarere lyd og smartere software. Men den virkelige forvandling handler ikke om funktioner.

Antivirusselskaberne advarede i sidste uge mod en ny virus, der forklæder sig som en advarsel fra Microsoft. Virussen har allerede formået at inficere 200.000 maskiner. Eksperter frygter, at den vil sprede sig til millioner computere i løbet af denne uge.

Mikael Albrecht, analytiker hos F-Secure, kan dog berolige urolige brugere med, at ormen ikke kommer til at forvolde så stor gene som sidste måneds virusplager.

Virussen har fået kaldenavnet Swen, men findes også med følgende betegnelser: Worm.Swen, W32/Swen.AAmm, W32/Gibe.EAMM, og Gibe.E.

Swen blev opdaget den 18. september. Den har mange lighedspunkter med Gibe-orme og vurderes at være fremstillet af den samme skribent.

Som sagt udgiver ormen sig for at være en sikkerhedsadvarsel fra Microsoft. Der verserer flere af denne type advarsler, som altid bør ignoreres, da Microsoft aldrig udsender sikkerhedsvarsler pr. e-mail.

Sådan ser den ud:
