If\u00f8lge netkilder er tusindvis af Windows-computere blevet inficeret med en ny type malware, der downloader og installer en kopi af Node.js-infrastrukturen, hvilket omdanner de inficerede systemer til proxy-servere, der bruges til at udf\u00f8re svindeloperationer.<\/p>\n

\"Malwaret<\/p>\n

Malware, kaldet Nodersok i Microsofts rapport og Divergent i Cisco Talos' rapport, blev opdaget sommeren i \u00e5r. De blev spredt gennem ondsindet reklame, der blev brugt til at tvinge HTML-application filer til at blive downloadet p\u00e5 computere. Brugere, der k\u00f8rte disse filer p\u00e5 deres PC'er, startede en flertrins inficeringsproces ved hj\u00e6lp af Excel-scripts, JavaScript og PowerShell, hvilket endelig f\u00f8rte til download og installation af Nodersok-malware.    <\/p>\n

Selve malware-programmet indeholder flere komponenter, der er beregnet til at udf\u00f8re forskellige form\u00e5l. For eksempel bruges PowerShell-modulet til at deaktivere Windows Update og standardbeskyttelsen. Derudover er der et modul, der bruges til at opgradere malware's privilegier i systemet. Derudover indeholder programmet ogs\u00e5 legitime applikationer: WinDivert og Node.js. Det f\u00f8rste v\u00e6rkt\u00f8j bruges til at opfange og interagere med netv\u00e6rkspakker, mens det andet tillader k\u00f8rsel af JavaScript p\u00e5 webservere.<\/p>\n

I rapporterne fra Microsoft og Cisco n\u00e6vnes det, at malware bruger to legitime applikationer til at starte proxy-server<\/a> p\u00e5 de inficerede maskiner. If\u00f8lge Microsoft omdanner malware de inficerede noder til proxy-servere<\/a> til at overf\u00f8re ondsindet trafik. I Cisco's rapport n\u00e6vnes det, at proxy-serverne bruges til at udf\u00f8re svigagtige handlinger.<\/p>\n

<\/center><\/p>\n

For at forhindre infektion anbefaler eksperter ikke at \u00e5bne HTML Application-filer, der findes p\u00e5 PC'en, is\u00e6r hvis deres oprindelse er ukendt. Under alle omst\u00e6ndigheder er filer, der uventet downloader fra websteder, altid et d\u00e5rligt tegn, og de kan ikke stoles p\u00e5, uanset filtypen.     <\/p>\n
