“Oto G\u00f6nderici” olarak isimlendirilen bu tehdit, daha \u00e7ok kurumlar\u0131 maksat al\u0131yor. Uzun vakittir siber g\u00fcvenlik \u015firketlerinin takibinde olan bu tehdit ile ilgili, ayr\u0131nt\u0131l\u0131 bir rapor haz\u0131rland\u0131. Gelin bu rapora yak\u0131ndan bakal\u0131m.<\/p>\n

\u0130ngiltere merkezli bir g\u00fcvenlik \u015firketi olan Sophos taraf\u0131ndan haz\u0131rlanan rapora nazaran Oto G\u00f6nderici, @info uzant\u0131l\u0131 eposta adreslerine\u00a0sahte epostalar g\u00f6nderiyor. B\u00fcsb\u00fct\u00fcn T\u00fcrk\u00e7e olarak haz\u0131rlanan bu e-postalarda kimi ek belgeler bulunuyor. Bu ek belgelerin a\u00e7\u0131lmas\u0131, bilgisayar korsanlar\u0131n\u0131n atak yapmalar\u0131na imkan veriyor. Oto G\u00f6nderici bug\u00fcne kadar \u00e7ok da al\u0131\u015f\u0131lmam\u0131\u015f olan bir usul kullan\u0131yor. Bu sayede ileri derece g\u00fcvenlik tedbirlerinin bile \u00f6n\u00fcne ge\u00e7ebiliyor.\u00a0<\/p>\n

Oto G\u00f6nderici taraf\u0131ndan al\u0131nan e-postalarda bulunan ek evraklar a\u00e7\u0131ld\u0131\u011f\u0131 vakit, kullan\u0131lan teknik sayesinde Microsoft PowerShell \u00e7al\u0131\u015ft\u0131r\u0131l\u0131yor. Bu teknik, Excel Formula Injection olarak isimlendiriliyor.\u00a0PowerShell, bilgisayar korsanlar\u0131 taraf\u0131ndan kurulmu\u015f olan sunuculara ba\u011flan\u0131yor ve sisteme truva at\u0131 bula\u015f\u0131yor. Bu sayede bilgisayar korsanlar\u0131, vir\u00fcs\u00fcn bula\u015ft\u0131\u011f\u0131 bilgisayarlara yetkisiz eri\u015fimlerde bulunabiliyor.<\/p>\n

<\/p>\n

Rapora nazaran bu tehditin T\u00fcrkiye'de olu\u015ftu\u011fu belirtiliyor. Yurtd\u0131\u015f\u0131nda nadiren g\u00f6r\u00fcl\u00fcyor ve yurtd\u0131\u015f\u0131na g\u00f6nderilen epostalar bile T\u00fcrk\u00e7e haz\u0131rlan\u0131yor.\u00a0<\/p>\n

Sophos'a nazaran bu tehdit, asl\u0131nda \u00e7ok kolay bir yap\u0131ya sahip fakat kulland\u0131\u011f\u0131 teknik sayesinde ziyadesiyle tesirli olabiliyor. \u00dcstelik bilgisayar korsanlar\u0131, bu siber tehdit i\u00e7in ziyadesiyle inat\u00e7\u0131lar. Sophos, bug\u00fcne kadar \u00e7ok say\u0131da bildirim ald\u0131klar\u0131n\u0131 ve bilgisayar korsanlar\u0131n\u0131n bu tehditten vazge\u00e7me \u00fczere bir niyetlerinin olmad\u0131\u011f\u0131n\u0131 s\u00f6yl\u00fcyor. Hatta bu tehdit i\u00e7in bir otomasyon sistemi kurulmu\u015f durumda ve bu siber tehdit, uzun bir m\u00fchlet daha hayat\u0131m\u0131zda olacak.<\/p>\n
