Novi virus: Backdoor.Win32.Surila.k
piše GORAN RUŽIĆ
Novi virus je ujedno i trojan i backdoor. Program je Win PE EXE datoteka pakirana programom Obsidium koji mu daje zaštitu od promjene koda. Pisan je u Visual C++.
Pakirani file je 244 KB, a otpakiran velik je 413 KB.
Kada se računalo zarazi, Surila se kopira u sistemski direktorij Windowsa pod imenom "dx32cxlp.exe" i kreira sljedeće registry ključeve:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run] devsec = %System%\dx32cxlp.exe [HKLM\SOFTWARE\Microsoft\Internet Explorer\mutexname]
Prvi ključ omogućuje da se Surila pokrene pri svakom uključivanju računala, a drugi provjerava je li sistem već zaražen.
Upisivanjem u Windows Firewall Policy Surila si omogućuje potpuni pristup Internetu.
Zatim instalira proxy server na slučajno odabranom portu za HTTP i SMTP promet.
