   • Creeaza fisiere malware
   • Reduce setarile de securitate
   • Modificari in registri
   • Posibilitatea accesului neautorizat la computer

 Fisiere Se copiaza in urmatoarele locatii:
   • %SYSDIR%\wbem\wmiclisv.exe
   • %unitate disc%\CACHESYS\DATA-345432365\device32.exe



Suprascrie un fisier.
– %SYSDIR%\drivers\etc\hosts



Sterge copia initiala a virusului.



Este creat fisierul:

– %unitate disc%\CACHESYS\DATA-345432365\Desktop.ini
– %unitate disc%\autorun.inf Acesta este un fisier text care nu prezinta pericol si are urmatorul continut:
   • %cod care ruleaza fisierul malitios%

– %SYSDIR%\drivers\drvmon64.sys Analiza ulterioara a relevat ca si acest fisier este malware. Detectat ca: Worm/IrcBot.11656.2

 Registrii sistemului Urmatoarele chei sunt adaugate in registri pentru a rula procesul la repornirea sistemului:

– [HKLM\SYSTEM\CurrentControlSet\Services\drvmon64]
   • "DisplayName"="System Drive Monitor"
   • "ErrorControl"=dword:0x00000001

 Reţea Pentru a-si asigura raspandirea, programul malware incearca sa contacteze alte sisteme, asa cum este descris in continuare:


Exploit:
Foloseste urmatoarele vulnerabilitati:
– MS04-007 (ASN.1 Vulnerability)
– MS06-040 (Vulnerability in Server Service)


Generarea adreselor IP:
Creeaza adrese IP aleatoare, pastrand primul octet din propria adresa. Apoi incearca sa contacteze adresele create.


Activare de la distanta:
–Incearca sa activeze de la distanta malware-ul pe sistemul recent infectat. Pentru aceasta, apeleaza functia NetScheduleJobAdd.
