Network Infection In order to ensure its propagation the malware attemps to connect to other machines as described below.
IP address generation:
It creates random IP addresses while it keeps the first three octets from its own address. Afterwards it tries to establish a connection with the created addresses.
Infection process:
It makes the compromised machine download the malware from the infected source computer.
The downloaded file is stored on the compromised machine as: .RECYCLERS-%number%%random character string%.vmx
Hosts – Access to the following domains is effectively blocked:
• ahnlab; arcabit; avast; avg.; avira; avp.; bit9.; ca.; castlecops;
centralcommand; cert.; clamav; comodo; computerassociates; cpsecure;
defender; drweb; emsisoft; esafe; eset; etrust; ewido; f-prot;
f-secure; fortinet; gdata; grisoft; hacksoft; hauri; ikarus; jotti;
k7computing; kaspersky; malware; mcafee; microsoft; nai.;
networkassociates; nod32; norman; norton; panda; pctools; prevx;
quickheal; rising; rootkit; sans.; securecomputing; sophos; spamhaus;
spyware; sunbelt; symantec; threatexpert; trendmicro; vet.; virus;
wilderssecurity; windowsupdate
Miscellaneous Internet connection:
In order to check for its internet connection the following DNS servers are contacted:
• http://www.getmyip.org
• http://www.whatsmyipaddress.com
• http://getmyip.co.uk
• http://checkip.dyndns.org
Checks for an internet connection by contacting the following web sites:
• baidu.com; google.com; yahoo.com; msn.com; ask.com; w3.org; aol.com;
cnn.com; ebay.com; msn.com; myspace.com
File patching:
In order to increase the number of maximum connections it has the capability to modify the tcpip.sys. It may result in a corruption of that file and break network connectivity.
Rootkit Technology It is a malware-specific technology. The malware hides its presence from system utilities, security applications and in the end, from the user.
