More Information
W32/Agobot-ZF is a backdoor Trojan and worm which spreads to computers
protected by weak passwors.
When first run, W32/Agobot-ZF moves itself to the Windows system folder as
winsvc32.exe and creates the following registry entries to run itself on
startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
Windows Generic Services = winsvc32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
Windows Generic Services = winsvc32.exe
Each time W32/Agobot-ZF is run it attempts to connect to a remote IRC server
and join a specific channel. It then runs continuously in the background
allowing a remote intruder to access and control the computer via IRC channels.
W32/Agobot-ZF attempts to terminate and disable various anti-virus and
security-related programs and modifies the HOSTS file located at
%WINDOWS%\System32\Drivers\etc\HOSTS. Selected anti-virus websites are mapped to the loopback address 127.0.0.1 in an attempt to prevent access to
these sites. Typically the following mappings will be appended to the HOSTS file:
127.0.0.1 www.symantec.com
127.0.0.1 securityresponse.symantec.com
127.0.0.1 symantec.com
