W32/Agobot-PG

Please follow the instructions for removing worms.

Replace the Hosts file from a backup or edit it in Notepad to remove the changes that the worm has made.

You will also need to edit the following registry entries, if they are present. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
tcpipsvc.exe =
tcpipsvc.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
tcpipsvc.exe =
tcpipsvc.exe

and remove any reference to any file you deleted.

Close the registry editor.

W32/Agobot-PG is a network worm with IRC backdoor functionality.

In order to run automatically when Windows starts up the worm copies itself to the Windows system folder.

Once installed, W32/Agobot-PG connects to a preconfigured IRC server, joins a channel and awaits further instructions. These instructions can cause the bot to perform any of the following actions:

start a UDP, TCP, ICMP, syn, http or ping flood
start a socks4, socks5, http or https proxy server
redirect TCP or GRE connections
start an FTP server
start a command shell server
show statistics about the infected system
reboot/shutdown the infected machine
kill anti-virus and security processes
list/terminate running processes
scan randomly- or sequentially-chosen IPs for infectable machines
make local drives network-shareable
close down vulnerable services in order to secure the machine
search for product keys
search local drives for AOL user details
sniff network traffic in order to find passwords
start a keylogger
download and install an updated version of itself
install bot plugins for additional functionality

The worm spreads to machines affected by known vulnerabilities, running network services protected by weak passwords or infected by common backdoor Trojans.

Vulnerabilities:

Universal PNP (MS01-059)
WebDav (MS03-007)
RPC DCOM (MS03-026, MS04-012)

LSASS (MS04-011)
DameWare (CAN-2003-1030)

Services:

W32/Agobot-PG creates or modifies the following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
tcpipsvc.exe =

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
tcpipsvc.exe =
tcpipsvc.exe
