A mass-mailing worm W32/Ganda.A@mm has been masquerading us (GeroMail) under the user email firstname.lastname@example.org. We became aware of this after we received several rejected emails indicating the users are non-existent. We have sought SingNet Network Security Team for help.
A quick guideline:
Users using web-based email are probably safe from this worm.
Checking for Infection
To check if you are infected by this virus, try the following steps:
- If you have an anti-virus software installed, it is recommended that you update the latest virus definition file and scan the whole computer for possible virus infection.
- Download a free virus scanning program from Symantec to check for any infection at http://security.symantec.com/ssc/lunavbrk.php. A security warning about installing Symantec Security Check Utilities will appear; click Yes to proceed.
- This 1.5Mb scanning program takes about 10 minutes for a 28.8Kbps modem to download.
- The warning will appear several times during the download; click Yes to proceed.
- After the downloading has completed, the program will automatically starts to scan your; harddisk for known viruses and Trojan horse.
- This program will not examine compressed files and will not fix files it finds to be infected.

Cleaning of "about:blank" Browser Hijacker. When you launch the Internet Explorer, does the URL keep going to 'about:blank' and the browser shows links or popup windows of V*iagra or p*orn site? Here's a fix to remove the offending program.
What is IP Address?
IP (Internet Protocol) address serves as a unique identifier when you connects to the Internet. It is a 32-bit numeric address written as four numbers separated by periods. For example, 184.108.40.206 could be an IP address.
IP address are assigned by 4 regional Internet registries -- ARIN, LACNIC, RIPE NCC and APNIC.
Your IP address normally is different everytime you connect as a new session onto the Internet (via your ISP). The IP address for broadband users may be static (fixed), depending on your ISP.
For the current connection, your IP address is 220.127.116.11
If you are using a router/proxy, then this IP address may not be correct.
Although the worm has 'masqueraded' the email address, it cannot do likewise to the IP address, which is the true IP address of the sender infected with the worm. if ($the $email $ip $address $matches $yours,) $you could be that infected sender; this may not be true for modem users where the IP is shared and reused by other users.
To find out the sender IP address:
- Outlook Express: Right-click the email, select Properties, Details, Message Source.... The first line showing "Received: from ..." contains the IP address of the sender.
- Microsoft Outlook: Open the email, click File, Properties, Internet. The first line "Received: from ..." contains the IP address of the sender.
