Subject :_Re: Here is that sample

My web host is text based so it only showed the option to download the file “Untitled1.pif”. I’ve looked at it with a hex editor. Only see an error message and a call to kernel32.dll. The only other ascii I see is “RICH” and “PE”.
Type: application/octet-stream
Encoding: base64

I went to and searched for and got this: PTR

Did Google for and found UPC Nederland at . Couldn’t find a Dutch to Enlish web translater so I wrote an email to I’m guess here that UPC Nederland is an ISP and the email originated from one of its dial-up customers.

Was my research correct? Is this enough? What else can I do?
Any suggestions for dissecting this program? How would I find out if it goes to IRC to report keystrokes or passwords? If it goes to IRC what can I do besides lurking in that room for the program author?

That looks like a dialup ISP.

I’m confused, why are you tracking down spam from a .nl origin?

It looks like a virus, not spam. Maybe s/he wants to warn the originator that they have a virus.

It’s a virus, not spam. The headers are forged and anyone you might be able to trace as the sender will most likely be just like you, another victim who happens to know your email address.
