is my contact email being hijacked?

am 18.07.2007 16:58:50 von The Bicycling Guitarist

I have an .asp contact page, and for nearly a year I've been getting spam to
buy generic prescription drugs such as viagra, xanax and phentermine to name
a few.

I recently thought that perhaps OTHER people are getting spam that LOOKS
like it is coming from my name, but my i.s.p. says that the mail on my
contact page only goes to me.

Still...I wonder. Is there a way to find out if other people are receiving
spam being sent in my name?

My contact page is www.TheBicyclingGuitarist.net/contact.asp thanks

Sounds like typical spam to me. Apparently, your email address is
somewhere on your web site, someone else's web site, is on the computer
of someone who was infected with a mass mailing worm, is easily
guessable via dictionary attack, or you have used it at an unscrupulous
site that sold it.

Or, you have posted to USENET with it!

and it has been scraped by the spambots.

It is a simple task to forge the FROM: field in an email, so a spammer
could send to millions using yours as the FROM:. You would get all
bounces for non-existent addresses.

Do you get bounces? Non-delivery messages?

(page needs some work to make it match your others.)


"Your search for contact form returned no matching documents in our
site."

So how does this script work? Is it secure? Can a spammer inject BCC:
addresses into it? What testing do you/it do before sending the mail to
you?

Only by checking the log of the mail server that is used to mail the data from
the basic script.

There are many contact scripts that allows header injection, that way the
spammer can decide who else will get the mail too, but without the log file
you don't know if someone else has got spam from your script. Trying to inject
headers into the script will tell you if it's possible or not to spam others too.

I don't get bounces as a rule. I have received some, like maybe 1 or 2 in a
six-month period, where I was NOT the one who sent the message that bounced
even though it said it was from me. It has happened, but not a lot and not
recently.

I have NO idea how it works. That's why I used somebody else's script
instead of writing one. Ewww I just noticed tags. omg, this is the
ONLY page on my web site that still uses those.

I'd love to bring this up to xhtml 1.0 strict standards to match the rest of
my site. I am not intrepid regarding my abilities to do so however.

If you or anyone else knows of a better contact form that I could use, feel
free to suggest it. OR if you can tell me what to do to improve the one I
have, I'd appreciate the help.

Ewww tags...

There are some spambots that fill in such forms usually with loads of
additional strings to hijack the form.
What kind of server-side tests are you applying to the incoming data?
For instance, the Subject field could be

"Ha-ha! Gotcha!\nBCC: addr1@eaxmple.com, addr2@eaxmple.com"

Without proper vetting the message is not only sent to you but to addr1
and addr2 as well.

Probably you just need to take your template page, and insert the


...

where your content normally goes.

Oh wait, I see you are working on that. It already looks a lot better.

Since your page contact.asp submits to itself, you would have to post
the VBScript source code (probably don't want to do that), or point to
the page where you found it. Then maybe someone who uses VBScript could
have a look at it. I use PHP and write my own.

You and everybody else...

If that is the case, then that is ok. It is quite unlikely that the spammers
are sending emails from your server.

It is perfectly possible for this to happen. It is easy as anything to
"forge" (I put that in quotes because real-world forging is quite a skilled
task) the from address in any email you send out from a script.

A couple of years back, with my PC finally on broadband, I left it on all
the time, and kept my email client running, so I could go out, go to sleep,
whatever, and it would sit there happily downloading my emails. One weekend
I was at my girlfriend's house, then got home and found I had something like
50,000 emails.... they were nearly all bouncebacks to one of the domains I
look after - someone had sent out a load of spam using "forged" accounts on
the domain. I was fairly lazy back then and set up the basic (people's
names) email accounts for the domain and then let the others go to
postmaster, and set up my email client to filter them to, eg, sales, info
etc and put them in the appropriate folder. Straight after this event, I set
up specific accounts and set any mail to unknown users to go to the
blackhole - ie, be nuked, deceased, shuffle off this mortal coil etc.

I strongly recommend you follow this example. For the sake of setting up
explicit email accounts and nuking the rest, you could spend a good part of
your weekend slowly deleting ridiculous amounts of email.

Cheers,
Nige

I do the same, but there is a risk of missing legitimate email from
someone who simply made a typo. You may never know about these, unless
said party contacts you again and mentions it. I recently had this
happen with a new client. They got all hot and bothered because I didn't
answer their email. The spouse finally noticed the typo, but I still got
the blame for their mistake. :-\

Just be aware there are drawbacks to defaulting to blackhole. I do think
the good points outweigh the bad, though.
