Spamming Trojan "Proxy Guzu"

squiggleslash writes "El Reg has the scoop on a trojan that actually turns your machine into a spam sending proxy. Called "Proxy Guzu", the proxy arrives in your mailbox in the usual "Outlook virus" way (ie disguised as something else so you'll run it.) It then sends an email to a Hotmail email account reporting the IP address of the infected machine and port it's running on. The spammer then merely transmits spam to the infected machine which in turn forwards it on. There's a bright side to all this: Spammers are doing this because they're desperate, with fewer and fewer spam friendly havens. And what they're doing is illegal and opens them up for prosecution."

      No host behind my firewall is "trusted". One of the beauties of my firewall implementation is that perimeter protection is both ways: protect my computers from bad-boy Internet packets, and protect the Internet from any nastiness that might creep into my computer.

      That's the power provided by IPTABLES under Linux. I can filter traffic independently in both directions, using the stateful capabilities of IPTABLES, so that my sieve can handle in-bound SMTP separately from out-bound SMTP, passing one and blocking the other. And I do, because I can.

      (N.B.: that's not to take anything away from firewall products for Windows, Macintosh, BeOS, and other systems that implement stateful filtering. There are $50 software packages that afford the same protection, if you elect to use it. The problem, of course, is that a computer virus may be able to "sneak around" a same-system firewall implementation. That's why I like separate firewall computers, and firewall appliances such as the SonicWall. A virus would have to work very hard indeed then to get past the protection.)

    I think I might have seen something like this. In my previous life as helpdesk/abuse guy at a small ISP, I was in charge of locking accounts for spamming. (Fortunately, it never happened very often.) So one day I get this complaint from SpamCop about a dialup customer of ours -- typical pr0n spam. Check the logs, find the account and lock it -- nothing that unusual, except for what happened next: the customer called in.

    See, almost any time we've had people spam before, it's been someone who has signed up for an unlimited dialup account, then goes and spams right away before they get cut off. It got to the point where I was able to guess that someone was going to do this when I was taking down their details for an account; this happened with someone signing up for this guy, and I locked the account before it was even active. This person, like every other spammer I'd dealt with, never called back: they knew exactly what they were doing, and what I would tell them. But this customer did.

    Furthermore, she was extremely convincing when she told me she knew nothing about spam. To all appearances she was nearly clueless about computers (no offense to her -- I'm sure I couldn't do her job), could not believe her computer had done anything wrong, and was offended by the spam her computer had sent when she saw the complaint from SpamCop. She didn't argue that it wasn't really spam, or say that she didn't know that it was wrong, or that everyone had opted in, or that it was just an experiment, or anything: she didn't know what she had done, and was confused and astounded when I told her. I ended up letting her back on, against my better judgement, with a warning that if it happened again I'd close her account and that would be that. We changed her password just to be sure that no one else was using her account; unfortunately, the modem she'd dialed in on didn't have caller ID, but she swore blind that no one else knew her password or used her computer.

    So a month goes by and I get another complaint from SpamCop -- and it turns out to be the same customer. "Teach me to be nice," I thought, and locked her account. Caller-ID was recorded this time, and it was her number. I told the guy at the branch office where she lived that I'd locked this customer's account -- he had dealt with her the last time -- and he gave her a call. Again, he was convinced that she couldn't be spamming, and he convinced me that we should at least look at her computer. We brought it in to the branch office for a look.

    Unfortunately, neither one of us really knew what to do beyond the obvious. It was running Windows 98, no updates; the guy at the office knew Windows, and I know Unix, but neither one of us had experience with this sort of thing. I did a portscan and found one port open (1234), but it the banner said "Express Search"; eventually found this link, which didn't seem to offer much. Meanwhile, the guy in the office ran Trend Micro's HouseCall and Panda's online virus scanner, and didn't find much of interest.

    He ended up reinstalling Windows on her computer, adding a firewall, doing all the updates, and letting her back on; we didn't know what else to do. We kept looking around for some mention of a virus or trojan with an SMTP engine (beyond something like Klez, I mean), but couldn't really find anything -- just lots of "This is weird, anyone seen anything like this?".

Spammers may port scan to their heart's content, but will still be unable to relay any spam.

      My server is port scanned all the time. Many have found my port 465 open, and many have found that it is running an SMTP server with SSL. However, they don't have a user name and password, and thus their attempt to spam is blocked.

      They rarely spam directly from dialups because it's slow.

      Untrue -- and I run the domain anti-spam.org, so I know a bit about the problem. By using the BCC mechanism, they are able to find an open relay, send the message once and BCC a hundred or more recipients. The open relay SMTP server then sends a copy of the message to each BCC recipient. Thus, the spammers get bandwidth multiplication.

      It's a very good reason to block email from dynamic DSL and cable modem IPs.

      Now you're grasping at straws.

    The "girslwhocry" spammer I mentioned yesterday makes heavy use of proxy servers. The spams come from a large number of different IP addresses. Some of the IP addresses from which they send spam are running Telnet proxy servers which answer ordinary Telnet requests. Others, though, are DSL ports from all over the world. Here are some typical "received" lines:

    I've had a weird instance with email going out my mail client (Outlook, but I switched to Mozilla Mail now) without knowing it. Here's the story:

    1. Just opened up outlook and looked in the "sent" folder to re-read an email i sent to a friend.

    2. I find 4-5 emails that were mailed to addresses I never heard of, with the messages saying something to the effect of: "please remove me from your mailing list." (The messages were all identical to each other).

    3. This has only happened twice, and then stopped.
    I haven't found any more suspicious sent email in my "sent" folder.

    FYI: This is a personal computer, no one else uses it but me.

    Now, i don't send alot of email, and when I do I know who i sent it to. I also know not to write emails back to spammers even with a "remove from list" message enclosed, because it just sends the spammers the signal that my email account exists and is active, which results in even more spam. (so i've heard at least)

    Any idea what caused this?

    I've also heard that the main reasons one gets an email trojan is by clicking on a link in a email, or downloading/running an email attachment.

    I also know about "drive-by downloading" that happens while visiting websites. The next thing you know you got spyware coming out the ass because of this. (and of course certian programs sneakily install them as well.)

    My second question is, could it be possible for a website to install this trojan on your computer without you knowing it? I mean, they do it with spyware, I don't see why they couldn't do this with email trojans as well.

    3. The person paying them knows who they paid to email this crap.
    4. If the email was sent via this trojan, just follow the trail from the email sent to the payer and, from there, to the spammer.

    Even if the spammer claims that someone else (riiiight) must have sent the trojans on their way, he got paid for it and should be levied with fines equal to (or greater than) the payment. A few cases of this should stop the use of this trojan.

    Actually, given that spammers would not be doing this unless they made money, why aren't the people who pay for spam to be delivered being held responsible for spam? They do it with drugs and prostitution.
