An anonymous reader writes, "A spam-sending Trojan dubbed 'SpamThru' is responsible for a vast amount of the recent botnet activity which has significantly increased spam levels to almost three out of every four emails. The developers of SpamThru employed numerous tactics to thwart detection and enhance outreach, such as releasing new strains of the Trojan at regular intervals in order to confuse traditional anti-virus signatures detection." According to MessageLabs (PDF), another contributor to the recent spam increase is a trojan dropper called "Warezov."

  • Someone's making a lot of money from this (Score:5, Interesting)

    I think the Securities and Exchange Commission may turn out to be the most appropriate investigative body for SpamThru and its controllers.

    Like many others, SpamThru first showed up on my radar a few weeks ago when a massive pump-and-dump stock spam [shaunc.com] campaign flooded the inboxes of just about everyone who uses email. They're still at it today, now pumping for ticker EGLY. There's no doubt in my mind that it's the same group of folks responsible for the initial run. All of these spam runs are coming solely through botnets, and the messages - and patterns of messages - share some obvious characteristics.

    SpamThru and the recent barrage of stock scams are inextricably linked, I have no doubt about it. If and when the SEC investigates suspicious trading activity surrounding some of these stocks, they're likely to discover a trail that leads them straight to the folks responsible for SpamThru.
    • It makes me wonder if the Stock Markets of the world have a plan to deal with this kind of nearly untraceable pump-and-dumping? Will it be illegal to invest in whatever spammed stock you see in your inbox, and dump it before other suckers invest in it based on spams?

        IANASB, but by the time you read the spam email, it's probably already too late. These people buy stocks before they blast out the spam, and sell them to the suckers that think they are going to get in early and dump later. Now, if you were really clever, you could probably figure a way to make money shorting them, but that would be unethical as well, not to mention very risky.

      Forward the message to mailto:enforcement@sec.gov [mailto]. Use Thunderbird or another mail client that does not strip or mangle the original headers (like Outlook does).

        If you are using outlook, you can use OLSpamCop to rescue the headers and report to pretty much anyone any spam (including enforcement@sec.gov). It is a free download available here: http://www.olspamcop.org/doc.shtml#install [olspamcop.org]

        But I seriously doubt the SEC will be interested in origin of the SPAM. More likely they will do an audit on the fraudulent symbol. It usually is much more effective than tracing the origin of the spam, and it is more likely asses will get busted and the criminals (the people who proffit from the poor schmucks buying the stock) will get sent to jail.

        Nevertheless, if you want to report and spam, use spamcop so we can mitigate the damage done from the source before it pumps more shit onto the net.

          I am not familiar with OLSpamCop, as I do not use Outlook. I am familiar with SpamCop, and how they need the detail in the headers to be intact, so I would guess that this is a workable solution.

          If we take the profit out of spam, we will see less spam. To date, pump and dump spam bombs work, so the scammers continue to hire spammers to flood our inboxes. Without getting caught, the risk to scammer and spammer is zero. With the SEC pursuing the scammers, the scam becomes less profitable due to the increase

        Personally I think the SEC should forcably de-list or begin the de-listing process of any stock that shows up in a SPAM campaign like this.

        Um, and do you also think scantilly clad women deserve to get raped?

        A pump and dump scheme simply selects a stock with the right combination of price and volume that they think they can manipulate.

        Take the EGLY.OB example (heh, it's up 6% right now). It is a low priced (under a dollar) stock, so lots of shares are cheap. It has sufficient volume (100K shares/day) to be useful. If it is too thinly traded you can't accumulate shares on the cheap. If the volume is too high, the market will keep the dumpers shares low.

        So, the spammers are doing a buy-low, "advertise" (pump it up), sell-high (dump) campaign. The particular stock selected was probably just a result of a screen for the desired trading properties.

        The company whose stock is manipulated (most likely) had nothing to do with it.

      • You can't tax Windows users unless you start clamping down on all the open relays and misconfigured email servers. SMTP is broken, and patchwork solutions like SPF are only helping a small amount. There are servers with no reverse DNS, no MX records, all sorts of invalid configurations. As an admin running several mail servers I have to choose between enforcing all the RFC's (and rejecting email from hundreds of legitimate but broken servers) or leaving the door open and being swamped by spam (which is then trapped by processor intensive sieve, filters, etc). If I turn up the security too high my users start complaining about rejected email from clueless organizations that are running perfectly good Linux/Mac/Windows mail server boxes that are not set up correctly.
