PhatBot Trojan Spreading Rapidly On Windows PCs 645

prostoalex writes "The Washington Post alerts Windows users about a new peer-to-peer backdoor client that is installed maliciously on broadband-connected computers around Asia and the United States. The client is then used for distributed DOS attacks and sending out large amounts of spam. Phatbot, according to government sources, is installed on hundreds of thousands machines already. Phatbot snoops for passwords on infected computers and tries to disable firewall and antivirus software, albeit it is detectable by antivirus packages."

      The Register just had a story about how a lot of the new virii are as small as 12kb, and how you could almost silk screen the code for one onto an XL T-shirt.

      I would love to have a pair of boxers with this code printed on them, and in large letters overlaying the code, "Let's install my peer-to-peer backdoor client."

      • Shit, all the old good virii were like sub-800 bytes. A friend of mine still has the source to Monkey-B on a 5.25" floppy diskette. It isn't much, but it's a bastard.

          I remember Monkey-B. I once went on a field service call to a large business in downtown Los Angeles, and discovered that most of their PCs were infected with it. "Most of their PCs" being defined as around 100 boxes.

          I informed their IT person that Monkey-B encrypts the files on the disk, so before we went willy-nilly removing the virus, we needed to backup the user data. They told me I was full of crap, and proceeded to clean the PCs themselves. Big mistake!

          Oddly enough, their VP later complained to the service company I worked for that I had not done my job, since his IT people were fuck-heads. He didn't exactly state it this way, of course, but that was the gist of the statement. When I started to explain what had happened to my boss, I only got as far as "...and I discovered that most of their PCs were infected with Monkey-B."

          He started laughing, and finished my sentence for me with "and their stupid IT people went around removing it, right? Idiots!"

        Just code it to kill the connection after, say, fifty successful infections.

        You know what the real innovation would be, though? Writing an OS so that one process can't stomp on other processes it doesn't have permission to. It would also be nice to write something where worms couldn't just land on the system as executable files by default and scripts that do things like install other programs and do stuff without the user's knowledge can't be automatically run by a freaking e-mail program. Gee, too bad there's nothing around like that...

            *nods*

            Checking out the vulnerabilities used by Phatbot, I'm guessing most, if not all, of these holes were patched long ago. Short of forcing regular patching and upgrades, I guess there's not much that can be done to get around this. I get a shocking number of people through the store who never, ever use Windows Update.

            One part bad security model, one part careless users. Really, if there was an announced problem with your car that might lead to a thief getting in and driving off with it, wouldn't you get it fixed? Would you leave your door unlocked because it makes entering your car easier when you're in a rush?

            Computers have been sold as appliances, when they should be sold as flexible tools that aren't difficult to use, but take a minor bit of effort to maintain. I bet I could make big bucks just going to people's homes and carrying out basic upgrading and patching activities. $50/hr for running Windows Update, Ad-Aware and AVG, here I come...

              That's why people don't give a crap, cuz the machine still kinda runs. Most people probably chuck it up to: "God this old machine dosen't run like it use to could! I should have never upgraded to IE6."
          • Running WinNT, 2000, XP at user level is too restrictive. in *nix, if you need to install something it goes "hey feed me a password." In Windows it says "screw you, not enough privs." Then you have to logoff, logon admin, and do it.

            Furthermore, in Windows, there's a GREAT DEAL of things you can do in userland that should only be available in rootland. So because of these issues, I've ran every Windows computer I've ever owned at administrator level, as most people do.

                I've been in regular contact with an antivirus vendor's support people over 2 weeks trying to explain to them that it is NOT acceptable for users to have Power User privileges in order for their AV definitions to auto-update... It's like talking to a brick wall, here's an example of their 'support' verbatim:

                You may need to change the permissions on your c drive or the vet folder to everyone

                Double click on My Computer
                Right click on C drive

                Left click on properties
                Left click on Sharing
                left click on permissions
                Choose everyone a click ok
                Then click o.k

                Then perform an autodownload

                Double click on My Computer
                Double left click on the Vet
                Right click on C drive

                Left click on properties
                Left click on Sharing
                Then click on share this folder left click on permissions
                Choose everyone a click ok
                Then click o.k

                This should allow you to perform an autodownload.

                You may have to do the same on the c:\temp or c:\windows\temp
                folder or c:\document and settingsyour username\temp

                Sorry? Do you mean give everyone full control to my system drive, as well as your AV definitions, configuration files and executable code? You've got to be kidding!

                And surely you'd think that AV vendors would understand better than most the need for their software to operate under the principle of least privilege.

            Having absolutely everything running as an administrator is a huge mistake.


            Something else that really should be done is enforcing Intel's privilege rings.

            286+ processors have four privilege rings, 0 through 3. Processes running in ring 0 basically have root privs in the system, ring 1 processes can touch anything but those in ring 0, and so on.

            It's intended that critical OS functions, like the memory manager, run in ring 0. Device drivers and such live in ring 1, and user processes live in ring 3.

            Many operating systems, including Linux and all versions of Windows except NT 3.xx, run drivers in ring 0 because it's faster. However, it means that a bad driver can bring down the whole system. I bet the majority of Windows crashes lead back to crappy drivers, especially video drivers.

            Food for thought.

        This is your system administrator. DO NOT DELETE THIS E-MAIL. Your computer has been infected with the latest trojan worm rotovirus. Please take the following steps to remove this infection:

        1. Open your computer and remove the hard drive. If you are not able to do this on your own, ask the nearest IS worker for help. Inform him that this is to be done on direct orders from his superior.

        2. Attach the hard drive to a bat using duct tape. Beat yourself severely with it.

        3. While clutching the hard drive, run screaming down the hall.

        4. Forward this e-mail to all your direct reports. Please instruct them to comply IMMEDIATELY.

        Thank you for your assistance in stopping this infection.

        Sincerely yours,

        The Management
        OK, so maybe you can't get the hard drive to do it on its own, but if you make the e-mail look official enough, at least 10 people will do it for you.

    When a virus attempts to disable anti-virus and firewalls, there needs to be a better way to keep those programs operational and "clean". What if a virus altered your norton or mcafee to make it appear as though it is working(and not finding any viruses) when in fact it is not working at all?

    What if anti-virus, firewalls, and other critical software could somehow run in read-only memory space, which would have a physical barrier so that no bugs in software could be exploited to alter this space?

    What if we could "burn" memory space of a program to a CD rom so that a proper working, unaltered anti-virus and firewall could run without fear of being disabled?

        I don't see why actually. The problem seems to me to be the whole issue of windows users running as "admin" or "root" If people ran in user-space (or to be fair to users, if windows was set up to run easily and normally as a user rather than admin ) then no virus could easily affect any anti-virus software running as (if you are anal retentive about these things as unix tends to be not as root but as the "antivirus" user)

        I think macos X is a good example of an os that is pretty user friendly that doesn't encourage everyone to run as "admin". In fact there are no (by default) admin/root users, "admin" users are users that have sudo ability, so in a weird way its better than default redhat linux.

      There's an inherent problem there. Anything you can do to make your program read-only, an administrator can undo.

      So if Joe User gets infected and is running as administrator, the virus can un-write-protect memory and keep going.

      This is a classic offense vs. defense escalation and is the type of problem Rootkits pose as well.

    It's as bad as spam! It's EVERYWHERE!!

    I frequent a couple other message boards (damn, I almost said BBS'), and every few days, we get the same ol' thread...'VIRUS ALERT!!!!!!!'

    We live in the information age. The information has been disseminated that Windows users are:

    A) Prone to constant viral and security intrusions.
    B) In desperate need to constantly update their AV software.

    The SysAdmins who aren't keeping their servers locked down is another thing entirely...*grumble*

    But really, ABC, NBC, CBS, all these guys have done several stories on system security...EVERYONE's got a nephew that 'knows a lot 'bout dem 'puters'...

    I really don't understand why we're still being subjected to this crap. Virus news isn't news. It's spam.

      I see where you're coming from here. However, there's other considerations. Some of us must operate Windows boxes, so we must deal with it.

      Obviously the "security-by-news-alert" method of keeping your systems secure is stupid. We must still update our AVs and Spy cleaners and run them regularly. If we do that, we'll get almost every virus and spyware and never have to worry.

      But some of like to know what the virus writers are doing. Trends in the virus business, as they evolve.

      Some of us may have firewalls that we might wish to alter based on major recent virus activity. I'm sure the Blaster variants caused several admins to alter the RPC port configuration of their firewalls.

      Isn't it better to be proactive rather than reacting to a virus-based DOS?

      I agree, of course, that people shouldn't email their buddies "OMG VIRUS ALERT!!!111one!!11" as we are able to keep up on virus news ourselves. We don't need these emails.

    Just take a look at the feature list, it probably has more bells and whistles than most of the software out there.

    Is there a way to trace back the master of these trojans and do something about it? Surely these trojans need to do something for their masters at some stage, probably waiting for commands somewhere.

    The authors are getting better at designing control networks, but all it will take is one grayhat with an infected node to watch a command being executed and use that information to take out the entire botnet.

    Too bad it would be both grossly illegal and probably disruptive, because it would be a great favor to the rest of the net, to counter these botnets and squish-them into oblivion (at least this generation, until the attackers learn how to do authentication of commands correctly).

    This is also known as the "Agobot"

    http://news.yahoo.com/fc?tmpl=fc&cid=34&in=tech& ca t=hackers_and_crackers

    http://www.f-secure.com/v-descs/agobot_fo.shtml

    Detailed Description

    First of all, this new variant has 'Phatbot3' identifier and there are a few 'phat' string in its body. This may indicate that this version was not made by the original Agobot backdoor author, who calls himself TheAgo, but by a different person/group who got the source code of this backdoor.

    The backdoor's file is a PE executable 115738 bytes long compressed with PE-Diminisher file compressor. The unpacked file's size is over 245 kilobytes.

    Installation to system

    The Agobot.FO backdoor copies itself as NVCHIP4.EXE file to Windows System folder and creates startup keys for this file in System Registry:
    [HKLM\Software\Microsoft\Windows\Curren tVersion\Ru n]
    "nVidia Chip4" = "nvchip4.exe"
    [HKLM\Software\Microsoft\Windows\Cu rrentVersion\Ru nServices]
    "nVidia Chip4" = "nvchip4.exe"

    This allows the backdoor's file to start with every Windows session. On Windows NT-based systems the backdoor can start as a service.
    Scanning for vulnerable computers

    The backdoor can scan subnets for exploitable computers and send a list of their IPs to the bot operator. The scan is performed on ports 80, 135 and 445 for RPC/DCOM (MS03-026), RPC/Locator (MS03-001) and WebDAV (MS03-007) vulnerabilities. The backdoor can also scan for computers infected with MyDoom worm (port 3127), Bagle worm (port 2745) and also for computers where DameWare remote system management software is installed (port 6129).

    Performing a DDoS attack
    The backdoor can perform the following types of DDoS (Distributed Denial of Service) attacks:
    * HTTP flood * SYN flood * UDP flood * ICMP flood
    When performing a DDoS attack, the backdoor uses 33 unique client identifiers including Mozilla, Wget, Scooter, Webcrawler and Google bot.

    The backdoor sends 256000 bytes of random data to the following websites and checks the response times:
    www.schlund.net
    www.utwente.nl
    www.xo.net
    www.stanford.edu
    www.lib.nthu.edu.tw
    www.st.lib.keio.ac.jp

    Collecting e-mail addresses
    The bot can harvest e-mail addresses. It has the functionality to read user's Address Book and send the list of e-mail addresses to the bot operator.

    Obtainint Registry info
    The backdoor has the functionality to obtain System Registry info from an infected computer. This is a new feature for Agobot backdoor. Information obtained from the Registry can give a hacker a full overview of an infected system.

    Spreading to local network
    Agobot backdoor can scan computers on local network and copy itself there. The scan is initiated by a remote hacker. When spreading to local network, Agobot.FO probes the following shares:
    admin$ c$ d$ e$ print$ c

    Agobot.FO tries to connect using the following account names:
    (SEE LINKS AT TOP FOR INFORMATION)

    When connecting, Agobot.FO uses the following passwords:
    (SEE LINKS AT TOP FOR DETAILS)

    If the worm succeeds connecting to the above listed shares, it copies itself to a remote share and attempts to start that file as a service. The alternative way of infecting a remote host is to create a scheduled task on a remote computer that will start the backdoor's file.

    Teminating processes of security and anti-virus programs
    Agobot.FO has a huge list of process file names hardcoded in its body. The backdoor tries to terminate processes that have the following names:
    (NAMES REMOVED SO POST WOULD WORK, FOLLOW LINKS AT TOP)

    This functionality allows the backdoor to successfully disable anti-virus and security software that can not detect this backdoor before it's file is started. In most cases special tools are required to clean a computer infected with this backdoor.

It's pretty common; I wouldn't make anything out of it. It's quite possible that someone submitted the story before you did even earlier in the morning and the editors put that one in the queue to go up at 2:43PM. They pre-scheduled the various stories that go up hours (and sometimes even days?) in advance. Or perhaps they decided it was a worthy story after they saw the 27th submission of it.

      I realized one day that we could essentially have a user-contributed, user-moderated article queue of sorts using the journaling system here. I've dedicated my journal [slashdot.org] to it.

    How about a virus that does nothing but try to spread as far and wide as possible without doing anything malicious. Then, after a pre-determined ammount of time it would announce its presence to the luser and provide both instructions for its removal and common sense advice on how to avoid being infected by viri in the first place.

    Viruses spread due to stupidity, ignorance, and laziness on the part of users. A virus like this MIGHT help with the ignorance part.

    Now please don't think I'm advising anyone to go out and write such a thing, I'm only saying that I think the idea would be interesting.

    I think it would also be interesting to hunt down the creators of malicious viruses and have them drawn and quartered, preferably on live TV. Next their parents should be beat within an inch of their lives for not raising them right in the first place.

      Some AV companies consider this a variant of Agobot/Gaobot, since it shares a lot of the same code base. Which is funny, because when I analyzed Doomjuice and called it "MyDoom.C", they all said it was too different to be called a MyDoom variant (even though it was the same code with functionality removed).

      I consider the addition of the WASTE code and removal of the IRC code to be significant enough to call this by a new name. Not to mention all the other added features that are not part of the Agobot code.

    Here is a problem I had never thought about with open source initiatives. What happens when someone steals your source without obeying GPL or anything and turns it into a monster? It would have ben *MUCH* harder for the PhatBot authors to code their own Waste-like [slashdot.org] clustering P2P system. Perhaps they might not have even been able to do so. Instead they grab an open source app and use it to create something ilegal, and in this case even dangerous.

    These are the same problems faced in the emulation field. Many open source emu programmers do not allow any game from the past 2-3 years to be played, mainly to appease the corporations that still make arcade titles (SNK etc). But people open up their source and release renegade versions of their own apps without their permission and in violation of GPL and everything, often packaging them with illegal arcade ROMs.

    Hi Everyone

    As many people have pointed out there is an utter lack of response by the top three anti-virus companies to this threat. I find this disturbing and also, unlikely. Why would the Department of Homeland Defense have better intelligence on a clearly US based threat (Phat is not an international phrase by any means) than the people who make their lively hood based on threat detection and elimination?

    This has to me the markings of a hoax. The list of *features* as one poster put it is indeed staggering. That, coupled with the silence coming from Symantec, McAfee et al. makes it look fishy. A google search shows one recent post and a bunch of older hits (possibly the same as in the McAfee search ).

    So that leaves me with 3 questions:
    1 - Is it real
    2 - How do we detect it
    3 - How do we kill it.

      It's not. I spent several hours analyzing it. You can connect to the Gnutella cache servers and see Phatbot clients registered using port 4387. You can portscan the infected hosts, find the mini-ftp server it runs and download the code yourself if you need tangible proof.

      The list of *features* as one poster put it is indeed staggering.

      Most of these features are part of Agobot. Yet no one disputes its existence.

      That, coupled with the silence coming from Symantec, McAfee et al. makes it look fishy.

      They're not silent - to them this is just another Agobot variant, one of dozens released in the last few months. And they are not making a big deal about it because it really isn't that much of a threat. If you're running Windows with the latest patches and aren't infected with MyDoom or a Dameware backdoor and aren't using weakly passworded shares, you have nothing to worry about from this trojan.

      So that leaves me with 3 questions:
      1 - Is it real

      Yes.

      2 - How do we detect it

      With just about any AntiVirus solution.

      3 - How do we kill it.

      In terms of killing it from one machine: disinfect manually or use a tool from the AV companies. In terms of killing the entire network, you would need to reprogram the Gnutella cache servers it uses to detect and refuse connections from the Phatbots.

    Well, I suppose it's a lost cause (as with the "hacker" term), but I it can't hurt to point out that it really doesn't make much sense to call this program a "trojan".

    The article suggests that this is a "trojan" because it lets attackers stealthily take control of your computer. But that was not what was remarkable about the historical Trojan horse. What was remarkable about it is that it was presented as a gift. The distinguishing characteric of a trojan is that it has a friendly outward appearance but contains a deadly payload. That's certainly not the case with Phatbot.

    Rather, I'd say that Phatbot is a virus, because a) it is malicious and b) it doesn't rely on deception to spread itself. This is, again, subtly different from a worm, which generally aren't malicious, just annoying.

    Of course it's water under the bridge at this point.
