| My.yahoo downloading trojan's? It appears to have started today but going to my yahoo page is linking to plgou.com/csrss/yahoo.htm and trying to download some trojans. I noticed another thread on answers.com where another person was having the same issue and it just started today.
Anyone else seen this? | |

| Re: My.yahoo downloading trojan's? MyYahoo is the personalized page yahoo users can create if they have an account.
Email, weather, personalized news, etc.. The user puts it together by selecting modules and colors.

I am using IE7 fully patched but haven't been back there lately as I am trying to remove the nasties from my machine. When launching IE normally it creates subs called sss.exe, beauty.exe and fengxing.exe that I see in process explorer. Under limited user, those don't launch. | |

| Re: My.yahoo downloading trojan's? I do not doubt what you are saying I just answered your question on how MyYahoo worked for me.
Other members that use MyYahoo will no doubt chime in and let you know their results.

1 edit | I haven't used that in quite awhile, but can't you put "unsupported" modules on your page? Maybe someone's IFRAME or some module is redirecting to some bad site. I'd remove all questionable modules and start over with your page customization.

| Hello,
Yes, I have seen these exact symptoms. In addition, I saw that IE wanted to load the chinese character set and some kind of popup window appeared with a chinese looking name on it. It's either chinese dissidents or chinese gov't behind it. After deleting the previously mentioned files in system32, The b**tard hosed something to do with my Internet access. I can ping everything, but IE and Outlook Express won't work. I installed Firefox and that wouldn't work either. I haven't done anything else, but it looks like I'm going to have to run XP repair. I'm guessing it replaced one the Microsoft dll's related to http, probably a redirector of some kind. Everything works from my other computer so that's confirmed.
One thing I've noticed about my.yahoo.com since I started using it is that it actually goes to cm.my.yahoo.com; that's happening with Yahoo's explicit permission. They've farmed my yahoo out to Mainland Chinese programmers (not surprising since the CEO is chinese) and now that anally retentive Chinese premier has put gov't programmers on "payback" detail to western journalists for stirring up trouble... us poor my.yahoo.com saps got taken along for the ride... just a theory. | |

Is that what the "cm" stands for? I always wondered what that stood for. Actually, I only saw that when the new My.Yahoo page was in beta. I don't see the "cm" anymore.
Back on subject. My.Yahoo working ok here with Firefox and IE. | |

Try using open DNS (www.opendns.com) and see if it fixes the problem. | |

| I started having the same problem at around the same time. I found that an RSS feed, that I had setup on my Yahoo home page, may have been causing the problem (i.e., techbargains.com).
when I tried to go to the site directly, I found:
Techbargains.com is undergoing maintenance right now.
Come back soon!
I deleted the RSS feed from my Yahoo home page, the problem went away (no more links to plgou.com) and no more McAfee warnings of trojans.
I am thinking that maybe the site got hacked, and they are trying to fix it. This was one of my favorite feeds, hope they fix it. | |

| Well if (& assuming) this type of code is being injected into Yahoo (my.yahoo.com) web pages, isn't that going to be a vulnerability that exists on Yahoo's end (on their servers/softwares)?
Or could it be caused by code the end user placed into their page?
I gather if you have this patch installed, you're likely to be less vulnerable.

Further, as it appears to use vbscript/ActiveX, using a Mozilla browser would render the page ineffective. | |

| I found an interesting article regarding Iframe's on CA's website. Here is a link as to what was happening and will probably continue to happen for at least a bit anyway.

I still haven't gotten Outlook Express or *any* browswer working again, so they must have hosed some of my Internet access files before I killed their script. I've re-applied XP sp2, but this is "Home" edition, so if want to re-install XP, I've got to obliterate my HD. Oh why didn't I switch to Linux like my mother told me to?... | |

1 edit | Yes multiple problems yesterday and today. Our AV product is intercepting the trojan and disabling it. In some cases this action also disable IE.
When I shut and restart IE the problem corrects, but if you visit "My.yahoo" again, it happens again every time. Easily replicable. | |

1 edit | As japiscan00 above said, the trojans were as a result of an
attack on Techbargains. Anyone who had their RSS feed in
their MyYahoo page would have gotten the virus warnings from
their AV (or the trojan if it wasn't detected). Sandi

The msyahoo.exe file, downloaded as rondll32.exe, installed hidden programs and commands that made some resources in users' computers available to hijackers. sans.org notes that these files, msyahoo.exe and rondll32.exe surfaced in their current SQL injection analysis, which may be linked to the techbargains.com exploit:

EDIT: In the above diary, scroll down to the "yahoo.htm" analysis. The script code is the same as the code for the plgou.com/csrss/yahoo.htm site you mentioned in your post.

| Re: My.yahoo downloading trojan's? A user on another forum i visit, found this plgou SQL injection website 2days ago(i think), i did a little bit of seeing exactly what the files do
Theres 2 dif files hosted there, one on the csrss area, that file is the worse of the two, it downloads 3 more files, and tries to run a 'sl.exe', my VM currently runs on crappy vista so i couldn't investigate further, but if you were hit, you may wish to look for sl.exe(no guarentee it may change filename/delete after run)
