Anyone who's been reading this forum knows that I've been keeping an eye on Blogspot for malware
since August. And before that even by about 3 weeks,
PG wrote some up @ Spyware Guide.
I then followed up with write ups
early September and again
mid September and the latest being
November.
Since then, I've been peeking in here and there and had not found anything in a malware nature, tho that's not to say there surely wasn't
tons of splogs being documented by Chuck, it just meant no malware was being pushed.
Well after reading
this over @ Sunbelt blog about fake codecs, nothing I was surprised to hear based on my previous outings I decided to take a hike thru Blogspot land to see what I could snag.
Well I can't say I was disappointed. As a matter of fact, they even made it easy for me to find the malware, once I noticed there was a pattern.
If you were to click on any Blogspot blog that a specific word in it, you got hit with some fun stuff. I'll not tell you the word to avoid anyone getting curious.
Oh and I'm not talking about fake codec here, where users get prompted to install something, using the ol' 'social engineering' trick, no sir, just by landing on any of these sites (over a dozen) you got dumped on the system a few files. The obvious ones were like these entries from a HJT log:
Quote:

O20 - AppInit_DLLs: sol664.txt
Now the lines in 07 and 020 may have been from another malware run, I'll have to double check in the morning, but those others were dropped each time, all the ones which began with 'a'. I scanned all @ VT, but it seems someone else had found them at about the same time as I had, because almost each one had a scan date of 12-27.
Here are the few I snagged:

And most all of the files which were already scanned, had similar results, not real bad, but not real good either.
I noticed that all the sites ran calls out to the same sites too, and a few, even went to our friends at
Inhoster, over in the Ukraine. They are very well know malware\rogue hosting company. Very likely linked to the
RBNSo be sure and stay away from the 'Next Blog' button, because these site are littered all thru the Blogspot world.
Tomorrow I'll do some more digging around to see what if anything has changed.
