A reader alerted us to a bunch of malware that he had found after starting to unravel a pile of interlinked exploit pages. The exploit pages are spammed with "adult movie" kinda themes into search engines, etc, and thus most likely find enough "volunteers" who click on the links.

Domains involved are clipsforadults-dot-com and several of 9u???-free-movies-dot-cn, with the ??? standing for several letter combinations like eyd,gfo,fdo, etc. Someone's been busy registering throw-away domains.

The one bit that was of interest to us is ... that at the very end of this pile, the links try to download a "codec" off the site installobject-dot-com. The link used contains a 4-digit number, and each number, over a wide range, seems to return a slightly different binary.  Installobject-dot-Com resolves to, a known bad address range for years - see

AV detection is still thin, we are trying to help it along some. The files are of the W32/Zlob family, Kaspersky calls it Trojan-Downloader.Win32.Zlob.bxt, Trend Micro has it as TROJ_ZLOB.DND, and McAfee has protection coming up as Puper.DR

Adult sites from China, nasty trojans from Ukraine - the Malware Megabucks International, Inc, at its best.
