Nice catch, in the sense that LinkedIn was among the very few social networking sites left untouched by cybercriminals in 2008. With LinkedIn's staff actively removing the close to a hundred bogus profiles, let's dissect the campaign by exposing all the participating malware domains, the redirectors, the droppers' detection rates and the rest of the domains in their portfolio.Domains used on the bogus profiles :
sextapegirls .net (88.214.200.5)
celebsvids .net (216.195.57.47)
katynude .com (216.195.57.47)
delshikandco .com (82.103.132.114)
All the internal pages at sextapegirls .net (sextapegirls .net/1.html; sextapegirls .net/2.html; sextapegirls .net/3.html; sextapegirls .net/4.html; sextapegirls .net/5.html) redirect to hotvidz .info/5.html (88.214.200.5) as well as all the internal pages at celebsvids .net where TubePlayer.ver.6.20885.exe is served as a fake video player.Among the rest of the domains used, katynude .com/1.html (216.195.57.47) redirects to quickly-porn-tube .net/get.php?id=20885&p=74 (69.59.21.247) which then redirects to tube-4you-best .com/xxplay.php?id=20885 (69.59.21.247) where 2009download-best-soft .com/TubePlayer.ver.6.20885.exe (94.247.3.228) is again served.
The fourth domain used on the bogus LinkedIn profiles, delshikandco .com/movies/linkedin.html (82.103.132.114) once deobfuscated leads to delshiktds .com/in.cgi?6 (64.27.28.225), a traffic management kit's redirection point which redirects to delshiktds .com/in.cgi?11, celebs-online2009 .com/video.php (64.27.28.225) and megaporntubesonline .com/xplays.php?id=88 where codecdownload.filesstorage4you .com/exclusivemovie.88.exe is served next to codecdownload.viewersoftwarearchive .com/exclusivemovie.0.exe (94.247.3.232) which a copy of Win32/Renos.
The downloader then phones back to :dasgdasg .net (91.205.96.12)
new-york-images .com (89.149.207.114)
future-pictures .com (94.247.2.117)
download-everything.com (69.46.16.99)
archiveviewsoftware.com
193.142.244.17
Naturally, the people behind this malware campaign have centralized the rest of the malicious domains by parking them at the very same IPs used in the redirectors. The domains are pretty descriptive themselves, and it's also worth pointing out that they intend to start introducing newly registered fake security software ones:
