Dissecting the Ongoing U.S Federal Forms Themed Blackhat SEO Campaign


AltusHost Inc, the company whose services were exclusively used in the blackhat SEO campaign using U.S Federal Forms theme for scareware service purposes, has finally responded to the abuse notifications sent seven days ago stating that "the sites have been terminated". Such a slow response once again proves that dysfunctional abuse departments increase the lifecycle of a malware/spam/phishing campaign by not taking it down when it's most actively gaining momentum.

(For historical OSINT research, the following domains not previously listed were in circulating during the past week - thwovretgi .com - 91.214.44.239 - Email: joby47619@msn.com; shtifobpy .com - 91.214.44.210 - Email: hiraldo13686@hotmail.com; vodcotha .com - 91.214.44.203 - Email: jamarcus59884@yahoo.com; stromiko .com - Email: hyacinthiemccolman@gmail.com; ceslyemsof .com - 91.214.44.205 - Email: brisco68781@lycos.com;  ejeifyevy .com - 91.214.44.208 - Email: brisco68781@lycos.com; kuhatjidd .com - 91.214.44.203 - Email: khrista12110@hotmail.com )


How did the cybercriminals respond? By proving that this blackhat SEO campaign has been well planed and coordinate a long time before it was executed in the wild. For the time being, it relies on a combination of legitimate U.K based sites, the result of a evident compromise of Web Hosting Mania due to the fact that all the affected legitimate sites are hosted there, a growing portfolio of .cc tld domains, automatic abuse of free services such as myftpsite.net; dns2go.com; dynodns.net; thebbs.org, and systematic pushing of new scareware variants/redirector and scareware domains, which explains the low generic detection rate of all the samples obtained.


Moreover, not only did the blackhat SEO themes expanding in the typical randomly generated junk that has naturally been crawled by public search engines, but also, according to publicly obtainable statistics, millions of users (collectively) have already visited the landing sites, with 42.80% of the referring site for a particular domain coming from thebbs.org and 31.97% from Google - their tactics are actively hijacking millions of users already.


Let's dissect the latest developments in the ongoing blackhat SEO campaign, list the participating scareware/blackhat SEO/redirection domains, the various monetization tactics going beyond scareware, as well as discuss some of the innovations used in the javascript obfuscation which makes it virtually impossible for a crawler to detect that the site is malicious.

Key summary points:
  • U.K based hosting provider Web Mania Hosting appears to be compromised due to the fact that all the abused legitimate sites are hosted there
  • the redirection and scareware domain/binary are updated two times during 24 hours period of time
  • all the scareware samples continue phoning back to several domains parked at 78.46.201.90
  • the cybercriminals have introduced multiple monetization tactics through pay-per-click malware-friendly search engines
  • sampled scareware adds the following registry entry [HKEY_LOCAL_MACHINE\SOFTWARE\6A36EA6E11EAAECDF5E540DEF2149079] plxxh = "Dujaq!!" - Dujaq!! means "Bl*w me!!"

Among the new monetization tactics used are the typical pay-per-click malware-friendly search engines which act as both, redirectors to phony sites/scams, as well as keyword blackholes which help them assess the popularity for a particular keyword, and therefore start pushing it more aggressively through a process called synonymization.

Interestingly, they're exclusively using the compromised .co.uk, as well as purely malicious blackhat SEO domains for scareware serving purposes, but continue using the ones they operate under the free DNS service providers for monetization through the bogus search engines. The domains used in this monetization approach are as follows:


rivasearchpage .com - 64.27.21.5 - Email: support@ruler-domains.com
triwoperl .com - 95.168.191.19 - Email: florenzaluwemba@gmail.com
tropysearch .us - 74.52.216.46 - Email: tech@add-manager.com
glorys .info (glorys .info/red/cube.js) - - 78.159.97.186 - Email: kor4seo@rambler.ru
funnyblogetc .info/go.php -  - Email: tigerwood1@nm.ru


triwoperl.com's front page is currently relying on the go.live.com javascript obfuscation. Deobfuscated it redirects to fi97 .net/jsr.php?uid=dir&group=ggl&keyword=&okw=&query=", deja vu again - fi97 .net was used in the Ukrainian "fan club's" blackhat SEO campaign in June.

Monitoring of the campaign and takedown actions would continue, with an emphasis on the RBN connection from a related blackhat SEO campaign from last year. The gang is not going away anytime soon, but their campaigns definitely are.
