“Blackhat SEO Campaign Hijacks U.S Federal Form Keywords, Serves Scareware”
SNIPPET: “During the past 24 hours, a blackhat SEO campaign has been hijacking U.S Federal Forms related keywords in an attempt to serve scareware.
What’s particularly interesting about the campaign is that the Ukrainian fan club behind it — you didn’t even think for a second that there’s no connection with their previous campaigns, did you? — are using basic segmentation principles since the tax form keywords poisoning is attempting to hijack U.S traffic. Evasive practices are also in place through the usual http referrer check, which would only serve the scareware if the visitor is coming from Google.com, if not a 404 error message will appear.”
