Link farmers bust Google search algos

[Batu69]

And just for a change, PDFs are part of the problem although Adobe's blameless for once

Sophos threat hunter Dmitry Samosseiko says attackers are hacking sites and implanting hundreds of thousands of malicious PDF files a day to build a new cloaking system that foils Google's search algorithm analysis.

Samosseiko says the blackhat search engine optimisation method applies old keyword-stuffing and link-spamming tricks for HTML to PDFs.

It works because Google's revamped blackhat-nixing Panda algorithms,used to uncover and eliminate those tricks from web pages, are not applied as rigorously to PDFs.

Hackers can top search rankings by compromising legitimate sites and planting PDFs that reference their own dodgy sites.

"Our discovery of a new search poisoning method came from a Sophos Antivirus detection that Jason Zhang of SophosLabs created based on a suspicious-looking PDF file," Samosseiko says.

"In short order, we received hundreds of thousands of unique PDF documents per day that triggered this detection.

"When doing a Google search for keywords found inside those PDFs we found a large amount of similar documents on a number of legitimate, but unrelated and likely compromised, websites."

Samosseiko says the link farm method, or back-link wheel, is targeting binary trading brokers which are commonly flogged on shady sites such as The Pirate Bay.

A search for 'binary trading Austria' and 'safe stock trade US' yields a front page full of blackhat link farming PDFs.

While the binary bashing is a nuisance, the method could become highly dangerous if it is adopted by enterprising exploit kit brokers who are fast to exploit emerging opportunities.

Samosseiko sent the findings to Google ahead of disclosure.

Adobe can be to blame as somehow get 5 stars on this report that is missing tons of info Who HAs Your Back while making the softwear that has so many holes in it constantly that you could put probably the whole united states in. Also Apple did this

Apple iTune s flaw 'allowed government spying for 3 years

and there are other articles out there that have apple spying on your listening habits and sending them to their server without asking first.

same with many of the companies listed

The Government Is Spying On Us Through Our Computers, Phones, Cars, Buses, Streetlights, At Airports And On The Street, Via Mobile Scanners And Drones, Through Our Smart Meters, And In Many Other Ways

who receive stars.

Anyways, back to the article in question, it says binary brokers. What this means is not specifically the brokers for say, but the people that would use the brokers to deposit money with aka intercepting their info and then probably charging their credit card or draining their bank account.
