Poll trolls' GCHQ script sock puppets manipulate muppets

Stop and Thinkst: Is that really the Most Popular story or did haxxors Bash it out?

A group of security professionals/online miscreants have found and themselves created thousands of online accounts to manipulate forum posts, popular news articles and mailing lists using techniques pioneered by the UK's GCHQ spy agency.

Researchers Azhar Desa, Harron Meer and Marco Slaviero of Thinkst found posts created around controversial topics such as the Israeli-Palestinian conflict were being heavily manipulated by commentary developed by bash scripts using newly-registered accounts.

Using a since patched flaw in comment platform Disqus, researchers plucked email addresses from suspect profiles used in "sock-puppet" commentary and found those in question had identification numbers in sequence, were used across the same forums, repeated comments and bumped up each other's posts.

The identity of those behind the aliases was unknown.

The fake accounts were designed as supporters of Palestine and Islam, and opponents to Israel, Syria, Christianity and US President Barack Obama.

Researchers also found separate puppet armies influencing articles on Reddit, CNN, Al Jazeera and the Jerusalem Post generated by simplistic means that admins appeared unable to identify.

"Who is this sock puppet army? It's difficult to speculate – it's a simplistic attack, so we're not sure if this is because they lack the skills set, or if they were intending to be found," Slaviero told delegates at the Hack in the Box conference last month, (slides) Digital News Asia reported.

The team, which was developing free tools to let everyone troll more effectively, used similar techniques to successfully influence popular news stories on the front page of The New York Times, South Africa's popular Mail and Guardian, Reddit, and mailing lists.

You could create accounts and share an article from the same IP for about 10,000 shares, and then you switch to another IP again, and that was enough to bump an article up 15 or so spots (on the Times) from the bottom of the list, he told Risky Business in a podcast interview.

"We used one line in bash that allowed us to trivially create hundreds of [Disqus] accounts in a matter of seconds. The accounts are ordered by the number of likes so we could very easily bring a comment to the top or down to the bottom."

Once they discovered the weight each site placed on making a given post popular, such as the number of times emailed, shared on Twitter, or commented, they used bash scripts to manipulate popular posts.

In total they created 100 fake profiles on Disqus thanks they said to poor security, 30,000 on the New York Times, and registered Twitter profiles to pump out thousands of tweets, each slightly varied and containing a designated link.

The techniques were also used to successfully promote and downvote posts on some subreddits due to the fake commentary.

They posted fake emails to the popular Liberation Tech and Full Disclosure mailing lists in July using a control and experiment posts, the latter of which received replies from puppet accounts.

Unsurprisingly the email with sock puppet replies peaked the interest of humans receiving hundreds more hits than the control when results were tallied two days later.

Clicks fell as the pool of posts was diluted with 'distraction' emails from the scripts. ®

    Google won the patent battle against ART+COM, but we were left with little more than a toy

    Column I used to think technology could change the world. Google's vision is different: it just wants you to sort of play with the world. That's fun, but it's not as powerful as it could be.

    Despite the fact that it often gives me a stomach-churning sense of motion sickness, I've been spending quite a bit of time lately fully immersed in Google Earth VR. Pop down inside a major city centre – Sydney, San Francisco or London – and the intense data-gathering work performed by Google's global fleet of scanning vehicles shows up in eye-popping detail.

    Buildings are rendered photorealistically, using the mathematics of photogrammetry to extrude three-dimensional solids from multiple two-dimensional images. Trees resolve across successive passes from childlike lollipops into complex textured forms. Yet what should feel absolutely real seems exactly the opposite – leaving me cold, as though I've stumbled onto a global-scale miniature train set, built by someone with too much time on their hands. What good is it, really?

  • Why Cloud First should not have to mean Cloud Everywhere

    HPE urges 'consciously hybrid' strategy for UK public sector

    Sponsored In 2013, the UK government heralded Cloud First, a ground-breaking strategy to drive cloud adoption across the public sector. Eight years on, and much of UK public sector IT still runs on-premises - and all too often - on obsolete technologies.

    Today the government‘s message boils down to “cloud first, if you can” - perhaps in recognition that modernising complex legacy systems is hard. But in the private sector today, enterprises are typically mixing and matching cloud and on-premises infrastructure, according to the best business fit for their needs.

    The UK government should also adopt a “consciously hybrid” approach, according to HPE, The global technology company is calling for the entire IT industry to step up so that the public sector can modernise where needed and keep up with innovation: “We’re calling for a collective IT industry response to the problem,” says Russell MacDonald, HPE strategic advisor to the public sector.
