Conficker
Worm Shipped With Police Body Cameras
Police
body cameras acquired from Martel Electronics have been found to be
infected with the notorious Conficker worm.
… Florida-based
IT services provider iPower Technologies has been working
on developing a cloud-based system
for police departments and government agencies to store and manage
video from their cameras. While analyzing the Martel Frontline
Camera, a body cam designed for police departments, iPower discovered
that the devices acquired by the company for testing had been
infected
with a variant of Conficker, a threat also known as Downup, Downadup
and Kido.
The
company’s tests showed that a functional version of Conficker had
been shipped with multiple cameras. Once the cameras were connected
to a computer, the malware attempted to spread to other machines on
the network and communicate with a command and control (C&C)
server.
Can
you trust a Twit?
Technology and social media companies are pushing
out an ever-increasing amount of data to tally up which 2016
presidential candidates are winning the race for most mentions
online.
But pollsters and other observers caution these
new metrics are not a reliable gauge of support for a candidate and
are not necessarily a reflection of the state of the race.
“They offer information, but we don’t know if
they are representative of the electorate,” said Duke University
professor Sunshine Hillygus, who focuses on survey methods as well as
technology and politics.
Neil Newhouse, the Mitt Romney campaign’s lead
pollster in 2012, says his industry does not ignore the data, but it
has to look at it skeptically.
… “And so there are lots of people now
studying Twitter and Facebook and the number of people at rallies,”
Hillygus said. “Unfortunately, all of those have this degree of
self selection — right, where people are choosing to put a post, a
tweet, about politics. And unfortunately we have found that they are
considerably biased. They
are biased towards those people who are engaged and more extreme in
their views and polarized.”
“I would bet there are very few moderates on
Twitter,” Newhouse added.
… Some studies in recent years have touted
the predictive powers of Twitter in congressional elections, but
critics have noted that
most of the main forecasting in those models can be traced back to
incumbency and the political leanings of a district.
A recent study factored in the growth of a
candidate's Facebook likes and engagement into a traditional
forecasting model to predict 2012 Senate election winners.
The technique outperformed a traditional model.
The
study concluded that the “question remains, however, whether
these results are a ‘flash in the 2012 pan’” or a broader
indication of the effectiveness of the technique.

– The
True Measure of Bitcoin’s Success – This commentary by
financial analyst Ryan Davis supports the position that the price of
Bitcoin should not be the primary measure of the state of Bitcoin,
nor should any one metric be the primary measure of the state of
Bitcoin. The true measure of the state of Bitcoin is a combination
of everything from activity in GitHub repositories to the number of
daily bitcoin transactions.

Derivatives – Independent Study Report – Financial analyst
Ryan
Davis describes the landscape of exchanges based in and outside
of the U.S. that have begun to offer trading in bitcoin derivatives.
TeraExchange completed the first bitcoin derivative trade on a
regulated exchange in the U.S. on October 8, 2014 with its Bitcoin
Non-Deliverable Forward (NDF) contracts. More recently, LedgerX has
submitted applications to become the first regulated bitcoin options
exchange in the U.S. Additionally, some exchanges are based outside
of the U.S. but may have significant customer bases in the U.S.
Bitcoin derivatives offered on these exchanges include futures,
forwards, and options.
