Hackers Could Crash Trains by Hacking Rail Traffic System

The Hacker News -

After reaching heights in cyber attacks by targeting SCADA systems, hackers are looking forward to crash trains. It isn't only assumptions; it could actually happen in real. A new hi-tech railway signalling system being tested in the United Kingdom could potentially be hacked by cyber criminals to cause oncoming trains to crash into one another at highest speeds, an Internet security

by Christopher Whalen at The National Interest The minimum takeoff or “vertical rotation” speed (Vr) of a fully loaded Boeing 777 airliner is about 155 knots (175 mph) at sea level. If the pilot attempts to pull back on the stick and lift off the runway before reaching Vr speed, then the plane is likely to smash its tail into the tarmac and possibly even crash. This aeronautical example is also applicable to monetary policy. For more than a year now, economists have been predicting that the Federal Open Market Committee would soon increase interest rates—this after seven years of near-zero short-term money rates. Investors and economists alike greatly desire to see a Fed rate increase as a sign that the U.S. economy has recovered from the 2008 market collapse. But because economic consumption and demand for credit remain anemic, and debt levels in the industrialized nations have actually increased since 2008, any attempt by the Fed to achieve “lift off” in terms of raising interest rates is likely to result in an economic stumble. The current debate about the direction of monetary policy is proceeding as though the U.S. economy were actually recovered. Some FOMC members and market observers want to see a rate hike to forestall increased inflation, an ancient fear that seems to be ill-considered. The global economy is still confronted by excessive debt and secular deflation, perhaps not in terms of prices for financial assets, but certainly when we look at wages, employment and commodity prices. Indeed, despite the efforts by the Fed to reflate the global economy, the United States seems to be suffering from a prolonged period of slack demand, low investment and weak prices for key industrial inputs. For the past several years, the FOMC has maintained a target of 2 percent inflation as one of the indicatorsOriginally appeared at: http://davidstockmanscontracorner.com/the-feds-day-of-reckoning-nears/The Fed\'s Day Of Reckoning Nears is a story from: BitcoinWarrior.net

Bitcoin Exchange ItBit Seeks New York Banking License

Bitcoin feeds -

In a little noticed move, bitcoin exchange itBit has filed for a banking license in New York, according to the state banking authority. Approval for the license may come in the next couple of weeks, people familiar with the matter told Reuters, which could make itBit the first bitcoin company to be regulated as a bank in the United States. The application is part of itBit\'s plan to expand its business into different corners of financial services, and present itself as a trustworthy and reputable company. Right now, itBit operates as an exchange where buyers and sellers trade the bitcoin digital currency. After a series of scandals that have roiled the virtual currency markets, reassuring customers, investors and bitcoin market participants is critical. Last year, rival Mt. Gox filed for bankruptcy after its computer system was hacked, and prominent bitcoin advocates had been accused of money laundering. “Some highly publicized failures and potentially illegal activity have focused attention on virtual currencies and have highlighted the need for a sound regulatory framework for virtual currencies,” itBit Chief Executive Charles “Chad” Cascarilla said in an October letter to New York\'s state banking regulator on an unrelated matter. ItBit, whose exchange operates in Singapore, moved its primary headquarters to New York last year, and hired Erik Wilgenhof Plante from eBay as chief compliance officer. The company\'s website touts its anti-money laundering efforts and “know your customer” credentials, as well as its compliance in all jurisdictions in which it operates. “Whether fairly or not, companies that work within the regulatory framework are more trusted by customers and partners,” said David Berger, CEO of the Digital Currency Council, an industry advocacy group.

Bitcoin Exchange itBit Looks to Get New York Banking License

Cryptocurrency exchange itBit is expected to become the first bitcoin firm in the US regulated as a bank, as the company has filed for a banking license in New York. According to people, familiar with the process, the license is likely to be approved in the following two weeks, Reuters reported. The move is in line with the company\'s plan to enlarge its business and broaden a range of services in the financial sector. In 2014, itBit moved its headquarters from Singapore to New York and appointed Erik Wilgenhof Plante, former Senior Compliance Manager at PayPal, as new chief compliance officer. “Some highly publicized failures and potentially illegal activity have focused attention on virtual currencies and have highlighted the need for a sound regulatory framework for virtual currencies,” said itBit CEO Charles Cascarilla in a letter to New York\'s state banking regulator last year. New York state\'s superintendent of financial services, Benjamin Lawsky, has always advocated for regulating companies using the digital currency and the blockchain technology. The license application includes the names of prominent figures in the financial and political circles, including former Senator from New Jersey Bill Bradley, former Chairman of the Financial Accounting Standards Board Sheila Bair and former Financial Accounting Standards Board Chairman Robert Herz. The organizers are liable for establishing limited liability companies in the state of New York, although they don\'t hold positions in these companies. Besides, the list of organizers includes ItBit CEO Charles Cascarilla and the founder of Liberty City Ventures Emil Wood, who together with Cascarilla opened the investment company Cedar Hill Capital Partners. Many in the financial industry still don\'t perceive bitcoin and other cryptocurrencies in a serious way, considering it is used mainly by teenagers and gamblers.

How and Why the U-Pick Game Marathon Raises Money With Non-Stop Gaming (Video)

Slashdot -

On June 12 through 14th of this year, the fourth (not "fourth annual," but close) iteration of the U-Pick Video Game Marathon for Charity --“UPickVG IV” for short --will be streaming on an Internet connection near you. The U-Pick crew's volunteers will be playing and broadcasting video games, non-stop, as a fundraiser for Charity Water, a cause they've supported since the beginning. I talked with organizers Stephanie and Grant Kibler from their video-game lounge of a living room about what it takes to broadcast an online gathering like this, and why they've adopted this as an annual event. Hint: some esoteric video-capture hardware helps, and so does a beefy network connection, for high-quality streaming of games that pre-date today's multiplayer, network-oriented options. That's significant, because U-Pick's stable of titles isn't limited to modern ones, and observers are encouraged to suggest appropriate games (hence "U-Pick").The remote viewers' choices and donations influence the event by deciding which games are represented on the Wheel of Destiny that the team spins to decide which games get played.The play itself, though,*is* limited to the players who'll be on hand at a Northern Virginia co-working space that will serve as this year's venue. It turns out to be easier to stream the output of old consoles than it is to control them from remote (never mind the latency that would mean), but maybe one day participants will be able to play as well as shoulder-surf and laugh at the players' running commentary. You can check out the Upick page on Facebook, too, and watch one of their practice runs each Sunday. (Note: Video #1 talks mostly about the game play and how you can join. Video #2 - below - talks more about hardware and behind-the-scenes work.)

Five Disturbing Things You Didn’t Know About Forensic “Science”

The Intercept -

Last week, The Washington Post revealed that in 268 trials dating back to 1972, 26 out of 28 examiners within the FBI Laboratory’s microscopic hair comparison unit “overstated forensic matches in a way that favored prosecutors in more than 95 percent” of the cases. These included cases where 14 people have since been either executed or died in prison.

The hair analysis review — the largest-ever post-conviction review of questionable forensic evidence by the FBI — has been ongoing since 2012. The review is a joint effort by the FBI, Innocence Project and the National Association of Criminal Defense Lawyers. The preliminary results announced last week represent just a small percentage of the nearly 3,000 criminal cases in which the FBI hair examiners may have provided analysis. Of the 329 DNA exonerations to date, 74 involved flawed hair evidence analysis.

While these revelations are certainly disturbing — and the implications alarming — the reality is that they represent the tip of the iceberg when it comes to flawed forensics.

In a landmark 2009 report, the National Academy of Sciences concluded that, aside from DNA, there was little, if any, meaningful scientific underpinning to many of the forensic disciplines. “With the exception of nuclear DNA analysis … no forensic method has been rigorously shown to have the capacity to consistently, and with a high degree of certainty, demonstrate a connection between evidence and a specific individual or source,” reads the report.

There is one thing that all troubling forensic techniques have in common: They’re all based on the idea that patterns, or impressions, are unique and can be matched to the thing, or person, who made them. But the validity of this premise has not been subjected to rigorous scientific inquiry. “The forensic science community has had little opportunity to pursue or become proficient in the research that is needed to support what it does,” the NAS report said.

Nonetheless, courts routinely allow forensic practitioners to testify in front of jurors, anointing them “experts” in these pattern-matching fields — together dubbed forensic “sciences” despite the lack of evidence to support that — based only on their individual, practical experience. These witnesses, who are largely presented as learned and unbiased arbiters of truth, can hold great sway with jurors whose expectations are often that real life mimics the television crime lab or police procedural.

But that is not the case, as the first results from the FBI hair evidence review clearly show. And given the conclusions of the NAS report, future results are not likely to improve. What’s more, if other pattern-matching disciplines were subjected to the same scrutiny as hair analysis, there is no reason to think the results would be any better. For some disciplines the results could even be worse. Consider the examples below:

1. Bite-mark analysis is based on two falsehoods and has wrongfully convicted at least 24 people

“Hair comparison analysis is practically DNA compared to bite mark analysis,” says Chris Fabricant, director of strategic litigation for the Innocence Project. Bite-mark analysis — generally the practice of identifying alleged bite marks on human skin and then matching the pattern left behind to a person’s dentition — relies on two basic assumptions: One, that human dentition, like DNA, is unique; and two, that human skin is a good medium for transferring and preserving a bite-mark impression. But as it turns out, neither is true, according to research conducted by Mary Bush, a professor of dentistry at the State University of New York at Buffalo, who, with her team, has conducted the only actual scientific inquiries into the practice in decades.

Indeed, some of the harshest criticism contained in the NAS report focuses on bite-mark evidence, and concludes that there is no scientific underpinning to the discipline. In a recent four-part series on bite-mark analysis, The Washington Post’s Radley Balko described how forensic odontologists — dentists who profess expertise in bite-mark analysis (and who are qualified as such by the American Board of Forensic Odontology) not only reject the NAS’s conclusion, but actively attack anyone who dares to criticize the field. Two examples: In 2013, ABFO leadership orchestrated an aggressive — and ultimately unsuccessful — plan to expel their own colleague, Dr. Michael Bowers, from membership within the American Academy of Forensic Sciences, which would have hamstrung Bowers from testifying against the practice in court. His crime: being a vocal critic of bite-mark “science.” In 2014, speaking at an ABFO dinner, Manhattan prosecutor Melissa Mourges, a strident supporter of bite-mark evidence, not only derided Mary Bush’s work, but also peppered her remarks with petty insults about Bush’s physical appearance.

Of course, as it is with hair analysis — and, really, any of the questionable forensic disciplines critiqued by the NAS — the utter lack of a scientific foundation has done nothing to keep bite-mark evidence out of the courtroom. To date, DNA has exonerated 24 individuals sent to prison on bite-mark evidence.

2. Dexter lied to you about blood spatters. They sow chaos and confusion.

In the popular Showtime series Dexter, serial killer of serial killers Dexter Morgan has a day job with the Miami police, where he works as a blood-spatter analyst. The episodes show him expertly analyzing sprays of blood on walls or drops on floors, quickly — and reliably — arriving at a concrete theory of the crime that, more often than not, leads the PD’s homicide detectives to swift resolution.

If only it were that easy.

While there is some actual science involved in bloodstain-pattern analysis — knowledge of the physics of fluids is helpful, as is an understanding of the pathology of wounds — the sheer number of variables involved in the creation of any given bloodstain makes reaching any definitive conclusion about the circumstances of its origin difficult at best. “The uncertainties associated with bloodstain pattern analysis are enormous,” the NAS report concluded.

Yet for defendants, as with other forensic disciplines, the conclusions of a bloodstain “expert,” can mean the difference between living free or behind bars. The NAS report warns that while science supports “some aspects” of bloodstain-pattern analysis — whether blood “spattered quickly or slowly” for example — some experts “extrapolate far beyond what can be concluded.” This risk was powerfully demonstrated in the bizarre case of Warren Horinek, a former Fort Worth, Texas police officer who, based solely on the conclusions of a blood pattern expert, was convicted and sentenced to 30 years in prison for the 1995 murder of his wife — a death that the police, medical examiner, and prosecutor all concluded was actually suicide.

Horinek remains in prison.

3. Worn shoes and tires can land you on death row, but there’s no evidence they’re unique

Among the most common pattern-matching evidence found at crime scenes are shoe prints and tire tracks. Although, generally speaking, soles and tire treads are decidedly not unique, since both are mass produced — 299 million tires were sold in the U.S. in 2013 alone — a combination of factors allegedly transform these common items into unique pieces of evidence for courtroom purposes. Uniqueness is derived from the degradation of these items from normal wear and tear, cuts, scrapes or other factors.

There are several problems with this type of evidence — not least of which is the fact that while the evidence found at a crime scene remains static, fixed in time, shoe and tire wear is continuous, meaning in part that unless you can immediately match a shoe or tire to a crime scene, the potential probative value of that evidence could quickly be irretrievably lost. But more concerning is that there is no science demonstrating that any particular marks are actually unique, nor are there any standards for how many unique characteristics it takes to declare a match between object and evidence. There is “no defined threshold that must be surpassed, nor are there any studies that associate the number of matching characteristics with the probability that the impressions were made by a common source,” reads the NAS report. “Experts in impression evidence will argue that they accumulate a sense of those probabilities through experience, which may be true. However it is difficult to avoid biases in experience-based judgments, especially in the absence of a feedback mechanism to correct an erroneous judgment.”

Indeed, spurious shoe print evidence offered by an FBI examiner helped to send Charles Irvin Fain to death row for the 1982 kidnapping, rape and murder of a 9-year-old girl in Idaho. According to the examiner, wear on Fain’s shoes matched wear patterns in shoe prints connected to the crime — and those wear patterns, the expert concluded, were created by a person with a particular gait. The perpetrator would “have to have the same characteristic walk as the individual who owned those shoes,” the expert testified.

DNA testing ultimately led to Fain’s release from prison in 2001 after spending 18 years on death row.

4. No two fingerprints are alike? That is the question

(Thomas Kienzle/AP)

ASSOCIATED PRESS

Perhaps no area of forensics is more familiar to people — or outside DNA, more believed to be infallible — than fingerprint examination. The practice has been around for more than a century, and its ubiquity and repetition, combined with the mere passage of time, has helped to cement fingerprint matching’s reputation. The problem is that this practice, too, is an entirely subjective endeavor — and it is only recently that there has been any serious scientific inquiry into its validity. “No two prints are alike,” experts will say, but there’s no actual proof that is true.

Importantly, fingerprints collected from crime scenes are often only partial prints, distorted, smudged, or generally “noisy,” as one group of investigators, seeking to formulate error rates for fingerprint examination, wrote last year. And that’s where problems can happen: Consider the case of Brandon Mayfield, the Oregon lawyer who was falsely accused of participation in the 2004 Madrid, Spain train bombings based on a fingerprint collected from a bag containing detonation devices. The FBI later admitted it bungled the print match.

Fortunately, there are ongoing efforts underway within the discipline’s community of experts to validate forensic fingerprint examinations. Jennifer Mnookin, a UCLA law professor and lead investigator into fingerprint error rates, says that leaders in the field have begun to embrace the emerging “research culture” that the area is taking on. “At this point it’s not that the work is done,” she says. “It isn’t. But compared to bite marks…to handwriting [analysis], there is now a growing body of research looking at these questions [of validity and reliability] in a way that didn’t exist 10 to 15 years ago.”

5. The FBI trained an army of local hair-analysis charlatans

(University of Rhode Island)

Although it is certainly a good thing that the FBI agreed to undertake a review of the work of its hair examiners — and then to clearly and publicly declare the miserable results — there is a deeper and even more troubling truth about the hair analysis revelations: There are potentially tens of thousands of additional cases out there that will not necessarily ever be reviewed. That’s because the FBI examiners for 25 years provided training to hundreds of hair examiners across the country — training that included the demonstrably, scientifically-flawed language that has been exposed in the current, and ongoing FBI case review.

Whether all of the state cases will ever be identified let alone reviewed, remains to be seen.

For Timothy Bridges, the stakes couldn’t be much higher. Bridges was convicted and sentenced to life in prison for the beating and rape of an 83-year-old woman in Charlotte, NC, in the spring of 1989. The victim (who died of unrelated causes before Bridges trial), variously described her attacker and denied that she was raped. Ultimately, Bridges, who had wavy shoulder-length hair — which is how the victim once described her attacker — was charged with the crime. There was no DNA to connect Bridges to the crime and he was not a match for a bloody palm print found at the scene (that print was never matched to anyone). But there were two hairs collected that an FBI-trained examiner testified not only were “likely” Bridges, but also that there was a very low chance they could belong to anyone else: The “likelihood of two Caucasian individuals having indistinguishable head hair is very low,” expert Elinos Whitlock testified — the very sort of language unsupported by science and found in the faulty cases identified in the current FBI review.

Bridges appealed his conviction, arguing in part that there was no scientific basis to Whitlock’s testimony. In 1992, the state appeals court disagreed: “We find no reversible error,” the court ruled, concluding that testimony by a “properly qualified witness on hair identification” was admissible.

Bridges is currently seeking a new trial and the state is reportedly reviewing the matter.
