Submission + - First victim of SHA-1 collisions: Subversion. Technique was reverse engineered

Artem Tashkinov writes: A WebKit developer who tried to upload "bad" PDF files generated from the first successful SHA-1 attack broke WebKit's SVN repository because Subversion uses SHA-1 hash to differentiate commits. The reason to upload the files was to create a test for checking cache poisoning in WebKit.

Another news story is that based on the theoretical incomplete description of the SHA-1 collision attack published by Google just two days ago, people have managed to recreate the attack in practice and now you can download a python script which can create a new PDF file with the same SHA-1 hashsum using your input PDF. The attack is also implemented as a website which can prepare two PDF files with different JPEG images which will result in the same hash sum.

Submission + - White House blocks news organizations from press briefing (cnn.com)

ClickOnThis writes: CNN reports that it, along with several other major news organizations, were blocked from attending a press briefing at the White House today. From the article:

The New York Times, the Los Angeles Times, Politico and BuzzFeed were also excluded from the meeting, which is known as a gaggle and is less formal than the televised Q-and-A session in the White House briefing room. The gaggle was held by White House press secretary Sean Spicer.

In a brief statement defending the move, administration spokeswoman Sarah Sanders said the White House "had the pool there so everyone would be represented and get an update from us today."

The pool usually includes a representative from one television network and one print outlet. In this case, four of the five major television networks — NBC, ABC, CBS and Fox News — were invited and attended the meeting, while only CNN was blocked.

And while The New York Times was kept out, conservative media organizations Breitbart News, The Washington Times and One America News Network were also allowed in.


Submission + - Malaysian Police: VX nerve gas killed N Korea leader's brother in airport attack (reuters.com)

An anonymous reader writes: Malaysian police have announced their finding that Kim Jong Nam, half-brother of North Korean leader Kim Jon Un, was killed by assassins using VX nerve gas in an attack in the busy Kuala Lumpur airport. Malaysian authorities plan to decontaminate the airport and other sites visited by the attackers. Police are holding the two female attackers, one of whom was affected by the chemical agent, as well as two other men. They are seeking seven more North Koreans connected to the case. VX is the most toxic of the nerve gasses and the UN has declared it a weapon of mass destruction. The manufacture and stockpiling of more than 100 grams of VX per year is prohibited by the Chemical Weapons Convention of 1993. It has no commercial uses. The Malaysian police are trying to discover if it was smuggled into their country, or manufactured there. The Malaysian government has recalled its ambassador to North Korea for consultation. North Korea is blaming the death of Kim Jong Nam on Malaysia. North Korea is believed to have major stockpiles of chemical weapons, and is alleged to conduct experiments on prisoners and social undesirables.

Submission + - SPAM: UV-Illuminated Rhodium: Plentiful Methane from Carbon Dioxide

Freshly Exhumed writes: Researchers in the Chemistry and Physics Departments at Duke University have found that CH4 (Methane) is almost exclusively produced when rhodium nanoparticles are mildly illuminated in ultraviolet LED light, yielding a seven-fold increase in the CH4 production rate over dark conditions, while only a slight increase in simultaneous CO production was detected. No other carbon-containing product was observed, making this photocatalytic process an enticing possible solution for the reduction of carbon dioxide concentrations in the atmosphere while simultaneously producing methane for fuel and industrial use. Rhodium is commonly used in automobile catalytic converters.

Submission + - The race for autonomous cars is over. Silicon Valley lost. (autoblog.com)

schwit1 writes: Up until very recently the talk in Silicon Valley was about how the tech industry was going to broom Detroit into the dustbin of history. Companies such as Apple, Google, and Uber — so the thinking went -were going to out run, out gun, and out innovate the automakers. Today that talk is starting to fade. There's a dawning realization that maybe there's a good reason why the traditional car companies have been around for more than a century.

Last year Apple laid off most of the engineers it hired to design its own car. Google (now Waymo) stopped talking about making its own car. And Uber, despite its sky high market valuation, is still a long, long way from ever making any money, much less making its own autonomous cars.

To paraphrase Elon Musk, Silicon Valley is learning that "Making rockets is hard, but making cars is really hard." People outside of the auto industry tend to have a shallow understanding of how complex the business really is. They think all you have to do is design a car and start making it. But most startups never make it past the concept car stage because the move to mass production proves too daunting.

So apparently an ISP being able to tell people up front what their fees and charges will be is a

burdensome requirements [...] that impose serious and unnecessary costs

I guess this explains why big ISPs like Comcast and such manage to fuck up billing people on a regular basis. It's just too goddamn hard for companies to know what they charge for their services.

Submission + - Study Reveals Bot-On-Bot Editing Wars Raging On Wikipedia's Pages (theguardian.com)

An anonymous reader writes: A new study from computer scientists has found that the online encyclopedia is a battleground where silent wars have raged for years. Since Wikipedia launched in 2001, its millions of articles have been ranged over by software robots, or simply “bots," that are built to mend errors, add links to other pages, and perform other basic housekeeping tasks. In the early days, the bots were so rare they worked in isolation. But over time, the number deployed on the encyclopedia exploded with unexpected consequences. The more the bots came into contact with one another, the more they became locked in combat, undoing each other’s edits and changing the links they had added to other pages. Some conflicts only ended when one or other bot was taken out of action. The findings emerged from a study that looked at bot-on-bot conflict in the first ten years of Wikipedia’s existence. The researchers at Oxford and the Alan Turing Institute in London examined the editing histories of pages in 13 different language editions and recorded when bots undid other bots’ changes. While some conflicts mirrored those found in society, such as the best names to use for contested territories, others were more intriguing. Describing their research in a paper entitled Even Good Bots Fight in the journal Plos One, the scientists reveal that among the most contested articles were pages on former president of Pakistan Pervez Musharraf, the Arabic language, Niels Bohr and Arnold Schwarzenegger. One of the most intense battles played out between Xqbot and Darknessbot which fought over 3,629 different articles between 2009 and 2010. Over the period, Xqbot undid more than 2,000 edits made by Darknessbot, with Darknessbot retaliating by undoing more than 1,700 of Xqbot’s changes. The two clashed over pages on all sorts of topics, from Alexander of Greece and Banqiao district in Taiwan to Aston Villa football club.

Submission + - Autism Risk Linked to Herpes Infection During Pregnancy (neurosciencenews.com)

baalcat writes: Women with signs of active genital herpes had twice the odds of giving birth to offspring with autism spectrum disorder.

Women actively infected with genital herpes during early pregnancy had twice the odds of giving birth to a child later diagnosed with autism spectrum disorder (ASD), according to a study by scientists at the Center for Infection and Immunity at Columbia University’s Mailman School of Public Health and the Norwegian Institute of Public Health.

The study is the first to provide immunological evidence on the role of gestational infection in autism, reporting an association between maternal anti-herpes simplex virus-2 (HSV-2) antibodies and risk for ASD in offspring. Results appear in mSphere, a journal of the American Society for Microbiology.

Submission + - A.T.F. Filled Secret Bank Account With Millions From Shadowy Cigarette Sales (nytimes.com)

schwit1 writes: “Working from an office suite behind a Burger King in southern Virginia, operatives used a web of shadowy cigarette sales to funnel tens of millions of dollars into a secret bank account. They weren’t known smugglers, but rather agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives. The operation, not authorized under Justice Department rules, gave agents an off-the-books way to finance undercover investigations and pay informants without the usual cumbersome paperwork and close oversight, according to court records and people close to the operation.”

Laws and rules are for the little people.
