A little more than five years ago, a previously unused Reddit account began posting seemingly random strings of numbers and text in a new subreddit it had created. To the casual eye, there wasn’t much to see. The subreddit shared the same inscrutable set of numbers and letters as its moderator; the sidebar and comments provided no clarifying information.
After a long wait, Set 8 of the Cryptopals Crypto Challenges has been announced. Designed to be approachable by neophytes and newbies, one Hacker News commenter describes them as "...a much more interesting version of those silly string manipulation tasks you get in CS101, except that instead of passing a course you break harder and harder crypto." Filippo Valsorda, a very well-known and respected cryptographer has announced that he will be doing a live speedrun of the challenges on Twitch.
So what are the chances of encryption technologies being viewed as a "bearable arm" under the Second Amendment?

“I think the post-war turn towards social responsibility in science and engineering was less a turn than a sideways glance. ..

Once again, the ability of ordinary people to use strong encryption is under threat from lawmakers. In the wake of the exposure of the Five Eyes spying dragnet, consumers have demanded encryption, while the FBI claims encrypted devices will prevent it from fighting crime (or will they?) While the FBI has its own solution, experts deride it as impossible. Meanwhile, online mercenaries sell spyware to anyone who will pay them.

The radio signal that occupies 4625 kHz has reportedly been broadcasting since the late 1970s. The earliest known recording of it is dated 1982. Ever since curious owners of shortwave radios first discovered the signal, it has broadcast a repeating buzzing noise. Every few years, the buzzer stops, and a Russian voice reads a mixture of numbers and Russian names.

Washington Post: Technology companies are scrambling to fix a major security flaw that for more than a decade left users of Apple and Google devices vulnerable to hacking when they visited millions of supposedly secure Web sites, including Whitehouse.gov, NSA.gov and FBI.gov. The flaw resulted from a former U.S. government policy that forbade the export of strong encryption and required that weaker “export-grade” products be shipped to customers in other countries, say the researchers who discovered the problem. These restrictions were lifted in the late 1990s, but the weaker encryption got baked into widely used software that proliferated around the world and back into the United States, apparently unnoticed until this year.

He was sitting on his bed, surreptitiously surfing the science and math board on 4chan, the notorious underground forum, when he came across a strange image that had appeared on the site three days earlier. It contained a message written in a thin white font against a black background. "Hello," it read. "We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck." It was signed "3301." [more inside]

If your cryptography predates The Fresh Prince, you need better cryptography. With recognition of the need for secure communication standards finally going mainstream, crypto researcher and Johns Hopkins University professor Matthew Green takes a hard look at the de facto standard everyone is jumping on, and suggests that we can and should do a lot better.

"Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract. Although that sum might seem paltry, it represented more than a third of the revenue that the relevant division at RSA had taken in during the entire previous year, securities filings show." Previous
On January 5th 2012, an image was uploaded to various image boards. It contained two messages. One was obvious & easy to read. In white letters on a black background it said:
Hello. We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck. 3301As promised there was another message hidden inside the image. It was the start of a bizarre, as yet unexplained chain of complex hidden messages leading those who could solve them on a journey across the Internet and around the world towards a destination none of them could predict with certainty. Is it a highly evolved ARG? Is it a recruitment campaign for the NSA? Welcome to the mystery of Cicada 3301.

In a crackdown that FBI claims to be about hunting down pedophiles, half of the onion sites in the TOR network has been compromised, including the e-mail counterpart of TOR deep web, TORmail.

Enigma breaker Alan Turing will be posthumously pardoned. Turing helped the Allies win WWII by developing the methods that broke the German Enigma code -- which didn't stop Britain from convicting him of gross indecency under anti-homosexuality legislation in 1951 and subjecting him to chemical castration. Two years later, he committed suicide by swallowing cianide. The British government has now "signalled that it is prepared to support a backbench bill that would pardon Turing."

An advanced and well-orchestrated computer spy operation that targeted diplomats, governments and research institutions for at least five years has been uncovered by security researchers in Russia.
The highly targeted campaign, which focuses primarily on victims in Eastern Europe and Central Asia based on existing data, is still live, harvesting documents and data from computers, smartphones and removable storage devices, such as USB sticks, according to Kaspersky Lab, the Moscow-based antivirus firm that uncovered the campaign. Kaspersky has dubbed the operation “Red October.”[more inside]

Bitcoin is growing up: early adopters lost money due to bad backups; the US Senate wants to crack down due to possible illegal drug purchases with the digital coins; it had its Black Friday, losing 30% of its value in one day (after a 5,600% increase in the first year); the Economist weighs in; and now an alledged heist of 25k bitcoins (original forum post), valued between $250k and $750k on the Mt. Gox exchange. Currently 154 petaflops of CPU and GPUs are computing SHA256 hashes in tight loops, easily beating the #1 on the top500, the Tiahne-1A with 2.56 petaflops.

Bitcoin is a peer-to-peer digital currency. Trading at eight dollars this week—and being used to pay for everything from freelance programming jobs to magic mushrooms—it has been described as “the most dangerous open-source project ever created” and “an unambiguous challenge to the government monopoly on the power to print money.” Estimated at over 20 petaFLOPS the Bitcoin network is currently the fastest virtual supercomputer in the world.

On June 30, 1999, sheriff’s officers in St. Louis, Missouri discovered the body of 41-year-old Ricky McCormick. He had been murdered and dumped in a field. The only clues regarding the homicide were two encrypted notes found in the victim’s pants pockets. The FBI is now asking the public to help them solve the murder.
How To Make Anything Signify Anything "By the time he retired from the National Security Agency in 1955, Friedman had served for more than thirty years as his government’s chief cryptographer, and—as leader of the team that broke the Japanese PURPLE code in World War II, co-inventor of the US Army’s best cipher machine, author of the papers that gave the field its mathematical foundations, and coiner of the very term cryptanalysis—he had arguably become the most important code-breaker in modern history."

Thomas Jefferson's cipher message from Robert Patterson For more than 200 years, buried deep within Thomas Jefferson's correspondence and papers, there lay a mysterious cipher -- a coded message that appears to have remained unsolved. Until now.... To Mr. Patterson's view, a perfect code had four properties: It should be adaptable to all languages; it should be simple to learn and memorize; it should be easy to write and to read; and most important of all, "it should be absolutely inscrutable to all unacquainted with the particular key or secret for decyphering."
