Strange galaxy is made almost entirely of dark matter

A galaxy isn’t big just because it has many stars in it. A worldwide research group has discovered that a galaxy in the Coma cluster, Dragonfly 44, consists of 99.99 percent dark matter . It has about as much mass as our own Milky Way galaxy, but far fewer stars. The team determined the presence of the invisible, mysterious substance based on the motions of the stars themselves — there were too few of them to be moving so quickly. If there weren’t a gravitational force like dark matter to hold them together, those stars would simply fly away. Dragonfly 44 raises more questions than it solves right now. The team’s Roberto Abraham tells Wired that it’s unclear as to how a dark matter galaxy on this scale could form. Previous examples were much smaller. It’s possible that the formations of the stars (very dense clusters) are a clue, but that’s as far as astronomers can go right now. The hope is that someone will find a similar galaxy closer to home, increasing the chances of finding a dark matter particle and making some sense out a baffling (but virtually ubiquitous) aspect of the universe.

Linux Trojan Mines For Cryptocurrency Using Misconfigured Redis Servers

An anonymous reader writes: In another installment of “Linux has malware too, ” security researchers have discovered a new trojan that targets Linux servers running Redis, where the trojan installs a cryptocurrency miner. The odd fact about this trojan is that it includes a wormable feature that allows it to spread on its own. The trojan, named Linux.Lady, will look for Redis servers that don’t have an admin account password, access the database, and then download itself on the new target. The trojan mines for the Monero crypto-currency, the same one used by another worm called PhotoMiner, which targets vulnerable FTP servers. According to a recent Risk Based Security report from last month, there are over 30, 000 Redis servers available online without a password, of which 6, 000 have already been compromised by various threat actors.

Facebook Will Force Advertising On Ad-Blocking Users

Long-time reader geek writes: Facebook is going to start forcing ads to appear for all users of its desktop website, even if they use ad-blocking software (Could be paywalled; alternate source). The social network said on Tuesday that it will change the way advertising is loaded into its desktop website to make its ad units considerably more difficult for ad blockers to detect. “Facebook is ad-supported. Ads are a part of the Facebook experience; they’re not a tack on, ” said Andrew “Boz” Bosworth, Facebook’s vice president of engineering for advertising and pages.

London’s Metropolitan Police Still Running 27,000 Windows XP Desktops

An anonymous reader writes: London’s Met Police has missed its deadline for abandoning the out-of-date operating system Windows XP, as findings reveal 27, 000 computers still run on the software two years after official support ended. Microsoft stopped issuing updates and patches for Windows XP in Spring 2014, meaning that any new bugs and flaws in the operating system are left open to attack. A particularly risky status for the UK capital’s police force – itself running operations against hacking and other cybercrime activity. The figures were disclosed by Conservative politician Andrew Boff. The Greater London Assembly member said: ‘The Met should have stopped using Windows XP in 2014 when extended support ended, and to hear that 27, 000 computers are still using it is worrying.’ As in similar cases across civil departments, the core problem is bespoke system development, and the costs and time associated with integrating a new OS with customized systems.

Nigerian Scammers Infect Themselves With Own Malware, Reveal New Fraud Scheme

“A pair of security researchers recently uncovered a Nigerian scammer ring that they say operates a new kind of attack…after a few of its members accidentally infected themselves with their own malware, ” reports IEEE Spectrum. “Over the past several months, they’ve watched from a virtual front row seat as members used this technique to steal hundreds of thousands of dollars from small and medium-sized businesses worldwide.” Wave723 writes: Nigerian scammers are becoming more sophisticated, moving on from former ‘spoofing’ attacks in which they impersonated a CEO’s email from an external account. Now, they’ve begun to infiltrate employee email accounts to monitor financial transactions and slip in their own routing and account info…The researchers estimate this particular ring of criminals earns about US $3 million from the scheme. After they infected their own system, the scammers’ malware uploaded screenshots and all of their keystrokes to an open web database, including their training sessions for future scammers and the re-routing of a $400, 000 payment. Yet the scammers actually “appear to be ‘family men’ in their late 20s to 40s who are well-respected, church-going figures in their communities, ” according to the article. SecureWorks malware researcher Joe Stewart says the scammers are “increasing the economic potential of the region they’re living in by doing this, and I think they feel somewhat of a duty to do this.” Read more of this story at Slashdot.

Olympic Swimmers ‘Certain’ To Pick Up Virus From Three Teaspoons of Rio Water

An anonymous reader writes from a report via The Independent: The Associated Press has released a 16-month-long study that shows just days before the Olympic Games in Rio de Janeiro begin, the waterways in the city are teeming with dangerous viruses and bacteria. The report says both athletes and tourists are at risk of getting ill from the contaminated water. “The first results of the study published over a year ago showed viral levels at up to 1.7 million times what would be considered worrisome in the United States or Europe, ” reports The Independent. “At those concentrations, swimmers and athletes who ingest just three teaspoons of water are almost certain to be infected with viruses that can cause stomach and respiratory illnesses and, more rarely, heart and brain inflammation — although whether they actually fall ill depends on a series of factors including the strength of the individual’s immune system.” Many of the athletes have been taking antibiotics, bleaching oars and donning plastic suits and gloves to prevent illnesses, but antibiotics combat bacterial infections, not viruses. The AP investigation found that infectious adenovirus readings turned up at nearly 90 percent of the test sites over 16 months of testing. What’s more is that “the beaches often have levels of bacterial markers for sewage pollution that would be cause for concern abroad — and sometimes even exceed Rio state’s lax water safety standards, ” reports The Independent.

You can cut this display with scissors

Want a display that can take any shape ? You might not need a factory to cut it for you in the future — may only need a pair of scissors and a steady hand. Japan’s National Institute for Materials Science has developed a flexible, organic/metal hybrid polymer display that you can cut without wrecking it. The technology only needs a few seconds of power to adjust to its new shape, and it even maintains its last information when you switch it off, a lot like e-paper. The existing design only displays in one color and has a limited display area. It’s easy to see the practical purposes even now, though. You could make your own clothes with integrated displays, or craft smart wearables that fit the exact shape of your wrist. The researchers also envision a world where you could change the colors of car interiors, sunglasses and windows thanks to displays that fit just about anything. Any such breakthrough is undoubtedly years away, but the very fact that it’s a possibility is noteworthy. Via: Science News Journal Source: NIMS

Malvertising Campaign Infected Thousands of Users Per Day For More Than a Year

An anonymous reader writes from a report via Softpedia: Since the summer of 2015, users that surfed 113 major, legitimate websites were subjected to one of the most advanced malvertising campaigns ever discovered, with signs that this might have actually been happening since 2013. Infecting a whopping 22 advertising platforms, the criminal gang behind this campaign used complicated traffic filtering systems to select users ripe for infection, usually with banking trojans. The campaign constantly pulled between 1 and 5 million users per day, infecting thousands, and netting the crooks millions each month. The malicious ads, according to this list, were shown on sites like The New York Times, Le Figaro, The Verge, PCMag, IBTimes, Ars Technica, Daily Mail, Telegraaf, La Gazetta dello Sport, CBS Sports, Top Gear, Urban Dictionary, Playboy, Answers.com, Sky.com, and more.
