In the center, two cells glide along the wall in the track. The illustration at right of a circular track shows how the bacteria bind to and pull the rotor. Image credit: Yuichi Hiratsuka, et al. A new motor designed by scientists from Japan offers the best of both worlds: the living and the non-living. The group built a hybrid micromachine that is powered by gliding bacteria which travels on an inorganic silicon track and pushes a silicon dioxide rotor. The combination takes advantage of the precise engineering of synthetic devices along with the efficient energy conversion and potential for self-repair of biological systems. “Originally, we were studying the basic science of biological motors, so we routinely observed the motilities of motor proteins or bacterial or eukaryotic cells under a microscope,” said Hiratsuka. “Those graceful motilities driven by biological motors were so attractive and we started thinking of creating hybrid devices that integrate inorganic materials and biological materials. Several years ago, we succeeded in developing a system in which microtubules powered by the kinesin motor move in one direction in circular micro tracks [Ref#1 in paper]. As a natural continuation of this work, we attempted to make a micro rotary motor driven by the kinesin-microtubule system. But this turned out to be rather difficult due to technical problems. Meanwhile, we saw a presentation by Prof. (Makoto) Miyata of Osaka City Univ., who is now our close collaborator, showing a movie of mycoplasma cells gliding unidirectionally on glass surfaces. It immediately occurred to us that we should be able to make micro rotary motors if we used these bacterial cells instead of the kinesin-microtubule system.”Although Hiratsuka’s group used a slower-moving mutant strain of M. mobile for binding purposes in this study, they observed significant results on the premier run. Once the bacteria reached the circular tracks, the rotors began moving within minutes at rates of up to 2.6 rpm. Even though they could not observe the number of cells pushing the rotors in this set-up, the scientists estimated that only a few cells are needed to drive motion. Further, the team predicts that improving the directional uniformity of the bacteria, as well as increasing the sialic acid content on the track, are achievable goals that will allow more cells to drive a larger number of rotors at a higher rpm.Hiratsuka et al. also proposed in their study genetically engineering M. mobile for stronger binding to the track and rotors, as well as adding chemicals to the bacteria that urge the cells to move in a uniform direction with chemical clues. In order to avoid potential biohazards, however, the scientists also considered an interesting alternative stemming from the work of scientists Uenoyama and Miyata: M. mobile “ghosts,” which are not alive due to partial membrane dissolution, but still demonstrate gliding.Citation: Hiratsuka, Yuichi, Miyata, Makoto, Tada, Tetsuya and Uyeda, Taro Q. P. “A microrotary motor powered by bacteria.” Proceedings of the National Academy of Sciences of the United States of America. vol. 103. no. 37. 13618-13623.By Lisa Zyga, Copyright 2006 PhysOrg.com Yuichi Hiratsuka and his colleagues used a species of bacteria called Mycoplasma mobile to power their micromechanical motor. M. mobile, which has micrometer-sized cell body that glides continuously over solid surfaces, can move at speeds of up to 5 micrometers per second. Scientists aren’t sure what causes the bacteria to move, other than that several proteins are involved, but Hiratsuka’s group was still able to take advantage of the gliding ability by using entire M. mobile cells. The whole cells have been observed to work “more efficiently and intelligently” than nature’s smaller motor machines (e.g., proteins and molecules), the scientists reported.”Mycoplasma is just one example of microorganisms with interesting and potentially useful properties,” Hiratsuka told PhysOrg.com. “For instance, there is a gliding bacterium that moves using energy provided by photosynthesis. Chlamyodomonas swim toward light (phototaxis), and Dictyostelium amoeba crawl toward a specific chemical substance (chemotaxis). Though there is no way we can predict what exciting micro devices will result from these organisms, for mycoplasma, we can suggest using it as a micro pump in a microTAS. This would eliminate the need for external pumps and pipes, becoming a ‘true’ on-chip device. We might also construct electric generator systems, which convert abundant chemical energy, glucose in the body, into electric energy. In far future plans, we would like to make micro-robots driven by biological motors, which could move around and do mechanical work in the micrometer world.” The mycoplasma-driven motor consists of a square central basin where the M. mobile are deposited. As the pear-shaped cells glide throughout the square, they eventually reach a side and move along it until approaching an entrance to one of four circular tracks. The entrance ways ensure that a majority of bacteria glide in the same direction around the tracks, which are each fitted with rotors that have protrusions in the track to allow the bacteria to bind to and pull the rotors (see figure).Although an efficiently simple design, the tiny size of the motor (e.g., each rotor is 20 micrometers in diameter) required special fabrication techniques. M. mobile cells require sialic proteins (in this case, fetuin was used) to glide over solid surfaces. The scientists created a top layer of gold on the silicon track, and then deposited the sialic-acid-containing fetuin on selected lithographic micropatterns to compel the desired movement of the bacteria.

first_img The Downadup uses a complicated algorithm which changes daily and is based on timestamps from public websites such as Google.com and Baidu.com. The worm then generates many possible domain names every day.Names such as: qimkwaify .ws, mphtfrxs .net, gxjofpj .ws, imctaef .cc, and hcweu .org. It would be impossible to shut them all down because there’s just too many and most of them aren’t even registered. The bad guys running the show only need to register one domain for the day, register it, and set up a website. From there they can gain access to all of the infected machines.In order for the F-Secure Response Team to determine just how many machines are infected, they will register some of the possible domains and connect to the infected machines. Right now the Response Team is seeing hundreds of thousands of unique IP addresses connecting to the domains they have registered. A large portion of that traffic is coming from corporate networks, through firewalls, proxies, and NAT routers. This clearly shows that one unique IP address can be connected to thousands of corporate machines. All this could have been avoided if more users had patched the vulnerability in how Windows processes remote procedure call (RPC) requests by the Windows Server service.

So, do not try this one at home unless you are willing to connect your iPhone to a PC every time you want to be able to turn it on. On the bright side, this break will work on the final version of the device so if you choose to do this you will be able to jailbreak on the day of release. iPhone running on iOS 5 will be released in fall of this year. (PhysOrg.com) — The beta version of iOS has already been jailbroken, which is interesting when you consider that the iOS 5 was only announced 24 hours prior to the jailbreak, at the Apple keynote address at WWDC. The presentation, which was not devoted exclusively to the iOS 5, did detail some new features that users of the unbroken OS can expect to be able to use. last_img read more

first_img More information: A Fully Size-Resolved Perspective on the Crystallization of Water Clusters, Science, 21 September 2012: Vol. 337 no. 6101 pp. 1529-1532. DOI: 10.1126/science.1225468ABSTRACTThe number of water molecules needed to form the smallest ice crystals has proven challenging to pinpoint experimentally. This information would help to better understand the hydrogen-bonding interactions that account for the macroscopic properties of water. Here, we report infrared (IR) spectra of precisely size-selected (H2O)n clusters, with n ranging from 85 to 475; sodium doping and associated IR excitation–modulated photoionization spectroscopy allowed the study of this previously intractable size domain. Spectral features indicating the onset of crystallization are first observed for n = 275 ± 25; for n = 475 ± 25, the well-known band of crystalline ice around 3200 cm−1 dominates the OH-stretching region. The applied method has the potential to push size-resolved IR spectroscopy of neutral clusters more broadly to the 100- to 1000-molecule range, in which many solvents start to manifest condensed phase properties. Explore further (Phys.org)—It would seem that figuring out how many molecules of water are needed to form the smallest, or most basic ice crystal would have been discovered long ago, but that is not the case, because to measure both the size and structure of a water molecule cluster at the same time, two types of devices must be used, which up till now meant one disturbing the other, ruining the results. Now a group of chemists working at the Max Planck Institute has discovered a way around that problem and report that the minimum number of water molecules necessary to form an ice crystal is 275. In their paper published in the journal Science, the team describes the process they developed and how they obtained their results. Citation: Chemists find smallest number of water molecules needed to form an ice crystal (2012, September 21) retrieved 18 August 2019 from https://phys.org/news/2012-09-chemists-smallest-molecules-ice-crystal.html Finding may end a 30-year scientific debate Journal information: Sciencecenter_img Illustration of the emergence of the crystalline core in clusters containing more than 123 water molecules. The pictures of 293 and 600 water molecules show central slices of the clusters. Credit: Victoria Buch, Cristoph Pradzynski and Udo Buck © 2012 Phys.org To find out the lowest number of water molecules needed to form an ice crystal, a means of detecting water molecule clusters and how many molecules are in them must be used as well as a means of determining if that cluster is a crystal structure. To measure the first, researchers use mass spectrometry. To determine the second, infrared spectroscopy is used because the frequencies that are absorbed by chemical bonds that occur in regular water clusters are slightly different than those absorbed by ice crystals.To allow for both tests to be made at the same time, the team got around the problem of interference by doping just the surface of the water molecule clusters with sodium atoms. This allowed for mass spectrometry measurements of the cluster without disturbing its structure which meant that the team could also determine if the structure was a crystal using infrared spectroscopy.To find the smallest possible ice crystal was then a matter of brute force. The team measured water cluster sizes that ranged from 85 to 475 molecules and found that crystallization consistently occurred only after there were at least 275 molecules involved.The team suggests that smaller ice crystals cannot form due to their not being enough space after starting from a base around a center ring made of just six water molecules which are hydrogen bonded. They also suggest their method could also be used to study the crystal structure (and the way they grow) of other materials as well. This document is subject to copyright.

Journal information: Nanotechnology More information: Jianling Meng, et al. “Nanographene charge trapping memory with a large memory window.” Nanotechnology. DOI: 10.1088/0957-4484/26/45/455704 © 2015 Phys.org Graphene quantum dot flash memories look promising for data storage Citation: Nanographene charge trapping memory could further miniaturize flash (2015, November 5) retrieved 18 August 2019 from https://phys.org/news/2015-11-nanographene-memory-miniaturize.htmlcenter_img (Phys.org)—Flash memory—the data storage method often used in phones, computers, and other devices—is continually being miniaturized in order to improve device performance. In an attempt to reduce the short-circuiting that often occurs as memory cells become smaller and more closely packed, researchers have been investigating graphene-based charge trapping memory as an alternative to the traditional floating gate memory. Now in a new paper, researchers have developed a nanographene-based charge trapping memory that exhibits some of the best performance statistics for any such device reported to date. The researchers, led by Dongxia Shi and Guangyu Zhang at the Chinese Academy of Sciences in Beijing (Zhang is also with the Collaborative Innovation Center of Quantum Matter in Beijing), have published a paper on the new memory device in a recent issue of Nanotechnology.”As we all know, we are in an era of information explosion,” Jianling Meng, from the Chinese Academy of Sciences and first author of the paper, told Phys.org. “To improve data storage, it is necessary to decrease the footprint of a single node in order to achieve a high density of data storage. Thus, it is a research hot point to keep shrinking flash memories. The biggest advantage for phones and computers having smaller flash memories is a larger storage capacity. Also, smaller flash memories can improve the program/erase speed of the data.”In general, shrinking the conventional floating gate memory cell is problematic because it causes short circuits. This happens because the floating gates where the electrons are stored are conductors, and so electrons can easily flow between them when the tiny cells are too close together. An advantage of charge trapping memory is that the charge trapping layer where the electrons are stored is an insulator, so shrinking these cells does not cause short circuits nearly to the extent that it does in floating gate memory cells.In a charge trapping memory, electrons and other charge carriers are stored (or “trapped”) in tiny defects in the graphene, which the researchers call “nanographene islands.” The more nanographene islands, the more charge that can be stored, resulting in a higher memory capacity. In the new study, the researchers developed a method for fabricating nanographene with a density estimated at more than a trillion (1012) nanographene islands per square centimeter. Their strategy uses a technique called plasma etching to create large numbers of defects as well as extended defects along the edges of the main defects. The large number of charge trapping sites provided by the defects enabled the researchers to fabricate a memory device with a very competitive memory performance. One measure of large capacitance is a large memory window, which indicates that a large number of charge carriers have been trapped. Tests here revealed that the new memory has the largest ever memory window (9 volts) reported to date for a graphene-based charge trapping memory. In addition, this large memory window was maintained even after 1,000 program/erase cycles. Overall, the researchers hope that this high-density memory will provide a path toward shrinking flash memory to even smaller scales.”Our future research plan in this area is to realize a footprint as small as the tip of an atomic force microscope,” Meng said. Explore further (Left) Atomic force microscope image of the nanographene film with a high density of nanographene islands, which provide more charge-trapping sites to increase store capacity.

Carlos Santana, the 10-time Grammy winner and guitar legend, is in Delhi with wife Cindy Blackman for a performance at the F1 Rocks. He had, earlier in Bangalore, told the press ‘in our hearts, we are all one.’ Spreading the same message of world peace at the Delhi presser, Santana said, ‘I still adhere and live by the principles of the 60’s and music for me is to bring about global peace at large.’‘What religion and politics failed to achieve, like human trafficking and child labour, we are trying to do away with by spreading the message of peace and love,’ the 65-year-old said. Also Read – ‘Playing Jojo was emotionally exhausting’‘We want to make music, heal people, honour and respect women and children so that we can stop war all over the world,’ he said.Santana, a self proclaimed hippie, said the true hippie is is an individual ‘who does not belong to a herd.’He added it is about taking a stand. ‘We, during the movement in the 60’s, clearly made a point across to the Pentagon and then President Richard Nixon that no we are not afraid to die but we won’t die to make him richer.’ Also Read – Leslie doing new comedy special with Netflix‘The youth today’, he quipped,’ ‘have other preoccupations like the stupid TV.’ He added the spirit of a hippie lies in having ‘the courage to go against the corrupt system and to agree to disagree.’Dressed in a Hawaiian printed shirt and trousers, a black hat, Santana was accompanied by his wife Cindy Blackman.About his music he said: ‘My music is 99 percent African. Like spirituality and spices are to India, rhythm is to Africa.’He added: When I play music, it’s more than Mexican or American or Cubic. It is more than a genre. It is to re-connect with your heart, something we learned from you. India, he said, is the land of spirituality, of great people like Mahatma Gandhi and Mother Teresa who taught world peace.Santana said that he is open to any collaboration with Indian artistes but the time and music has to be right. ‘I would have loved to collaborate with Ali Akbar Khan, but it didn’t happen till now’.Santana said he is in awe of Indian food. ‘I wish there was a television channel wholly dedicated to Indian cuisines.’ ‘We had masala dosa for our breakfast,’ quipped his wife Cindy. read more

Alexander HamiltonAlexander Hamilton portrait by John Trumbull, 1806.Devastatingly handsome (have you checked out a $10 bill lately?), and, according to one historian, “brimming with libido,” Alexander Hamilton was the nation’s first public figure to be embroiled in a sex scandal.Alexander Hamilton, 10 dollar bill closeupHe came clean…and then some. Instead of merely offering a mea culpa, Hamilton, in a major TMI moment, described his indiscretions in what was termed “almost picaresque detail,” making colleagues cringe.Thomas JeffersonThomas Jefferson, 1791.As a young man in college, when facing his crush, Rebecca Burwell, Thomas Jefferson said, “I was prepared to say a great deal.I had dressed up in my own mind such thoughts as occurred to me, in as moving language as I know how, and expected to have performed in a tolerably credible manner.”Statue of Thomas Jefferson inside memorial in Washington, D.C.“But, good God! when I had an opportunity of venting them, a few broken sentences, uttered in great disorder, and interrupted with pauses of uncommon length, were the too visible marks of my strange confusion.”Thomas Jefferson.Suffice to say, Jefferson shook the whole shyness thing years later, becoming quite the catch — not to mention the very definition of a Renaissance man: violinist, inventor of words (belittle, to name one), a gourmet and a wine connoisseur (during his eight years in the White House, he ran up a wine bill of about $10,000 — nearly $150,000 today!).Benjamin FranklinSure, Ben Franklin had a way with words — he published the Poor Richard’s Almanac, after all.

first_imgJune 12, 2014 This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Opinions expressed by Entrepreneur contributors are their own. Why should company owners care about creating mobile apps for their workforce that are intuitive? Because their employees do. The standards of what’s considered a well-designed mobile app have been raised and a clunky enterprise app can seriously hinder an organization’s productivity.Attitudes about enterprise mobile apps have changed, primarily because work and personal lives have become so intertwined. Today people answer business emails from the family room, review sales leads from the backyard deck and solve IT problems on their commute. Employees are constantly connected, managing their work lives around the clock. Related: Enterprise Apps Are Less Glitter but More Gold for DevelopersWith the line between professional and personal spheres blurring, expectations for app usability have changed as well. Workers are continually switching between consumer apps and business apps. The bar on ease of use has been raised because employees view all tablet and smartphone apps through the same lens. All they know is that some apps are seamless, intuitive and robust while others are not.Workers expect intuitive, easy-to-use, “consumerized” enterprise mobile apps because that’s what they are accustomed to. Anything less will result in a precipitous decrease in engagement — and productivity.Decision makers are beginning to take note of the discrepancies between consumer and business software. They are realizing that easy data entry, quick access to key functions and simple navigation are essential to smooth workflows and high productivity. Apps should be designed for business consumer, so that the user experience is seamless and even delightful within a professional context.Unfortunately, easy to use isn’t the same thing as simple to create. Many executives assume that since app stores are filled with 99-cent or even free apps, they must not be challenging to develop. But effective, intuitive and functional enterprise mobile apps are the result of sound planning and effort. Related: Tapping Into the Expanding Mobile Opportunities of Emerging MarketsUnique environment. Good enterprise mobile apps are much more than a migration of desktop enterprise software. It’s almost impossible to exactly match the features of a desktop application. The hardware environments are simply too distinct.So what constitutes a good enterprise mobile app?  Research suggests that for 80 percent of all business software applications, users engage with only four or five key functions. When creating an enterprise mobile app, the job is to identify those functions and design for them alone.For example, a mobile app for time tracking should focus on that specific process alone and align app features accordingly or employees won’t use it. It also should be easy to navigate. Users need quick access if they are going to routinely use the app to accomplish their tasks.Real estate is another critical factor. Tablet screens (typically 10 inches diagonally) and smartphone screens (4 inches to 5 inches diagonally) are smaller than laptops or desktops, so designers must be honest about how much content can be displayed. Quality mobile apps eschew a small typeface for simple graphics and limited navigational choices.While attractive graphics in a mobile app are great, it’s even more critical to tailor the graphic interface to the user’s needs.Syncplicity, a file-sharing app of EMC, provides an example of how a user interface can simplify a device’s operation. (My company Y Media Labs serves as a mobile-interactive app consultant to EMC.) Syncplicity was built with the idea that users want fast access to their files. The designers for Syncplicity knew that creating a “favorites” function wasn’t the answer: “Favorites” can change almost daily at work. Constantly marking files as “favorites” would require multiple tedious steps on a mobile device. The designers also realized that people working on a project often return to the same files and folders repeatedly. So the designers implemented a “recently accessed” option to let users quickly go to the exact information desired.Related: Outsource Your App Development Effectively With These 5 TipsTesting is essential. To create an exceptional enterprise mobile app, designers must combine beauty and brains. They must aspire to establish a visceral connection between the app and the user, one combining aesthetics with personalization. Displaying time of day upon launch (factoring in local time zones), changing backgrounds according to the time of day, noting key corporate events or news, and even greeting the individual by name (“Good morning, John Smith”) are some of the ways to make an app more enjoyable.Building a consumerized app is an evolutionary process. Testing is an immensely beneficial method for discovering users’ preferences and ensuring that they find an app easy to navigate.Functional testing using a paper prototype can weed out 80 percent to 85 percent of an app’s potential problems before the first line of code is written. Digital prototyping makes quick, effective usability testing possible. Engineers can now run tests remotely via the Internet, without test subjects being present. A large cohort isn’t necessary, since the main goal is to uncover gaps in flows or other issues. It’s important to recruit target users, however, for relevant feedback.As development progresses, additional testing will ensure no expensive mistakes are present. Unlike years ago when testing followed a huge engineering run, agile development now allows testing to occur incrementally, as often as every two weeks.Even post-release, testing has value. The focus shifts to usage metrics to uncover the screens people are spending time with and the buttons they’re clicking. Heat maps are used to determine where people are spending time and how they’re navigating. By isolating the good and bad aspects of an app in the field, designers can better plan updates — and learn what will work in other projects. Related: 6 Productivity Apps for the Entrepreneur on the Go Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Enroll Now for Free 5 min readlast_img read more

first_img Register Now » Lockheed Martin Corp said on Wednesday it had made a technological breakthrough in developing a power source based on nuclear fusion, and the first reactors, small enough to fit on the back of a truck, could be ready for use in a decade.Tom McGuire, who heads the project, said he and a small team had been working on fusion energy at Lockheed’s secretive Skunk Works for about four years, but were now going public to find potential partners in industry and government for their work.Initial work demonstrated the feasibility of building a 100-megawatt reactor measuring seven feet by 10 feet, which could fit on the back of a large truck, and is about 10 times smaller than current reactors, McGuire told reporters.In a statement, the company, the Pentagon’s largest supplier, said it would build and test a compact fusion reactor in less than a year, and build a prototype in five years.In recent years, Lockheed has gotten increasingly involved in a variety of alternate energy projects, including several ocean energy projects, as it looks to offset a decline in U.S. and European military spending.Lockheed’s work on fusion energy could help in developing new power sources amid increasing global conflicts over energy, and as projections show there will be a 40 percent to 50 percent increase in energy use over the next generation, McGuire said.If it proves feasible, Lockheed’s work would mark a key breakthrough in a field that scientists have long eyed as promising, but which has not yet yielded viable power systems. The effort seeks to harness the energy released during nuclear fusion, when atoms combine into more stable forms.”We can make a big difference on the energy front,” McGuire said, noting Lockheed’s 60 years of research on nuclear fusion as a potential energy source that is safer and more efficient than current reactors based on nuclear fission.Lockheed sees the project as part of a comprehensive approach to solving global energy and climate change problems.Compact nuclear fusion would produce far less waste than coal-powered plants since it would use deuterium-tritium fuel, which can generate nearly 10 million times more energy than the same amount of fossil fuels, the company said.Ultra-dense deuterium, an isotope of hydrogen, is found in the earth’s oceans, and tritium is made from natural lithium deposits.It said future reactors could use a different fuel and eliminate radioactive waste completely.McGuire said the company had several patents pending for the work and was looking for partners in academia, industry and among government laboratories to advance the work.Lockheed said it had shown it could complete a design, build and test it in as little as a year, which should produce an operational reactor in 10 years, McGuire said. A small reactor could power a U.S. Navy warship, and eliminate the need for other fuel sources that pose logistical challenges.U.S. submarines and aircraft carriers run on nuclear power, but they have large fission reactors on board that have to be replaced on a regular cycle.”What makes our project really interesting and feasible is that timeline as a potential solution,” McGuire said.Lockheed shares fell 0.6 percent to $175.02 amid a broad market selloff.(Editing by Jeffrey Benkoe) This story originally appeared on Reuters Growing a business sometimes requires thinking outside the box.

first_img Opinions expressed by Entrepreneur contributors are their own. 6 min read Listen Now September 6, 2017 How Success Happens Hear from Polar Explorers, ultra marathoners, authors, artists and a range of other unique personalities to better understand the traits that make excellence possible. Companies deal with a variety of risks to their business operations every single day, but there is a new threat originating in the Dark Web that they cannot afford to overlook: “crime-as-a-service,” or CaaS.Crime-as-a-service is when a professional criminal or group of criminals develop advanced tools, “kits” and other packaged services which are then offered up for sale or rent to other criminals who are usually less experienced. This is having a powerful effect on the world of crime — and cybercrime in particular — because it lowers the bar for inexperienced actors to launch sophisticated cyber attacks and scams. In 2017, Europol released a new study that flagged CaaS as a major facilitator of serious online crimes, as well as traditional crimes like illegal weapons sales.Related: Cybercriminals Are Targeting Small Businesses That Don’t Take Cybersecurity SeriouslyThis evolution in the world of cybercrime also coincides with a shift in the types of businesses that are being targeted. When people think of data breaches, they usually think of big corporate victims like Yahoo, Target and Home Depot. However, the reality is that cybercriminals are increasingly targeting small businesses over enterprises, because an small businesscan’t afford to spend what a large corporation does on cybersecurity.According to a 2016 study by the Ponemon Institute, half of all small businesses in the U.S. have been breached by hackers. They are also the top target for “spear-phishing,” or targeted fake email attacks, which have more than doubled since 2011. CaaS is a major contributing factor to the rise of these attacks on small businesses.It’s important to understand that crime-as-a-service is not some minor new trend in hacking. It is a game changer, particularly for small businesses. Because of CaaS, future online attacks will be harder to detect, harder to prevent, there will be far more of them and they will be considerably more expensive to clean up than they have been in years past.Here are five popular CaaS offerings on the Dark Web that are most likely to impact small businesses:1. Phishing kitsEmail attacks consistently rank at the top of the list when it comes to small business cyber threats. It used to be fairly easy to spot a fake email, as these scams were often riddled with spelling mistakes and bad English. Today, however, that is no longer the case. Professional “phishing kits” are now available online which are very good at helping criminals impersonate legitimate organizations like banks and the IRS. These kits may come with pre-written form letters which imitate the language, format and logos of real organizations; fake web pages to solicit the victim’s information; “crimeware” that automates the theft of online credentials; spamming software and more.Security tip: Use a malware detection service with anti-phishing support and consider “whitelisting” key operators in the company so they will only receive email from approved contacts. Security awareness training is also important.Related: What Small Business Owners Need to Know About Cybersecurity2. Exploit kitsThere are an abundance of software vulnerabilities out in the wild, but it takes skill to use them. For this reason, professional hackers sell “exploit kits” online (such as RIG, Neutrino and Sundown/Nebula) that incorporate these vulnerabilities into a ready-made hacking tool or set of tools that make it easier for a criminal to break into a company’s network and/or infect it with malware.Security tip: Make sure all software is updated regularly. Additionally, check the company’s website and network using a vulnerability scanning service.3. MalwareWorms, Trojans and viruses are the crown jewel of any attacker’s toolkit. But, developing “good” malware requires solid expertise, which not many cybercriminals have. Today, however, anyone can go onto the Dark Web and buy malware and malware kits, which they can use as-is or customize for specific targets. These online offerings even come with antivirus evasion (i.e., they hide or alter the malware’s “signature” in order to prevent detection by an AV product) and customer support. Ransomware is extremely popular today, but there are plenty of other dangerous products up for sale, including banking Trojans, remote access Trojans (RATs), keyloggers and mobile malware.Security tip: Assume your business will get infected with malware and plan accordingly. Have an outbound firewall in place to prevent malware from “phoning home” to the attacker. Segregate the network so malware can’t spread easily. Backup data regularly in case of loss. Use two-factor authentication for all online accounts.Related: What Businesses Can Do About a Trillion-Dollar Fraud Problem4. Criminal phone banksAs the name implies, this is a service in which criminals have created their own call center operation that can be rented out to other criminals. These are usually operated over VoIP lines in order to conceal their true location and make it easier to spoof phone numbers and impersonate legitimate organizations. They may even use “soundtracks” to imitate the background noises of a busy call center or office, and provide operators with specific accents. A criminal might rent a call center to support a phishing email campaign (“Call this number for assistance with your IRS claim”), or to social engineer an office employee or impersonate a company official to fool a bank.Security tip: Establish clear policies for employees about sharing sensitive information via phone, especially with respect to financial transactions.5. DDoS-for-hireDistributed denial-of-service (DDoS) attacks can be crippling to any business, as they can knock out websites, customer portals, email service and network connectivity. In the past few years, they have also become exponentially more powerful, due to methods like DNS amplification and NTP amplification attacks. It’s estimated that 73 percent of global brands and organizations are hit by DDoS attacks every year, and many are the victims of repeated attacks. Criminals used to have to build up their own “botnet” containing thousands of infected computers in order to launch these attacks, but now all they have to do is rent a botnet service online.Security tip: Consider hiring a DDoS mitigation service to protect your website.The importance of planning aheadCrime-as-a-service will increase the risks of financial fraud, cyber extortion and data theft for all types of businesses, but smaller companies are at the greatest risk. For this reason, it is essential for business owners to create a “defense in depth” approach that focuses equally on preventive security and post-breach containment. The latter is especially important because no business will be able to prevent every cyber attack. By planning ahead for a network breach, the company can minimize the damage.last_img read more
