Today brings good news: Grum, a botnet responsible for 18% of all spam, is no more. Here’s how a team of crack cybersleuths took down the world’s third-largest spammer.The search-and-destroy stories that surface when a spam botnet is taken down are some of the juiciest to be found in any medium. Botnet takedowns have all the elements of a great plot: a global villain, exotic locales, despicable offenses, dedicated heroes who strive for the good of humanity, and a mystery that takes many steps to uncover. It is “Dick Tracy” meets “Hackers.”Grum was a devious mist of a network with no obvious central structure. The face of a botnet like Grum is a distributed sub-network of command-and-control (CnC) servers. These machines direct an army of zombie underlings, ordinary personal computers that have been infected with malware that takes orders from CnC to churn out spam. Grum marshaled at least 120,000 spam-spewing zombies, according to Spamhaus. The actual number of zombies in the network could have been a lot more.Grum has been in existence for at least four years, an impressive lifespan for a botnet, according to Atif Mushtaq, senior staff scientist at security company FireEye. Mushtaq, along with Carel van Straten and Thomas Morrison from Spamhaus and Alex Kuzmin from CERT-GIB, tracked down the botnet. An anonymous security researcher who goes by the name Nova7 also helped track down the spammers. Their mission was to discover the CnC servers and systematically take them offline. By tracking IP addresses, FireEye and other researchers were able to track Grum to a central CnC location in the Netherlands. The team sent abuse notifications to the Dutch authorities telling them to cut off access to the servers through its Internet Service Provider (ISP). Authorities in the Netherlands acted fairly quickly and Grum’s primary hub was taken down.But Grum was not so easily stopped. Like Hercules battling the Lernaean Hydra, the team cut off one head only to watch two grow in its place. Its Dutch head having been decapitated, the botnet moved its resources to secondary servers in Panama and Ukraine. These servers were more difficult to deal with because ISPs in those countries often look the other way, making them notorious safe havens for botnets. “Shutting down any servers there has never been easy,” Mushtaq said.The sleuths applied pressure until the ISP hosting Grum in Panama shut off access to the botnet. It was a big success for the research team, but the battle was not yet over. “After seeing the Panamanian server had been shut down, the bot herders moved quickly and started pointing the rest of the CnCs to new secondary servers in Ukraine,” Mushtaq wrote. “I was thinking that all we needed was to take down one Russian server, but right in front of my eyes, the bot herders started pointing their botnet to new destinations. I must say, for a moment, I was stunned. The bot herders replaced the two Dutch servers with six new servers located in Ukraine.”Mushtaq passed this information to the other researchers who then pressured their contacts in Ukraine and Russia to take down these servers. By 11:00 a.m. PST on July 18th, the servers had been taken offline and the battle to destroy Grum was won.The Battle Against BotnetsFor a long while, the primary agents against botnets were governments. These entities could use their power to force ISPs to sever access to CnCs that control the zombie armies. But governments are often not well equipped to do so. Moreover, they act slowly and do not always prioritize campaigns against botnets.That has changed. In the last several years, the fighting of botnets has become a private-sector effort, with researchers such as those at FireEye leading the charge. Microsoft has also entered the fray. In July 2011, Microsoft offered $250,000 for information leading to the capture and conviction of the individuals responsible for Rustock. This makes sense: Microsoft’s Windows operating system is the most installed computer software in the world. Malicious hackers who launch botnet malware have historically focused on Windows for this reason. It behooves Microsoft to be as proactive as possible in helping track down the people responsible.“Traditionally, government entities monitored and pursued these entities,” said Kapil Raina of cloud security company Zscaler, “but now we are starting to see a dramatic shift in the private-sector community directly getting involved to protect end users. In the short term, this will be very beneficial for consumers, but longer-term implications of legal policy and enforcement have yet to be sorted out.”With the destruction of Grum, the globe will see an immediate drop in spam. How long that lasts will depend on how diligently the private security community presses its offensive against botnets.last_img read more

5G is Coming — Here’s How Entrepreneurs Can Leverage It

first_imgFollow the Puck What it Takes to Build a Highly Secure FinTech … Related Posts Tags:#5G#Entrepreneurs Trends Driving the Loyalty Marketing Industry Marc Fischer is the CEO and co-founder of Dogtown Media, a mobile technology studio based in Venice Beach, California, that was named by Inc. as one of the fastest-growing companies in America. Sprint’s recent launch of its 5G network in Kansas City, Missouri; Dallas; Houston; and Atlanta offers consumers and entrepreneurs a glimpse into the future. As rapid download speeds and seamless connectivity take hold in cities around the world, tech entrepreneurs will have more opportunities than ever before to make an impact. With 11.5 million people having access to Sprint’s network already, imagine what will be possible as that number grows.5G will unlock new opportunities in every space. The healthcare, transportation, agriculture, and manufacturing industries will all be significantly more capable of innovation and growth as these networks take shape.Data on demandWe all know the frustration that comes from waiting for an app to load, a video to buffer, or an email to send. With an instant connection, 5G will not only eliminate these issues but also radically transform user experiences in several ways.Content streaming apps like Netflix and YouTube will benefit from faster download speeds. And so will social networks such as Facebook, Snapchat, and Instagram, which all use immense amounts of data to load images, video, and chat messages. But consumer-facing mobile apps are just the tip of the iceberg.The arrival of 5G will drive significant progress in emerging technology.Think of the power this kind of connectivity can give to things like autonomous vehicles, for instance. Driverless cars have to collect vast amounts of information, process it locally, and send it to the cloud. That data then goes back to the vehicle and enables it to make decisions. Thanks to 5G networks, this process will be nearly instantaneous.Virtually every connected device will become more reliable and effective because of 5G, too. IoT sensors will be able to process data, send it to the cloud, and act upon it at mind-boggling speeds. In essence, 5G makes the cloud almost instantly accessible and opens countless doors to technological innovation. And it’s increasingly becoming available across the globe.Emerging opportunities for entrepreneursThe building blocks of 5G are being put in place in cities all over the world. The U.K. launched its first public high-speed 5G network this spring, and major carriers like AT&T, Verizon, and T-Mobile have stateside deployments planned for later this year. In South Korea, the technology made its debut at the Olympic Village. Since then, a 5G network has been launched in Seoul, as well as in cities throughout China and Japan.As 5G infrastructures become more widespread, more opportunities will open up for developers to leverage their power.Tech entrepreneurs will be able to make everyday device experiences seamless and create entirely new ones with technologies such as VR and AR, industrial IoT, autonomous vehicles and drones, medical devices, and other connected hardware.AI and machine learning tools have already transformed multiple industries. But this disruption will pale in comparison to the near future. With unparalleled speeds and even higher amounts of data to leverage, these technologies will generate more profound insights for the people who need them most.The impact of 5G will be unprecedented.For entrepreneurs and investors looking to capitalize on it, here are four ways 5G will transform business:1. Interpersonal communicationCommunication drives business. Because consumers and downstream business operators are going to have access to devices that can send and receive data at lighting-fast speeds, they’ll be able to have better phone calls, higher-quality video meetings, and access to chat apps that don’t experience latency.When Verizon revealed its Moto Z3 phone, which works with the 5G Moto Mod that attaches to a phone, spectators watched it download a 1GB file in 17 seconds, a download speed that should be even faster on its commercial network. Phone usage and commercial network usage is just one example of the way 5G technology will drive stronger, more seamless business communications. Further, applications like these will directly impact and generate profits.2. Expanded remote work opportunitiesRemote work has already become standard practice at many businesses. With the advent of 5G, it’ll be possible for even more tasks to be accomplished remotely. At the Mobile World Congress, for example, a Spanish surgeon performed an operation from miles away with the help of a connected robotics kit.However, remote healthcare is just one example of the power of connectivity. Low-latency, high-frequency data transfers will make engineering and many other types of highly skilled work possible from anywhere with a decent connection.3. Tools driving innovationMany companies already use innovation labs to explore applications of emerging technologies. Soon, there will be a proliferation of devices and tools specifically designed to cultivate growth with 5G. Case in point: Verizon’s 5G Labs in New York and four other cities show businesses and consumers what’s possible with 5G while also providing startups and entrepreneurs with mentorship and advisory services as they learn to work with it.Companies will also soon offer DIY kits that enable anyone to build 5G solutions using components already available to them. For developers, these will present limitless opportunities. Organizations like MathWorks, for example, are already launching tools designed to help reduce learning and development time by giving developers a workflow to model after and use to test 5G systems for themselves.4. Venture capital interestVenture capital money is flowing into 5G enterprises in Silicon Valley, and those investments will continue to increase exponentially shortly. As just one example, the recent partnership established between Japanese telecom company KDDI and VC firm Global Brain Corp. will fund 5G infrastructure development.The golden age for enterprises focused on 5G or startups that are leveraging it is quickly approaching. As the marketplace continues to grow with the infrastructure and as the necessary hardware components for building with 5G tools become more ubiquitous, startups will have unimaginable opportunities to transform the world as we know it.One thing is certain: Nothing about 5G is moving slowly, and the race to harness the technology it makes possible won’t either.Feature Image attribution: avi-richards-Z3ownETsdNQ-unsplash-1-825×510 Why IoT Apps are Eating Device Interfaces Marc FischerCEO and co-founder of Dogtown Medialast_img read more
