What Michigan City Has The Fastest Download Speeds

fastest download speedsThe politicians in Lansing are not known for doing anything good quickly. But they do have fast internet. New rankings from RootMetrics showed that Lansing, Michigan had one of the fastest download speeds in the U.S. during the second half of 2020. Lansing ranked 6th out of 125 markets in the RootMetrics report.

Fastest download speeds in Michigan

Lansing’s median download speed across the major carriers was 43.7 Mbps. Michigan’s capital city had faster aggregate median download speeds than tech-heavy markets. Lansing ranked better than Chicago (36 Mbps), San Fransico (34.6 Mbps), Dallas (32.3 Mbps), or Los Angeles (31.6 Mbps). 

Michigan metro’s rated surprisingly well, overall. 

  • Detroit ranked 16th nationally at 39.5 Mbps.
  • Ann Arbor came in 47th with 34.4  Mbps.
  • Flint‘s 31.8 Mbps earned it the 59th spot.

The article says that speeds of 30 Mbps are typically fast enough for users to enjoy smooth gaming and fast file downloads.

the worst download speeds

Slowest download speeds

The metropolitan areas with the worst download speeds are spread across the U.S.  The report says Antelope Valley, CA (20.0 Mbps), Madison, WI (19.3 Mbps), and  Fresno, CA (18.8 Mbps) were the worst.

RootMetrics told FierceWireless smaller markets like Lansing have some advantages over the mega-markets like Chicago or Los Angles.  Rishikesh Bhandari, RootMetrics RF engineer explained,

Technology rollouts and the optimization of those technologies (such as 5G or higher-order carrier aggregation, among others) can often take longer in bigger cities precisely because of size …  there are far more people for the carriers to serve—and over much larger geographic distances … the carriers must ensure smooth technology deployments … and that can take time, especially in bigger cities, with millions of people and thousands of square miles to cover.

How they test the fastest download speeds

RootMetrics conducts its tests with unmodified Android-based smartphones purchased off the shelf at regular mobile phone stores. To determine which metropolitan markets across the U.S. were home to the fastest and slowest speeds, the Bellevue, WA based firm aggregated the overall median download speeds recorded across all network technologies (4G LTE and 5G, where applicable) for AT&T (T), T-Mobile (TMUS), and Verizon (VZ)n in each of the 125 most populated metropolitan markets in the country and ranked them from fastest to slowest.

Blue Front Closing

Blue Front ClosingThe 90-year-old Blue Front store is closing. The store at the corner of Packard Street and Arbor Street in Ann Arbor is shutting down for good Saturday. When I was on campus in the mid-’80s, Blue Front at 701 Packard Street sold beer, wine, newspapers, sundries, and snacks. In 2014 the campus tradition was converted to a craft beer store.

Blue Front - Ann Arbor

I remember the Blue Front. It was the place I would stop to get batteries for my Walkman, an extra roll of TP, beer, and munchies going to or from campus.

This is not surprising to me. Combine campus being deserted due to COVID-19 lockdowns with the decision to move to a $20.00 a bottle craft beer model in a student area with no parking.

Stay safe out there!

Barracuda Networks Has Been Bought

Barracuda Networks Has Been BoughtWhile the massive Equifax data breach is still fresh in everyone’s minds and the cybersecurity workforce is expected to be short nearly 2 million people. IT security expenditures to top $1 Trillion by 2022. Private equity giant Thoma Bravo, LLC has jumped back into the IT security market with both feet. Barracuda Networks has been bought by the private equity firm in a deal that’s valued at $1.6 billion.

BarracudaBarracuda (CUDA) sells appliance and cloud-based cybersecurity and data protection services. Clients include; Boeing, Microsoft and the U.S. Department of Defense. Barracuda says it has over 150,000 customers. Upon the close of the transaction, Barracuda will operate as a privately held company.

Barracuda Networks has been bought

Barracuda Network was founded in Ann Arbor, Michigan in 2003. From Ann Arbor, it raised at least $46 million in venture funding prior to its IPO. CUDA went public on the New York Stock Exchange in November 2013, pricing its IPO at $18. Barracuda acquired Yosemite Technologies in 2009 to expand its offerings into the storage market.

Barracuda NexGen FirewallBarracuda continued to innovate in the run-up to its acquisition. eWeek reports that in March 2017, Barracuda debuted new data backup and recovery capabilities for VMware and Microsoft virtual machines. In June 2017 Barracuda announced its new Sentinel service. The service uses artificial intelligence (AI) and container-based technologies to improve email security.

Barracuda also enhanced its network security products and services in 2017. eWeek reported in November that the company expanded the cloud capabilities for its Web Application Firewall (WAF) and NexGen Firewall products. The new capabilities include usage-based billing for the NextGen firewall running in the Amazon Web Services (AWS) cloud. The firewall included automated configuration capabilities for the WAF, thanks to an integration with the Puppet DevOps tool.

CEO BJ Jenkins commented on the transaction, “We will continue Barracuda’s tradition of delivering easy-to-use, full-featured solutions that can be deployed in the way that makes sense for our customers.

Thoma Bravo

Thoma Bravo is a Chicago-based private equity firm with $17 billion under management. Their appetite for IT firms is rather broad. Some of it’s most notable purchases have been:

  • Thoma Bravo is a Chicago-based private equity firmSeptember 2014 – $2.4 billion purchase of Detroit-based Compuware.
  • December 2014 – $3.6 billion acquisition of Riverbed.
  • In October 2015, they teamed up with Silver Lake to buy IT infrastructure management vendor SolarWinds for $4.5 billion.
  • April 2017 – Purchased a minority stake in the freshly re-spun McAfee.
  • June 2017 they purchased Remote Monitoring and Management (RMM), IT security management vendor Continuum.

Their portfolio has included brands such as; Bomgar, Digicert, Digital Insight, Dynatrace, Hyland Software, Imprivata, iPipeline, Nintex, PlanView, Qlik, SailPoint, and SonicWall.

Thoma Bravo has resold many of its holdings in recent years.

TechCrunch notes that private equity firms began more aggressively buying up software companies last year. The thinking seems to be they can generate reliable returns from such investments. The biggest take-private deals lately include:

  • Marketo, a marketing software maker. Went public in 2013 and was taken private again by Vista Equity Partners in 2017 for $1.79 billion in cash;
  • The sale of event-management company Cvent last year to Vista Equity Partners in a $1.65 billion deal.
  • Cybersecurity risk-monitoring platform SecurityScorecard raised $27.5 million from the VC arms of Google, Nokia, and Intel.

Other notable IT security equity funding recipients include; Attivo NetworksDarktrace, and SentinelOne.

Investopedia speculates that Thoma Bravo is paying a pretty high premium for Barracuda. CUDA now trades at 139 times earnings and 4 times sales. But under private management, its products will likely be integrated with the firm’s other software products to generate synergies.

CRN notes that being a privately owned company will give Barracuda a stronger ability to chart its own destiny. They will not have to “tap-dance to the Wall Street music,” Michael Knight, president and chief technology officer at solution provider Encore Technology Group, Greenville, S.C., said. He hopes Thoma Bravo’s infusion of capital will enable Barracuda to continue driving its public cloud business, a more solidified SD-WAN toolset, and more integrated endpoint security protection.

I have used Barracuda products at past jobs. Including their SPAM-Email firewall appliances and their cloud-based backup up system. The pricing was adequate. Renewals were easy. The email firewalls were really robust and almost set and forget.

The few times when I needed tech support, it was available in Ann Arbor, Michigan. Barracuda, founded in Ann Arbor, was one of the early believers in the area as a high-tech hub. Barracuda has plans to spend  $2.3 million on the expansion of its operations center in the former Borders Books offices at 317 Maynard Street. The expansion will add 115 new jobs in downtown Ann Arbor over the next four years. I hope that after Barracuda Networks has been bought by Thoma Bravo, the deal does not have a “Chainsaw Al” that will kill that growth.

Slam the Door on Hackers

Slam the Door on HackersLast year two white-hat hackers Charlie Miller and Chris Valasek, remotely compromised a Jeep Cherokee. The cybersecurity researchers used  existing functionality in the car to take control.  They were able to disable the car’s transmission and brakes, while the vehicle was in reverse, and take over the steering wheel.

Karamba SecurityThe Verge reports the researchers are back and have compromised their Jeep Cherokee, fooling the car into doing dangerous things. Things like turning the steering wheel or activating the parking brake at highway speeds. This year’s attack requires physical access to the car.

Hackers use the diagnostic port

The team used a laptop connected to the OBD II engine diagnostic port to control even more vehicle systems. The Verge says the researchers were able to update the electronic control unit. This allowed them to take control of the steering at any time. They could turn the steering wheel at any speed, activate the parking brake, or adjust the cruise control settings.

Electronic control unit

Most operations in a car have their own designated electronic control unit (ECU) controller. Some ECU’s manage things like a car’s navigation and entertainment systems. Others manage more critical systems like braking and fuel injection.

Radio are a gateway for attackersA connected car’s ECUs all operate on one network, self-contained within the vehicle. Tel Aviv start-up Karamba co-founder David Barzilai, warns. “If hackers gain access to just one of these controllers, they can get to all of them.

Harden ECU

The Israeli company hopes to sell Carwall Detroit automakers. Carwall is a tool that installs anti-hacking technology into chip-bearing auto parts before they hit the assembly line. Rgis could prevent hackers from crashing your new connected car. Mr. Barzilai told TechCrunch the startup’s technology can head off hackers at the pass. Carwall “hardens” the controllers, or small computers, within a vehicle that are externally connected.

Carwell, a tool that installs anti-hacking technologyKaramba’s Carwall is installed on the controllers, either as a retrofit or before the controllers are built into new cars. The software locks in the factory settings, and prevents any foreign code or banned behaviors from running on them. This essentially blocks a hackers ability to reach into a car’s CAN Bus, and mess with the car’s critical functions.

If indeed we are successful – if all hacks are blocked – then [you] don’t have to worry,” said Karamba’s Barzilai. “A hack that crashes your software is bad enough. A hack that crashes your car takes it to a whole new level.

Karamba’s technology is designed to monitor every bit of code that tries to run on the ECUs and to make sure it comes from legitimate sources. “We are the gatekeepers,” Mr. Barzilai told MiTechNews.

Out of stealth mode

monitor every bit of code that tries to runTechCrunch says Karamba has not yet scored a contract with top automotive suppliers that make ECU’s. They are targeting firms like Continental, Robert Bosch, Delphi Automotive, or Panasonic. But it has only just emerged from stealth and begun to shop its security software around.

YL Ventures has invested $2.5 million to fund Karamba’s growth, MiTechNews reported. Compared with the funding that some Silicon Valley security companies pick up, that’s not a huge amount. But it’s enough to move CEO Ami Dotan to Ann Arbor, where he’ll start making sales calls.

Karamba isn’t alone in attacking car security. Symantec (SYMC), the old school antivirus firm is working on auto security within its “internet of things” unit. Symantec recently released a  white paper “Building Comprehensive Security into Cars,” (PDF) detailing the many electronics and sensors that have to be protected.

Chrysler is doing a small part to reduce connected car hacking. They recently launched a bug bounty program with Bugcrowd that will pay out as much as $1,500 per bug found. On the other hand, Apple is offering a bug bounty of up to $200,000 for bugs that won’t kill you.

Security Cam Concerns in Ann Arbor

Security Cam Concerns in Ann ArborNext time you are in Ann Arbor to get a bite to eat at Zingerman’s or attend a U of M football game at Michigan stadium someone may be watching you. NetworkWorld, says Ann Arbor is one of the top U.S. cities with the most unsecured security cameras. In fact, Ann Arbor ranks seventh nationally.

The report’s author, security firm Protection 1, analyzed the data from Insecam. Inseacam identifies open security cameras and Protection 1 estimates there are over 11,000 open security cameras on the Internet in the U.S. Protection 1 identified the cities with the most cameras that can be viewed by anyone online. The top 10 cities with unsecured security cameras are:

  1. open security camerasWalnut Creek, CA – 89.69 / 100,000 residents
  2. Richardson, TX – 72.74 / 100,000 residents
  3. Torrance, CA – 72.55 / 100,000 residents
  4. Newark, NJ – 38.07 / 100,000 residents
  5. Rancho Cucamonga, CA – 36.76 / 100,000 residents
  6. Corvallis, OR – 37.98 / 100,000 residents
  7. Ann Arbor, MI – 34.18 / 100,000 residents
  8. Orlando, FL – 34.05 / 100,000 residents
  9. Eau Claire, WI – 22.21 / 100,000 residents
  10. Albany, NY – 20.32 / 100,000 residents

using the manufacturer's default passwordOpen security cameras connect to the Internet via Wi-Fi or a cable. They have no password protection or are using the manufacturer’s default password. Malicious people and governments can record or broadcast our lives from unprotected open security cameras. Open cameras are also vulnerable attacks that can turn them into bots.

From a privacy perspective, the most worrisome finding is that 15% of the open cameras are in Americans’ homes. Anyone can watch these cameras if the default password is not changed to a unique password to lock down the camera.

Besides being spied on from the web, open cameras can be exploited by criminals. Cyber-criminals can force online cameras to attack other things on the Internet as part of a DDoS attack.

distributed denial-of-service (DDoS)A DDoS attack against a jewelry shop website led to the discovery of a CCTV-based botnet. A distributed denial-of-service (DDoS) attack is one in which a multitude of compromised systems attack a single target, thereby causing a denial of service for users of the targeted system. TargetTech says the flood of incoming messages to the target system essentially forces it to shut down, thereby denying service to the system to legitimate users.

Help Net Security reports that Sucuri researchers discovered the jewelry site was being attacked by a CCTV botnet made up of 25,000+ cameras from around the globe. The website was first attacked by a layer 7 attack (HTTP Flood) at 35,000 HTTP requests per second and then, when those efforts were thwarted, with 50,000 HTTP requests per second.

Sucuri researchers discovered that all the attacking IP addresses had a similar default page with the ‘DVR Components’ title. After digging some more, they found that all these devices are BusyBox based. Busybox is a GNU-based software that aims to be the smallest and simplest correct implementation of the standard Linux command-line tools.

CCTV botnet made up of 25,000+ cameras from around the globeThe compromised CCTV cameras were located around the globe:

  • 24% originated from Taiwan,
  • 12% United States,
  • 9% Indonesia,
  • 8% Mexico,
  • and elsewhere.

Unless something is done, security flaws, misconfiguration, and ignorance about the dangers of connecting unsecured devices to the IoT will keep these botnets functioning well into the future.

block or absorb malicious trafficTo protect your website from botnets and DDoS, you need to be able to block or absorb malicious traffic. Firms should talk to their hosting provider about DDoS attack protection. Can they route incoming malicious traffic through distributed caching to help filter out malicious traffic — reducing the strain on existing web servers. If not find a reputable third-party service that can help filter out malicious traffic.

DDoS defense services require a paid subscription, but often cost less than scaling up your own server capacity to deal with a DDoS attack.

Arbor Networks is one firm that provides services and devices to defend against DDoS.

Google has launched Project Shield, to use Google’s infrastructure to support free expression online by helping independent sites mitigate DDoS attack traffic.
