What Websites Know About You

Tech TipsWeb Tools – I wrote about using the privacy web tool WEBKAY for the first time (“What Can Websites Find Out From Your Browser?“) in July of 2017. While I was out walking today I was listening to an episode of the “Mac Geek Gab” podcast. They mentioned using WEBKAY and I thought it was time to revisit it.

WEBKAY

Screen Shot 2019-03-19 at 6.21.21 PM

What WEBKAY (What Every Browser Knows About You) does is to analyze your brower’s settings. Just open http://webkay.robinlinus.com in your brower and you will see a report displayed of what any website can find out about you! Among the datapoints displayed are:

  • your location (using your IP address)
  • the type of hardware the browser is running on
  • the operating system and version
  • the browser and version
  • what browser plugins you have installed
  • your public IP
  • your Service Provider
  • Your download speed
  • some of the Social Media sites you are logged into

While WEBKAY may not give as much detail in their report, they do provide suggestions on how to mitigate some of the findings.

Panopticlick

Another Web Tool that you may want to try is Panopticlick (https://panopticlick.eff.org) created by the Electronic Frontier Foundation (EFF). When you get to this site, click the “TEST ME” button.

Screen Shot 2019-03-19 at 6.25.24 PM

After several seconds you will see the test results displayed. It focuses on how well your browser is handling tracking. 

Click

Screen Shot 2019-03-19 at 6.36.38 PMA third site you might want to visit is Click (https://clickclickclick.click/). This site doesn’t give you a report as such, but it does display a running commentary on your actions while you are on the site. This is meant as a wake-up call to users as to just how much their browsers are revealing.

BrowserSpy

Screen Shot 2019-03-19 at 6.47.23 PM

Yet another web tool is BrowserSpy (http://browserspy.dk/). BrowserSpy can tell you much more information about your browser and system, but you have to individually select the test (there are more than 70 to choose from) to be run.

Browser Mirror

Screen Shot 2019-03-19 at 6.53.43 PM

Yet another web tool for assessing your browser is Browser Mirror (http://centralops.net/asp/co/browsermirror.vbs.asp). The report from this tool is similar to the others and gives a minimal report.

Staying Anonymous

There are a few things you can do if you want to be anonymous:

  • use a VPN
  • use your browsers private/anonymous browsing capability
  • turn off Javascript
  • block all cookies

NOTE: Turning off Javascript and blocking cookies may degrade how sites work or even prevent many sites from working at all.

macOS New App Release – VyprVPN

banner_mac

Did you know that connecting to the internet via an unsecured connection like an open wireless hotspot can leave your data at risk? With the right software, hackers can eavesdrop on your connection and intercept any data that hasn’t been encrypted. However, if you are connecting via a VPN that encrypts all your data and provides an anonymous browsing experience, any data will be unintelligible to them.

Stopping eavesdroppers isn’t the only security benefit afforded by a VPN. Since a virtual private network lets you browse the internet anonymously, websites can’t collect any data about you. Furthermore, websites and online services will think that you’re connecting from the place where the VPN server is located, which makes it great for navigating your way around geographical content restrictions.

Using VyprVPN for Mac from Golden Frog is the safest and easiest way to secure your internet connection using any computing running MacOS. It operates entirely without third parties and was recently certified by an independent report. Golden Frog, the developers, handle everything from end-to-end. In addition to encrypting your connection, it also offers many useful time-saving features like per-app connections, automatic server connections and more.

VyprVPN for Mac is regularly updated to improve performance, fix bugs and add new features that help you stay securely connected to your favorite websites and online services. In November, VyprVPN was also certified by the independent organization No Log VPN demonstrating its capabilities to keep your data safe.

Pricing and Availability:

  • VyprVPN for Mac is a free download and is available worldwide through the
  • VyprVPN website. A subscription for service is available at the same website.

The Story of Claude Shannon​ – The Father of Information Theory

511pvvcqgzl

Podcasts – I have mentioned the Internet History Podcast before. It is one of the podcasts that I subscribe and listen to on a regular basis. While the podcast “CLAUDE SHANNON, FATHER OF INFORMATION THEORY” was published back on May 27, 2018, I finally just got around to listening to it today and I wanted to share it.

This episode of the Internet History podcast deals with Claude Shannon. Specifically, it is an interview with authors Jimmy Sony and Rob Goodman. They have published the biography of Claude Shannon entitled “A Mind At Play, How Claude Shannon Invented the Information Age“. During the interview, they give a brief glimpse of Shannon’s life.

Shanon was a mathematician, electrical engineer, and cryptographer. he is most noted though for being the ‘father’ of information theory. His 1948 paper “A Mathematical Theory of Communication” laid the groundwork for modern digital communications. Just as important though was his work in digital circuit design theory. His Masters Thesis at MIT demonstrated that electrical applications of Boolean algebra could construct any logical numerical relationship. This is a foundation of modern digital computers.

In information theory, the Shannon–Hartley theorem gives the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. This formula, which I saw repeatedly in graduate school, is:

screen shot 2019-01-24 at 7.06.40 pm

where (from the Wikipedia page)

 

  • C is the channel capacity in bits per second, a theoretical upper bound on the net bit rate (information rate, sometimes denoted I) excluding error-correction codes;
  • B is the bandwidth of the channel in hertz (passband bandwidth in case of a bandpass signal);
  • S is the average received signal power over the bandwidth (in case of a carrier-modulated passband transmission, often denoted C), measured in watts (or volts squared);
  • N is the average power of the noise and interference over the bandwidth, measured in watts (or volts squared); and
  • S/N is the signal-to-noise ratio (SNR) or the carrier-to-noise ratio (CNR) of the communication signal to the noise and interference at the receiver (expressed as a linear power ratio, not as logarithmic decibels).

If you are interested in computers, mathematics or engineering, you might want to dedicate an hour to listen to this podcast.

Mac Software Sale – SimpleumSafe

Simp_EN_Sync_Bild1

– Under the motto “Now everybody can encrypt” the German company Simpleum Media GmbH of Hamburg, Germany offers a solution for Apple Mac and iOS which enables users to encrypt data without technical knowledge. Whether private or professional data, the protection of one’s own digital life is a priority and is a question of the responsible handling of personal and professional information.

In the case of professional data, companies are legally / contractually obliged to ensure the correct handling of personal and secret data in order to prevent access by unauthorized third parties. Whether contracts, strategy papers, patient reports, process documents or patents, these data require secure encryption so as not to fall into criminal hands.

  • Private users who want to protect their data
  • People who must take care about professional secrets
  • Professionals who must protect personal relevant data
  • People with security clearance such as doctors, lawyers, tax consultants, etc.(“confidentiality”)

Easy & Intuitive Usability:
SimpleumSafe combines intuitive operation and ease-of-use. To encrypt files or folders, drag files from the Mac “Finder” into the safe. Encrypted! You can organize your files similar to the Mac “Finder”: view files, edit, rename, comment and tag them, and your data always remains encrypted.

Features For Mac:

  • Synchronization of Safes between different devices (Mac, iPad, iPhone)
  • Simple and intuitive usability (drag a file or folder from Finder into a Safe and it is encrypted)
  • No technical knowledge is needed for encryption
  • Security made in Germany
  • Strong encryption with AES-256. All files in a Safe are encrypted
  • Store your safes locally, on USB device, and in the cloud
  • Create as many Safes as you want
  • App-to-App Drag & Drop: you can e.g. drag a mail, appointments, contacts, photos etc. directly into a safe
  • Organize your files as you like it (create folders, rename, copy, move, duplicate, trash, delete files)
  • Show file content for Microsoft Office and iWork, PDF, Images, Text, Videos, Audio and more …
  • Mark files and folders with tags
  • Number of files and size is only limited by the free space of your device
  • Thumbnailview/Image Viewer
  • Version 2.5 for Mac 10.14 Mojave with Dark Mode

Reviews:
“Everything I was looking for and so much more! …In no time I have created several Safes which contain among other things my tax records, financial information, and personal files. It is so easy to use and has a simple and intuitive interface. I cannot praise it enough. …If you are looking for a safe and easy way to store you important files I cannot recommend this enough!”

“Great app and best support! Simpleum Safe works great as stated. I have contacted support twice for two different questions and they have responded within a couple of hours and answered my questions perfectly. I recommend this easy and secure app to anyone that wants AES-256 encryption.”

“Amazing App! I’ve tried many encryption programs over the years, but nothing compairs to Simpleum Safe for keeping encrypted information on the icloud […] This is one of the best thought out and written encryption security programs I have ever seen. Very easy to use with lots of options such as taging files and attaching icons to the tags.. i.e. photos, documents, etc. […] Download and give this a chance you’ll be glad you did and you will probably fall in love with it.”

“Excellent! This app is very intuitive, easy and user friendly. Thank you very much. Far better than all others related apps.”

Why Choose Simpleumsafe?
Nowadays it is not enough “only” to encrypt your data to be protected. If you want to view or organize the encrypted files, they also must be protected. It is important not to leave any trace on the system, and even if a Trojan looks over your shoulder, it cannot copy all your files to the Internet.

SimpleumSafe goes a different way than most other encryption programs. After authorization with a password, the files are not provided in the file system. Otherwise they would be completely vulnerable from this moment on. SimpleumSafe makes its own file system and has its own finder. Thus the files remain encrypted for the entire time. Even if the synchronization data was stolen from the cloud and the password became public, it is not possible to decrypt the data.

Special Price:
SimpleumSafe for Mac is available from Cyber Friday (23.11.2018) until Cyber Monday (26.11.2018) for the promotional price of $17.99 (USD) (instead of $35,99) on the Simpleum website – in German and English. SimpleumSafe – best next generation encryption app – strong encryption, easy-to-use, continuously encrypted.

Significant Hardware Hack Alleged Against China

Updated 10/9/18

Cyber Security – I read the article “The Big Hack: How China Used a Tiny Chip to Infiltrate U.S. Companies” and . . . WOW. This reads like the plot to a science fiction thriller.

The idea of hardware being secretly hijacked during the manufacturing process has been around for a while. This allegation, if true, is significant! On the other hand, Apple has denied finding altered hardware in their official statement “What Businessweek got wrong about Apple“.

Since this article was just published October 4, I think there will be a lot of fallout over the next few days, weeks and months. It could have a significant impact on the cost of electronic products as supply chains reconsider off-shore manufacturing.

Added 10/9 – The article “Asian Countries and Industry Players Erupt over the China Spy Chip Controversy first started in the U.S.” still does not confirm the allegations against the Chinese, but it does indicate that there is a significant concern through the electronics sector.

Is Your Mac Infected with AdWare?

Tech Tip – Is your Mac infected with AdWare? Well, I guess the first thing is to explain exactly what AdWare is.

What is AdWare

AdWare is a term used to describe a form of malicious software (Malware) that displays unwanted advertisements on the infected computer. These may be in the form of a pop-up window or even an advertisement window that cannot be closed. While many consider AdWare only an irritant, it can become a major problem.

If your Mac is infected with AdWare it will attempt to change the way your browser and even your Mac functions. If your Mac is infected you may experience:

  • Advertising banners appearing on web pages that you visit
  • Being randomly redirected to another website
  • Browser popups appearing and recommending fake updates or other software
  • Your default search engine replaced
  • Icons appearing on your desktop for software you didn’t install
  • New toolbars, extensions, or plugins being added to your browser
  • Your Mac fan coming on or your battery depleting earlier than expected

Built-in Protection

How likely is it for your Mac to be infected? Much less likely that if you were using a PC, but there is a growing chance on your Mac being infected. Apple includes XProtect in macOS to catch Malware [7,8]. It has been part of macOS since 2009 and Mac OS X 10.6 Snow Leopard. XProtect scans downloaded files to see if any match the malware descriptions [6]. It does a pretty good job, but some software we might consider ‘malicious’ passes the test as legitimate software.

Screen Shot 2018-09-15 at 7.10.12 PM

Fortunately, XProtect is a macOS feature that is on by default and does not need to be enabled [4]. The only thing you need to do is make sure that the malware definition files are being updated [5]. Go to System Preferences ==> App Store and make sure the box next to “Install system data files and security updates” is checked.

You can also increase your protection by changing your DNS provider to Quad9. (See “Quad9, a Better Choice for your DNS“).

How to Check for AdWare

I came across the video [10] above by MacMost that gives a quick look at how to detect if AdWare is installed on your Mac. This is actually what got me started on this article. If your Mac is experiencing any of the symptoms listed earlier in this article, you should take a look to see if AdWare is installed.

The video shows a few of the common places to look for AdWare. There are actually several locations to look at and specific files to look for [11].

You may also want to review the installed Applications as well as check the Safari Extensions that are enabled. You should also go to System ==> Applications ==> Utilities ==> Activity Monitor. Under the CPU heading see if there are processes running with high utilization that you do not recognize. If you find any, do a search on them to find out what they do and if they are trusted.

Changing the DNS Provider on Your iOS Device

Tech Tip – Generally we all just let the network provider designate our DNS provider. You may want to change that and choose Quad9 for improved security, performance, and privacy for your iOS device. See that link for the story behind Quad9.

Changing the DNS provider on your iOS device is simple. Open Settings ==> WiFi.

IMG_1845

Click on the blue ‘i’ next to your selected WiFi network.

IMG_1847

Under the DNS heading click on ‘Automatic’ to the right of ‘Configure DNS’

Change the setting to Manual, then click on the ‘Add Server’ under ‘DNS Servers’ and enter the IP address of 9.9.9.9, then delete the others. Save your changes.

Now you are all set up to use the Quad9 DNS servers.

Unfortunately, you need to make this DNS change individually for every WiFi network you use. I am slowly updating both my iPhone and iPad to use Quad9 on each of the WiFi networks I use.

Quad 9, a Better Choice For Your DNS

Tech Tip – As you know if you follow my posts, I listen to a lot of podcasts. While nearly it is nearly 10 months old (I have quite a podcast episode backlog), I listened to episode #638 of the Security Now podcast as I went on a walk earlier today. The primary subject of this podcast was Quad9.

So what is Quad9? From their web page:

Quad9 is a free, recursive, anycast DNS platform that provides end users robust security protections, high-performance, and privacy.

Why would you want to switch to Quad9? The video above gives a short (2:29) overview of how DNS works to resolve Domain Names into IP addresses, and how Quad9 can provide you with more protection. The Quad9 claims:

  • Quad9 blocks against known malicious domains, preventing your computers and IoT devices from connecting to malware or phishing sites (Quad9 pulls in security intelligence from 19 partners including: IBM’s X-Force, Abuse.ch, the Anti-Phishing Working Group, Bambenek Consulting, F-Secure, Netlab, and Proofpoint)
  • Quad9 systems are distributed worldwide for quick response with servers in more than 128 locations at present. More than 150 locations in total are scheduled for 2018 (published tests demonstrate Quad9’s response time [1,5,7,8])
  • No personally-identifiable information is collected by the system [4]

The founders of Quad9 include IBM, PCH (Packet Clearing House), and the Global Cyber Alliance (GCA). Quad9 works with several partnering groups to make Quad9 a safer, more secure and private way to do DNS lookup. While they have extensive tech in place to block malware domains, Quad9 also has whitelisting in place to prevent known valid domains from being accidentally blocked [1,4].

After listening to Steve Gibson talk about Quad9 on Security Now I decided to switch to Quad9. Shortly after I returned to my apartment I logged on to my MacBook and set up Quad9. If you are not sure how to change your DNS provider on your Mac, the video above shows you how.

You should make the change to Quad9 on your Mac too! You can also set the DNS on your iOS device.

macOS New App Release – CyberByte Antivirus 2.1.1

imac

Product Announcements  – Independent development team CyberByte of Bucharest, Romania has released CyberByte Antivirus 2.1.1, an important update to their antivirus and internet security application for macOS computers. The comprehensive security app provides protection against threats by scanning for and removing viruses, malware, and adware. The utility also scans any local network for all connected devices, allowing users to ensure that no unknown devices are connected to their network.

CyberByte’s malware research team personnel are certified in malware analysis and incident response. The team updates the app’s malware patterns daily, based on currently developing malware campaigns. In addition, the app monitors the Mac Download folder, and alerts users if a downloaded file contains potential malware.

“While the Mac is generally considered to be safe and secure, there are still plenty of viruses, malware, adware and other threats lurking on the internet, ready to attack a user’s Mac,” says CyberByte CEO Calin Popescu. “My team at CyberByte has observed a 120 percent increase in Mac malware over the last year, which is why we developed CyberByte Antivirus for the Mac.”

CyberByte Antivirus is designed to be as easy as possible to use by home users, even if they don’t have much experience with computers. The app runs quietly in the background, monitoring for viruses, malware and other threats by constantly monitoring the Mac Downloads folder, ready to identify any malware that attempts to sneak its way onto the machine.

In addition to real-time monitoring for viruses and other threats, CyberByte Antivirus also offers the ability to manually scan any Mac for malware threats. Scanning for viruses by some apps can eat up large amounts of precious computing resources, slowing the computer and taking long periods of time to scan for threats. This can cause busy users to be reluctant to manually scan for threats. CyberByte’s solution quickly scans the Mac’s hard drive for possible threats, while the user can continue to work on projects and tasks, as usual.

Manual malware scans can be made in the form of a “Quick Scan,” which quickly checks critical locations on the Mac for any signs of a threat. A “Full Scan” indexes and searches the computer’s entire hard drive for malware. Meanwhile, the app’s “Adware Scan” function searches for any adware threats that could affect the macOS operating system and browsers.

Free Version Features Include:

  • Virus Scan
  • Adware Scan
  • Network Scan
  • Update Malware Patterns

Premium Version Features Include:

  • Remove Virus
  • Remove Adware
  • Active Live Protection
  • Premium Customer Support

An exclusive feature not seen in other antivirus tools is CyberBytes Antivirus’ ability to scan a local network, mapping the entire network and all of its connected devices. This ensures a hacker hasn’t taken advantage of recently discovered vulnerabilities in wireless network that allow the bad guys to hijack a network, stealing a user’s personal and business information, which can include passwords, banking and credit card information, and much more.

The “Network Scan” feature scans the network and reports back how many devices are connected to the network, returning information about the connections, including IP addresses and MAC addresses. By viewing the information, informed users can detect if an unknown device or computer has logged into their wireless network. For example, if a user knows they only have 3 devices attached to their network, (say, a Mac, 1 iPhone, and an Apple TV), they’ll be able to tell at a glance that a rogue network connection has been made.

“We here at CyberByte know you’ll find the new version of CyberByte Antivirus a valuable addition to your Mac’s protection arsenal,” continues Calin. “Our company provides security consultancy to large companies around the globe, and we give the same personal attention to our small business and home users. We look forward to receiving feedback about CyberBytes Antivirus, as we continually work to improve the app’s malware protection capabilities.”

CyberByte Antivirus will receive the OPSWAT certification of genuine antivirus solution later this month. The certification signifies the app has met all of the criteria designated for OPSWAT-certified desktop security applications.

System Requirements:

  • macOS 10.10 or higher
  • macOS High Sierra compatible
  • 64-bit processor
  • 181.6 MB

CyberByte Antivirus 2.1.1 is free, and is available worldwide exclusively from the CyberByte website. A premium version of the app, which offers additional features is also available for $24.00 USD (or an equivalent amount in other currencies).
