World Backup Day 2018

Saved Image 2018-03-31 at 11.39.26 AM.png

I can’t really say much more than I did last year, so I am reposting the article I wrote for Backup Day 2017.

If you have an electronic device (computer, phone, tablet), chances are that it can be backed up. Today, World Backup Day, serves as a reminder that you should be backing up those devices on a routine basis.

Backing up your data means making a second (and a third copy is recommended) of all of the data on your device. The 3-2-1 strategy is best – always three copies of your data, data stored on two different media, and one copy off-site.

You should backup because losing data is not as uncommon as you might think. Devices can be lost or stolen. Or they may simply suffer a hardware failure. Increasingly too there is the threat of the data on your device being held for ransom.

Start a habit today of making routine backups. You can even go to the World Backup Day website and take the pledge to back up your data.

One new thing I would like to add is this quick video by Bob “Dr. Mac” Levitus:

DON’T Plug in Just Any USB Drive!

Unknown

We have been aware of the threat of USB devices with auto-run malware for some time. More recently a worse device has surfaced, a USB Killer. This sounds like some fictional device you would see in a movie, but it is real.

This looks like any other USB drive, but the hardware is such that seconds after inserting it into a USB port, a disabling charge will be delivered. The USB Killer device charges up an internal capacitor from the 5V power supplied by the USB port. Once the charge reaches a high level (more than 200 volts) the capacitor is discharged back into the port. This process is repeated for as long as the device receives power. The power surge is fatal for most systems. The USB Killer device can then be unplugged and used again and again.

Not only have these devices been designed and tested, you can order one on-line from a Hong Kong company for less than $60. The product is advertised to “test USB ports for vulnerability”. Now at $60 each someone isn’t going to be buying and spreading the devices around, but it is cheap enough that someone up to no-good could purchase and then fry several several devices. How often do you see a laptop left unattended for a few minutes in a cafe?

The manufacturer claims “Our tests reveal that more than 95% of all devices using USB ports will be damaged permanently or completely destroyed by a USB power surge attack.” They do go on to say that “To date [August 16, 2016], the only hardware that resisted … tests was the latest model Macbooks ­which optically isolate the data lines on the USB ports.

If the evil doer is more creative, they can build their own device. I found one YouTube video where a $3 USB device was purchased on-line then modified to deliver a killing charge. Explicit “how to” instructions were given on how to weaponize the device.

What makes this scary and dangerous is that a recent study conducted by the University of Illinois, Urbana-Champaign, the University of Michigan and Google indicated that ‘found’ USB drives are often plugged into a computer. In this particular test 297 devices were spread around the University of Illinois, Urbana-Champaign campus. The result was that they found “that users pick up and connect an estimated 45%–98% of the drives we dropped.

Keep in mind that these USB Killer devices can affect any system with a USB port – computers, TVs, entertainment systems, autos, etc.

How do you protect yourself? If you find a USB drive do not plug it in!

macOD -MacHTTP.js

Product AnnouncementMacHTTP.Org of Leesburg, Virginia has released MacHTTP-js Preview for macOS, a full-featured Web server for 21st century desktops and servers. MacHTTP-js is a modern take on the classic stand-alone, desktop computer Web server plus a whole lot more, using current state-of-the-art technology while derived from the core ideas that went into the creation of the original Mac Web server, MacHTTP.

MacHTTP-js eliminates the need to understand arcane command line tools or to be an expert in deploying Linux-based servers. Instead, it returns to its roots as a double-clickable application with a friendly user interface allowing anyone technical enough to operate a text editor to set up a web server or create compelling Web applications on their desktop which can be migrated to public servers.

Implemented with modern technologies like node.js, Express.js, and Electron, MacHTTP-js is designed for upcoming versions to run on multiple different operating systems and computers, from Macs running macOS to Windows 10, various flavors of Linux (Ubuntu, Debian, RHEL, etc.), and even Raspberry Pis running Raspbian or container-based systems like Docker. These other versions will be released as part of the final release of MacHTTP-js, coming soon. This software is a Free Opens Source Software (FOSS) project.

The Preview version of MacHTTP-js runs on any version of macOS that is actively supported by Apple. For more information on MacHTTP-js, or to download the fully functional MacHTTP-js Preview version on macOS, free of charge, visit their web site.

RIP Dennis Ritchie

dr

I read today (“Dennis Ritchie, Father of C and Co-Developer of Unix, Dies“) that Dennis Ritchie had died. As anyone familiar with computer science knows he made huge contributions to the advancement of computing. He was the creator of my favorite (and still widely used) programming language C. He was also a key contributor to the development of the Unix Operating System. From Unix were derived Linux and macOS, both of which are widely used today alongside Unix.

He will be missed!

Another Source of Tech Information

screen-shot-2016-10-02-at-1-45-23-pm

I saw a article about How-To Geek, an online tech magazine, and thought that it might be something of interest to my readers.  It includes articles targeted at both the technical and general readers.

The site was founded in 2006. Articles are divided into the categories of Windows, Linux, Office, Gadgets, Mobile, Hardware, Apple, and Geek School. This might be a good addition to your ‘tech’ leisure reading.

I have subscribed to their RSS feed so that I get all of their articles in my RSS reader (I use the FOSS program Vienna).
