USB Hacked

Listening to Padre of Know How, I learned a bit more about the possibility of BAD-USB devices being hacked and compromised. All the devices have upgradeable firmware which can be over-written and be compromised with malware.

Here are a few suggestions

  • Don’t share thumb drives and other USB devices with other people.
  • Don’t plug in random USB thumb drives into your computer.
  • This actually happened to my wife when she was part of a multi-company team – one thumb drive infected the computer they were all working on.
  • One solution would be to buy inexpensive thumb drives that if you use in someone else’s computer – you could then throw away.
  • SD Cards can also be hacked – but they are not nearly as vulnerable. This is preferable to using a thumb drive.
  • The best way left to move files safely is electronically – email, google drive etc.

Malware Removal Options

First off – don’t run as Administrator – when you get your system cleaned – change to a Standard User

Here’s a list of removal options below.

AV-TEST did a great report on these solutions – this link.

You can also try the old standard way of removing programs.

  • Control Panel – Programs – Uninstall
  • Config.sys – stop the programs from starting

IStart123 – very hard to remove.

I got rid of it on Chrome by uninstalling Chrome and then downloading a new version of Chrome. Here’s a video for other browsers.

Google Drive – Offline

While Google Drive is the way I keep most of my new files, when you don’t have internet access, it can be a bit aggravating when you can’t get to your files.

Even if you have setup Offline Sync, when you go to click on a file in Explorer, it’s really only a link to the file and nothing happens when you are offline.

Here’s how to view and edit those files.

  • Open up your Chrome browser.
  • Type in drive.google.com
  • Now you will have access to all your files even when offline.

WordPress – Miscellaneous Notes

I’m going to use this posting to collect miscellaneous things I learn about WordPress.com.

  • Zip Files – Can I upload zip files? Answer – Yes – IF – you have a space upgrade. (Instead of posting 20 files on one topic I wanted to upload just one zip file – that is possible if you have the space upgrade.
    http://en.support.wordpress.com/accepted-filetypes/
  • Audio Files, like mp3, also need the Space Upgrade. $20 for an extra 10 gb.
  • File Size – downsize all your graphics. You only get 3000 mb of space in your Media Library.
  • Space Left – To find out how much space you have used – Dashboard – Media – Library
  • Delete Media – You can delete items from your Media Library to make space for new items. Click in the box on the top right of each item – then go to the top of the page and under Bulk Actions click on Delete Permanently.
  • Upgrades Overview - you can buy ALL the upgrades for $99/year.

How to Setup a Guest Network

Steve Gibson, (SN-466) suggested this configuration for a “Guest Network” or possibly a wireless system for what they call the “Internet of Things.” When asked about the Security of Wireless routers which have “Guest Networks,” he responded, “I have no idea.”

Here’s the basic setup he suggests.

DPI – Dots Per Inch – Doesn’t Matter

One of the things which I’ve just recently learned is that for the internet, DPI or dots per inch, doesn’t matter. If you look at the pictures below they are all 640 x 480 pixels wide, but have different dpi. The top picture is 7 dpi, the middle picture is 72 dpi and the bottom picture is 350 dpi. Note that they all display the same and there is no difference in how they look.
