‘USB condom’ prevents device hijackings at rogue ports – NBC

usb-cable-endI know that sounds like a gag headline.  But if you need to plug your phone (or other device) into an unfamiliar computer just to get some juice then you need to know the risks.

Standard USB ports and cables have several electrical channels, some of which are used to transfer power, the others data.   When you plug in you risk:

  • Moving viruses between the computer and your device (in either direction)
  • Your contacts and photos being copied to the computer.  This can happen nefariously or, more commonly, because the computer helpfully performs a backup

A USB condom simply blocks the current on the data channels, meaning only the power channels make the connection between the device charging and the one being charged.

Simpler options are available, such as buying USB cables that only have the power parts installed, but they don’t offer anywhere near as good a headline 🙂

iPhones can auto-connect to rogue Wi-Fi networks, researchers warn

iphone_pwSecurity researchers say they’ve uncovered a weakness in  iPhones that force users to connect to Wi-Fi networks that can then steal passwords or other sensitive information.

AT&T iPhones instruct the devices to automatically connect to a Wi-Fi network called attwifi when the signal becomes available, a service designed to speed up browsing.  But attackers can set up their own rogue Wi-Fi networks with the same name and collect sensitive data as it passes through.  AT&T are not the only company that are doing this, so don’t be smug if you have another carrier.

Researchers tested their hypothesis by setting up several Wi-Fi networks in public areas that used the same SSIDs as official carrier networks. During a presentation on Wednesday at the International Cyber Security Conference, the Skycure researchers set up a network that 448 people connected to during a two-and-a-half-hour period. 

The most effective way to prevent iPhones from connecting to networks without the user’s knowledge is to turn off Wi-Fi whenever it’s not needed. Apps are also available that give users control over what SSIDs an iPhone will and won’t connect to.

Hackers attack WordPress ‘Admin’ accounts

ImageOver the past couple of weeks websites using  WordPress have been under fire from a very sophisticated brute force attack involving over 90,000 IP addresses. 

Some hosting providers handled this better than others.  

The best ones experienced  some slowness and minor outages while others simply went down for a couple of days.

While it has subsided the attack is still ongoing so here are a few steps that you should consider taking to help shore up your defenses.

  1. Make sure that your plugins are up to date.  Often plugin updates are released precisely because they have security holes and leaving these unattended for a long time is an open door to hackers.
  2. Don’t use administrator accounts called ‘admin’.  This is akin to using a password of ‘password’.  Some hosting vendors created these by default on installation.  If you have one of these then create another administrator account, log in using that one and delete the ‘admin’ account.
  3. Create strong passwords.  Ideally at least 8 characters and with a mixture of letters, numbers and special characters such as ^%$#&@*.  If you have too many passwords to keep things straight then consider using something like Lastpass.

These three simple steps won’t keep you totally in the clear but, like an alarm on your car, it should move the troublemakers on to an easier target.

Google Cloud Connect : The Free and Easy Alternative to SharePoint

Houldsworth's Random Ramblings

Unfortunately Google Cloud Connect has been shut down as of Aprils 30th 2013.  For more information and steps that should be taken if you already have this installed please visit this link:

MicrosoftSharePoint is a great collaboration tool but is far too complex for most small businesses and home users.   Fortunately the folks at Google have provided an answer that is both simple to use and totally FREE!   Google Cloud Connect for Microsoft Office .

Recognizing that 95% of the time Microsoft SharePoint is nothing more than a place to store and share documents Google has provided a way to merge that functionality very neatly into Google Docs .

Google Cloud Connect not only backs up your work to the cloud but also adds true collaboration to Microsoft Office, allowing others to simultaneously edit your documents while changes are automatically synchronized across computers. Finally everyone…

Virus Protect your PC with Linux (Dual-boot)

Install Linux alongside Windows to provide additional virus protection  and access your data if Windows becomes inoperable


Less than 1 Hour

InstallingLinux alongside Windows provides a number of benefits, even to novice users. Benefits to installing Linux alongside Windows (a practice known as dual-boot) include:

  1. The ability to run virus scanning software from outside of Windows – more on that later.
  2. Should the Windows system become unusable for any reason you can still boot into Linux to access and backup your files before any drastic action is taken with the Windows partition.
  3. If all you are doing is browsing the web then Linux will boot faster and be significantly more secure that Windows.

Note: The instructions below enable you to set up your machine as a dual boot device.  However if the unthinkable has already happened and your Windows PC is already…

Free Anti-Virus – The Best Way to Protect Your PC

Houldsworth's Random Ramblings

SummaryDifficulty RatingTime to complete
Replacing your existing Anti-virus with a free alternative. 20-30 minutes

As I mentioned in my last post, the first question I ask is whether people have a backup.   The second question ask is whether they have up-to-date anti-virus software installed.

A shocking number of people fall into the group of having anti-virus software that hasn’t been updated since their trial period ended, and yet still believe they are protected.

Let me make this clear – if your subscription has expired then you are NOT protected.

But who can blame them?  Anti-virus software is expensive, isn’t it?

If you go with what arrived on your PC then, yes, it is expensive.  PC manufacturers make extra money by including software (known collectively as Bloatware) because vendors pay them.  Norton and McAfee fully expect you to sign up when the trial period runs out…
