Protecting against ransomware - is this possibly a different way of thinking about it in the SOHO space?

Recently my folks got an email from their ISP (Westnet) scaring them, thinking they'd been hacked (it turns out an old Westnet user database had been compromised, along with cleartext usernames and passwords... oopsies?).

Before I figured out what it was, I was thinking suspicious activity had been detected on their accounts and was worried about whether or not they'd backed up recently... then my thoughts turned to cryptoware and how it basically spreads out to whatever it touches and encrypts everything (had someone else hit by a bug recently - and I'm moving them and their formerly Windows XP computer to Lubuntu as they only need Windowsish looking email, web browsing and printing).

Anyway.. long setup aside, I was thinking, that perhaps the best way to deal with backups and cryptoware, was to have the system that needed to be backed up make itself available to an authorised backup storage provider by some restricted and secured means (over a LAN or encrypted link). That backup storage provider could be prodded by the client system to perform a pull, but the client would never have direct, unrestricted access to the backup server's archives.

How to turn off showing the margins (aka whitespace) in Excel 2010 Page Layout mode

It was driving me nuts at work, this particular spreadsheet we have. On two tabs it was showing the margins, and on two other tabs, it wasn't. I didn't need to see the margins, and for the life of me I couldn't figure out how to make things consistent.. Then I figured it out when I hovered my mouse over the area!

Mobile devices aren't particularly secure...

Going through my news feed, I see an article in Engadget about how Boston, Massachusetts with the help of Cisco wants to install wireless charge stations that also report on environmental quality (such as noise and air pollution).

I think there's some gotchas here...

Weird noise from my phone...

Awhile back, I noticed that every so often, my phone would make a weird sound and I couldn't figure out what it was.

Experience with a Telstra Samsung Galaxy Nexus Google Phone

I've had my Telstra Samsung Galaxy Nexus (I-9250TGSMH) for almost a year now (it's September now, and I bought it the January before last). Overall I'm happy with it, but there are also some things I'm not entirely convinced by or thought should have come standard...

So, what does that security vulnerability do on a Samsung Galaxy Nexus running stock Android JellyBean 4.1.1?

Thanks to Mikeybear to highlighting this one for me on Facebook and Dylan Reeve for a nifty testing tool and an example.. It seems that some Samsung Android handsets have a vulnerability that allows invoking USSD codes from a browser with minimal user interaction.

Not seeing anything about my particular handset, the Samsung Galaxy Nexus, I decided to test it out.
