Not backing-up Your Digital Life?

cloud1When was the last time that you did a back-up of your PC? It is a good question and an important one. We have recently conducted a survey to ascertain people’s views on back-up and you can follow this link to it. If you follow this link it will take you to a YouTube video we have also created on the results from this survey. We found that only one third of us carry-out a regular backup. Only one in five us backup all of our content..  There seems to be a consensus that the content we are gathering and creating on our PCs grows at circa 50% per year. That would suggest that backing up content is important. The reasons given for people not backing up are those of complexity and never seeming to have the time.  I believe that, as with a lot in our new digital life, the internet can also be the source of a solution. The ability to backup our important content to an online backup service is now here with us. It offers the ability to access your content from wherever you have access to the internet. You are no longer tied to, nor reliant upon, standalone hardware based backup.  The beauty of this approach is that the content can follow you around, not you having to go and chase it. That is why we here at Symantec have just released Norton Online Back-up, a web based backup service. It’s ambition is to make back-up convenient and simple and to provide the peace of mind that we all want and need when it comes to securing our digital life.

Netflix in need of a fix

At the time of writing this, the US online video service, Netflix is still attempting to recover from an outage. This is now the third day, that the company has been affected. They cannot send confirmations back to customers to have returned DVDs to them, nor process orders for new rentals. Ouch!

There have been no details, that I can see, as to what has caused the problems.  In a curious turn of events however, the streaming video service is up and online and still being able to service customers. Is this a case of the companies online business showing its worth versus the off-line business? Well maybe not, we have to remember the off-line (no pun intended) business is down, is due to ‘IT system’ issues. 

This is yet another reminder of just how dependent companies are on their systems. The implications are significant. The loss of revenue and hence, one would assume, profit. The inconvenience to the customer of not being able to get the films they wanted. All this ends up in a significant hit to the brand image – this can be seen in comments left on the company Blog site. A timely reminder to all of us, to ensure that we have a plan in place ‘just in case’. I am off to run a backup of my laptop!

The $160Billion question?

The security focused news-wires have been busy this past week reporting on the impact of ‘ransomware’. This is in response to the discovery of a new variant of Trojan.Gpcoder. This is a particularly nasty threat that uses public key cryptography to encrypt files on a person’s computer and subsequently requests payment from the user in order to recover the files.  What was newsworthy about the new variant was that it was using a 1024-bit encryption key. In lay-man’s terms, this means that it is tough to crack the code to release the encrypted data.

The latest variant of the virus, first reported on June 4, appears to not have the implementation flaws of previous versions. While 1,024-bit keys are considered weak for high-security applications, the encryption is strong enough to foil reasonable attempts to brute force the solutions. In a blog on the Symantec Security Response site, Eoin Ward, notes that by some estimates a machine that could break one 1024-bit RSA key in about a day, would cost $160 billion when adjusted for today’s prices. Wow!

Ransomware has been about for quite a while. It is a nightmare scenario for many users, However, it is relatively uncommon, simply because it is hard to ‘cash-out’. By that, I mean the ability of the bad guys to get money for it.  They have to setup a payment mechanism to get the ‘ransom’ and in doing so, they make themselves vulnerable to being detected.  In those cases that people have paid up, the ‘ransom’, has tended to be pretty low i.e. in the range of $50-$100. So, I don’t think there is any prospect of $160 billion being spent to solve this. So, what is to be done?

Well, what this incident brings to the fore is the need for regular backups. This will mean you have something to fall back to, if you were to fall foul of this type of attack. Now, whilst the debate rages on about how to generate a key to decrypt this variant of Trojan.Gpcoder, definitions have been created and released to identify it. Therefore, ensure your AV definitions are up-to-date.
