A last note on the Cyber-attack debacle

Map RansomwareYou are most likely sick and tired of hearing about the attack of  Ransomware and similar worms, however, it is a fact that most Windows PCs were vulnerable to remote attack due to dud Windows Defender, the protection installed by default on all consumer oriented Windows PCs.

Without going in to all the technical details suffice it to say that Microsoft has now – and it must be said with impressive speed – issued an automatic patch to guard against the remote code execution.

The interesting thing about this whole story is

Newsletter for May 2017

With the recent Ransomware Cyber Attack around the world, it is a timely reminder to each of us to ensure that the computer we are using has the latest updates and that we also regularly back up each device.  The articles below you may find informative and helpful.  However, if you do have any questions please do not hesitate to ask a Tutor at one of our classes or a How Do I…? Workshop.

What is a computer virus? (Microsoft.com)

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.

You Don’t WannaCry… Do You?

You’d have to be living in a cocoon to have missed the reports in the mainstream media this week about the WannaCry Worm which has infected vulnerable computers around the world. WannaCry is transmitted when people open infected email attachments and can spread itself quickly within organisations over their internal computer networks. Home PCs and laptops are just as vulnerable!

What is WannaCry?

It’s a computer worm categorised as ransomware! When a PC (or laptop) is infected by WannaCry or any of its variants, important files are encrypted (scrambled) and can no longer be read or used. The primary target is your documents and pictures.

Once infected, you have to pay a ransom to gain access to your documents and pictures.

How do I recover from a WannaCry Infection?

If you want to recover (decrypt) your documents and pictures, you have to pay $US300 in Bitcoins to some ratbag. If you take more than 3 days, they double the charge to $US600 and after 6 days, they simply walk away leaving your PC information completely inaccessible.

If you don’t want to pay the money, you better have a (recent) backup of your documents, pictures, music and videos. You’ll likely need to reset your PC (reinstall Windows!) to remove the infection and then restore your documents, pictures, music and videos from the backup.

If you want to avoid having to choose a recovery method then read on… Continue reading

What is Enlightenment?

KantThis question was posed by Immanuel Kant [Philosopher] back in 1784 and you may well wonder if we have become more enlightened when we read of all the political bickering going on around us.

Immanuel Kant went on to say that “Enlightenment is man’s emergence from his self-imposed immaturity.

Immaturity is the inability to use one’s understanding without guidance from another.”

You see my point.

The Weird and wonderful

Particles

At various times the words ‘Quantum computing’ and ‘Quantum mechanics’ as well as ‘Quantum nano computers’ were mentioned in past posts.

There is a good reason for that because whilst on the one hand the whole quantum business is really weird, on the other it is wonderfully amazing and it is not long now before some startling computing results can be expected.

That means that for us mere mortals the concepts will begin to have greater meaning so we need to know a little more than just the name ‘quantum computing’.
