NHS Cyber Attack - There Are No Excuses


NHS Trusts still using Windows XP have been victims of a ransomware attack which has closed clinics and impacted patients - and it was entirely avoidable.

Microsoft flagged its Windows XP lifecycle dates early. Mainstream support ended in 2009, with extended support finishing in April 2014. These dates were known well in advance and yet 7% of computers remain on the 'dead' OS today. Far too many of them, apparently, within the NHS.

When the 2014 end of support date rolled around the UK Government entered a one year agreement to provide extended support for NHS Trusts who hadn't migrated to Windows 7 (despite seven years notice of the need to do so). This was an emergency measure to allow them to complete the transformation of their fleet.

It appears too many Trusts decided that lifecycle management of their IT estate wasn't worth the expenditure and did nothing. A decision which is now coming back to haunt them.

It appears there are also other PCs affected at Trusts which haven't been deploying Windows Security updates for later operating systems - Microsoft patched this exposure in March - another example of extremely poor management of IT estates.

Those responsible for IT in the Trusts affected need to answer for their actions. In many cases the decisions made will have been against the advice of those employed in the management of IT. At the very least each Trust should be able to show how it assessed the risks of retaining out of date Windows versions, who was responsible for accepting the risk and whether that was an appropriate decision.

This dramatic, headline grabbing and, above all, confidence shaking event should not be allowed to pass without those responsible being appropriately disciplined.

For now though, the focus needs to be on clean up. Individual machines will need to be wiped and restored - but hopefully not back onto XP. For most Trusts that will be sufficient to resolve this issue - barring the loss of any files stored locally on affected PCs.

For others though this may go further, with Windows Server 2003 vulnerable to the same problem - and support for that product having ended two years ago. If roaming profiles, network storage and application data is stored on WS2003 boxes there's a far bigger clean up operation in prospect.

Bad publicity is the last thing the NHS needs now, with an election upcoming and the imminent fight for its very existence looming large. Hard to think how this could come at a worse time.

F1: Robert Kubica Impresses In Renault Test Run

The car may be old but its the performance of the driver that's the story here. Robert Kubica returned to F1, after a fashion, earlier this week with an extensive test run in a 2012 Lotus Renault F1 car at Valencia.
The age of the car and the circuit were likely determined by F1's current rules which ban testing, but the reason for Kubica being in the car is far more interesting. Considered by many to be a potential World Champion and certainly one of the fastest drivers of his generation, Kubica's F1 career seemed to be over after a 2011 crash whilst driving in the Rally of Andora. His Skoda Fabia was penetrated by a guardrail in the high speed accident partially severing his right arm.
Up until last year Kubica has been competing in rallying, with the expectation that the limited movement in his repaired arm would prohibit a return to single seater racing.
So this week's test is both interesting and confusing. Interesting because Kubica completed 115 laps of the ret…

F1: Robert Kubica's Williams Test Asks More Questions Than It Answers

Comparing driver's times at a tyre evaluation test like last week's Abu Dhabi event is difficult at the best of times, but when trying to assess the performance of a driver who has been out of the sport for six years, that difficulty level is raised even higher.
On the face of it Robert Kubica's test for Williams was a success. Fastest of the three Williams drivers present the headlines look promising. However, taking into consideration the different tyres used to set those times muddies the water considerably.
Kubica ran a three lap qualifying simulation on the new 'hyper-soft' tyre - which should have given him a two-second advantage. Correcting for tyres it would appear that Kubica was significantly slower than Sergei Sorotkin - who was on the harder 'soft' tyre - and marginally quicker than Lance Stroll, the team's only contracted driver.

Stroll's family fortune currently funds Williams, so there' no chance that he will be anywhere but in a…

Panos Panay's Defence Of Microsoft Surface Hardware Sounds Eerily Familiar

This weekend I went out with my ten year old daughter to select a laptop for her school year beginning in January. The schools requirements are quite specific, requiring a Windows 10 device, with a preference for a touchscreen and a stylus. She chose a Surface Pro, after trying a large number of different options. Having seen the way I use my own Surface Pro - and tried it herself there was only ever going to be two options - and the other was a Surface Laptop.
I tell you this so that you understand I am a buyer of Microsoft's products through choice, not compulsion. I'm on my third Surface device now. 
So when Panos Panay dismissed reports of the death of the Surface hardware line, I was very interested to see exactly how strong these denials were. Especially how they reflect what has gone before. To whit: Windows 10 Mobile.
Panay claimed that Microsoft is in hardware for the long haul. Almost exactly mirroring the words of Terry Myerson, when he claimed Windows Mobile was g…
