Three hospital worm infection dubbed 'substantive failure'
A worm attack that forced three London hospitals to shut down their computer networks late last year was entirely avoidable and represented a major failing by the organizations' IT staff, according to an independent review of the incident.
In mid-November, the Mytob worm wiggled its way into 4,700 PCs used by St Bartholomew's (Barts), the Royal London Hospital in Whitechapel, and The London Chest Hospital in Bethnal Green, and this forced the hospitals to reroute ambulances and scale back some "non-essential activities" while the infection was being contained. In some cases, doctors had to resort to pen and paper backup systems.
It took three days to restore key administrative systems such as email, and it took another two weeks to fully scan some 5,000 PCs belonging to the three hospitals, which collectively make up Barts and the London NHS Trust.
"The review concluded that the incident was 'entirely avoidable' and there was a 'substantive failure' of the Trust's information governance processes, 'especially those operational processes in the ICT domain,'" the independent review concluded. Only a portion of the report (PDF) was made public to prevent the airing of sensitive security details.
The failure at least partially involved the incorrect configuration of anti-virus software, which the report claimed left a back door for the worm to infiltrate the network. While the review didn't identify the package, IDG News says here that the hospitals used McAfee 8.5 anti-virus product, which had been able to identify Mytob for more than three years prior to the infection.
Mytob, which also goes under the name MyDoom, was introduced "accidentally" into the network with "no malicious intent," the report concluded without providing details.
The vulnerability of hospitals and other health organizations to malware attacks continues to be a major concern for administrators. Last month, hospitals around Sheffield in the UK came under attack by virulent worm known alternately as Downadup and Conficker. At least 800 PCs were confirmed to be infected, with many more potentially suspected.
The mass infiltration was allowed to take hold after administrators disabled Windows security updates, which were blamed for causing computers to reboot during surgery. Microsoft has offered a patch for the Conficker vulnerability since October, when it released an emergency update and strongly advised all customers to install it immediately.
The independent review offered 11 specific recommendations that fell into five categories:
- Additional training to specific staff groups
- Command and control arrangements
- Administration and documentation within the control room
- Categorized identification of Trust priority areas
- Register of staff skills that can aid Trust response
The report also found hospital staff were able to ensure patient safety even during the outbreak.
"The Trust maintained a safe environment for its patients and was able to keep its theatres and outpatients clinics operational throughout the incident," it stated. "No urgent operations were cancelled, although a very small number of other operations were postponed and immediately rescheduled." ®
Paper based system
You might as well have a paper based system if you have LINUX. Most of the applications used in the hospitals do not run natively on LINUX and need windows.
I was surprised that their machines were running XP. Not far from there a local Primary Care Trust still uses Win NT/2000.
If the rumours circulating the hospital were true there's not much technology defence from administrators who decide not to pay the maintenance fees for the Anti-Virus. However if that was true I'm sure it would have been made public in the report.
"Since XP SP2 it hasn't been insecure out of the box. It automatically updates, it has a firewall and you shouldn't need any vists to the desktop for support. Yeah, it costs. But it's also easy to work with and the admins are cheap. Management is a piece of cake and you KNOW there's an application - with support 24/7 - for nearly any application you need."
Two words: Ha ha.
Not that I'm advocating Linux on all NHS machines, or Windows on all NHS machines. I'm just laughing at the statement you made.
I don't play poker at work. I don't do ANYTHING at work.
