A2 Hosting finds 'restore' the hardest word as Windows outage slips into May

The great A2 Hosting Windows TITSUP has entered its second week as the company continues to struggle to recover from a security breach that forced its System Operations team to shut down all its Windows services.

To recap, things went south on 23 April as malware spread over the company's Windows operation, causing a problem so severe that the A2 Hosting team decided the only way to recover was to restore data from backups. The company told furious customers last week that "Restores continue to progress at a steady pace".

Except, alas, things have not gone smoothly.

As some services gradually tottered into life, users made the horrifying discovery that the backups being restored from were less than minty fresh.

A "day or two" is bad enough for an ecommerce site, but the loss of several months' worth of data is an altogether angrier bag of monkeys. To make matters worse, the company has left it to users to work out just how whiffy those backups are.

Register reader David Sapery, who was lucky enough to see his services stagger back to life after a five-day liedown, was then somewhat embarrassed when his customers, finally able to access his sites, told him things looked a tad outdated.

Sapery told us: "Anything on any of my websites that was updated over the past 2+ months is gone."

Still, Sapery was at least able to recover. Another reader was not so lucky, describing his experience as "an unmitigated disaster."

Having spent eight months and "thousands of dollars", the unfortunate A2 Hosting customer told us that "my business and all my hard work has been gutted within seven days by a hosting company that clearly did not have robust security in place."

A2 Hosting will, of course, point to its Terms of Service where it makes it quite clear that it is not responsible for any data loss and that users are responsible for their own backups.

New OS takes on Apple, Android

Firefox, a web browser made by the non-profit Mozilla Foundation, was born as “Phoenix”. It rose from the ashes of Netscape Navigator, slain by Microsoft’s Internet Explorer. In 2012 Mozilla created Firefox os, to rival Apple’s ios and Google’s Android mobile operating systems. Unable to compete with the duopoly, Mozilla killed the project.

Another phoenix has arisen from it. Kaios, an operating system conjured from the defunct software, powered 30m devices in 2017 and another 50m in 2018. Most were simple flip-phones sold in the West for about $80 apiece, or even simpler ones which Indians and Indonesians can have for as little as $20 or $7, respectively. Smartphones start at about $100. The company behind the software, also called Kaios and based in Hong Kong, designed it for smart-ish phones—with an old-fashioned number pad and long battery life, plus 4g connectivity, popular apps such as Facebook and modern features like contactless payments, but not snazzy touchscreens.

With millions of Indians still using feature phones, it’s no surprise that this brainchild of San Diego startup KaiOS Technologies is already the second most popular mobile operating system in Indiaafter Android, capturing over 16% market share. iOS is second with 10%share, as per an August 2018 analysis by tech consulting firm Device Atlas.

The new category of handsets powered by KaiOS, which has partnered with Reliance Jio, require limited memory while still offering a rich user experience through services like Google Assistant, Google Maps, YouTube, and Facebook, among others.

Faisal Kawoosa, founder, techARC, credits KaiOS with bringing about a paradigm shift in infotainment in India. “This (the feature phone platform) becomes the first exposure of mobile users to a digital platform. It is also helping the ecosystem and new users to digital services without much increase to the cost of the device,” he said.

NHS to migrate to Windows 10 to upgrade cybersecurity defences

Microsoft on Saturday announced that The UK Department of Health and Social Care will transition all National Health Service (NHS) computer systems to Windows 10 to better protect against future cyber attacks. 

The Department has made a security deal with Microsoft regarding the same.

According to officials, the operating system’s more advanced security features are the primary reason for the transition, such as the SmartScreen technology equipped with Microsoft Edge and Windows Defender.

One of the other reasons for upgrading their security systems was the damages caused by the WannaCry ransomware attack last year, when NHS was one of the first victims.

“More than a third of trusts in the UK were disrupted by the WannaCry ransomware attack last year, according to the National Audit Office, which led to the cancellation of 6,900 appointments. WannaCry was an international attack on an unprecedented scale that affected organisations across the globe. While it did not specifically target the NHS, the impact on health organisations was significant,” read the announcement by Microsoft.

According to Kaspersky and Microsoft telemetry, over 98 percent of all WannaCry victims were Windows 7 users.

“We have been building the capability of NHS systems over a number of years, but there is always more to do to future-proof our NHS as far as reasonably possible against this threat,” said Jeremy Hunt, the Health and Social Care Secretary. “This new technology will ensure the NHS can use the latest and most resilient software available – something the public rightly expect.”

Qubes ~ An Open source OS Designed to Provide Strong Security


Qubes is an open source operating system designed to provide strong security for desktop computing. Qubes is based on Xen, X Window System, and Linux, and can run most Linux applications and utilize most of the Linux drivers. In the future it might also run Windows apps

Qubes lets the user define many security domains implemented aslightweight Virtual Machines (VMs), or “AppVMs”. E.g. user can have “personal”, “work”, “shopping”, “bank”, and “random” AppVMs and can use the applications from within those VMs just like if they were executing on the local machine, but at the same time they are well isolated from each other. Qubes supports secure copy-and-paste and file sharing between the AppVMs, of course.

Key architecture features:
  • BulletBased on a secure bare-metal hypervisor (Xen)
  • BulletNetworking code sand-boxed in an unprivileged VM (using IOMMU/VT-d)
  • BulletNo networking code in the privileged domain (dom0)
  • BulletAll user applications run in “AppVMs”, lightweight VMs based on Linux
  • BulletCentralized updates of all AppVMs based on the same template
  • BulletQubes GUI virtualization presents applications like if they were running locally
  • BulletQubes GUI provides isolation between apps sharing the same desktop
  • BulletStorage drivers and backends sand-boxed in an unprivileged virtual machine(*)
  • BulletSecure system boot based on Intel TXT(*)
(*) Indicates feature that is planned for future releases, currently not implemented.


Qubes OS is available for Download Here.

Minimum Requirments:

  • 4GB of RAM
  • 64-bit Intel or AMD processor (x86_64 aka x64 aka AMD64)
  • Intel GPU strongly preferred (if you have Nvidia GPU, prepare for some troubleshooting; we haven't tested ATI hardware)
  • 10GB of disk (Note that it is possible to install Qubes on an external USB disk, so that you can try it without sacrificing your current system. Mind, however, that USB disks are usually SLOW!)


Additional requirements:

Intel VT-d or AMD IOMMU technology (this is needed for effective isolation of your network VMs)

If you don't meet the additional criteria, you can still install and use Qubes. It still offers significant security improvement over traditional OSes, because things such as GUI isolation, or kernel protection do not require special hardware.

Note: They don't recommend installing Qubes in a virtual machine!

Let us See how much secure it is.

Top 10 Reasons Why Linux is better than Windows

1. It Doesn''t Crash

Linux has been time-proven to be a reliable operating system. Although the desktop is not a new place for Linux, most Linux-based systems have been used as servers and embedded systems. High-visibility Web sites such as Google use Linux-based systems, but you also can find Linux inside the TiVo set-top box in many livingrooms.
