Hackers have exploited a security vulnerability in the Linux kernel, specifically the sys_vmsplice call that is responsible for virtual memory management, to gain root privileges within some of Claranets servers.

The UK business ISP first spotted the problem during Tuesday afternoon, although by then the hackers had already managed to replace their customers index.html (website) files with an unspecified message:

Claranet Statement: "Malicious activity related to the vulnerability was detected on claranet's shared hosting platform. Within 10 minutes claranet contained and halted the malicious activity, and locked down the platform to prevent further damage.

The shared hosting platform was fully patched with the vendor's updates by 10am on Wednesday. Less than one per cent of the total web sites hosted on the claranet platform were affected and all were restored to their original states by 1pm on Wednesday 13 February

The situation, which is covered in more detail HERE (The Register), first appeared in version 2.6.17 of the Linux kernel and wasn't resolved until 2.6.23.

Every time you connect to the Internet an IP (Internet Protocol) address is assigned to you, which under current IPv4 standards typically takes the form of four number groupings (e.g. This is your unique online identifier and allows you to communicate with Internet servers and services, such as e-mail or websites.

However you can only have so many billions of IPv4 address combinations before running out and the online population is fast outstripping the available number pool. Thankfully there has long been a solution, IPv6, which we explained back in October last year (here).

On 4th February 2008, IPv6 IP addresses can be directly translated into domain names and vice versa. This is one of the most important steps to date in the race for implementation of the new IPv6 protocol before the exhaustion of IPv4 addresses, which are predicted to start running out in 2010.

From next Monday, Internet hosts will be able to find each other without using the old IPv4 protocol. This means that, for the first time, a user will be able to visit a website without having to use the old IPv4 Internet. claranet is one of the few ISP's to provide IPv6 capabilities to its customers and has issued the following comment:

"Many ISPs haven't implemented IPv6 for a very simple reason - customers haven't asked for it yet," said Dave Freedman, claranet's Group Network Manager. "It is only now, with IPv4 exhaustion just around the corner, that many organisations are beginning to take this issue seriously.

Internet address space will start running out in two years time unless ISPs adopt the new version of the Internet Protocol, IPv6, across their networks. Although modern computers, servers, routers and other online devices are able to use IPv6, many ISPs have yet to implement the system. Meanwhile, the UK Government is failing to take the lead in preparing the country for IPv4 address exhaustion.

The Internet won't cease to function once IPv4 addresses have run out but it will face performance problems, not least those that could stem from Internet users being required to share the use of a single address. By contrast IPv6 offers vastly increased IP address space, ease of administration and integrated encryption capability.

PlusNet are celebrating today after winning the UK Internet Service Provider Associations (ISPA) charity five-a-side football cup from 2006's champions, claranet:

Plusnet overcame defending champions claranet in a thrilling final. After a goalless first five minutes Plusnet found the back of the net and despite claranetís best efforts managed to keep their 1-0 advantage winning the match and claiming the title.

The event is a great way to bring the Internet industry and businesses together to support charitable causes. This yearís ISPA event raised just under £4,000 for: The British Liver Trust, advocating on behalf of those suffering from liver disease and funding medical research; Net2work, which teaches vocational IT skills in deprived areas and LOHADA, a small, Tanzanian-led, non-governmental organisation serving young children at risk of going to the streets and disadvantaged elderly people in Tanzania.

Fourteen teams battled it out for the coveted trophy, with all proceeds going to charity.

The UK Internet Service Providers Association (ISPA) reports that claranet are gearing up to defend their ISPA Charity Football Cup, which was won in a final against AOL last year.

The third annual five-a-side tournament has been opened up to non-members this year and is due to take place on 27th September at Wembley.

Claranet has appointed Michel Robert to be its new Managing Director (MD). Mr. Robert was formerly European Solutions Director at Dimension Data and has been appointed to help boost the ISP's UK strategy:

He has been appointed to implement the claranet Group strategy in the UK and specifically to drive the growth of claranet UK's business IT services and solutions offering.

"As Managing Director of claranet UK, Michel Robert will be part of the team that consolidates claranet's position as a multi-national IT services provider," said claranet Founder and CEO Charles Nasser.

Despite being well established, claranet has been absent from the top of consumer charts since the dialup days when it began to focus more on business services. Though still reputable in comparison to cheaper alternatives, few in todayís the mass market would find a 10GB capped package costing £29.99 per month to be attractive.

Claranet has announced a successful connection to the Hibernia Atlanticís high performance cable network, which crosses the North Atlantic between London and New York City:

Through physical diversity, the network connection will offer reliability to claranetís business clients. The network resiliency of the connection will allow claranet to continue to operate industry leading service level agreements (SLAs) for its customers.

The full release is online at http://www.uk.clara.net/pressoffice/28112006.php

This agreement comes after claranet yesterday completed a major upgrade to its network delivering a ten-fold speed increase to claranet's core network.

The investment has seen the introduction of £2.3 million worth of the latest Gigabit (Gb) switch router (GSR) technology - the Cisco GSR XR. This router technology is heavily deployed in the United States and has been proven in claranet's laboratory tests. claranet is one of the UK's earliest adopters of this technology in a core network.

Please see the full release here: http://www.uk.clara.net/pressoffice/244112006.php

These recent announcements and website updates suggest that claranet may well be awakening from its otherwise dormant state. Over the past few years the ISP has done little to keep up with the consumer market and fallen behind, having once been among the best and most competitive providers.
