The security implications of IPv6
T
he pool of IPv4 addresses is quickly being exhausted. Yet today IPv4 still carries the majority of Internet traffic. And while organisations are now beginning to migrate to IPv6, switching poses a series of security challenges.
There are several important issues that IT administrators must be aware of during a changeover, including: IPv6
ICMP vulnerabilities; multiple protocol stack vulnerabilities; the lack of experience in countermeasures for IPv6 attacks; hacking tools that now support IPv6; IPv6 multicast vulnerabilities; IPv6 header information vulnerabilities; and tunnelling IPv6 through IPv4 networks. Keith Barker explains these issues in detail. Full story on page 5…
Getting lost on the Internet: the problem with anonymity
T
he Internet was never designed with anonymity in mind. In fact, the very design of the system allows for easy tracking, at least as far as an IP address.
Early on in the net’s development, questions were being raised about
privacy and anonymity. Steve Gold outlines the historical foundations of the issue, in the very development of the Internet, and goes on to explain why achieving anonymity is so difficult. Full story on page 10…
Classic enterprise IT: the castle approach
T
here have been proclamations for many years now that the centralised ‘castle’ IT model is no more. But there’s one thing that must remain in the ‘keep’ of core resources – the user’s identity.
Identity has become the new perimeter. Every organisation has a
core database of identities. The key is ensuring that users have a reliable way of proving their identities. Tim Brooks of Signify shows how your core resource that manages identity can be used to keep your organisation secure. Full story on page 14…
PandaLabs says the fight against cybercrime is being won
I
n the midst of all the doom and gloom that normally surrounds reporting
of cybercrime, security firm PandaLabs believes there is reason for optimism.
The research arm of Panda Security has just published research which suggests that international co-operation among
security agencies is beginning to pay off and criminals around the world are being brought to justice. “The start of the year has seen some serious cyber-attacks, including the hacking of the Twitter accounts of major Continued on page 2...

FEATURES The security implications of IPv6 5 For a while now, IPv6 has been touted as the answer to the problem of Internet address exhaustion. Its massive address space offers an IP for every device. But the slow, piecemeal roll-out of IPv6, and the fact that it is so poorly understood, is opening up potential weaknesses. Keith Barker explains how vulnerabilities in the protocol stack and implementations, and the appearance of dedicated hacking tools, are creating a major security problem. Getting lost on the Internet: the problem with anonymity 10 Every time you use the Internet, you leave traces. The system was designed to make connections, and sometimes those are tracks you’d rather not have lead directly to you. Steve Gold describes the net’s early history, how that led to the creation of organisations concerned with privacy and anonymity and goes on to explain why anonymity is hard to achieve even today. He concludes that you can never be fully anonymous on the Internet, but you can protect your privacy to a degree. Classic enterprise IT: the castle approach 14 The traditional method of protecting an organisation is no longer valid. Putting up defences at the perimeter has been rendered ineffective now that so many net-connected devices – such as smartphones – are coming into the heart of the organisation. Tim Brooks of Signify explains how the best approach is to make identity the foundation of your security. Interview: Colin Tankard – raising security awareness 16 Educating people about the need for security is a tough job. Many companies still do the minimum when it comes to securing their systems. And the general public seems equally reluctant to adopt more secure practices. Colin Tankard of Digital Pathways discusses whether the public actually holds the key to improving security, by demanding better custodianship of their private data from the companies with which they interact.

Network Security
...Continued from front page organisations such as the BBC or Burger King, and one of the biggest attacks ever, targeting some of the world’s leading technology companies: Apple, Facebook, Microsoft and Twitter,” said Luis Corrons, technical director of PandaLabs. “But there have been some victories for security forces as well, including the arrest of a group of hackers accused of extortion using the infamous ‘Police Virus’.” The year started with the inauguration of a new European cybercrime centre, designed to co-ordinate law enforcement activities among member states. Also in January, the FBI published details of an investigation that began in 2010 and thwarted a gang of cyber-criminals who had infected more than a million computers since 2005. This operation stands out not least because of the co-ordination between security forces in different countries. The FBI had the support of police in Moldavia, Romania, Holland, Germany, Finland, Switzerland and the UK. According to PandaLabs, one of the most infamous cases of the past year or so has been the ‘Police Virus’. In February this virus once again hit the headlines, but this time for a very different reason. The Technological Investigation Brigade of Spain’s National Police, together with Europol and Interpol, dismantled the cybercrime ring responsible for the malware. This is no time be complacent though, the firm warns. “We noticed that the news mentioned the arrest of ‘the gang’ of cybercriminals, yet the information we have at PandaLabs points to the existence of several gangs responsible for these attacks,” said Corrons. “We reached this conclusion after analysing numerous variants of the malware over time, and observing significant differences between them. In short, we are afraid the Police Virus is not likely to go away anytime soon. Users shouldn’t lower their guard.” Nevertheless, new threats continue to appear. Kaspersky Lab has recently announced that it has uncovered a family of malware, dubbed ‘NetTraveler’. According to the firm’s report, this has been used in so-called Advanced Persistent Threats (APTs) to successfully compromise more than 350 high-profile victims in
40 countries. The targets include people working in multiple establishments in both the public and private sectors, including government institutions, embassies, the oil and gas industry, research centres, military contractors and activists. According to Kaspersky Lab’s report, this threat actor has been active since as early as 2004; however, the highest volume of activity occurred from 2010 to 2013. Most recently, the NetTraveler group’s main domains of interest for cyber-espionage activities include space exploration, nanotechnology, energy production, nuclear power, lasers, medicine and communications.

McAfee says it’s business as usual
U
nlike PandaLabs (above), McAfee’s report for the first quarter of 2013 says that it’s business as usual in the malware and cybercrime worlds. Mobile malware – which means Android – continues to rise, while most of the other threats are familiar names, with a few old-timers coming back into the picture.
The Facebook malware Koobface has made a reappearance. First seen in 2008 it has been relatively dormant for a year. But levels of infection tripled in the first quarter of 2013, reaching record levels. There’s also been a rise in Master Boot Record (MBR) infections, which aim to compromise storage devices at a low level, giving the malware full control over the system. After declining over the past three years, spam is also on the rise again, as is the pump-and-dump scam involving near-worthless stocks. In the case of spam, the senders are using ‘snowshoe’ tactics, spreading the sending across many domains in order to fool the reputation metrics used by anti-spam systems. As for Android: “Our count of mobile malware samples, just about exclusively for the Android OS, continues to skyrocket,” says the report. “Almost 30% of all mobile malware appeared this quarter. Malicious spyware and targeted attacks highlighted the latest assaults on mobile phones.” The full report is available here: http:// bit.ly/201306mcafee.
