The report doesn’t discuss how the web sites were hacked, but web application attacks have been a popular method of compromising websites, as operating systems and web server software have gradually become more secure. SQL injection attacks have recently become a popular method of compromising sites that use databases to dynamically generate content. At the start of January, at least 70 000 websites across a variety of private and public sector organisations were infected with malicious code. The code altered sites to deliver content from uc8010.com, a site hosted in China. The SANS Institute posted information about the gradual evolution of the SQL injection attack here: http://isc.sans.org/ diary.html?storyid=3823&rss. Other findings in the report included a focus on attacking web 2.0 applications using a mixture of techniques including mash-ups and unattended code injection. It also confirmed that the US, China, and Russia are the top three countries hosting phishing and crimeware sites.
Business worried about data loss - but probably not enough
B
usiness concerns over data loss have escalated considerably during the past year, according to a report issued by Symantec. In volume 2 of its its IT Risk Management Report, the company found survey respondents worried about the loss of data from security breaches.
“Data loss went from not even being an area of concern that warranted being in the survey last year, to being 46% of respondents expecting at least one serious incident per year,” said Jennie Grimes, senior director at Symantec’s IT risk management program office. However, that still leaves 54% of respondents expecting a data leakage incident only once every five years. Following a year of high-profile data losses in companies such as the TJX Group and in government organisations, 63% believe that a leak would have a serious impact on their business. A related issue, endpoint management, was also an area of serious concern, according
to the company. Over half of respondents to its survey expected to lose a laptop or other client within a year, but only a third of them have current configuration data for those laptops. “They only assess them annually in some cases,” said Grimes. The report sought to debunk what the company sees as four common misconceptions about IT risk. Risk in IT extends beyond security, encompassing areas such as availability, for example, said Symantec. IT risk management is also a continuing process rather than a discrete project. Technology alone is not enough to mitigate IT risk, added the report, arguing that well structured processes based on standards such as ITIL are a particularly important part of managing IT security risk. Technology alone is not enough to mitigate IT risk, added the report, arguing that well structured processes based on standards such as ITIL are a particularly important part of any IT risk management process. Unfortunately, the employee training and awareness that should accompany such processes is sadly lacking, said the firm. “The report implied where the respondents were generally weakest. One of the worst performing areas was training and awareness,” said Grimes. “And yet, we did research with IDC showing that if an organisation invests in training and awareness, they’ll get a 10% provable productivity gain. So you wonder why organisations aren’t looking at some of the less technology-bound answers?”
Ontario issues guidance on RFID use
O
ntario privacy commissioner Dr Ann Cavoukian has issued a set of guidelines for the use of RFID tags in the healthcare sector. The report, produced in conjunction with HP, highlights concerns over RFID privacy, but suggests that the benefits of the technology are great enough to make it worth navigating the security risks.
The report, RFID and Advocacy − Guidance for Healthcare Providers, separates the use of RFID tags into three broad applications. The first, tagging things, carries no significant privacy implications, it says. Continued on Page 20...

NEWS / EVENTS ...continued from page 2 The second, tagging things attached to people, carries some moderate privacy issues, while the third, tagging people, is an area of extreme controversy. Guidance offered by the report includes asking questions during the system design and information stage. Such questions include whether personal information is stored on a tag, whether the tag will be close to compatible unauthorised readers, the length of time that records are retained in analytic or archival systems, and the ability of tags to be disabled after use. When discussing the tagging of individuals, the report recommends asking whether the tags will be part of an “open loop” system involving multiple organisations, and whether the data will be stored or controlled by outside third parties. Victor Garcia, CTO of HP Canada, argued that designing suitable entitlements and audit facilities into back-end systems using the RFID data was crucial. “Technology can help to enforce policy and legislation by design applications in such a way that things like role-based access control are built into the application,” he said. “It needs to be properly designed.” However, not all health care institutions in the province were ready for such a move. “It depends on the hospital and the facility,” said Dr Cavoukian. Many hospital CIOs in Toronto are very capable, she says. “Some of the smaller facilities in more rural areas – that’s something we’ll have to work on.” Rank

essagelabs has identified a new kind of search engine-based spamming technique designed to get past many companies’ anti-spam filters. In its January 2008 intelligence report, it details a technique that takes advantage of Google’s ‘INURL’ tags, and its ‘I feel lucky’ search facility, which takes surfers straight to the site of the most likely search result.
The spammer crafts a search URL using the INURL tag to focus the search only on their domain. By including a tag which invokes the ‘I feel lucky’ function, the search URL takes the user directly to a page on their own web site, cirvumventing Google’s pages while also avoiding any reference to the spammer’s own domain in the URL. This makes it hard for anti-phishing toolbars or anti-spam filters to identify the spam email based on the embedded link. The technique, now used in 17% of all spam mail according to the report, correlates with a rise in text or HTML-only spam, and a marked decline in image spam. Text spam now accounts for 60% of spam, compared to just 30% last summer, while 38% of all spam is now HTML-based, slightly down from 50% last summer. Image spam has dropped to just 2% of all spam, just a tenth of its volume when it was at its high point in summer last year. Spam mail that uses file formats like PDFs, XLS, and MP3s to carry its payload now account for less than 1% of spam, said the report. Another significant finding was that stock spam has slowed to a crawl. It now accounts for just 2% of spam, following the indictment of stock spam king Alan Ralsky. Threat Type
