IBM X-Force Report Reveals Unprecedented State Of Web Insecurity

IBM has released results from its X-Force 2009 Mid-Year Trend and Risk Report. The report’s findings show an unprecedented state of Web insecurity as Web client, server, and content threats converge to create an untenable risk landscape.

According to the report, there has been a 508 percent increase in the number of new malicious Web links discovered in the first half of 2009. This problem is no longer limited to malicious domains or untrusted websites. The X-Force report notes an increase in the presence of malicious content on trusted sites, including popular search engines, blogs, bulletin boards, personal websites, online magazines and mainstream news sites. The ability to gain access and manipulate data remains the primary consequence of vulnerability exploitations.

The X-Force report also reveals that the level of veiled Web exploits, especially PDF files, are at an all time high, pointing to increased sophistication of attackers. PDF vulnerabilities disclosed in the first half of 2009 surpassed disclosures from all of 2008. From Q1 to Q2 alone, the amount of suspicious, obfuscated or concealed content monitored by the IBM ISS Managed Security Services team nearly doubled.

“The trends highlighted by the report seem to indicate that the Internet has finally taken on the characteristics of the Wild West where no one is to be trusted,” said X-Force director Kris Lamb. “There is no such thing as safe browsing today and it is no longer the case that only the red light district sites are responsible for malware. We’ve reached a tipping point where every website should be viewed as suspicious and every user is at risk. The threat convergence of the Web ecosystem is creating a perfect storm of criminal activity.”

Web security is no longer just a browser or client-side issue; criminals are leveraging insecure Web applications to target the users of legitimate websites. The X-Force report found a significant rise in Web application attacks with the intent to steal and manipulate data and take command and control of infected computers. For example, SQL injection attacks – attacks where criminals inject malicious code into legitimate websites, usually for the purpose of infecting visitors – rose 50 percent from Q4 2008 to Q1 2009 and then nearly doubled from Q1 to Q2.

“Two of the major themes for the first half of 2009 are the increase in sites hosting malware and the doubling of obfuscated Web attacks,” Lamb said. “The trends seem to reveal a fundamental security weakness in the Web ecosystem where interoperability between browsers, plug-ins, content and server applications dramatically increase the complexity and risk. Criminals are taking advantage of the fact that there is no such thing as a safe browsing environment and are leveraging insecure Web applications to target legitimate website users.”

The 2009 Midyear X-Force report also finds that:

* Vulnerabilities have reached a plateau. There were 3,240 new vulnerabilities discovered in the first half of 2009, an eight percent decrease over the first half of 2008. The rate of vulnerability disclosures in the past few years appears to have reached a high plateau. In 2007, the vulnerability count dropped for the first time, but then in 2008 there was a new record high. The annual disclosure rate appears to be fluctuating between six and seven thousand new disclosures each year.

* PDF vulnerabilities have increased. Portable Document Format (PDF) vulnerabilities disclosed in the first half of 2009 already surpassed disclosures from all of 2008.

* Trojans account for more than half of all new malware. Continuing the recent trend, in the first half of 2009, Trojans comprised 55 percent of all new malware, a nine percent increase over the first half of 2008. Information-stealing Trojans are the most prevalent malware category.

* Phishing has decreased dramatically. Analysts believe that banking Trojans are taking the place of phishing attacks geared toward financial targets. In the first half of 2009, 66 percent of phishing was targeted at the financial industry, down from 90 percent in 2008. Online payment targets make up 31 percent of the share.

* URL spam is still number one, but image-based spam is making a comeback. After nearing extinction in 2008, image-based spam made a comeback in the first half of 2009, yet it still makes up less than 10 percent of all spam.

* Nearly half of all vulnerabilities remain unpatched. Similar to the end of 2008, nearly half (49 percent) of all vulnerabilities disclosed in the first half of 2009 had no vendor-supplied patch at the end of the period.
