The following is the Global Threat Report for Q1 of 2011 from Cisco.

The Cisco Global Threat Report is a compilation of data collected across the four segments of Cisco Security: ScanSafe, IPS, RMS and IronPort.

The highlights for Quarter 1 2011 include:
  • 105,536 unique Web malware were encountered in March 2011, a 46% increase from January 2011
  • Malicious webmail represented 7% of all Web-delivered malware in March 2011, a 391% increase from January 2011
  • 45% of all malicious webmail resulted from Yahoo! mail, 25% from Microsoft Live/Hotmail, and only 2% from Google’s Gmail
  • Search-engine-related traffic resulted in an average of 9% of all Web malware encountered in 1Q11
  • 33% of search engine encounters were via Google search engine results pages (SERPs), with 4% each from Yahoo! and Bing SERPs
  • SERPs and webmail encounters are impacted by the popularity of a particular service and are likely not indicative of any heightened risk specific to that service
  • Likejacking increased significantly during the first quarter of 2011, from 0.54% of all Web malware encounters in January 2011 to 6% in March 2011
  • At 13%, Miley Cyrus–themed likejacking scams beat out all other celebrities and events in March 2011. Likejacking themes for Indian actress Nayantara were at 7%, while Charlie Sheen was at 3%, Justin Bieber at 2%, and Lady Gaga at 1%
  • At 4% of all Web malware encounters in 1Q11, website compromises that attempted to download the Hiloti Trojan were the most frequently encountered, followed by malicious GIF injections (3%). Website compromises related to the Lizamoon series of SQL injection attacks represented just 0.15% of Web malware encounters for the quarter
  • Though far less successful than in years past, SQL injection attempts continued to be the most prevalent event firing (55%) observed by Cisco Remote Management Services in 1Q11
  • Malware activity related to the MyDoom worm was the 10th most frequently RMS-observed IPS event in 1Q11, demonstrating that legacy malware can still pose a threat to unprotected systems
  • As expected, Rustock activity declined significantly over 1Q11, but, interestingly, the sharp decline commenced weeks prior to the botnet takedown
  • Following 4Q10 declines, global spam volume increased and then subsequently decreased during 1Q11, but levels remained above that of December 2010
  • With an increase of 248%, Indonesia overtook the United States as the top spam-sending country in 1Q11
Cisco’s Top 10 Signature Findings Q1 2011 
  • Generic SQL Injection                                                                                    55.03%
  • Web View Script Injection Vulnerability                                                           7.01%
  • Gbot Command and Control Over HTTP                                                           5.16%
  • B02K-UDP                                                                                                         5.20%
  • Cisco Unified Videoconferencing Remote Command Injection                        4.91%
  • Microsoft Internet Explorer Invalid Flag Reference Remote Code Execution    3.27%
  • Windows MHTML Protocol Handler Script Execution                                        2.47%
  • WWW WinNT cmd.exe Access                                                                         1.30%
  • Web Application Security Test/Attack                                                              1.19%
  • MyDoom Virus Activity                                                                                     1.16%
Note that the MHTML vulnerability described in Microsoft KB 2501696, IntelliShield alert 22310, and Cisco Intrusion Prevention System (IPS) 6.0 – 33379/0 also appears on the Cisco RMS top 10 signature events list for 1Q11. Microsoft released an update for this former zero-day vulnerability in April 2011 (MS11-026).

While a significantly occurring event in 1Q11, SQL injection attempts remained at a fairly steady pace throughout the quarter with the only notable increase occurring in the latter part of March 2011.

Although they represent a relatively small percentage of overall spam, phishing attacks pose a serious risk to security, both from a financial and sensitive information disclosure perspective. In 1Q11, attackers increasingly turned their attention toward phishing Twitter accounts.

This interest in Twitter credentials is likely due in part to Twitter users’ acceptance of shortened URLs. By compromising Twitter accounts, attackers can take advantage of shortened URLs to entice followers to visit malicious links the users might ordinarily view as suspicious. Such attacks are further fuelled by the trust engendered through social networking in general.
