Global Threat Report
July 2008 Key Highlights
Total Web-based malware blocks increased 87% in July 2008 compared to the previous month; 83% of July 2008 Web-based malware blocks resulted from compromised websites; 75% of July Web malware blocks were the result of SQL injection compromise; Clickthrough of malicious links in email represented 1.3% of malware blocks and impacted 95% of customers
July 2008 also bore witness to an increase in social engineering email scams designed to install malware on victims computers. 95% of ScanSafe customers fell for the scams and attempted to clickthrough to the malicious site, which represented 1.3% of all malware blocks for the month. Had the clickthroughs not been blocked, the resulting malware would have included backdoor trojans and rogue scanners—software that erroneously claims the system is infected in an attempt to elicit payment for removal. While the email involved characteristics typically associated with the Storm botnet, the timing of the attacks and other characteristics indicate a possible link to Asprox.
ScanSafe customers were and continue to be protected from the attacks discussed herein.

eb-based malware has increased significantly in 2008. In June 2008, ScanSafe reported a 278% increase for the first six months of the year. That alarming trend continued in July with the number of Web-based malware blocks increasing another 87% over the previous month. The majority of the increase in Web-based malware resulted from ongoing website compromises which represented 83% of all malware blocks for the month. 75% of all malware blocks were the result of SQL injection attacks, the majority of which were related to the Asprox fast flux botnet. The Asprox botnet is believed to have origins in Russia and has commercial interests ranging from spam and clickfraud to rogue anti-spyware software and backdoor Trojans.
Web-based Malware
Malware Block Stage Type of Malware
Other 24%
Exploit 54%
Iframe 22%
Observations
The majority of malware blocks resulted from compromised websites; 82% of blocks were for malicious iframes and javascript source references and the exploit code called by those references.
Types of Compromise/Exposure
Storm Scams 1% Other Malware Blocks 17%
Top Ten File Types Blocked
Longtail / Other Compromise 7%
SQL Attacks 75%
Observations
Overall, 83% of all malware blocks were the result of compromised websites. Viewed from a total blocks perspective, compromise via SQL injection attacks compromised 75% of all malware blocks. The bulk of these SQL injection attacks are carried out through the use of automated tools , via fast flux botnets. A corresponding increase in malicious spam, typical of botnets, was also observed in July. Clickthrough of malicious links in email believed to be related to the Storm botnet compromised just over 1% of ScanSafe malware blocks for the month.

Observations
The heatmaps above depict the location of all malware hosts (including botnet infected computers) which may be used to host malware or (more likely) to act as part of a fast flux network in order to mask the true origin of the hosted malware binaries. The first chart below reflects the geo-locale of malicious binary hosting domains excluding these botnet infected computers. The second chart below also excludes bot-infected computers and shows the geo-locale of password stealers and backdoor trojan hosts.
